Bio-solids from the City of Graham Wastewater Treatment Plant were land
applied in eleven months during 2021; sludge application did not occur in February.
Applied metal calculations for 2021 reflect Wastewater Treatment Plant sludge only.
Effective January 1, 2021, Ferric sludge from the City of Graham Water Treatment
Plant is now applied on land provided by Synagro Southeast, Inc. of Clemmons, NC.
The metal loadings (ending 12/31/2020) were added to the 2021 WWTP bio-solids
to arrive at the ending 2021 accumulated metal totals.
Soil samples were collected in October 2021 and are included.
The TCLP Analysis sample was collected on October 7, 2021 and is
attached.
Quarterly Sludge Analysis was performed during March, May, July, and
October of 2021.
Items of note from 2021:

1. Information on all forms is for the Wastewater Treatment only. Synagro
results are no longer included in this report.
2. Mercury results for Fields 2, 3, 4, 6 & 7 are all reported as "0.000". A
separate page follows the "Field Summary Forms" that expands and verifies
these results.
3. Crop Yield results for 2021 are now included at the end of this year's report.
The City met the 40 CFR 503(B) rules for Pathogen Reduction (Class B, Alternative
1 for Fecal Coliform and Vector Attraction Rate by Specific Oxygen Uptake Rate.
The City of Graham uses the North Carolina Department of Environmental and

Understanding the Soil Report: explanation of measurements,abbreviations and units
Recommendations Report Abbreviations
Lime Ac exchangeable acidity
If testing finds that soil pH is too low for the crop(s) indicated, a lime recommendation will be given in units of either t3 boron
ton/acre or lb/1000 sq ft. For best results, mix the lime into the top 6 to 8 inches of soil several months before planting. BS% %CEC occupied by basic cations
For no-till or established plantings where this is not possible, apply no more than 1 to 1.5 ton/acre (50 lb/1000 sq ft) at one Ca% %CEC occupied by calcium
time, even if the report recommends more.You can apply the rest in similar increments every six months until the full rate CEC cation exchange capacity
is applied. If MG is recommended and lime is needed, use dolomitic lime. Cu-I copper index
ESP exchangeable sodium percent
Fertilizer HM% percent humic matter
Recommendations for field crops or other large areas are listed separately for each nutrient to be added (in units of K-I potassium index
lb/acre unless otherwise specified). Recommendations for N (and sometimes for B) are based on research/field studies K20 potash
for the crop being grown, not on soil test results. K-I and P-I values are based on test results and should be> 50. If they Mg% %CEC occupied by magnesium
are not, follow the fertilizer recommendations given. If Mg is needed and no lime is recommended, 0-0-22 (11.5% Mg) is MIN mineral soil class
an excellent source; 175 to 250 lb per acre alone or in a fertilizer blend will usually satisfy crop needs, SS-I levels appear Mn manganese
Mn-All Mn-availability index for crop 1
only on reports for greenhouse soil or problem samples. Mn-Al2 Mn-availability index for crop 2
Mn-I manganese index
Farmers and other commercial producers should pay special attention to micronutrient levels. If$,pH$, $pH, C or Z M-O mineral-organic soil class
notations appear on the soil report, refer to $Note:Secondary Nutrients and Micronutrients In general, homeowners do not N nitrogen
need to be concerned about micronutrients. Various crop notes also address lime fertilizer needs; visit Na sodium

may help you choose a comparable alternate. For more information, read A Homeowner's Guide to Fertilizer. P205 phosphate
S-I sulfur index
Test Results SS-I soluble salt index
WN weight per volume
The first seven values[soil class, HM%, WIV, CEC, BS%,Ac and pH]describe the soil and its degree of acidity. The Zn-Al zinc availability index
