CPA0057 Sites RECEIVE 27 April 2016 <br /> West Charter Way and Lincoln Street 2��6 <br /> Stockton, San Joaquin County �IAY 0 <br /> ENVIRONMENTAL <br /> HEALTH DEPARTMENT <br /> Please copy the Central Valley Water Board on correspondence requesting access from <br /> the owner of the Dolly Madison property at 1426 Lincoln Street so we can verify a formal <br /> request was made and so we may follow up, if necessary. <br /> 7. Groundwater monitoring well SMW-14-49 appears to also be located on the Dolly <br /> Madison property and has not been monitored since 2010. Table 2.1 included in the <br /> 4Q15 Groundwater Monitoring Report indicates this well is to be monitored annually. <br /> Please insure this well is sampled in the next groundwater monitoring event and report <br /> results in the Semi-Annual Groundwater Monitoring report due 30 June 2016. <br /> 8. A review of the Site on the GeoTracker maps shows Huerta Elementary School and <br /> Edison High School across French Camp Turnpike, less than 500 feet southeast (down- <br /> gradient) of the leading edge of the groundwater pollution emanating from the Site. I am <br /> concerned the schools may be using water supply wells to water the numerous playing <br /> fields on these properties. By 30 June 2016, please provide contact information for <br /> personnel at the schools so I may confirm the source of water used at the schools. <br /> In summary, Central Valley Water Board staff expect to receive the following; <br /> • By 30 June 2016, submit the First 2016 Semi-Annual Groundwater Monitoring Report, <br /> including well construction details and analytical results for wells DMW-6, DMW-8, <br /> DMW-9, DMW-15 and analytical results from SMW-14-49. <br /> • By 30 June 2016, submit a Work Plan Addendum proposing a sufficient number of grab <br /> groundwater sampling points to complete horizontal and vertical delineation of petroleum <br /> constituents to the WQOs, and a scope of work for additional ART wells to address <br /> pollution migrating to the east of the former Texaco (Shell) property. Please provide <br /> contact information for Huerta Elementary School and Edison High School personnel <br /> that can confirm the sources of water used on these properties. <br /> • By 29 July 2014, please submit a draft Fact Sheet summarizing the remedial <br /> investigation and the corrective action proposed. In addition, please provide a list of <br /> names and addresses of the property owners and occupants to be notified within 500 <br /> feet of the groundwater pollutant plume. <br /> If you have any questions or concerns regarding the comments in this letter, please do not <br /> hesitate to give me a call at (916) 464-4619. <br /> CORICONDON <br /> Senior Engineering Geologist <br /> Underground Storage Tank Program <br /> Attachment ; example Fact Sheet <br /> cc; on next page <br />
