(ATC) that you have denied their request for access to your <br /> property located at 15400 Steinegul Road to sample the water from the onsite <br /> domestic well. <br /> ATC is currently conducting a site investigation of the former underground storage tank <br /> (UST) site located south of your property at 15634 Steinegul Road, known as Former <br /> Raymond Greer Construction. This property is a contaminated UST site listed with the <br /> EHD's Local Oversight Program (LOP). The LOP program is a state funded program <br /> the purpose of which is to oversee investigations and cleanups of sites where the soil <br /> and groundwater have been contaminated with petroleum hydrocarbons from leaking <br /> UST systems. <br /> There currently exist at the Former Raymond Greer Construction site eight <br /> groundwater monitoring wells that are monitored and sampled on a routine schedule. <br /> The groundwater samples collected from these wells, and from the domestic well on <br /> the property, are analyzed for specific petroleum hydrocarbon constituents. The results <br /> of these analyses are public record and are reported to the current and former property <br /> owner, the EHD and the State and Regional Water Resources Control Boards. They <br /> are available for review on Geotracker, the State Water Resources Control Board's <br /> internet database, which can be accessed at http://geotracker.waterboards.ca.gov/. <br /> The former owner of your property had allowed ATC access to sample their domestic <br /> well. The well was sampled and the groundwater analyzed once in 2003 and three <br /> times in 2008. Twice in 2008 the analytical results reported detections of methyl tertiary <br /> butyl ether (MtBE) in the water from your well at concentrations of 0.58 micrograms per <br /> liter (Ng/1) and 0.53 pg/I. These concentrations are below both the primary maximum <br /> contaminant level (mcl) of 13.0 Ng/I, and the secondary mcl of 5.0 pg/I for safe drinking <br /> water standards established by the California Department of Public Health. All other <br /> constituents analyzed for were reported as non-detect. <br />
