I 7 <br /> Mr. Brian Cobb <br /> February 29, 1996 <br /> Page 2 <br /> Quarterly Monitoring Results <br /> Depth-to-water measurements and calculated groundwater elevations are summarized in Table 1 <br /> Groundwater elevations have increased in all of the monitoring wells relative to last quarter <br /> From the data collected on December 11, 1995, the groundwater flow direction was determined <br /> to be towards well MW-1 The hydraulic gradient across the site ranged from approximately <br /> 0.003 feet per foot (calculated between wells MW-4 and MW-1) to approximately 0.017 feet per <br /> foot (calculated between wells MW-3 and MW-1) Groundwater elevations and flow directions <br /> for December 11, 1995 are shown on Figure 1. <br /> TPHg was identified in two of the eight wells sampled (wells MW-3 and MW-8) at <br /> concentrations of 5,710 micrograms per liter (µg/L) and 370 µg/L, respectively Benzene was <br /> detected in two of the eight wells (wells MW-3 and MW-8) at concentrations of 1,000 µg/L and <br /> 10 µg/L, respectively Analytical results of groundwater samples are summarized in Table 1 <br /> and illustrated on Figure 1 The analytical laboratory report for the December 11, 1995 <br /> sampling event is included in Attachment A <br /> .
