The <br /> treatment system at this plant consists of flow equalization and mixing in a million-gallon (MG) <br /> pond and aeration and storage in an 84-MG reservoir. Treated wastewater is disposed of by spray <br /> irrigation. An inspection of this facility was conducted to sample tailwater from the land application <br /> areas and wastewater stored in the 84-MG reservoir. <br /> OBSERVATIONS AND COMMENTS: <br /> Nathan Evenson and I arrived at the Musco facility at approximately 10:00 a.m. and introduced <br /> ourselves to Kelly Hegman. The weather was mild, windy, and dry. <br /> Nathan and I collected samples of <br /> wastewater in the 84-million gallon reservoir <br /> -- from the upper 1-2 feet of water from the <br /> location shown in Figure 1. Kelly explained <br /> that process wastewater enters the 84- <br /> million gallon reservoir from near the base <br /> and that wastewater used for irrigation in the <br /> land application areas is taken from the <br /> upper few feet of the reservoir. Reservoir <br /> samples were analyzed for biochemical <br /> oxygen demand (BOD), total and fixed <br /> f° dissolved solids, and various inorganics and <br /> pesticides. The analytical results are <br /> X47 attached. <br /> Figure ]—Reservoir Sampling Location <br /> Approved: io: oaiarz <br /> w+somHALu�e INWaxogWWWr Wv alr gRpQW70406 We <br />
