FNLS§ 2. As the noted on the SOIL ANALYSIS REPORTS,chemical analyses of the soil samples <br /> ral constituents that will influence nitrate loading from this project. The important parameters <br /> ading assessment are the organic matter,pH,cation exchange capacity(CEC),clay content <br /> long with nitrate-nitrogen content. <br /> NL § As noted,the organic matter in the soil is expectedly low since the property has not been <br /> farm-�the past five years. This suggests a very low potential for future nitrate-nitrogen loading from <br /> indigenous nitrogen soil content. Since septic effluent is composed predominately of ammonium(NH,), <br /> the pH, along with the CEC, are significant influences on ammonium molecules. <br /> The pH of the soil is moderately alkaline which may slightly inhibit ammonium formation and stability, <br /> and may create a small propensity for ammonia(NH3)formation. The CEC measures the ability of the soil <br /> to theoretically trap and hold ammonium molecules. Cation Exchange Capacities of the soil samples are in <br /> the high teens and twenties, which suggests there is some potential for the retention of ammonium <br /> molecules for microbial uptake, and suppression of nitrification. <br /> Table 1 below illustrates the subsurface soil characteristics encountered from the west end backhoe test pit <br /> and the east end backhoe test pit sample locations: <br /> TABLE 1 <br /> SOIL PROFILE CHARACTERISTICS AND / <br /> ANALYTICAL TEST RESULTS <br /> SAMPLE LOCATION, SAND,SILT AND CLAY SOIL NITROGEN pH AND <br /> SAMPLE DEPTH AND PERCENTAGES CONTENT CATION EXCHANGE <br /> (SAMPLE NUMBER) SOIL DESCRIPTION CAPACITY <br /> WEST BACKHOE TEST PIT 46%,26%,28% 4 ppm NOS N 7.4 20.1 meq/100g <br /> 18 INCH DEPTH Sandy Clay Loam <br /> (WTPl8) <br /> WEST BACKHOE TEST PIT 42%,30%,28% 7 ppm NO,-N 7.8 17.7 meq/100g <br /> 36 INCH DEPTH Clay Loam <br /> (WTP36) <br /> WEST BACKHOE TEST PIT 48%,28%,24% 4 ppm NO,-N 8.3 21.9 meq/100g <br /> 60 INCH DEPTH Loam <br /> (WTP60) <br /> WEST BACKHOE TEST PIT 50%, 26%,24% 7 ppm NO,-N 7.7 19.3 meq/100g <br /> 96 MCH DEPTH Sandy Clay Loam <br /> (WTP96) <br /> EAST BACKHOE TEST PIT 46%,28%,26% 3 ppm NO,N 7.5 15.0 meq/100g <br /> 18 MCH DEPTH Loam <br /> (ETP18) <br /> EAST BACKHOE TEST PIT 44%,26%,30% 6 ppm NO,N 7.5 17.6 meq/100g <br /> 36 MCH DEPTH Clay Loam <br /> (ETP36) <br /> EAST BACKHOE TEST PIT 50%,26%,24% 12 ppm NO,-N 7.2 15.9 meq/100g <br /> 60 INCH DEPTH Sandy Clay Loam <br /> (ETP60) <br /> EAST BACKHOE TEST PIT 46%,34%,20% 4 ppm NO3 N 8.2 19.8 meq/100g <br /> 96 INCH DEPTH Loam <br /> ETP96) <br /> Page -4- <br /> Chesney Consulting <br />
