15 <br /> similar to that in water from wells at the factory was found in <br /> water from Well 4R East, a shallow well located just south of the <br /> factory. This water was of the calcium bicarbonate type. Water <br /> from Well 4R West, also located just south of the factory had a TDS <br /> content of 1 ,050 mg/1 and was of the calcium bicarbonate type . <br /> Barium content in water from this well was also detectable, but <br /> less than the MCL of 1 .0 mg/l. Water from both of these wells may <br /> have been influenced by waste disposal practices at the factory. A <br /> trilinear diagram plot indicates that except for Wells 3D and 3J, <br /> water from these wells is of an identical chemical type for major <br /> inorganic constituents as that of water in the main ponds. Water <br /> from Well 3H, located east and upgradient of the factory, had a TDS <br /> content of 610 mg/l and was of the calcium-magnesium bicarbonate <br /> type. Nitrate contents in water from Wells 3D, 3H, and 4R West <br /> exceeded the MCL of 45 mg/1 . The source of these high nitrate <br /> contents appears to be related to natural factors or irrigation <br /> practices, as opposed to percolation from ponds at the factory. <br /> PAYmeNT <br /> RECEIVED <br /> OCj 14 1992 PROPOSED MONITORING PROGRAM <br /> UIN <br /> PUBLIC �A T FSERV CES <br /> H <br /> ENVIRONMENTA�11Lfour lSlof the active supply wells are northwest and down- <br /> gradient of the main wastewater ponds, and nearby lands irrigated <br /> with wastewater. Well No. 4 also appears to be downgradient of <br /> some of the lime ponds. Wells 2A and 6A are in close proximity to <br /> the lime ponds, and their cones of depression should extend well <br /> beneath most of the lime ponds. Well No. 5 is farther away from, <br /> and apparently not downgradient of the lime ponds. The Stock Well <br />
