• FOR • • AN INACTIVE WELL <br />FOOTHILL SANITARY LANDFILL <br />The Foothill Sanitary Landfill is owned by San Joaquin County and <br />operated by Foothill Sanitary Landfill, Inc. The site is operated <br />as a Class III municipal waste disposal site. The site contains an <br />old, inactive well located outside existing landfill boundaries <br />(see attached figure). This is an open bottom well with no casing. <br />The well depth was measured at approximately 166 feet, and the <br />diameter is approximately 4 feet. Water was not encountered in the <br />well. <br />The County proposes to abandon this well by filling the bottom 10 <br />feet with grout and filling the top 156 feet with soil from an on- <br />site borrow area. The 10 foot grout will be done by a licensed <br />contractor using a tremie tube. The soil filling will be performed <br />by landfill personnel. Work will consist of placing a soil <br />stockpile near the well with a scraper and pushing the soil into <br />the well using a front-end loader or dozer. Soil will be mounded <br />approximately 3 feet over the top of the well to accommodate any <br />settling that may occur. <br />R:\WES\EN\FH\ABNDONWL <br />
