The T64 sample was collected while waste was present over native soil and <br />groundwater was exposed within the shallows of the trench base. <br />Three additional samples recently collected from the exposed water table are the following: NW at <br />location of T64, SE at the location of T70 and NE sample at location of MW -0. Analysis of the <br />samples included petroleum for and one sample for TTLC metals. The western and eastern water <br />samples were non detect for petroleum and eastern water sample had detections of metals below <br />their respective MCL. The analytical report and the tabulated metals data for water samples are <br />included. <br />F he property owners continuesto require the backfilling of excavation westernedges to <br />maintain <br />ihe stability of the exposed waste (particularly at the request of the neighbor) — AGE has the waste <br />currently covered with plastic and ready forbackfilling as directed by <br />William Little <br />California Professional Geologist #7473 <br />Advanced GeoEnvironmental, Inc. <br />Environmental • Industrial Hygiene • Geotechnical • Contracting <br />Phone: 800-511-9300 <br />Fax: 888-445-8786 <br />wlittle@advgeoenv.com <br />www.advgeoenv.com <br />This email/fax message is for the sole use of the intended recipient(s) and may contain confidential <br />and privileged information.
