laboratory which is acceptable to the BLM and EPA. Custody record sheets <br />will be maintained.The: potentiometric water level in the wells will be recorded <br />continuously using'a pressure transducer type recording device and solar <br />powered data storage unit. Quarterly manual readings will be obtained to verify <br />pressure transducer data. The data from water level devices will be retained by <br />WRN and will be summarized within the hydrology monitoring reports <br />submitted to the BLM and EPA. <br />1.42 Well Field Monitor Wells <br />Well field wells will be monitored at the same frequency and methodology as <br />the dedicated wells. Special wells 4-1V, 91-2M and 94-1M will be monitored <br />only for continuous Dissolution Surface water level. <br />Section II -Surface Water Monitoring Plan <br />1.0 Seeps and Springs <br />All seeps and springs located within the projected cone of depression of the water <br />supply well are to be inventoried and monitored per the BLM ROD. In compliance <br />with this stipulation, Wright Water Engineers was engaged to project the extent of <br />the cone of depression resulting from pumping the water supply well. The basis <br />for the modeling and projection of the cone of depression was nearly four times the <br />actual average pumpinl; rate through 1996. The cone of depression was projected <br />to extend to Ryan Gulch, but not to location of any know springs in the gulch or <br />springs elsewhere. In addition, WRN conducted field and literature surveys to <br />detemvne whether any springs or seeps existed within the cone of depression. No <br />springs or seeps exist within the cone of depression, and consequently, no <br />monitoring plan for seeps and springs was required. <br />26 <br />
