S&EC-Project #10,977..83. I. , Introduction Soil & Environmental Consultants; PA, (S&EC) has completed a preliminary agronomist "report fot the site referenced above.,. This report addressees the requirements set forth 'by _ .-15A the, (i) concerning-the'agronomic management plan for surface wastewater -,disposal, where spray irrigation field s are used 'as final wastewater receiver - sites. The purpose, of this report is to- perform an agronomic evaluation which. determines the, he feasibility of using portions of a 360.4c tract for additional spray field area as.,a receiyer:site for the future:expansion of the canning'facility. -:As part -of the study, fields ,were -'analyzed to determine agronomic limitations based on .hypothetical hydraulic , _loading: rates• of the proposed wastewater source. 'Industrial-.wastewater.generated from the Allens, -Inc.'-Plant.#7 canning facility is. current] y,appijed,to'-100.3 acres,of land locate&south of the canning facility. Wastewater is pre-treated by;passirig through a series of sedimentation and storage,basin"s before ,final land application.' 'In essence, wastewater flows -ouf of the;plant,'through a hydrosieve ! ,' --(separate' .'solids -from liquids) and into 3-acre settling lagoon where final sedimentation takes place. From -this sedimentation lagoon, -wastewater flows into a 27; acre storage -lagoon where it -awaits -final landapplication:.to:fescue'grass and Coastal bermudagrass by- :. spray 'irrigation: _ As currently,pennitted, this' site can ;apply 415,000 gallons of treated effluent;per day to the existing spray.fields.. Since,Allen_Canning Company wishes to increase production capacity of the facility; an additional' 360-ac tract' of land is currently . being considered-for;wastewater disposal. ,The proposed 360-ac parcel is located approximately 2 mi'les southwest of the existing canning facility on Rowan Road. The -new -spray field configuration currently under consideration can be found' in the"' hydrogeologicaI report completed by Eagle Resources.This scenario considers using a Charlotte Office: " .

As proposed, irrigation rates vary by zone,.ranging from 9.26- . - to 65.62 ;inches/year, accommodating a total daily wastewater flow up to _187,23.9 gallday. Monthly- and -annual. hydraulic loading rates by individual zones can be found in the-.. hydrogeological report completed by Eagle:Resources. S&EC-used these -proposed hydraulic loading "rates as a basis .for determining nutrient and heavy metal loading.on individual zones. ; ;• IL: Soil Sampling Methods and Proposed Cronnin�' Scheme The soils of the proposed application site's are described in the soil scientist's report dated February`14,-2008 by S&EC. Refer to..this report_and-associatedmaps for additional soil background information.- Based on tlie.soils evaluation, the,upland soils on this tract that. are within the proposed application areas are most similar to the Norfolk, Wagram, Goldsboro, Noboco, Tarboro and Kalmia soit series. After identification to the series level, the soils were.further categorized into map units based on similar morphological . characteristics and/or high frequency, of.association. - The identified map units were 1) Norfolk/Wagram,t2) Goldsb6ro/Noboo6 and,3) Tarboro/Kalmia. = - For agronomic sampling purposes, proposed spray areas were divided into two major' regions; based on historical cropping conditions.. Based on the soil scientist and., hydrogeologi'cai evaluation, approximately 66,.767ac of the entire tract",contains areas . deemed usable.for spray, irrigation. .The eastern half of the tract has been recently logged with'the intention of converting the- area into-a;hay.field. This spray area,is referred to as the "hay..field"-area.'The western half of the tract has been rotated between -corn, tobacco. and other row crops in recent years. This area is referred to as the "ag field". area. Composite samples of both areas ("ag field" and "hay field") were, created by collecting . -random cores from theupper 12 inches of soil throughout the two areas. Soil fertility, sample results are. report in Appendix l- and -summarized in Table 1. In the, soil, fertility f analysis --report, F=1 refers to the composite sample collected from the "a field." whereas. W-2 refers to -the "hay field" composite sample. Soils were not analyzed for nitrogen due ; to the dynamic nature, of soil N: Likewise 'soils were not analyzed for heavy metals given that historical crop management does not indicate any prior heavy-metal loading. -Table L, Soil Fertility Results.

"1 1'92 0.3 In' order- to maximize wastewater.,disposal from' a nutrient -use: standpoint, Coastal, bermudagrass lies been proposed as the final receiver crop-on'the spray areas.- Coastal ' bermudagrass, a hybrid bermudagrass variety, is a warm season perennial that grows quickly in the summer months. and -has a high capacity,to,assimilate plant nutrients, making it well -suited for'wastewater disposal" applications. Since bermudagrass goes . dormant in the late fall, wintertime wastewater application will be accommodated by over -seeding the bermudagrass with winter annual rye. Grass will be cut, baled and removed off -site on an "as -needed" basis. IV. Wastewater Analysis and Nitrogen Loading Laboratory analysis of wastewater samples was -provided to S&EC for the following dates: 3/31/2007, 8/3/2007, 12/10/07, 3/19/08, 7/7/08 and-.11/17/08. According to . facility officials, samples were collected from a discharge pipe that transfers wastewater from the, 27-ac storage_ lagoon to the existing spray fields. Nitrogen is the plant nutrient that is typically the most limiting to wastewater application'. A summary of wastewater-N fractions is provided in Table 2. Based on the data provided, the combined nitrate (NO3--N) and nitrite (NO2 -N) nitrogen has averaged approximately 0.36 mg.NO3-=N - . NOZ -N /L. Sample results indicate an average ammonium concentration of 15.80, mg NH4+7N /L. Wastewater organic-NN was calculated by"subtracting the wastewater ammonium concentration from the reported Total Kjeldahl Nitrogen (TKN) values. ,Table 2. -Summary of N-Fractions from Allens, -Inc.- Plant #7 Wastewater Analysis.

Most -likely, atmospheric and solution temperature play a dominate role in the extent to which organic-N mineralizes. Because the wastewater-N fractions vary by season, S&EC separated the summer and winter wastewater analysis for-N•loading calculations (Tables 3 and 4). Location _ . Date TKN NH3' . NO3 .

Since the wastewater will be applied to the proposed:areas through,a sprinkler spray system, some ammonium-nitrogen.(NH4+-IN) will probably be lost via'ammonia volatilization. S&EC assumed an ammonia volatilization co' fficient.of 0.5 for the present analysis... According to the wastewater analysis; a significant proportion of wastewater=N is present as organic-N. , Since the wastewater lagoon is considered a facultative anaerobic system, an N-mineralization coefficient, of 0.3 5was used for determining.PAN for the months of March -September: Using these estimates, the wastewater plant.available nitrogen (PAN) for wastewater applied during the;period of Mar'ch-September was calculated as follows: . 0.06'mg NO3"-N + NO2--N /L + 0.5(23.16 -mg NH4 +-N/L) + 0.35(29.49 mg organic N/L) = 21.96mg: PAN/L..: - In order to determine PAN for,wastewater applied from October -February, S&EC chose to use a'smaller N-mineralization. factor. to accourit for the relatively lower microbial . activity that occurs:duiing the cooler months of the winter. Brady and Weil (1999) have = ; i suggested that surface soil temperature typically. varies according to atmospheric temperature (Appendix 2a). Climate data obtained -from the Clinton,�NC 2S weather stationTrom 1936. 2006 shows how mean monthly temperatures (calculated from.average daily temperatures) vary by month (Table.5). Like many biologically -mediated reactions; N-mineralization is Heavily 'dependent upon soil temperature (Tisdale et. al, 1999; Appendix 2b)'. -.According to Stanford et. al.(1977), an increase in temperature of 10°C ' , will cause,N-mineralization rates to double within the -range of 5'C-35'C (Appendix 2c). Conversely, microbial activities would be reduced by an equivalent rate as. temperatures, - decrease_ . Other, researchers have attempted to quantify the effect of temperature on • microbial activities (Doran and Smith, 1987;"Appendix 2d). In incubation experiments conducted at temperatures ranging from 5°C-35°C; Stanford et. al. (1972) obtained mineralization ratio constants (k) of 0.009. to 0.055, varying in a linear fashion according ' to soil temperature (Appendix 2e).By applying, their data results to the Allen's Canning Facility, the N-mineralization rate constant would be equal to ,0.026 at a temperature of 16.40C(mean daily temperature for month of October) and would be equal to 0.041- at a -- temperature of 26.21 °C (mean daily temperature for month of July). Therefore,'the rate constant for the month of October would be approximately 38% lower than the o 'theretical maximum rate constant,based on temperatures in. the month of July. In order to obtain a temperature adjusted.N-mineralization rate for the winter months' (October=February) at Allen's.Canning Facility, S&EC completed an analysis using estimates of relative microbial activity as affected by soil- temperature and reported' by .Doran and Smith (1987). Appendix 2f shows',a graphical representation of how the results were obtained. Results are also reported in tabular format in Table 5. These results suggest that October would have the highest relative microbial activity and hence the highest N=_ mineralization rate relative to the other winter months. By multiplying the "relative microbial activity coefficient" (as shown in Table 5) by the summer mineralization:coefficient (0.35), winter mineralization rate coefficients were calculated on a monthly basis. As a conservative approach, S&EC chose to use the calculated' October N-mineralization" rate (0'.20) .in determining PAN for all of the winter months at the"Allen's Facility. In reality, the', average N-mineralization rate from •October to February may be less than what is -used in PAN calculations (see Table 5). ; .Table 5.

Accordingly, all of the proposed PAN application rates. would be below the recommended PAN rates for Coastal bermudagtass and -winter rye production. Soil Sample Results and Nutrient/Heavy Metal'Loading Based on the results of sampled soils, the average surface CEC .of the "ag field" and "hay field" is2.8 and 2.7,meq/100g, respectively..'Although these values are considered relatively -low from a total nutrient holding"capacity standpoint; adding lime at the recommended rates (0.8-1.3 ton/ac) should increase the pH -dependant CEC and'ensure nutrient availabilityfor optimum plant uptake. - Since maintaining a pH of 6.0-6.5 is essential for ensuring optimal nutrient availability, soil pH -should be. measured on. an "'.-annual, basis. Lime applications, should follow recommendations made by the current soil analysis and on all fiiture soil samples. As_noted in the soil fertility test results, current.soil test phosphorus.(P) levels varied according.to past management,. Soil test P in the. "hay. field" is. categorized as "low", - according to the North Carolina index value, whereas the sampled "ag field" showed an -.index rating of "very high": - An index value. of ."very high" indicates that there -will be no' crop yield-response,with additional P applications. Although applying -additional phosphorus to the "ag field" area:does not pose any agronomic issues, the high soil, P, aevels may pose an environmental concern if the site is subject to soil erosion. However, y considering the proposed cover•crop and its beneficial erosion control properties, -as well as proposed stream and waterway buffers additional wastewater-P application should -not pose. a -high risk of P-loss. Soil erosion and phosphorus loss potential from each spray r zone could'be evaluated using the North Carolina Phosphorus Loss Assessment Tool (PLAT):. "Low",or "Medium" PLAT ratings -would confirm that additional P loading . would not present a limitation to the proposed wastewater application. Several other assumptions were also made in determining P loading on the proposed spray fields... Wastewater total phosphorus (TP) 'values, as summarized in_Table 6,. are composed of both organic and inorganic forms of P.. Since much of the wastewater -Pis.. probably'in an organic form, not all of the P will be immediately plant available. In addition; a significant- portion of inorganic wastewater-P. will. form. insoluble Fe and Al precipitates and/or -become strongly adsorbed to amorphous soil Fe minerals once land applied. Given these assumptions, S&EC estimates that 60% of the applied P will ; become,plant available (NCDA, 1999). Wastewater analysis'indicates an average concentration of11:53-mg,total P/L. Using these estimates, the total plant available phosphorus of the wastewater is; calculated as follows: 11:53. mg Total P/IJ x 2.29 x 0.60 = 15.85 mg P205/L. The proposed application ratesmould'supply 29-149 lb P205/ac during the Coastal bermudagrass-growing season (March I" -September 301h) ands-86 lb, P205/ac during the winter rye growing season (October Vt-February 28t). Annual. wastewater-P, 205 application rates,and estimated crop P205 removal rates -for all zones are = found•inAppendix 4.

Soil test results' suggest that the `.`ag field" has a "moderate'.' level of soil K; while the "hay field" has=a ".veryaow."-level of soil K. In the case of both, spray areas, additional K should be , supplied -with a commercial fertilizer in order'to maintain optimum K levels for bermudagrass production (Appendix 1): Having sufficient K in the soil is essential for. preventing winter..die-off of Coastal bermudagrass when.over-seeded with winter rye..__,. _ Calcium (Ca) and magnesium (Mg), two secondary; plant nutrients,•were also present in the sampled wastewater. Annual wastewater -Ca and Mg application rates and estimated for -all zones and for both options. are found in Appendix 4.. At the proposed loading rates, Ca would be`applied at a rate -of 69-490.1b/ac/yr. Since soil test results indicate "low" soil -Ca levels in, both the ."ag field" and the "hay field."; the addition, of wastewater. ; Ca will be beneficial to the crop growing, environment. Soil test results show "medium" levels of soil Mg in both sampled fields. Based on application rates, 37-261 lb'Mg/ac/yr will be applied. 'Similar .to Ca, the application of Mg will also be beneficial for maintaining optimal growing conditions.::.. . According to the soil•fertility analysis, the average sodium (Na) level of the "ag field" soils was 14 mg/kg soil (0:00006 nieq/100 cm), while the "hay field" soils averaged 12 mg/kg,soil (0.00005.meq/100 cm). Sodium levels above 15%0'of the CEC can be detrimental to crop production arid'to the soil structure in the surface horizons: The'soil fertility lab results indicate,that neither of these soils meets this, threshold level of sodium. The average sodium concentration of the wastewater samples is, 23 8 mg Na/L, with the calculated'sodium.adsorption ratio •(SAR) equal to 8.3. Waters with SAR values in this - range have'a moderate -risk of developing sodium related problems'in clay soils, but have - _ a low risk of sodium build=up iri'sa idy soils (U.S.'Salinity Labor-atory;1954).' Since the • . proposed wastewater will.be applied to soils with a loamy sand surface texture, there is a , low risk of developing sodic soils with continuous irrigation. Annual soil samples should" be taken .to monitor sodium status in the soil. ` Heavy metal loading and associated plant toxicities are not expected to be an agronomic concern based on the proposed wastewater application. Table 7 summarizes heavy metal content of the sampled wastewater. Appendix 5 contains proposed annual heavy metal loading'rates for zinc; nickel, chromium, and lead based -on proposed application rates. Cadmium, -mercury Iand arsenic did not'register above lab detection limits and -were not ` included'in site life calculations.. "Lead proved to be'the most limiting heavy metal,, with a. site life ranging from 50-354 years, depending on -zone irrigation rate. However, the average lead concentration was highly skewed by the wastewater sample dated 7%7/08. '.Future -wastewater samples may demonstrate an average lead concentration much lower . than the average reported here. - Table 7.'

' t . - Subsoiling should be considered on areas .that have received heavy traffic or Where' . 4 plowpans have'developed from prior tillage.' Following de till' lirrie, phosphorus and potassium fertilizer should be ,applied arid incorporated into the seedbed as recommended by the soil, test report. Dormant.sprigging is the most economical, method' of establishing large areas of bermudagrass, although sprigs will .not begin to grow until late March. - When planting in the winter months', sprigs should .be covered with up to 2 inches of soil to protect them from frost. ' Live sprigs (stolons with green tops) can be planted in the'late spring after the threat. of frost has past. Although bermudagrass can be established using live sprigs until late summer, early planting dates will ensure strong rhizome (underground. stem) growth, essential --for' wintertime survival.: Only high quality sources -of sprigs certified by North Carolina Crop Improvement Association should be. used for establishment. To -optimize establishment; 30. to 40 lb/ac of starter nitrogen fertilize'rishoiild be applied once'growth begins and repeated six to, eight weeks later. Coastal bermudagrass should be cut every 4 to 5 weeks or when it grows to 12-1.5 inches tall. Once bermudagrass is overseeded with winter rye -in the fall, grass. should be, cut to a height of 3 inches or Tess to encourage rye establishment.' In the early spring, grass is expected to turn green,' mowing height approximately two weeks.before bermuda should be reduced to-3/ to 1-inch to allow bermudagrass to 'recovery and 'out -compete the winter rye. Since bermudagrass is very intolerant to shade,'late spring cutting of winter - rye should be avoided as it may 'severely limit bermudagrass recovery. V:. Conclusions , Based on wastewater analysis and proposed irrigation rates, -none of the"PAN application rates .would .exceed the recommended PAN rates for the Coastal-bermudagrass/winter rye - crop rotation. The proposed, application rates ,would supply 3.9-207, lb PAN/ac during the Coastal, bermudagrass growing 'season (March ist-September.30. and'3=501b PAN/ac' ' during the winter rye growing season (October, Vt-February-28tn). ` Although soil test phosphorus levels in the "ag-field" area are, considered' "Very High",, the properisity;for P4oss should be.considered very low given the proposed cropping system combined with stream and waterway buffers. As,proposed, additional wastewater-P application should not pose a high risk of P-loss. Although not used in this ,analysis; the North Carolina Phosphorus Loss Assessment Tool (PLAT) could be used to = - model P loss from the site to 'confirm' a low risk of P-loss. ` -Based on'the previous soil test results, some of the fields are currently low in soil K and, could benefit from additional fertilizer inputs: In -some individual fields, -proposed waste applied K will not supply all of the recommended K and additional K should be supplied, with.a commercial fertilizer. Having sufficient K in the soil is essential for preventing winter. die -off of Coastal bermudagrass.wheri over -seeded with annual rye.. ; - . Soil samples demonstrated that soil heavy-metal concentrations appear to be,present at background levels. -,Heavy metal loading and plant toxicities are not expected to be an - agronomic concern based on the wastewater analysis.

FIGURE 7.23 This high school in Oklahoma has been built into the ground with only one side exposed. This design takes advantage of the high specific heat and low thermal conductivity of the over lying soils, keeping the school warm in winter and cool in summer with a minimum of energy used for; heating or air-conditioning. (Photo courtesy of R. Weil) When sufficient water is present to form a bridge between most of the soil particles, fur-: ther additions will have little effect on heat conduction. Heat moves through mineral, particles even faster than through water, so when particle -to -particle contact is' increased by soil compaction, heat -transfer rates are also increased. Therefore, a wet,' compacted soil would be the poorest insulator or the best conductor of heat. Here again. the interconnectedness of soil properties is demonstrated. Relatively dry soil makes a good insulating material. Buildings built mostly under-; ground can take advantage of both the low thermal conductivity and relatively high, . heat capacity of large volumes,of soil (see Figure 7.23). .: The significance of heat conduction with respect to field soil temperature is not dif ; . ficult to comprehend. It provides a means of temperature adjustment, but, because it is; x slow, changes in subsoil temperature lag behind those of the surface layers. Moreover;. temperature changes are always less in the subsoil. In temperate regions, surface soils in -: general are expected to be warmer in summer and cooler in winter than the subsoil, s especially the lower horizons of the subsoil. Soil thermal conductivity can also affect air, temperature above the soil, as shown in Figure 7.24. Soil Temperature Fluctuations The temperature of the soil at any time depends on the ratio of the energy absorbed to that being lost. The constant change in this relationship is reflected in the seasonal,' monthly, and daily temperatures. The accompanying data (Figures 7.25 and 7.26) from, College Station, Texas, and Lincoln, Nebraska, are representative of average seasonal. , and monthly temperatures in relation to soil depth in subhumid temperate regions. Vertical and Seasonal Temperature Changes It is apparent from Figures 715 and 7.26 that considerable seasonal and monthly vari ,, ations of soil temperature occur,. even at the lower depths. The surface layer tempera;,, ; tures vary more or less according to the temperature of the air, although these layers are generally warmer than the air throughout the year.

The scene, looking down on a garden after an early fall snow storm, shows snow on, the leaf -mulched flower beds, but not on areas where the soil is bare or covered with thin turf. The reason for this uneven accumula- 'o'n"of snow can be seen in the temperature profiles. Having stored heat from the sun, the soil layers are often warmer than the air as temperatures drop in fall (this is also true at night during other seasons). On bare soil, heat energy is transferred rapidly from the deeper slayeis to the surface, the rate of transfer being enhanced by high moisture content or compaction, which increase the thermal conductiv- ity of the soil. As a result, the soil surface and the air above it are warmed to above freezing, so snow melts and does not accumulate. The leaf mulch, which has a low thermal conductivity, acts as an insulating blanket that slows the transfer of stored heat energy from the soil '4'tb the air. The upper surface of the mulch is therefore hardly warmed by the soil, and the snow remains frozen and accumulates. A heavy Covering of snow can itself act as an insulating blanket.

Note that the 7.5-cm soil layer is consistently warmer than the air above and that the 90-cm soil horizon is cooler in spring and summer, but warmer in the fall and winter, than surface soil. In the subsoil, the seasonal temperature increases and decreases lag behind changes registered in the surface soil and in the air. Accordingly, the temperature data for March at College Station suggest that the surface soil temperatures have already begun to respond to the warming of the spring, while temperatures of the deep subsoil seem to still be responding to the cold winter weather. The subsoil temperatures are less variable than the air and surface soil temperatures, although there is some temperature variation even at the 300-cm depth. The subsoils are generally warmer in the late fall and winter and cooler in the spring and summer than the surface soil layers and the air. This is to be expected since the subsoils are not subject to direct solar radiation. With a clear sky, the air temperature in temperate regions rises from lowest in the morn- ing to a maximum at about 2 P.M. The surface soil, however, does not reach its maxi- mum until later in the afternoon because of the usual lag. This retardation is greater and the temperature change is less as the depth increases. The lower subsoil shows little daily or weekly fluctuation; the variation there, as already emphasized, is a slow monthly or seasonal change. i 7.12 SOIL TEMPERATURE CONTROL The temperature of field soils is not subject to radical human regulation. However, two kinds of management practice have significant effects on soil temperature:- those that affect the cover or mulch on the soil, and those that reduce excess soil moisture. These effects have meaningful biological implications. Oryarlfc Mu;ches and Plant -Residue Management Soil temperatures are influenced by soil cover and especially by organic residues or other types of mulch on the soil surface. Figure 7.27 shows that mulches effectively! buffer extremes in soil temperatures. In periods of hot weather, they keep the surface soil cooler than where no cover is used; in contrast, during cold weather they keep the soil warmer than it would be if bare. The forest floor is a prime example of a natural temperature -modifying mulch. It is ,. not- surprising, therefore, that timber harvest practices can markedly affect forest soil temperature regimes (Figure 7.28). Disturbance of the leaf mulch, changes in water con- tent due to reduced evapotranspiration, and compaction by machinery are all factors that influence soil temperatures through thermal conductivity. Reduced shading after tree removal also lets in more solar radiation. 300 Soil Aer'atioti crud Temper•atrare �ro ' 5o l �erj<<; f and. fet l:22P5 , An Tnfrmlac�.o., +o Ncdr:e.►f j` Aa�rre.�.

Between 15 bars and air dryness, min- eralization and nitrification continue to decline gradually. For example, in a soil incubated at the wilting point (15 bars), more than half of the NH4+ is ni- trified in 28 days (Fig. 4.22) . At 7 bars, 100% of the NH4+ is converted to NO3- at the end of 21 days. Apparently, the Nitrobacter are able to function well even in dry soils. Obviously, soil moisture and soil aeration are closely related in their effects on nitrification. Temperature. Most biological reactions are influenced by temperature. The temperature coefficient, Q10, is 2 over the range 5 to 35°C. Thus, a twofold change in the mineralization or nitrification rate is associated with a shift of 10°C within this temperature range (Fig. 4.23). O.ptimurh soil temperature for nitrification of.NH4+ to NO3- is 25 to 35°C, al- though some nitrification occurs over a wide temperature range (Fig. 4.24). For off-season application of NH3 or NH4+ containing or NH4+ forming fertilizers winter soil temperatures should be low enough to retard formation of NO3-, thereby reducing the risk of leaching and denitrification losses. Fall applications of NH4+-containing or NH4+-forming fertilizers are most efficient when mini- mum air temperatures are below 40°F (4.4°C) or when soil temperatures are be- low 50°F (I VC). Even if temperatures are occasionally high enough to permit nitrification of fall -applied NH4+, this is not detrimental if leaching does not occur. In many ar- eas moisture movement through the soil profile during the winter months, is in- sufficient to remove any NO3- that may accumulate. For example, NH4+ sources may be applied in late summer or early fall in the Great- Plains before winter wheat planting. The same is true for spring cereal 160 120 E a a Z 80 O Z 40 7 14 21 ' 28' DAYS FIGURE 4.22 Effect of moisture levels near the wilting point on the nitrifica- tion of 150 ppm of N applied as (NH4) SO4 to a Millville loam and incubated at 25°C.

In humid areas water movement through the soil profile is excessive, and NO3— losses occur. Whether NH4+ can be applied in the fall without significant NO3— loss depends on local soil and weather conditions. It is possible to apply NH4+ sources in the fall in cool and/or dry climates to soils of fine texture without appreciable loss by leaching, provided that tempera- tures remain below 40'E The presence of NH4+ does not ensure its loss against leaching.

Carter3, D. T. Westermann3, and J. J. Meisinger2 ABSTRACT Previously reported studies on N fertilization 'of sugar - beets (Beta vulgaris L.) in southern Idaho revealed con- siderable variation among sites in amounts of residual soil NO, and N mineralized during short-term laboratory incubations. Consequently, the amount of N fertilizer needed to achieve near -maximum yields of sucrose dif- fered markedly. The purpose of this study was to deter- mine the feasibility of estimating amounts of - N min- eralized in the root zone during the season, taking into account site variations in temperature and soil water regimes. Residual soil NO,; N and mineralizable N to approximate rooting depth were estimated for 21 field sites in 1971 and six sites in 1972. The relative contribu- tions of these two N sources to total N uptake by the crop, in the absence of applied fertilizer N, were then - assessed. Estimates of N mineralized in the upper 45- cm soil layer for each successive month, AN, over a 6- month period were derived using the expression, AN/ At = kWN (k = fraction of N mineralized during each month, At, adjusted for average air temperature;'and W = the estimated soil water content expressed as a frac- tion of the available water storage capacity). Resulting estimates of the fraction of potentially mineralizable N converted to (NO;; + NHA+)-N between 1 April and 30 September ranged from 0.15 to 0.22 (mean ± S.D. 0.18 + 0.02) in 1971 and 1972. On the average, mature sugarbeets recovered about 73oJo of the estimated N min- eralized (6 months) plus residual NO,"-N. The relative contributions of these two sources of soil derived N, re- spectively, were approximately 66 and 75°jo, as estimated from multiple regression. analyses.

AMOUNTS of residual soil NO3 reflect manage- ment, N fertilization, and irrigation practices and influence the optimal level of N fertilizer needed for sugarbeets, (Beta vulgaris L.) (1, 2, 3, 4, 5). The re- mainder of the soil derived N is supplied through mineralization of soil organic N (1, 2, 3, 5, 11). Hence, both residual NO3 and mineralizable N must be measured to evaluate differences in N-supplying ca- pacities among, soils. This has been demonstrated clearly by Carter and associates (1, 2, 3) based on extensive field studies involving N fertilizer rates with irrigated sugarbeets. Amounts of mineralizable N potentially available to the crop may be assessed by various means. Car- ter et al. (1) incubated soils for 3 weeks at 30C and optimal water content (field capacity). Considering N uptake as a function of the amounts of N miner- alized, residual nitrate, and N supplied by fertilizer, together with a reliable estimate of . the optimal N re- quirement of sugarbeets (5.5 ± 0.5 kg/metric ton), these. investigators and their coworkers (1, 2) devel- oped a procedure for predicting N fertilizer needs that offers a basis for minimizing overuse. of N and the associated adverse effects on sucrose yield and quality. Another approach to estimating the contribution -of N mineralization of soil organic N has been sug- gested by Stanford et al. •(11). The potentially min- eralizable N, No, considered as a more, or less discrete fraction of total organic N, is estimated from amounts of N mineralized in successive incubations (8, 12) and is an estimate of the amount of N that will mineralize in infinite time under optimal temperature (35C) and optimal soil water content (approximately field capacity).

Using soils from field studies (1, 2, 3, 8) on N fer- tilization of irrigated sugarbeets in Idaho, the nitro- gen mineralization potentials of soils from each ex- perimental site (before N fertilization) were deter- mined by the ARS, Beltsville, Md. The purpose of this report .is to evaluate the feasibility of estimating N mineralized during the cropping season from a knowledge of N mineralization potential, No, average monthly temperatures, and estimates of average month- ly sail water regimes. This evaluation, based on data obtained from the plots that received no N fertilizer, involved determining the relation between N uptake by sugarbeets and amounts of available soil N (resi- dual NO3 and estimated N mineralized). MATERIALS AND METHODS Soil and Plant N Measurements During 1971, 32 irrigated N-rate experiments were conducted in southern Idaho. Detailed classification, potential rooting depth, previous crop history, and soil characteristics (pH, per- cent N, and percent organic matter) for most of these soils were reported by Carter et al. (2). Before applying fertilizer, each Table 1. Estimation of percent of No (mineralization poten- tial) mineralized based on average monthly temperature and soil water regimes (site 7, 1971).

Cor- responding 15-cm layers for 24 cores per site were composited. Deeper samplings of 30-cm increments were taken where the root zone was not restricted to 45 cm by a hardpan. In 1972, eight irrigated N-rate experiments were conducted on six soil types. Results from these experiments have been re- ported (3) along with details of soil sampling methods, soil classification, previous crop, and surface soil properties. The NO, content of all soil layers was determined as de- scribed in earlier reports (1, 2). The N mineralization potential, N., was estimated according to methods described to earlier publications (8, 13). Methods of obtaining yields of total dry matter (tops + crowns + roots), beets, and sucrose have been described (1, 2). Total N content of dry matter was based on separate determina- tions for the tops, roots, and crowns and does not include the estimated N content of fibrous roots as was -done in earlier publications (1, 2, 3). Effect of Temperature on N Mineralizationt The temperature coefficient, Q,,,, of N mineralization is 2 in the range of 5 to 35C (10), denoting a two -fold change in the mineralization rate associated with a IOC shift in temperature. For a given temperature, k is the mineralization rate constant in the first order expression, -dN/dt = kN (12). In this study, we used average monthly air temperatures, re- ported by local climatological stations, as approximate estimates of soil temperatures for the period 1 April through 30 Septem- ber. The relation of k (month-1) and temperature use([ in making our estimates is shown in Fig. I. The carve depicts a Q,,, of 2 and assumes an average k-value (35C) of 0.18 month-' (0.045 week-' X 4 weeks). Based on a large number of soils, the average k for 35C has been reported to be 0.054 ± 0.009. We arbitrarily chose the lower limit, 0.045 week-' or 0-18 month' for our estimates in this study. Using this base value, k„e = 0.09, k,,a = 0.045, and k,o = 0.023. Values of k for successive average monthly air temperatures were interprolated from the carve (Fig. 1) in estimating temperature effects on N mineraliza- tion as described below. Estimating Effects of Soil Water Fluctuations on N Mineralization The N mineralization rate is linearly related to the content of plant -available soil water in the range from field capacity to wilting percentage (9). Expressed on a relative basis, i.e., setting inaximitni mineralization rate and optiinal water content equal to one, the slope of the regression is approximately one for soils of differing textures and organic matter contents (9). For each of the sites, irrigation elates and rainfall records were recorded. This information was used in estimating the average fraction, W, of available soil water present in the root zone dur- ing each successive month. In general, we assumed that each irrigation replenished the available water storage capacity, i.e., W = 1. Effects of rainfall were estimated, although this con- tribution was relatively small, except for occasions in the :First 2 or 3 months of the growing season.

Among sites, the range in antecedent rainfall was 5 to 14 cm in 1971 and 1972. The cor- responding initial values of W were considered to be 0.5 and 0.8, and intermediate values of W on 1 April for each site were estimated by assuming a linear relation between antecedent rainfall and W within the indicated limits. In the interval be- tween irrigations, we assumed 70ofo depletion of the available water present after the preceding irrigation. The graphic procedure used for estimating W is illustrated in Fig. 2.

Estimates of amounts of N mineralized during each month, AN, were ob- tained from the rate expression, AN/At = kWN. The factors, k and W, were explained earlier. Initially, N = No (No is the N mineralization capacity of the 0- to 45-cm soil layer). For convenience in calculations, No initially is assigned a value of 100. During the first month, as illustrated in Table 1, kWN = 2.0 (last column). For successive months, No is reduced by the cumulative amount of N mineralized in previous months. In the example given (Table 1), the cumulative fraction of No mineralized during 6 months was 0.209. To estimate N actually mineralized, this fraction was multiplied by N„ e.g., 643 kg/ha X 0.209 = 135 kg/ha (site 7, 1971). RESULTS AND DISCUSSION Yield of roots, sucrose (percent sucrose X yield of roots), and N composition of total dry matter • (TDM) are presented in Tables 2 and 3. As indicated in foot- notes, results from several of the experiments may be questionable, although, as shown later, these data were useful in establishing the optimal N content of sugarbeets for maximum yield. In Table 4, locations of climatological stations closest to the experimental sites are given. Mean air temperature and rainfall recorded at these stations were used in adjusting N mineralization values. Also shown -in Table 4 are the amounts of NO3-N present, before planting and fertilization, to the indicated 306 ' AGRONOMY JOURNAL, VOL.- 69, MARCH-APRIL 1977 10 Table 5.

These depths approximate the root: zone and differ because of a restrictive hardpan layer of varying depth among sites. Degree of N Sufficiency as Revealed by'N Uptake Carter et al. (1), have established that maximum yield of sucrose or total dry matter is associated with a total uptake of approximately 5.5 kg of N/ton of beers. This observation offers a direct means of de- termining the degree of adequacy of soil derived N as ft varies among sites (Fig. 3). Here, the data from all sites (see Tables 2 and 3) were used to depict the regression of kg N/metric ton on percent N in the TD:A for 1971 and 1972 zero-N plots. Since the re- gression coefficients for -1971 and 1972 did not differ significantly, only the pooled regression is shown in Fig. 3. As estimated from the pooled regression, 5.5 kg N/metric ton corresponds to 1.55 percent N in the TDM. This percentage of N, associated with near maximum yield, is close to the value of 1.60'1 esti- mated from California results (7). In comparing suc- rose yields and percent N (Tables 2 and 3), it be- comes evident,' therefore, that the soil N supplied by most of the sites was inadequate for maximum yield of sucrose. Near adequacy of N is indicated for sev- eral sites, associated with a broad range (6 to 10 met- ric ton/ha) of attainable sucrose yields. From com- bined results for 1971 and 1972, the regression of "percent N in TDM" on "percent sucrose" is o/a N == 5.2 to 0.24 percent sucrose (r 0.71). Contribution of Residual Nitrate and Mineralizable Soil N to Plants In 1971 the amounts of residual NO3-N estimated for Sites given in Table 4 ranged from 36 to 243 kg/ ha (average, 127). Corresponding ranges for total N uptake (Table 2) were 82 to 318 kg/ha (average, 209). Assuming complete recovery, an average 61%) of total N uptake might be attributed to residual NO;,. In 1972 (Table 4) root zone NO3-N ranged from 18 to 130 kg/ha (average, 82) and N uptake (Table 3) ranged from 105 to 265 kg/ha (average, 192). Here, the average N uptake from NO3 appar- Site no.

The remaining N in the crop was derived largely from soil N mineralized during the growing season. The amount of soil N mineralized in the course of the season is dominantly influenced by temperature and soil water content, as mentioned earlier. These effects were estimated as outlined in Table 1, based on monthly adjustments derived from average air tem- peratures and estimated average fractions of potential- ly available soil water present during each month. The estimated percentages of No mineralized from April through September are shown in Table 5. In 1971 and 1972, sites 2 through 21, 101 through 160, and 201 through 222, respectively, occurred in the western, central, and eastern sections of southern Idaho bordering the Snake River. Corresponding average N mineralization percentages (-k standard deviation) as influenced by temperature alone, were 30.0 ± 1.5 (eastern), 26.8 ± 1.1 (central), and 24.5 ± 0.9 (eastern). Thus, differences among geographi- cal locations account for much of the overall variation in temperature effects on N mineralization. In both years, total N uptake was correlated signifi- cantly with amounts of NO3-N in the root zone (Ta- ble 6, ryi). In 1971 and 1971-72 combined, N uptake also was significantly correlated with No and with estimated N mineralized (Table 6, ry2). Because the variables, Xi and X2, are not strongly related (col- umn r12), their independent contributions to Y (114 uptake) can be evaluated with reasonable confidence using multiple regression analysis.

Statistical methods and symbols are those of Snedecor (6). Results in Table 6 verify the earlier conclusion of Carter (1, 2, 3) that both residual NOa-N and mineralizable N contribute to N uptake by sugar - beets. It is important to recognize that No consti- tutes a relative index of N mineralization capacity, unaffected by climatic factors, while N mineralized is an estimate of the N actually derived from No un- der prevailing temperature and water regimes. Hence, regression equations 4 and 6 (Table 6) are of particu- lar interest. The reliability of equation 5 is ques- tionable since it is based on only seven sites involving a relatively narrow range of No. The regression co- efficients in equation 4 and 6 indicate similar relative contributions, to N uptake, of residual NO3 (XI) and estimated N mineralized during 6 months (X2). A plot of observed vs. calculated (equation 4) N uptake values (Fig. 4) indicates several large deviations be- tween measured and predicted values for the 1971 data. These deviations are the net result of several com- bined sources of error such as: estimating residual NO3 and No from composited soil cores taken from the entire experimental area rather than individual check plots; estimating soil temperatures and soil wa- ter indirectly; and sampling and analytical errors in estimating the N uptake. The general success of equation 4 is encouraging considering these large sources of error. Although there is no absolute basis for indepen- dently evaluating the percent recovery (efficiency) of residual NO3-N and mineralized N, regression coeffi- cients (equations 4 and 6, Table 6) suggest similar relative contributions of N from these two sources. The regressions of N uptake (Y) on combined residual NO3-N and estimated N mineralized (XI -i- X2) are as follows: I971: Y = 0.73 (Xi + X2) - 2.6 (r = 0.80); 1972: Y = 1.09 (Xi + X2) - 6.0 (r = 0.87); and 350 300 o Y = 0.995 Y + 1.62 r = 0.80 250 'o 0 200 c 150 CL Z 100 Y=Y a > 50 00 50 100 150 200 250 Y, kp/ha:Colculated Fig. 4.

The regression coefficients indicate an overall aver- age efficiency of about 730/o which approximates the recovery that might be expected from near optimal N fertilizer rates applied to sugarbeets (1). CONCLUSIONS This study evaluates one approach to estimating the contributions of mineralizable soil N to the grow- ing crops in the field. The potentially mineralizable soil N is first determined in the laboratory, based on analysis of soils sampled from the portion of the root zone that contributes to N mineralization. In south- ern Idaho soils, most of the mineralizable organic N resides in the upper 30-cm layer, but significant amounts often occur in the (30 to 45)-cm layer. Hence, N mineralization potential was measured for each 15- cm layer to a depth of 45 cm. For each site, estimates then were made of the amounts of N mineralized per month, taking into account the average air tempera- tures and the estimated residual available water sup- ply present in the root zone. 308 AGRONOMY JOURNAL, VOL. 69, MARCH-APRIL 1977 The multiple regression of N uptake (Y) on resi- dual nitrate (Xi) and on estimated N mineralized dur- ing 6 months (X2) showed significant contributions from both sources. Moreover, in the equation (1971 data), Y - 0.75Xt + 0.69X2 + 1.3, similarity of re- gression coefficients suggests that the relative avail - abilities of the two sources of soil- N did not differ appreciably. Thus, we conclude that reasonable suc- cess was achieved in estimating N mineralized during the season in view of the approximations used in the analysis. LITERATURE CITED 1. Carter, J. N., M. E.

Soil humus, the largest component of soil OM, is relatively resistant to microbial degra- dation; however, it is essential for establishing and maintaining optimum soil phys- ical conditions important for plant growth. N Mineralization N mineralization is the conversion of organic N to NH4+ (Fig. 4.1). Mineraliza lion of organic N involves two reactions, aminization and ammonifacation, which oc- cur through the activity of heterotrophic microorganisms. Heterotrophs require organic C compounds for their source of energy. Mineralization increases with a rise in temperature and is enhanced by ad- equate, although not excessive, soil moisture and a good supply of 02. De- composition proceeds under waterlogged conditions, although at a slower rate, and is incomplete. Aerobic, and to a lesser extent anaerobic, respiration releases NH4'- Soil moisture content regulates the proportions of aerobic and anaerobic mi- crobial activity (Fig. 4.14). Maximum aerobic activity and N mineralization oc- cur between 50 and 70% water -filled pore space. Soil temperature strongly in- fluences microbial activity and N mineralization (Fig. 4.14) . Optimum soil temperature for microbial activity ranges between 25 and 35'C. The influence of soil moisture and temperature fluctuations on N mineralization throughout a growing season is shown in Figure 4.12.

Soil OM contains about 5% N, and during a single growing season 1 to 4% of or- ganic N is mineralized to inorganic N. As total soil N content increases, the quantity of N mineralized from soil organic N increases (Fig. 4.15) . Therefore, soil and crop management strategies that conserve or increase soil OM will result in a greater con- tribution of mineralizable N to N availability to crops. The quantity of N mineralized during the growing season can be estimated. For example, if a soil contained 4% OM and 2 % mineralization occurred, then 4% OM X (2 X 1061b soil/a— 6 in.) X (5% N) X (2% N mineralized) = 80 lb N/a Thus, each year, 80 lb N/a as NH4+ are mineralized, which enter the soil solution and can be utilized by plants or other soil N processes (Fig. 4.1) .

In minerali- m of soil organic N, the rate -limiting step is ionification, and, over much of the range from to 35' C, almost complete conversion of i,N to_ NOB-N normally occurs in aerated .

These soils and data referred to above are listed in Table 1. Detailed information on chem- ical properties and previous management of the soils is published elsewhere (Stanford and Smith 1972) . Duplicate .30-g samples of soil, mixed with equal volumes of silica sand, were placed in leaching tubes. As described previously (Stan- ford and Smith 1972), mineral N initially present was removed by leaching with an aqueous solu- tion of 0.01 M CaC12, followed by minus-N nutri- ent solution and suction (60 cm Hg) to remove excess solution. Three series of samples were in- cubated at 5, 15, and 25' C for 2 weeks, and samples again were treated as described above. Intermittent incubations and leachings were carried• out for four 2-week and four 4-week periods (cumulative, 24 weeks). Valdes of k for 5, 15, and 25° C were calculated from. the linear regression of log (No — Nt) on t (N. and Art expressed as ppm N in air-dry soil; t weeks of incubation) (Stanford and Smith 1972). The value of k (weeks 1) is obtained from the slope of the regression, k/2.303 (Stanford and Smith 1972). In making these calculations, it was assumed that the N mineralization potential, No , is unaffected by temperature. Moreover, it Ap- pears logical that the most reliable estimate of N,,is obtained by incubating soils at 35' C, since, as shown later, the proportion of No mineralized in a given time at this temperature greatly exceeds that at the lower temperatures. RESULTS AND DISCUSSION In Table 1 are shown the calculated mineraliza- tion rate constants derived from amounts of N mineralized in consecutive incubations over a period of 24 to 30 weeks at the indicated tern-. peratures.

Y Y Y, Y , Y changes approximately twofold for each 10-degree change in temperature. A more rigorous analysis of -the relation be- tween temperature and mineralization rate is de- picted in Fig. 1, using a modification of the Arrhenius equation (Bray and White 1957) : log k = log A - BIT (A is a constant, B is the slope of the regression, and ,T is the absolute temperature). The relation of log k to 11T in Fig. 1 represents the pooled regression for 11 soils derived from values of k and temperatures in Table 1 (Snedecor 1956). Pooling the results in a common regression equation is justified because regression coefficients, B-; do not differ signifi- cantly among soils (P < 0.01). The resulting equation is log k = 6.16 - 2299 (1/T), from which calculated values of k for 5, 15, 25, and 35° C are 0.008, 0.015, 0.027, and 0.049 weeks71. Qto values for 5 to 15, 15 to 25, and 25 to 35' C, respectively, are 1.9, 1.8, and 1.8. Because of the very low nitrogen mineralization rate at 5°C, estimates of k are less reliable than at higher temperatures. The regression equation calculated after omitting 5-degree data, log • k = 7.71 - 2758 (11T)., gave values of k for 5, 15, 25, and 35' C, respectively, of 0.006, 0.014, 0.028, and 0.056, and corresponding Qic values of 2.3, 2, and 2. Over the temperature range normally encoun- tered in the field, therefore, we conclude that Q10 , the "temperature coefficient" of nitrogen min- eralization (Bray and White 1957), is app mately 2.

The purpose of this report is to, perform an agronomic evaluation which determines the feasibility of using portions.of a 360-ac tract for additional spray field area as a receiver site for the future expansion of the canning facility. As part of the study, fields were analyzed to determine agronomic limitations based on hypothetical hydraulic loading rates of the proposed wastewater source. Industrial wastewater generated from the Allens, Inc.- Plant #7 canning facility is currently applied to .100.3 acres of land located south, of the canning facility. Wastewater is pre-treated by passing through'a series of sediment ation.and storage basins before final land application. In essence, wastewater flows out of the plant, through a-hydrosieve - . (separates solids from liquids) and into 3-acre settling lagoon where final sedimentation takes place. •From this sedimentation lagoon, wastewater flows into a 27-acre storage lagoon. wher& it awaits final land application to fescue -grass and Coastal bermudagrass by spray irrigation. As currently permitted, this site can apply 4154000 gallons of treated effluent per day to the existing spray fields. Since Allen Canning Company wishes to increase production capacity of the facility, an,additional360-ac tract of land is currently being considered for wastewater'disposal. The,proposed 360 'ac parcel is. located approximately 2 miles southwest of the existing canning facility on Rowan Road. The new spray field configuration currently under consideration can be found in the hydrogeological report completed by Eagle.Resources. This scenario considers using a new drainage system in -the eastern portion of the site to lower the water table, allowing Charlotte Office: Greensboro Office: 236 UPhillip Court, Suite C _ 3817-E Lawndale Drive Concord, NC 28025 Greensboro, NC 27455 Phone: (704) 720-9405 Phone: (336) 540-8234 Fax: (704) 720-9406 Fax: (336) 540-8235 for additional spray,area.- As;proposed, irrigation rates vary by zone;` ranging from 12.60 - ';Ao 75.75 inches/year,"accommodating a total'dail"y wastewater flow up -Jo 104,162 gal/day.

Annual"wastewater'Ca and Mg application rates and estimated for.all zones and for both options are found'in'Appendix 4.• At the proposed loading _ rates, Ca would be applied, at -a rate of 94-566 -lb/ac/yr. '•Since -soil test results indicate "low"soil CaJevels in both the "ag- field" and the "hay field", the addition of wastewater Ca will -he beneficial to the crop, growing environment.' Soil test results show."medium" levels of soil Mg in both .sampled ,fields. Based'on applicatiori-rates, 50-301 lb Mg/ac/yr will be applied. Similar to Ca, the application of Mg will also be beneficial for ; maintaining optimal growing conditions. ; t According to the soil fertility analysis; the". average sodium (Na) level of the "ag field" soils was 14 mg/kg soil (0.00006 meq/100.cm3.); while the "hay field" soils averaged" 12 - mg/kg soil (0.00005 meq/100 cm3). Sodium'levels above 15% of the CEC can be ` detrimental- to crop production and to the soil.structure in;the surface horizons. The soil fertility lab results indicate, that neither of these soils meets ihisthreshold level of sodium. The average sodium concentration of the wastewater samples is 238 mg Na/L, with the ` ~ calculated sodium adsorption ratio (SAR) equal �to-8.3. Waters.with SAR values in -this -range, have a moderate risk of developing sodium related ptoblems-in clay soils, but have a low risk of sodium -build-up n°sandy soil's (U.S, Salinity Laboratory, `1.954). Since the proposed wastewater will be applied to soils .with a �loaniy sand surface "texture, there is a low risk of developing sodic soils with continuous irrigation.. Annual soil samples should 'be'taken.to monitor sodium status in the soil. : Heavy metal loading -and associated plant tokicities are not expected to be an agronomic- concern'based on theproposed wastewater application. Jable 6 summarizes heavy metal content'of the sampled wastewater. Appendix 4 contains proposed'annual heavy metal - loading rates for zinc, nickel, chromium; and'lead based on proposed application rates. Cadmium, mercury arsenic did not register above lab, detection"1irnits and were not - included in site life calculations. , Lead proved 'to be the most limiting heavy metal,. with a site life ranging from 43-260 years, depending on zone irrigation rate.. However, the - average lead concentration was highly skewed by the wastewater sample dated-7/7/08.. ` Future wastewater samples may,demonstrate an average lead concentration much lower .than• the average reported here .Table 6:- Summary'Of Wastewater Heavy Metal Constituents.

The optimal time for establishing Coastal -bermudagrass using dormant sprigs is February through March., Dormant sprigging is the most economical method of establishing large areas of bermudagrass, although.. sprigs will not begin'to grow until late March. When Planting -in -the winter months, sprigs,should be covered with up to 2 inches of soil to protect them from frost. Live sprigs (stolons with green tops) -can be planted in the late spring after the threat of frost has past Although bermudagrass _can be established using: live sprigs until, lat e -summer, early planting dates will ensure strong rhizome (underground sfem) growth; essential for wintertime survival. Only high quality sources -of sprigs certified by North Carolina Crop Improvement Association should, be used, for . establishment. Coastal, bermudagrass-should be cut every 4 to 'S,weeks or when it grows to 12-15 inches tall. Once bermudagrass is overseeded with winter rye in .the fall; grass -should be cut to a • height of"3 inches or less to encourage rye establishment. - In the early spring, _approximately two weeks before bermudagrass is expected to turn green, mowing height should be reduced to'3/ to 1-inch. to allow bermudagrass to recovery and out -compete the winter rye. Since bermudagrass is very intolerant to shade, late spring cutting of winter 'rye should,be avoided as it may severely limit berriiudagrass recovery. V.: -Conclusions 1 'Based on wastewater analysis and proposed irrigation rates, none of the�PAN application rates. would `exceed the recommended PAN rates for -the Coastal-bermudagrass/winter'rye crop rotation.. The proposed application rates would supply 57-282 lb PAN/ac during the Coastal bermudagrass growingseaSon (March lst-September30th) and'4-50 lb PAN/ac during the winter rye,growing season (October lst-February 281h) Although soil test phosphorus levels in the "ag field" area are considered "Very High",, - r the propensity for P, loss -should be considered very low given the proposed cropping system combined with stream;and waterway buffers.

This permit modification does not request additional wastewater treatment capacity above the present limit of 415,000 gallons per day and consequently will not require the permitting and construction -of additional wet -weather storage capacity. This project was performed by Eagle Resources, P.A. under contract to Allens Inc. The area that includes the additional sprayfield capacity is referred to as the Rowan Road site which comprises approximately 353 acres lying south of Rowan Road and east of State Road 1933, approximately 3.6 miles west-southwest of Turkey, NC (Figure 1). The topographic relief at the site is flat, and elevations range from approximately 80 to 135 feet. All elevations in this report are reported relative to the 1988 North American Vertical Datum (NAVD88). Purpose This hydrogeologic study has been completed in support of modifications to the existing non - discharge permit as required by 15A NCAC 2T, and conforms to the criteria outlined in 15A NCAC 2T .0504(e). The purpose of the hydrogeologic study is to provide the necessary information and analyses to document the occurrence and movement of groundwater beneath and in the vicinity of the planned sprayfield(s), to determine the maximum area with suitable soils and maximum irrigation rates that can be applied while maintaining the minimum depth to the Seasonal High Water Table of one foot, and to evaluate and recommend compliance groundwater monitoring locations for the sprayfields. In particular, 15A NCAC 2T .0504 (e) Irequires the following information to be included: (1) A description of the regional and local geology and hydrogeology; (2) A description, based on field observations of the site, of the site topographic setting, streams, springs and other groundwater discharge features, drainage features, existing and abandoned wells, rock outcrops, and other features that may affect the movement of the contaminant plume and treated wastewater; (3) Changes in lithology underlying the site; (4) Depth to bedrock and occurrence of any rock outcrops; (5) The hydraulic conductivity and transmissivity of the affected aquifer(s); (6) Depth to the seasonal high water table; (7) A discussion of the relationship between the affected aquifers of the site to local and regional geologic and hydrogeologic features; Allens Canning Final Hydrogeologic Report.doc (8) A discussion of the groundwater flow regime ,of the site prior,to operation of the proposed facility and post operation of the proposed facility focusing on the relationship of the system to groundwater receptors, groundwater discharge features, and groundwater flow media; and (9) If the SHWT• is within six feet of the, surface, a mounding analysis to predict the level of the SHWT after wastewater application. Disclaimer Some analyses contained in this report relied upon data and information.provided by others. 'Eagle Resourceg P.A. makes no representations regarding the completeness, accuracy and reliability of that data and information. Approach ... The analyses documented in this report resulted from gathering and assessing existing sources of - information as well as from field investigations of geologic,- hydrologic, and soils conditions. The following tasks were, implemented in the approach: • Review of existing data and information" and basemap preparation • Construction of project Geographic Information System and Database. . • Field Investigation and Testing _ • Inventory of private water supply wells in ,the vicinity of the study area • Data Analysis and Modeling • Report preparation 1 i J Allens Canning Final Hydrogeologic Report.doc 2 r, - -1 EXPLANATION = Property Boundary MEIrrigation Areas -0e "A �x SR 0) 1907 S 1919; V.

The commercial GIS program ArcInfo® version 9.2 was used for this purpose. The project Geodatabase for this study included the standard environmental and water resources database used by Eagle Resources for such studies. This database is structured to be used with either Microsoft Access or Microsoft SQL Server. The database schema includes tables that contain information on topography, site development, well and sampling locations, water level measurements, results of chemical analyses of samples, results of hydraulic tests, boring logs of test holes, well completion information, logs of simulation model runs, and chemical analyses. Field Investigation Field investigations were conducted that included both the project site including proposed and new sprayfields as well as the surrounding area to obtain the necessary information to support the conceptual and numeric groundwater flow models prepared for this report and to document the presence of wells within 500 feet of the sprayfield boundaries. Identification of Wells within 500 Feet of Application Areas Site visits and examination of home sites and buildings aerial photos show five water wells within 500 feet of the proposed spray application area for the proposed sprayfield. One of these wells is located on the Rowan Road property, and the remaining wells are located on adjacent properties as shown on Figure 2. The available information on these five wells is shown in Table 2. If any additional wells are located during clearing and sprayfield development, they will be properly abandoned prior to commencement of sprayfield operation. Eight compliance monitoring wells have been installed in locations that are down -gradient from the proposed fields, and one well has been installed up -gradient from the fields. These well locations are within 500 Feet of the disposal boundary. Their locations are shown on Figure 2 and the construction details of the existing wells are shown in Table 2. The proposed compliance monitoring wells are located at the review boundary down gradient of the proposed sprayfield application areas. As shown on Figure 2, the review boundary is located midway between the boundary of the application areas and the compliance boundary. 15 Giese, G.L., Eimers, J.L., and Coble, R.W., 1997, Simulation of ground -water flow in the Coastal Plain aquifer system of North Carolina: U.S. Geological Survey Professional Paper 1404—M, 142 p. 16 Winner, M.D., Jr., and Coble, R.W., 1996, Hydrogeologic framework of the North Carolina Coastal Plain, in Regional Aquifer -System Analysis -Northern Atlantic Coastal Plain: U.S. Geological Survey Professional Paper 1404-I, 106 p. + 14 pls. 17 hLp://w".newater.org/Data and Modeling/Ground Water Databases/frametstnew.pbp Allens Canning Final Hydrogeologic Report.doc 1 5 We - Surface Sampson Elevation County Tax Site —ID Eastirig Ft Northing Ft Ft Owner Address- Parcel ID P.O.

These included 21 Cone Penetrometer (CPT) soundings, six (6 ) Hollow Stem Auger (HSA) borings,' 17 piezometers installed using push technology, four (4) monitoring wells and three (3) test wells - installed using HSA. The locations of these are shown in Figure 2 and the completion details are shown in Table 2. Additionally, Eagle Resources installed eight.new monitoring wells that -were " located so as to serve as compliance monitoring wells located at the review boundary based upon - . wetted area boundaries determined by this study. The new monitoring wells were installed by Protocol Sampling Services under subcontract to Eagle Resources using the hollow stem auger methods. The new monitoring wells are completed with above grade inch steel protective casings set in a concrete pad finished flush with the ground surface and are fitted with locking covers.'All wells and borings installed by S&ME that were able to be found have been properly abandoned by Protocol Sampling Services; a NC licensed Water Well Contractor. The completion records and well logs for, the new monitoring wells and piezometers as prepared by S&ME for the existing wells and by Protocol Sampling Services for the new monitoring wells are included as Attachment A.'

For the pumping test of RW-2, water level measurements were made in observation wells OW-1 which is . approximately 30 feet from RW-1 and in OW-2 which is approximately 55 feet from RW_ 4. For:e1 the pumping test on RW-2, water level measurements were made on observations wells OW=3 .. which is. approximately 30 feet from RW-2 and in OW-4 which is approximately 70 feet from RW-2. The results of the interpretation of these tests by S&ME are shown in Table 5. We have reviewed these results and concur with the methodology used and, the 'results. However, we note that for the test on RW-1, the value of storage coefficient calculated from the early-time_curve is larger than the value calculated from the late time curve, which does not agree with the theory of the method used. As all analyses used for the present report are steady state; no storage coefficient values are necessary, so this inconsistency is not important. S&ME also conducted a test to assess the hydraulic connection across the confining layer that occurs at beneath the site. This test was conducted by first pumping RW-2 for 6 gallons per minute for 24-hours and measuring the water level response,in the deep aquifer in RW-3 which is screened only in the deep aquifer., The second part of this test pumped RW-3 at 17 gallons per minute for 3 hours and measuring water level response in the shallow aquifer in RW-2 and OW- 3 and OW-4. Both of these parts of the test showed no measurable water level response in the non -pumped aquifer. Ksat Measurements S&EC measured the values of the saturated hydraulic conductivity (Ksat) of each horizon of the soil units judged to'be suitable for spray irrigation.

Figure 1 shows the modeled area and thelocation of the. new spray irrigation site. Hydrostratigraphic. Units The hydrogeologic framework for the conceptual model was taken from regional geologic,and : hydrogeologic studies9"O" l The site is underlain 'by approximately 15 feet of fine-grained,;,; . surficial materials referred to as the Surficial Aquifer that overly the Black Creek Confining Unit and the Black Creek Aquifer. Based upon the log of a deep well from the North Carolina Visual Hydrogeologic Framework as shown in,Figure 3, the Black Creek Aquifer is underlain by the Upper and Lower Cape Fear Confining Units and Aquifers and basement rocks. Well U35G shown in Figure 3 is located approximately 3.5 miles west of the Rowan Road site. A similar deep test well from the DWR database is located at Turkey approximately 3 miles northeast of the site and shows essentially the same elevation of formation tops and thickness of the Black Creek Confining Unit. The site hydrostratigraphy was estimated using logs of CPT soundings, test wells,, observation wells, and piezometers installed by S&ME5.6 that are -summarized in Table 2. Based upon these. it is apparent that the drainages at the margins of the Rowan Road site are eroded into the Black Creek Confining unit., Also based upon these logs the RW-3 is screened -in the upper part of the Black Creek Aquifer and the previously discussed test of RW-2 and RW-3 demonstrated the very low permeability of the Black Creek Confining Unit: For completeness, the logs and CPT soundings for reported by S&ME are included 'as Attachment A to this report.

The top of the Surficial Unit was taken as the land surface. The base of the Surficial Unit was approximated by subtracting 15 ft from the land surface. It also reflects the apparent configuration of the base of the Surficial Unit at the Site based on logs of piezometers and monitoring wells. The initial horizontal and vertical hydraulic conductivity of the Surficial Unit was estimated to be 12 ft per day based upon the aquifer tests of RW-1 and RW-2 reported by S&ME. As discussed subsequently, it was not necessary to modify these values to calibrate the groundwater model. Because the Surficial Aquifer was simulated using a single layer, the vertical conductivity is not explicitly included in the model equations. 19 hf p://wN�Nv.ncwater.org/Data and Modeling/Ground Water Databases/ftamework.php Aliens Canning Final Hydrogeologic Report.doc 13 Table 5• summarizes the initial hydraulic conductivity values used for the Surficial it, . and underlying units. 2) Black Creek Confining Unit: a low hydraulic layer that was assigned a uniform thickness of five (5) feet based upon the log of RW-3, the regional well U35G and leakance values reported by the USGS regional model for this unit10.

These were used for model calibration. Recharge and Discharge Recharge to the modeled area results from the balance between infiltrated .precipitation and evapotranspiration (ET) from the soil zone. Because all .of the watertable depths at the Rowan Road site are less than 10 feet the model was used to compute the net recharge rate as follows: 1. An average.rate of 39 inches per year of precipitation was applied to the top of the model based upon climatic records for Clinton, NC. 2. ET from groundwater was simulated using a depth -dependent function that decreased from the maximum valued of 3.6 inches per -year for.PET when.the watertable was at the land surface to zero at a watertable depth of 8 feet. As discussed subsequently, this extinction depth for ET was increased to 10 feet during model _calibration. Allens Canning Final Hydrogeologic Report.doc 14 3. The effective recharge rate was determined by subtracting ET from groundwater computed by the model from the precipitation that was applied as recharge. . This method of simulating recharge to groundwater when combined with the use of a drain boundary condition applied to the entire land surface of the model has been found to produce more realistic models than specifying an a priori recharge rate over the entire model. However the utility of this method requires sufficient number and distribution of measured water levels to check against during model calibration. This condition was met for the present study. The same method was used to determine the recharge rates under irrigated conditions for the mounding analysis discussed subsequently. Simulation Model The analyses documented in this report used MODFLOW-2000 which is developed and maintained as a public domain code by the U.S. Geological Survey (USGS) The model was developed, calibrated, and applied within the Groundwater Modeling System (GMSTM) which was developed for the U.S... Department of Defense, and which is a commercial product of ems- i, Inc. Model Grid The finite difference grid used for the simulation model covers the area shown in Figure 1, and comprises 230 rows oriented east west, 302 columns oriented nortn-south,3and 4 layers. The grid spacing over the entire model is 20 feet by 20 feet and corresponds to the previously discussed grid used to approximate the land surface. Layer one (1) represents the Surficial Aquifer and extends for a uniform thickness of 15 feet from the land surface. Layer two (2) represents the Black Creek Confining Unit and Layer three (3) the upper part of the Black Creek Aquifer. The top of layer one was taken as the land surface. The land surface was modeled using a 20 by 20 -foot grid constructed using the NC DOT 2-foot topographic contours outside of the Rowan Road property and site topographic contours provided by McConnell Associates Engineering for the interior of the Rowan Road Site. The top of Layer2 was determined by subtracting 15 feet from the land surface, the top of layer 3 Was determined by subtracting 20 feet from the land surface. The bottom of layer 3 corresponded to the bottom of the model and was set at a constant elevation of 50 feet NAVD 88. Boundary Conditions Drain boundary conditions were assigned to entire upper surface of model (the land surface). This boundary condition allows the site to drain if and when the watertable intercepts the land surface. The combination of the detailed topographic surface available from the surveyed site topography, and the 20-foot grid spacing provided a good representation of the elevation of the drains. The drain conductance was set at 10 ftZ/day/ft. In addition to the areal drain boundary condition used to simulate diffuse discharge to the land surface in the wetland and natural drainage courses, linear drainage features were used to simulate the five existing drains shown on Figure 2 as well as the proposed drain to be Allens Canning Final Hydrogeologic Report.doc 15 constructed in the. middle of Zone 18. Field surveys were conducted to estimate the depth that thee" existing drains are incised below the prevailing topography. The depth of incision ranges from 3 feet to 5 feet along portions of the long east west drain at the southern portion of the property as shown on Figure 2. An average depth of incision for the existing linear drains of 4 feet was used in the model. The proposed new drain in Zone 18 was" specified No flow boundary conditions were used in all`layers along the model boundary shown.in Figure 2 as well as to the bottom of Layer. 3. These correspond to either topographic divides or the thalweg of natural drainages. Model Calibration The calibration of a groundwater model is achieved by adjusting initial'estimates of hydraulic . , properties and boundary conditions to achieve an acceptable fit between simulated water levels' ;-,,= and observed water levels in wells that are representative.of the simulated hydrologic, units: This fitting of simulated to observed water levels is the same process'that is, used, in curve matching during pumping test analysis to determine aquifer properties. However, model calibration results in a more realistic representation of a hydrologic system than can be achieved by the use of type curves in aquifer test analysis. This is because numerical models do not require the use of simplifying assumptions regarding flow geometry, boundary conditions and, homogeneity -in. hydraulic properties that are necessary to construct the analytical solutions represented by the. type curves. The groundwater model was calibrated by matching simulated water levels in the 23 wells and piezometers measured on April 4, 2006 'as reported by S&ME6 and shown in Table I. All calibration and mounding analyses conducted for this report were steady state to demonstrate the maximum potential. water level elevations in response to hydraulic loading. This, approach is considered conservative because no credit is taken for the additional water that the Surficial Unit would accept into storage as the water table rises. No storage properties are required,for steady state analyses for any of the hydrostratigraphic units. This also eliminates another potential source of uncertainty in simulated water levels. Single Layer Approximation Test To assess the reasonableness of the preliminary model parameters reported by S&ME6, the hydraulic conductivity of layers 2 and 3 were set to an extremely low value of 0.00001 ft/day (3.5 x 10-9 cm/sec). This created essentially a single layer model. Examination of the fit to observed water levels showed that while acceptable, simulated values were generally higher than observed values. The first adjustment to correct this was to increase the ET extinction depth to 10 feet. While some improvement was achieved, simulated water levels were still too high. Manual incremental increases in the hydraulic conductivity of the Surficial Aquifer were used to improve the fit by examination of calibration statistics as shown in Table 6: While a value of the Normalized Root Mean Square Residual (NRMSR) of less than 10%.is generally considered acceptable, it was felt that a better fit might be achieved using automatic adjustment of hydraulic conductivity, of the Surficial Aquifer. Consequently, the automatic Parameter Estimation (PEST) component of GMS was used to determine the value of hydraulic conductivity of the Surficial Aquifer that provided the best fit when starting with values of 5 feet per day and 20 feet per day, or approximately one half and twice the initial estimated value of.1.2 Aliens Canning Final Hydrogeologic Report.doc 16 feet per day. The results of this analysis resulted in a best fit value of 18.4 ft/day as shown in Table 6.

Three Layer Model Calibration As discussed above, the field tests on RW-2 and RW-3 reported by S&ME and demonstrate that the Black Creek Confining Layer provides an effective hydraulic barrier between the Surficial and Black Creek Aquifers. The preceding PEST calibration of the single layer approximation model resulted in increasing the hydraulic conductivity of the Surficial Aquifer. To provide a more a complete hydrogeologic analysis and to test the reasonableness of using the value of 12 feet per day for this conductivity value from the on -site pumping tests, calibration of the three - layer model was tested. This calibration began by assigning a value of 0.00003 ft/day (1 x 10-7 for the hydraulic conductivity of the Black Creek Confining Unit and 20 ft per day for the Black Creek Aquifer as shown in Table 5. Calibration of the three -layer model was implemented by starting with the value of hydraulic conductivity from the PEST analysis of the single layer approximation model and manually adjusting it until the lowest value of NRMSR was achieved. Table 8 shows the calibration statistics for the three -layer model. Table 9 shows the values of the observed and simulated water levels and Figure 4 shows the visual goodness of fit, which is considered excellent. The best fit was achieved using the same value of 12 ft/day derived from the pumping tests on RW-1 and RW-2.

Hydraulic Mounding Analysis The calibrated model was used to simulate the water table configuration and the depth to water for by increasing the irrigation recharge to the reasonable maximum values that would not result in the watertable being less than 1 foot below any of the irrigation zones. The initial recharge rates for this process were determined by multiplying the geometric mean Ksat value for the most restrictive horizon for the most restrictive soil present in an irrigation zone. The geometric mean Ksat-values were determined by S&EC and are reported in the Soil Scientist report for the Rowan Road Sites. Initial boundaries of irrigation zones corresponded to boundaries of soil units as mapped by S&EC. However during the mounding analysis, it was necessary to further subdivide areas containing the same soil and to apply different recharge rates to the subdivisions. This process was used to maximize the irrigation capacity of the entire Rowan Road site, while keeping the Aliens Canning Final Hydrogeologic Report.doc 19 :i + Aaik•e recharge rates used less than the drainage rates recommended by S&EC in the Soil Scientist Evaluation reports.. Some irrigation zones (for example Zone 18) were developed to include more than one soil unit. In these cases, the applied recharge was restricted to that allowable for the most restrictive soil unit present in the zone. The recharge rates that resulted in the maximum irrigation rates for all 18 irrigation zones, that,,:;`:'-= resulted in a water table depth of greater than one foot under all zones were determined as.. - follows: 1. Apply the 801h percent total, precipitation'as recharge for all areas of the model outside of the irrigation zones; 2. Determine the maximum recharge rate for each zone that.fesults in the watertable being a minimum of one foot below the land surface within that zone and adjacent zones. This' rate is effectively the total of recharge from precipitation and applied irrigation; 3. Allow the model to compute the amount of recharged water removed by ET using the linear function of ET vs. depth to the watertable that sets ET at the maximum average PET at the land surface and"zero at a depth of 10 feet and tabulate the ET loss from each irrigation zone. - - •, 4. Compute the actual net drainage as the difference between the applied recharge and water removed by ET for each irrigation zone; and 5. Use the net drainage as the drainage in the water balance to compute hydraulic loading .rates for each zone. The results of the mounding analyses are shown in Figure 5 by the contour showing the limits of areas where the simulated depth to watertable is equal to one foot. Figure 5 also shows the simulated steady state water table configuration for the Surficial Unit for these loading rates. The mounding analysis was used to eliminate areas of the sprayfields that havethe potential for the permanent watertable under the 801h percent wettest year conditions to be less than one foot below land surface. There is one small area (less than 700 fe, or 0.'015 acres) in Zone 17 (Figure 5) that is a depression that needs to be filled with suitable soil to eliminate the potential for a water table less than one foot within the area.

These wells and a monitoring well previously constructed by S&ME (RW-5) will serve as the compliance monitoring system for the Rowan Road site. The details of the compliance wells are shown in Table 3 and their locations are shown on Figure 2. Wells RW-I, RW-2, RW-3, RW-4,, RW-6, RW-7, and RW-8 were installed by Protocol Sampling Services, a Licensed North Carolina Well Contractor under subcontract to Eagle Resources. Background Groundwater Quality Groundwater quality beneath the Rowan Road was assessed by S&ME on April 13, 2006 by sampling four (4) test wells and analyzing them for four of the seven parameters required by permit WQ0004268.

Canning Final Hydrogeologic Report.doc 23 Compliance monitoring well R-5 has been sampled and analyzed by Aliens in conjunction with the sampling and analysis required)by permit WQ0004268 since November 200720. The results of these analyses are also shown in Table 12. Note that the nitrate values in the test wells P-1, P- 4. and 6W-3 shown in Table 12 are significantly.higher than the values for OW-2 and P-15: These differences are attributed to the. fact that at the time the samples'were taken in OW-2 and P-15, the eastern part of the Rowan Road site in which these wells were located had not been cleared for cropping based upon reports by R. Wells and T. Langston of Aliens, and upon, Figure •; 2 of the S&ME Hydrogeologic Report6.. Conversely, based -upon the same sources, the`area: where the elevated nitrate values were detected apparently had been cropped for sometime. The elevated nitrate levels are likely the result of nitrogen fertilizer being applied in excess of agronomic demand. To further assess pre -irrigation groundwater quality conditions for the'Rowan Road site the compliance monitoring wells were sampled on November 17, 2008 as part of the regularly scheduled fall sampling that includes monitoring wells for the existing irrigation areas north of Rowan Road. The results of these analyses'are shown in Table 12. The nitrate levels in all the compliance wells except R-8 are below the NC 2L standard of 10 mg/l. Well R-8 is also in the area that has been cropped for many years, and this well is also up - gradient of all proposed irrigation zones. Conclusions A defensible conceptual hydrogeologic model of the Rowan Road site and'.surrounding areas has been constructed using available information from public domain sources, field investigations, and tests by other contractors for Aliens. A three-dimensional -groundwater flow model has been constructed and successfully tested against measured groundwater level measurements. The simulated groundwater flow patterns are consistent with the conceptual model. The agreement between measured and observed water level elevations is well within industry and NCDENR guidelines. Consequently the model can reliably be used to assess the likely average water table configuration and' depth to water table under conditions where irrigation is applied to the existing and expanded sprayfields. A uniform value of hydraulic conductivity equal to the value determined by a previous contractor from a long term pumping test was used in the simulation model for the surficial aquifer. Values for hydraulic conductivity of the underlying Black Creek confining Layer and the Upper Black Creek Aquifer were taken from regional studies by the U.S. Geological Survey. Acceptable model calibration was achieved by applying recharge from average precipitation and simulating evapotranspiration from groundwater as a function of the depth to the watertable. The calibrated model was used to develop the boundaries of 18 irrigation zones and to determine the maximum rate of recharge that under steady state conditions resulted in'a depth to water greater than one foot beneath each zone. The recharge used in the mounding analysis was the sum of the 801h% wettest year precipitation and applied irrigation water. 20Reid Wells, Personal Communication:" Monitoring Wells Spreadsheet' November 2008. Aliens Canning Final Hydrogeologic Report.doc 24 �r� lB "V-42G 5 The recharge rates resulting from the mounding analysis were used as the drainage rates in the water balance to determine the recommended hydraulic loading rates for each zone. The drainage rates were used to calculate an effective drainage coefficient (ratio of the drainage rate to the geometric mean vertical hydraulic conductivity or Ksat for the most restrictive horizon) for the most restrictive soil present in each irrigation zone. All the computed drainage coefficients and drainage rates are less than those recommended in the Soil Scientist Report for the Rowan Road Site.
