The groundwater monitoring program for these wells and any treatment system <br /> wells installed subsequent to the issuance of this MRP, shall follow the schedule below. Monitor wells <br /> with free phase petroleum product or visible sheen shall be monitored, at a minimum, for product <br /> thickness and depth to water. The volume of extracted groundwater, if applicable, shall also be provided <br /> in quarterly monitoring reports. Sample collection and analysis shall follow standard EPA protocol. <br /> The monitor wells, extraction wells and/or injection wells shall be sampled according to the schedule in <br /> Table I and the samples analyzed by the methods in Table 2, as follows: <br /> Table 1 : Sampling Frequency and Constituent Suite <br /> Well Number' Fre uenc Constituent Suite(s s Monitoring Objective <br /> Compliance' <br /> Treatment Zones <br /> Transition Zone <br /> Back round <br />
