The report concluded that it was possible to find a site on the <br /> campus that was no closer than 2,000 feet from any existing or abandoned gas <br /> station. The report determined that a site in the east end of Budd 2 parking lot <br /> was equidistant from all existing or abandoned gas stations that surround the <br /> campus and was an ideal location for a new well from a hydrogelolgic standpoint. <br /> Subsequently, the County, State, and oil company representatives agreed with <br /> the report's conclusion, and in December of 2000 a exploratory well was drilled In <br /> the parking lot. The pilot hole was electric logged, material samples retrieved, <br /> and water samples taken. The results of the analysis of water samples found <br /> that water from the exploratory well was free of hydrocarbons and would be <br /> acceptable for landscape irrigation. <br /> An estimate of the costs of constructing the well at that location was prepared in <br /> March of 2001. The estimate included costs of constructing the well and ancillary <br /> facilities as well as the cost of connecting the well to irrigation main lines and <br /> electrical service. With the site lying some distance from existing irrigation main <br /> lines and electrical service, these facilities would need to be extended to serve <br /> the new well. The cost of extending electrical and piping services was estimated <br /> to be $146,200. <br /> OBJECTIVES <br /> The purpose of this study is to investigate other potential sites on the Campus <br /> where the replacement irrigation well could be constructed. The investigation will <br /> focus on a site that meets the following criteria: <br /> 1, Generally as far away from all existing or abandoned gas stations as <br /> possible. <br /> 2. Generally as far away from the existing irrigation well as possible. <br /> 3. Close to the College's 12 kV electrical distribution loop. <br /> 4. Close to existing irrigation main line loop. <br /> 5. A minimum of 50 feet away from any existing storm drain or sanitary <br /> sewer line. <br /> 6. In an area that can easily be developed with minimal disruption to existing <br /> facilities, <br /> 7. In an area that can be easily accessed by service vehicles. <br /> DISCUSSION <br /> The conclusions reached in the original engineering study are still valid in that <br /> being as far away from any existing or abandoned gas station as possible will <br /> have the lowest risk for potential problems. The distance used to determined the <br /> likely area in the original report was 2,100 feet in any direction from any existing <br /> 1 <br />
