The <br /> recommended sampling interval for the first year is twice per year (April and October) then <br /> annually in October in subsequent years. During each sampling event the depth to ground <br /> water will be determined, A general minerals analysis includes alkalinity, chloride, electrical <br /> conductivity, hardness, pH, MEAS, sulfate, TDS, calcium, copper, iron, manganese, solium, <br /> zinc. <br /> WASTEWATER DISPOSAL SYSTEM WATER BALANCE <br /> VSlAtewater Production <br /> The Owens-Brockway facility operates 24 hours/days 7 days/weeks and produces a relatively <br /> constant amount of wastewater. The wastewater flow to the evaporation ponds consists of <br /> reverse osmosis (RO) backwash water and minor amounts of process water. <br /> Wastewater Disposal Capacity <br /> The three wastewater evaporation ponds have a combined surface area of approximately <br /> 24,965 square feet with an average depth of 7.7 ft. Total capacity of the wastewater <br /> evaporation ponds is 1.43 million gallons. Wastewater is discharged to Pond 1. As Pond 1 <br /> NOLTE ad AtUVJ.TM,—. <br />
