Division of Water Quality Appendix B Pesticides and Organics Evaluated in the Annual Pollutant Analysis Monitoring Executive Summary The Piedmont Triad Regional Water Authority (PTRWA) was formed by local governments surrounding the proposed Randleman Lake in 1986 to purchase water supply storage. Because of the potential construction of Randleman Lake, water quality of the upper Deep River area became of particular interest to the public. The Division of Water Quality (formerly, the Division of Environmental Management) performed a water quality monitoring study from July 28, 1992 to October 7, 1993. The results of this sampling effort were reported in Water Quality Moniforing Data For Waters in the Upper Deep River Area July 28, 1992 -October 7, 1993 (DEVi 1994). Because of the continuing interest in the water quality of this area, additional water quality sampling was performed in 1997. This summary discusses the data collected in 1997 and compares this data with earlier data collected from 1992 to 1993. Five monthly sampling events were conducted at nine different locations from May to September of 1997. Additionally, during the month of August, five fecal coliform collections were conducted for the purpose of determining compliance with the fecal coliform water quality standard. Summary tables are provided for all data that equal or exceed water quality standards as presently classified. Summary tables are also provided for all chemical data collected in 1997. No values greater than water quality standards for pH or dissolved oxygen were found during sampling performed in 1997. This was in contrast to the previous study, when dissolved oxygen values lower than the water quality standard of 4.0 mg/L were observed at RL2 and RL4. Fecal coliform concentrations exceeding the state standard of 200/100 ml were found at many stations during the 1997 sampling. The fecal coliform water quality standard (geometric mean value of 200/100 ml) was exceeded at five of nine locations. One additional location had more than 20% of fecal coliform bacteria concentrations greater than 400/100 ml which also exceeded the current water quality standard. Notably, all 1997 fecal coliform bacteria samples (10 observations) were greater than 200/100 ml at Muddy Creek at SR 1936 (RL8). Elevated fecal coliform bacteria concentrations were found at most locations under both low and high flow conditions. Metals concentrations greater than action levels for copper, zinc, and iron were found during the 1997 Upper Deep River study. Of the 45 observations collected for copper, 15 observations were greater than the 7µg/L action level. T~vo of these observations were upstream and 13 observations were found downstream of the High Point Eastside WWTP. The maximum observed copper concentration was 13 µg/L. Of the 45 observations collected for zinc, 14 observations were greater than the 50 µg/L action level. The maximum observed concentration for zinc was 110 µg/L. Self-monitoring data for metals at the High Point Eastside WWTP indicated elevated copper and zinc values in the effluent during the study period, however toxicity tests performed in July, 1997 indicated no toxicity. Total recoverable phenolics (phenols) above laboratory detection levels were found at all stations in the Upper Deep River study area in 1997. There is no numerical water quality standard for phenols for these Class C waters (only a narrative standard for protection of fish tainting). While the waters in this area are not currently classified for water supply, 36 of 45 phenols samples were greater than the state standard of 1.0 µg/L to protect water supplies from taste and odor problems due to chlorinated phenols. However, according to the water quality standards, phenols may be given different limits if they are demonstrated not to cause taste and odor problems and not to be detrimental to other best uses. The maximum observed concentration for phenols was 52 µg/L. Phenol observations greater than 20 µg/L were frequently observed. During the 1997 study, five samples from six different locations were collected for pesticides and organics analyses (tota130 samples). Laboratory analysis of these samples indicated many identified, tentatively identified and unidentified peaks and compounds (610 unidentified peaks). None of the reported laboratory concentrations for organics and pesticides appear to be in excess of the current water quality standards for Class C waters. While it is difficult to accurately summarize all of these results here, in general more organics and pesticides appear to be present in both Richland Creek and the Deep River below the influence of the High Point Eastside WWTP and further downstream in the drainage area. For example, Richland Creek below the High Point Eastside WWTP discharge (5 samples) had 202 unidentified peaks and identified compounds. Richland Creek above the High Point Eastside WWTP discharge (5 samples) had 79 unidentified peaks and identified compounds. In the previous water quality study of the Upper Deep River, violations of the state water quality standards for Lindane and Dieldrin were found. No violations were found in the 1997 sampling for these pararr~eters. As in the previous study, the highest number of unidentified peaks were found at RL4 which is located just downstream of the High Point Eastside WWTP. Elevated concentrations of nitrogen and phosphorus (nutrient levels) were found in the study area in 1997. All nutrient parameters were generally found in higher amounts at stations downstream of the High Point Eastside WWTP indicating that the WWTP is a significant contributing source of nutrients to the Upper Deep River area. Algal growth potential tests (AGPT) performed on six samples collected in 1997 demonstrated that all six sites had elevated AGPT values indicating eutrophication concern for potentially impounded waters. Introduction The Piedmont Triad Regional Water Authority (PTRWA) was formed by local governments surrounding the proposed Randleman Lake in 1986 to purchase water supply storage. Concerns about the present water quality in the Upper Deep River area warranted an earlier investigation of the Deep River and its tributaries by the Division of Water Quality (formerly, Division of Environmental Management). This investigation was performed from July 28, 1992 to October 7, 1993. A report was then produced documenting water quality conditions and entitled Wafer Quality Monitoring Data For Waters in the Upper Deep River Area July 28, 1992 - October 7, 1993 (DEM 1994). To supplement the data previously collected, additional water quality sampling was performed in 1997. Water quality sampling stations and parametric coverage are presented in Table 1. A map of monitoring locations and the proposed Randleman Lake is presented in Figure 1. Water quality samples were collected in accordance with Sfandard Operating Procedures Manual Physical and Chemical Monitoring. (DEM, 1996). All water quality samples were analyzed by the Division of Water Quality's Chemistry Laboratory. The following discussion summarizes results of the data collected in 1997 with some comparisons to previous monitoring efforts. Table 2 presents a summary of parameters that are greater than water qualit~r standards as presently classified. Table 3 presents the individual concentrations for water quality observations that are greater than standards as presently classified. Although the 1992-93 previous sampling effort was performed over a longer period of time, similar (low) flow conditions were present in the May to September time periods of both studies. Flow conditions were evaluated at a United States Geological Survey Station located at RL6.

This standard is, however, based on at least 5 samples in a 30 day period. For the purpose of determining if the standard of 200/100 ml was exceeded, five sampling events for fecal coliform bacteria were performed in a 30 day period from August 1, 1997 to August 27, 1997. The fecal coliform standard, which is a geometric mean, was exceeded at stations RL3 (708/100 ml), RL5 (381/100 ml), RL7 (252/100 ml), RL8 (2,158/100 ml), and RL9 (655/100 ml). Stations RL3, RL5, RL6, RL7, RL8, and RL9 also had violations of more than 20% of all samples examined greater than 400/100 ml. Fecal coliform bacteria results from these sampling events are summarized in Table 4.

All fecal coliform bacteria samples collected during the 1997 sampling study were above the 200/100 ml standard at RL8, located in Muddy Creek. The high fecal coliform bacteria values found at RL8 are also reflected in a frequency distribution table of fecal coliform bacteria values, presented in Table 5.

Data at stations both upstream and downstream of the High Point Eastside WWTP were graphed as well as data at a station in Muddy Creek and in the mainstem of the Deep River. Elevated fecal coliform bacteria levels were seen both in periods after rainfall and during prolonged dry periods. Total coliform bacteria results from August 1997 bacteria sampling runs are summarized in Table 6.

A graph of flow versus total coliform is presented in Figure 3. Similar to fecal coliform, data at stations both upstream and downstream of the High Point Eastside WWTP were graphed as well as data at a station in Muddy Creek and in the mainstem of the Deep River. Also similar to fecal coliform bacteria, elevated total coliform bacteria levels were seen both in periods after rainfall and in dry periods. Metals As observed in the previous study, metals concentrations higher than action levels for copper, zinc, and iron were found in 1997. Of the 45 observations collected for copper, 15 observations were greater than the 7µg/L action level. Two of these observations were upstream and 13 observations were found downstream of the High Point Eastside WWTP. The maximum observed copper concentration was 13 µg/L. Self monitoring by the High Point Eastside WWTP for toxicity performed in July, 1997 revealed no toxicity at a 90% effluent concentration over a 7 day period. A graph of flow versus copper is presented in Figure 4. Stations in the graph were selected to represent waters downstream of the High Point Eastside WWTP. From data presented in the graph, copper concentrations appear to be greater under low flow conditions at RL4, located in Richland Creek immediately downstream of the High Point Eastside WWTP. During 1997, 45 observations were collected for zinc, 14 of these observations were greater than the 50 µg/L action level. The maximum observed concentration for zinc was 110 µg/L. Eleven of these fourteen observations greater than the action level of 50 µg/L were also found downstream of the High Point Eastside WWTP. High Point Eastside WWTP self-monitoring data available for May to August, 1997 and 1997 Annual Pollutant Analysis Monitoring (APAM) revealed elevated copper and zinc values. These data are represented in Table 7.

Copper and zinc data from January 1993 to September 1997 at the Cape Fear River at N. C. Highway 42 near Corinth (station # B6160000) and at the Yadkin River at U. S. Highway 64 at Yadkin College, N. C. (station # Q2810000) were reviewed. At the Cape Fear River location, 10 of 54 copper observations were greater than the 7µg/L action level. Five of 53 zinc values at this Cape Fear River location were greater than the 50 µg/L action level for zinc. At the Yadkin River location, 8 of 34 copper observations were r :, Copper (µg/1) N ~ ~ ~ ~ ~ oC ~O ~t N O G1 .!

Iron concentrations in Piedmont streams are frequently elevated due to naturally occurring iron in the clay soils of the area. Furthermore, elevated concentrations of iron are fairly easy to remove during the drinking water process. However, in order to help characterize current iron levels in the Upper Deep River area, forty-five stream observations for iron concentration were collected during the 1997 Upper Deep River Study. Seventeen observations were reported as greater than the action level of 1 mg/L. A graph of flow versus iron is presented in Figure 5. Stations in the graph were selected to represent all areas of the study area except Richland Creek, where the High Point Eastside WWTP discharge is located. No clear relationship between flow and iron concentrations was suggested in the graph. Field Parameters (dissolved oxygen, temperature, pH, conductivity) No violations of water quality standards for field parameters were found during sampling performed in 1997. This was in contrast to the previous study, when dissolved oxygen values lower than the water quality standard of 4.0 mg/L were found at stations RL2 and RL8. Pesticides and Organics In addition to field measurements, biochemical parameters, nutrients, and metals analysis (often collectively referred to as conventional parameters), the 1997 Upper Deep River study also included monitoring for organic compounds which included organochlorine, organophosphorus, and nitrogen pesticides, and acid herbicides. Also included in the analyses were base/neutral and acid extractable organics, volatile and semi-volatile compounds. These analysis are collectively referred to as pesticides and organics. Because there are potentially thousands of organic compounds present in the environment, the DWQ tested for the most commonly occurring compounds by using an extensive array of analytical procedures on the 30 samples collected as part of this study. Samples were analyzed for the presence of approximately 90 different pesticides using gas chromatographic (GC) techniques (Appendix A). Pesticide evaluation included GC electron capture detection for approximately 50 halogenated pesticides and 16 acid herbicides. Additionally, approximately 25 organophosphate pesticides were evaluated using GC flame photometric detection techniques. In general, all pesticides are analyzed and quantified by comparisons with laboratory prepared standards. If relatively large concentrations of unidentifiable compounds are detected, samples may be further analyzed by mass spectrometry techniques. Routinely, approximately 66 semi-volatile organic compounds (Appendix A) are analyzed by mass spectrometry and quantified by comparisons with laboratory prepared standards. These particular compounds are included in the Environmental Protection Agency's list of priority pollutants. Occasionally, during laboratory analysis of the semi-volatile samples, compounds that do not match the laboratory prepared standards may be detected. These "unmatched" compounds can then be compared to a mass spectral library of approximately 41,000 compounds. If a compound matches a library compound it is tentatively identified and its i~ Iron (µg/1) 8 S o c~ N N ~-- .-~ v1 O i i i h ~, G~ -~ C ~ ~- ~ f I 3 ~' ~ C J ~ N ~ ~ ' ..: ` ~ ~ ~ ~ z ~ G4 ~ ~, o i ~ ~ ~ ~ ~~ I ~.

Similarly, there are approximately 54 volatile compounds (Appendix A) analyzed by GC electrolytic conductivity detectors and photo ionization detectors and quantified by comparisons with laboratory prepared standards. During laboratory analysis of the volatile samples, compounds that do not match the prepared standards may be detected. These compounds can also be compared to the same 41,000 compound mass spectral library. Since there are far too many individual compound analyses conducted under the overall umbrella of the pesticides and organics procedures to individually report, only those compounds that have been quantified by comparison to laboratory standards or have had concentration estimates reported by comparison with library identifications and internal standards are reported here. Thus the majority of the compounds, those that were not found and identified in the collected samples are not specifically listed in this summary document. Where laboratory analysis has indicated the presence of a compound but the compound could not be reliably matched to the available library, the compound is listed as an unidentifiable peak. Numerous unidentified peaks were found in pesticides and organics data collected in 1997. A list of the number of unidentified peaks that were found in this sampling effort is presented in Table 8.

In the previous water quality study of the Upper Deep River, violations of the state water quality standards for Lindane and Dieldrin were found. No reportable concentrations were found in the 1997 sampling for these parameters. As in the previous study, most of the unidentified peaks were found at RL4 which is located just downstream of the High Point Eastside WWTI'. Annual Pollutant Analysis Monitoring by the City of High Point was performed quarterly in 1997.

A list of pesticides and organics evaluated in the annual pollutant analysis monitoring is listed in Appendix B. Nutrients, Chlorophyll a ,and Algal Growth Potential Results Nutrients (nitrogen and phosphorus) were generally found in elevated amounts throughout the study area in 1997. In order to expand the nutrient data set, 1997 observations (5 for each location) were combined with the previous 1992-93 observations (14 for each location). Mean and median nutrient concentrations for all nutrient samples collected in 1992-93 and 1997 are presented in Figure 6. This figure shows that the highest concentrations for all nutrient parameters were found at RL4, just downstream of the High Point Eastside WWTP. The lowest nutrient concentrations in 1997 were generally found in the Deep River, at stations upstream of the confluence with Richland Creek. A graph of total phosphorus versus flow is presented in Figure 7. This graph suggests a potential inverse relationship between phosphorus concentration and flow. Insufficient data were collected to attempt nutrient loading calculations. One chlorophyll a concentration was found above the state standard of 40 µg/L for lakes, reservoirs, and other slow-moving waters. This elevated chlorophyll a value was 140 µg/L at RL6 (Deep River at SR 1921) on September 3, 1997. This elevated chlorophyll a value suggests potential eutrophication concerns if these waters are impounded. Algal growth potential tests (AGPT) were collected at six locations on July 8, 1997. The AGPT provides a very good estimate of bioavailable and limiting nutrients at the time of sample collection. The objective of the AGPT is to determine the total quantity of algal biomass of a test organism supportable by the test waters under optimum physical conditions and to determine whether algal growth is limited by either phosphorus or nitrogen. The measurements are made by adding a test algae, Selenastrum eal?ricornutum, to the test water and determining algal growth at appropriate intervals. An in-lake maximum concentration of 5 mg dry weight/L (maximum standing crop) of the test algae is a level that will reasonably assure protection from nuisance algal blooms and fish kills in warm water southeastern lakes (Raschke, 1989). A concentration of 5 mg dry weight/L converts to approximately 57 µg/L of chlorophyll a. In cases where the control maximum standing crop growth rates are > 5.0 mg/L, there are sufficient quantities of biologically available growth limiting constituents to support algal growth in excess of 57 µg/L chlorophyll a. Although the waters of the upper Deep River area are not currently impounded as a lake, AGPT results indicated that all six sites had results greater than 10 mg/L and would be considered highly eutrophic. The highest AGPT value was 211 mg/L, found at RL7. Most stations were nitrogen limited which is often due to excess phosphorus inputs from wastewater treatment plants and agricultural sources. AGPT results from the previous study also indicated eutrophication concerns with the potential for significant problems from algal response to excessive nutrients. The AGPT results collected in 1997 are listed in Table 10. ~~ )~igure 6 Upper Deep River Mean and Median Nutrient Concentrations (1992-1993 and 1997 data combined) NH3 TKN 1.25 1.20 1.15 1.10 1.05 1.00 0.95 0.90 0.85 ~ 0.80 E 0.75 0.70 j 0.6.5 ,~, 0.60 Y ~ O.s``S ~JQ 0.45 0.40 0.35 0.30 0is 0.30 0.15 0.10 0.05 0.00 to.,~ ..........................:..................................._..............__..... lam ................................

There is no numerical water quality standard for phenols for these Class C waters (only a narrative standard for protection of fish tainting). While the waters in this area are not currently classified for water supply, 36 of 45 phenols samples were greater than the state standard of 1.0 µg/L to protect water supplies from taste and odor problems due to chlorinated phenols. However, according to the water quality standards, specific phenolic compounds may be given different limits if they are demonstrated not to cause taste and odor problems and not to be detrimental to other best uses. The maximum observed concentration for phenols was 52 µg/L. Phenol observations greater than 20 µg/L were frequently observed. A graph of mean phenols values by station for the 1997 study period is presented in Figure 8. As seen in the graph, the highest mean phenols values for the study period were generally found at the more downstream stations in the study area with the highest mean value found at RL9. A graph of flow versus phenols is presented in Figure 9. Phenols values at stations upstream and downstream of the High Point Eastside WWTP and at a site in Muddy Creek were graphed. From results plotted in Figure 8, it appears that phenols values were higher in Richland Creek upstream of the High Point Eastside WWTP in higher flow conditions. No clear flow-related trend was seen in Muddy Creek and in Richland Creek downstream of the High Point Eastside WWTP.

This value was found at RL5 (Deep River at SR1129) on September 3, 1997. No turbidity standards violations were found during the previous study. In addition to samples collected for the 1997 Upper Deep River Study, monthly ambient monitoring was performed by the Division of Water Quality at RL4 and RL6. The Division of Water Quality's ambient monitoring program is designed to routinely sample approximately 380 stations located around the state. Monthly sampling visits are usually conducted at these stations to sample for a variety of parameters. Ambient data collected at RL4 and RL6 in 1997 are listed in Table 11. Ambient monitoring results were similar to that collected at RL4 and RL6 for the Upper Deep River Study. Fecal coliform bacteria values greater than or equal to 200/100 ml were found on 3 of 9 ambient sampling visits at RL4 and on 1 of 9 visits at RL6 in 1997. Eight of 9 copper samples collected for ambient monitoring in 1997 at RL4 were greater than or equal to the action level of 7 µg/L. At RL6, 5 of 9 ambient copper values were greater than 7µg/L. Seven of 9 zinc values collected at RL4 for ambient sampling in 1997 were above the 50 µg/L action level. At RL6, 5 of 9 zinc values collected in 1997 for ambient sampling were greater than 50 µg/L. Elevated nutrient values were found at both RL4 and RL6 during 1997 ambient sampling. To complete the reporting of all water quality parameters that were measured during the 1997 Upper Deep River Study, table 12 lists measured concentrations of miscellaneous chemical parameters for each static~:t by date, and shading is used to highlight those measurements that exceed water quality standards or criteria. Table 13 lists measured nutrient concentrations for each station. Table 14 presents measured metals concentrations for each station and shading is used to highlight those values in excess of water quality standards or action levels. Table 15 presents the results of physical measurements collected for each station during the study. „~ Table 11 Upper Deep River 1997 Ambient Monitoring Data Station Date Fecal Iron Cadmlu Chromlu Co er i Nickel Lead 21nc NH3 TKN NO2+NO31 Total P Colltor u /I u /I u /1 u /I u /1 u /I u /I m /I m /I m /I I m /I t/t0oml I RL4 01/23/97 <10 430 <2 e25 13 <10 <10 56 0.25 1 7.81 1.6 RL4 02/25/97 91 290 <2 <25 7 <10 <10 41 0.14 1.2 6.5i 1.7 RL4 03/25/97 <10 370 <2 <25 6 <10 <10 69 0.06 1 8.61 1 RL4 04/30/97 700 I <2 <25 131 <10 <10 40 2.1 3.1 0.871 1.4 RL4 05/22/97 200 2801 <2 <25 10 <10 <10 55 0.04 1.5 111 2 RL4 06/26/97 <10 4001 <8 <25 14 <10 <10 88 0.04 1.3 111 3.3 RL4 07/28/97 2400 200 <2 <25 101 <10 <10 230 0.22 1.1 171 1.8 RL4 08/27/97 45 820 <2 <25 101 <10 <10 98 0.13 1 12! 4.2 Rl4 09/29/97 180 680 <2 <25 13 <10 <10 110 0.06 1.1 121 2 RL6 01/23/97 45 790 <2 <25 6 <101 <10 30 0.19 0.6 4! 0.61 RL6 02/25/97 <10 510 <2 <25 41 <101 <10 10 0.19 0.8 1.71 0.23 RL6 03/25/97 62 910 <2 <25 6 <401 <10 67 0.05 0.5 2~ 0.22 RL6 04/29/97 3500 <2 <25 9 <10 <10 26 0.15 0.6 0.37. 0.17 Rl6 05/22/97 72 710 <2 <25 91 <101 <10 27 0.01 0.6 4.2' 0.73 RL6 06/26/97 27 3701 <2 <25 141 <101 <10 74 0.06 0.8 8.61 1.8 RL6 07/28/97 <10 5001 <2 <25 61 <101 <10 59) 0.63 1.5 6.6i 1 RL6 06/28/97 140 5601 <2 <25 8 <10 <10 73 0.051 0.9 11i 2.7 RL6 09/29/97 91 570 <2 <25 121 <101 <10 891 0.071 0.9 6.81 1.5 _ ~ ~ - S> 6Z ~ £S L 0- BZ -l OZt OOrL 00-L Otlt 9080[6 Bltl ~ L i ooos oozz o£lt toeoL6 e~tl s> s£ I s9 ~ tt 09 s'e I 9 0-t oon oosz oslt socacs e~tl S> C j LS I Ot !
