June 5, 1998 <br /> Page 5 <br /> • Groundwater Analysis. Following well development, water samples <br /> will be collected from the wells and submitted to a California State- <br /> certified'laboratory for analysis Groundwater samples will be analyzed <br /> for the presence of TPH-g, BTEX compounds, and MtBE <br /> • Well Surveying. Upon completion of well construction the wells will <br /> be surveyed by a licensed surveyor to mean sea level (± 0 1 inch) <br /> Lateral coordinates (± 1 inch) will also be surveyed Groundwater <br /> gradient will be interpreted utilizing wellhead elevations and depths to <br /> water <br /> • Physical Parameters Analysis. Select soil samples will be collected <br /> from exploratory soil bonngs and evaluated for physical parameters <br /> (i e , FOC, porosity, pH, etc) Examination of soil physical <br /> l meters <br /> is intended to aid in potential risk evaluation for encountered <br /> contaminants if the need anses based on results of further site <br /> 1 assessment Selection and submittal of soil samples for physical <br /> parameter analysis will be based on distinct changes in Iithology <br /> • Sensitive Receptor Survey. A sensitive receptor survey will be <br /> conducted to identify groundwater production wells or other potential <br /> receptors and migration pathways at or near the subject site <br /> • Off-site Domestic Well Sampling. One groundwater sample will be <br /> collected from a domestic well at 4514 Waterloo Road The sample will <br /> ' be analyzed for TPH-g, BTEX, and MtBE <br /> • Report. A report will be prepared after completion of the proposed <br /> scope of work The report will include boring logs, a well location map, <br /> a groundwater contour map, soil and groundwater analytical results, <br /> chain-of-custody documentation, and a summary of findings <br /> 920-122 1 Ai-MKPULL DOC <br />
