Once installed, all new wells shall be <br /> added to the MRP and shall be sampled and analyzed according to the schedule below. <br /> Prior to sampling or purging, equilibrated groundwater elevations shall be measured to the nearest 0.01 <br /> foot. Depth to groundwater measurements shall be collected from all wells on the same day. The wells <br /> shall be purged at least three well volumes until pH and electrical conductivity have stabilized. Sample <br /> collection shall follow standard EPA analytical method protocols. Groundwater monitoring shall <br /> include, at a minimum, the following: <br /> Sampling Reporting <br /> Constituent Units Type of Sample Frequency Frequency <br /> Depth to Groundwater 0.01 ft,_ Measurement Quarterly Quarterly <br /> Groundwater Elevation 0.01 ft Calculated Quarterly Quarterly <br /> Gradient ft/ft Calculated Quarterly Quarterly <br /> Gradient Direction Degrees Calculated Quarterly Quarterly <br /> pH S.U.

The data shall be summarized in such a manner to clearly illustrate compliance with waste <br /> discharge requirements and spatial or temporal trends, as applicable. The results of any monitoring done <br />
