HELMS MIDDLE SCHOOL SPORTS FIELD AND LANDSCAPING PROJECT PROJECT OVERVIEW • Project includes a full size football/soccer field, track, one handball court, four full size basketball courts and two small sided soccer fields. • Project also includes, via an agreement with the City of San Pablo, a building pad and associated utilities for a Community Center. • Following the demolition of the existing campus, a underground storage tank (UST) was removed and all contaminated soil was removed and disposed properly. • In preparation of exporting extra soil, a sample test was requested and resulted in certain levels of contamination. • In regard to the soil, two out of 12 samples were tested to contain less than .25% asbestos which is well below the “residential limits” used for a school facility. • Meanwhile, RGA, whom the District hired to perform peer review of all remediation activities, recommended that since only two out of 12 samples had detected asbestos, it would be prudent to retest the same area for naturally occurring asbestos (NOA). The plan here is to minimize the area that would fall under the Cal-OSHA (worker protection) requirements and possibly eliminate it if we receive “none detected” (ND) results. These results are expected by middle to end of next week. • In regard to soil contamination, test results indicated the existence of some low level contaminants. Test locations are shown on the map. • Contaminants found were removed, stockpiled and retested. • Based on these results, a decision was made to perform additional testing to determine the whole extent of the contaminated soil, which is under way. • In the meantime, additional testing (with sample taken below the bottom of the footings) was performed within the building pad area with location shown on the next slide. Results have come up negative.
