The operator shall record which seepage pits or leachfields are receiving wastewater. Evidence <br /> of surfacing wastewater, poorly draining seepage pits, field saturation, runoff, or the presence of <br /> nuisance conditions shall be noted in the report. If surfacing wastewater or poorly draining leachfields <br /> are observed, the condition shall be noted and the need for system repair evaluated. <br /> GROUNDWATER MONITORING <br /> Beginning with the first quarter of 2004, the Discharger shall conduct the following groundwater <br /> monitoring program. Prior to construction of any groundwater monitoring wells, the Discharger shall <br /> submit plans and specifications to the Board for review and approval. Once installed, all new wells <br /> shall be added to the MRP, and shall be sampled and analyzed according to the schedule below. <br /> Prior to sampling, groundwater elevations shall be measured and the wells shall be purged at least three <br /> well volumes until pH and electrical conductivity have stabilized. Depth to groundwater shall be <br /> measured to the nearest 0.01 feet. Water table elevations shall be calculated. Samples shall be <br /> collected using approved EPA methods. Groundwater monitoring shall include, at a minimum, the <br /> following: <br /> Type of Sampling and Reporting <br /> Constituent Units Sample Fre uenc <br /> Groundwater Elevation' 0.01 Feet Measurement Quarterly <br /> Depth to Groundwater 0.01 Feet Calculated Quarterly <br /> Gradient Feet/Feet Calculated Quarterly <br /> Gradient Direction degrees Calculated Quarterly <br /> PH S.U.
