The well is located approximately 150 yards from the <br /> southwest corner of the White Slough Water Pollution Control <br /> Facility (WSWPCF) holding ponds in 60 acres of pasture land. The <br /> well drilling logs are enclosed. <br /> The pasture is usually grazed by 75 cows and 75 calves. It is <br /> watered every ten ( 10) days during the irrigation season using a <br /> blend of WSPCF effluent and industrial system effluent which is <br /> predominantly cannery wastewater. <br /> The area directly surrounding the well site has a large abundance <br /> of ground squirrels with burroughs crisscrossing the entire area. <br /> The cement fill around the well goes down two feet with a <br /> bentonite fill extending an additional two feet down. The <br /> standing water level is usually only six to eight feet below the <br /> surface. <br /> Coliform contamination is most likely occurring due to the <br /> combinations of high ground water level, abundant cow manure, and <br /> numerous squirrel burroughs. <br /> The City also observing the rising coliform count over the last <br /> six months will be attempting to eradicate the squirrels <br /> immediately surrounding the well. Additionally the City will be <br /> constructing a 121 x 121 cattle proof fence around the well and <br /> fill the abandoned squirrel burroughs. This action should abate <br /> the observed rise in bacteria. <br />
