Ground water wells in the permit area do not <br /> penetrate the Mesaverde Formation . The depth to the aquifer <br /> is generally too deep and too costly to complete a well for <br /> domestic purposes . Wells that are completed in the permit <br /> and adjacent areas are completed in the alluvium, the Wasatch <br /> or the Ohio Conglomerate (Figure III-E-1) . See Table III-C- <br /> 3 ; Well Data, Coal Basin and Adjacent Area . <br /> Mid-Continent has established 4 wells (Exhibit <br /> IV-C-1) to monitor groundwater quality characteristics . In <br /> addition, the company tests static water levels (monthly) , <br /> checks water production rates and collects water samples (quar- <br /> terly) that have been. periodically analyzed to determine if <br /> changes have occurred during mining and coal preparation. <br /> Water from the wells is analyzed for dissolved oxygen, total <br /> alkalinity, total hardness , magnesium, conductivity, chloride, <br /> nitrate, ammonia, orthophophate, dissolved solids , cadmium, <br /> copper, iron, suspended solids, manganese, zinc, and sulfate <br /> on a quarterly sampling schedule. The results are presented <br /> in Appendix III-E-2 . <br /> In addition Mid-Continent has or will estab- <br /> lish a groundwater monitoring program to evaluate ground <br /> water changes associated with operating the refuse, sanitary <br /> landfill and rock fill operations. Ground water samples <br /> collected during this monitoring program will be submitted <br /> to the regulatory authority as required. <br /> d .
