2 0 GROUNDWATER MONITORING, SAMPLING AND ANALYSIS <br /> On December 31, 2004, to comply with quarterly groundwater monitoring requirements, Ramage <br /> Environmental monitored and sampled 9 of the 11 monitoring wells, and collected groundwater <br /> samples from the nearby cemetery irrigation well#2 Monitoring wells MW-1 and MW-8A were <br /> dry, and were not sampled <br /> 2.1 Groundwater Monitoring <br /> Depth-to-groundwater measurements were taken in of the accessible groundwater monitoring <br /> wells to evaluate groundwater flow and gradient characteristics The cumulative groundwater <br /> monitoring data are summarized in Table 1 <br /> The depth-to- roundwater beneath the site ranged from 47 21 feet below ground surface (b s) <br /> at MW-4 to 50 89 feet bgs at MW-7 MW-7 is the only well completed above-grade and <br /> protected with a monument casing The groundwater elevation beneath the site ranged from a <br /> high of 30 25 feet below mean sea level (MSL) at MW-2 to a low of 30 96 feet below MSL at <br /> MW-8A <br /> Separate groundwater surface maps are included for the shallow-constructed wells (Figure 4) <br /> and the deep-constructed wells (Figure 5) Using the shallow-constructed wells, the <br /> groundwater surface appears as an irregular plane dipping toward the northeast at a gradient of <br /> 0 00249 foot/foot Using the deep-constructed wells, the groundwater surface appears as an <br /> irregular plane dipping toward the northeast at a gradient of 0 00302 foot/foot The groundwater <br /> surface configurations are generally consistent with historical groundwater gradients and flow <br /> directions <br /> 22 Groundwater Sampling and Analysis <br /> Groundwater was sampled from seven monitoring wells (MW-2, MW-3, MW-4, MW-5, MW-6, <br /> MW-7, and MW-813), two deep sod vapor extraction wells (VW-1 and VW-2), and Irrigation Well <br /> #2 Each of the monitoring wells and deep sod vapor extraction wells was purged of at least <br /> three well volumes using a pump and disposable tubing Following purging and recharge, <br /> groundwater samples were collected from the wells using dedicated and disposable sampling <br /> bailers Irrigation Well #2 was allowed to flow at the wellhead until the downhole pump was <br /> automatically activated A groundwater sample was collected directly at the wellhead through a <br /> sample port <br /> I is 5 <br />
