fC <br /> ESULTS AND DISCUSSION <br /> und in Table 1 below, are the test Results for each constituent tested (Column 1). Column 2 <br /> the test results of influent from the second compartment of the 10k gallon septic tank. <br /> Column 3 are the test results for the composite effluent from all three ES. For comparison <br /> purposes, Column 4 are the test results for the first biannual inspection on February 12, 2025 <br /> from ES #3 exclusively. <br /> TABLE 1 <br /> CHEVRON COMPLEX ONSITE WASTEWATER TREATMENT SYSTE 0 <br /> INFLUENT ANI) EFFLUENT ANALYSES <br /> Analytical Test Results: Analytical Test Results: Analytical Test Results: <br /> CONSTITUENT 2"'Comp.Septic Tank Effluent From All Three EnviroServer#3 Effluent From <br /> Influent 9/12/25 EnviroServers 9/12/25 2/12/25 <br /> (For Comparison Purposes) <br /> Total Alkalinity 707 mg/L 686 mg/L 23.6 mg/L <br /> Ammonia Nitrogen(NHa N) 125 mg/L 118 mg/L ND <br /> Biochemical Oxygen Demand 188 mg/L 61.8 mg/L 1.82 mg/L <br /> (BOD,) <br /> Specific Conductance(EC) 1860 µmhos/cm 1760 µmhos/cm 906 µmhos/cm <br /> Nitrate Nitrogen(NO;N) ND ND 59.8 mg/L <br /> Nitrite Nitrogen(NOZ N) 1.15 mg/L ND 1.22 mg/L <br /> Total Kjeldahl Nitrogen(TKN) 98.8 mg/L 85.8 mg/L ND <br /> Total Nitrogen 99.9 mg/L 85.8 mg/L <br /> pH 7.45 7.74 6.98 <br /> ND=Not Detected NT=Not Tested <br /> Additionally, Section 7.12 requests Average Daily Flows and Peak Flows. Peak flows are <br /> difficult to determine from this type of facility. Given that the facility is now open 24 hrs with <br /> the new owner, peak flows can still be assumed to take place in the morning, noon time and early <br /> evenings. Average daily flows have been determined by flow meters that have been installed on <br /> the three pressure lines leading to the disposal area. The following Table illustrates the flow <br /> volume totals and the average gallons per day(gpd) between the two measured dates: <br /> TABLE 2 <br /> Flow Meter Number Corresponding Meter Reading on Meter Reading on Total Volume Daily Volume in <br /> with EnviroServer Number September 12,2025 February 12,2025 Over 212 days Gallons per Day <br /> (Illustrated on Process Flow Diagram) <br /> 1 01,122,791 01,078,666 44,125 gals 208 gpd <br /> 2 00,786,600 00,610,900 175,700 gals 829 gpd <br /> 3 00,340,800 00,287,300 53,500 gals 252 gpd <br /> TOTALS 298,283 gals 1,289 gpd <br /> Page -2- <br /> Chesney Engineering, Inc. <br />
