A suite <br />which includes major cations, major anions, pH, conductivity, cyanide, and all major <br />trace metals is $280.50/sample.

A list of all the wells and lysimeters to be abandoned is presented in <br />Table L-1. An estimate of the cost of abandoning the wells was obtained from <br />Irrigation Engineering in Alamosa, Colorado. The costs are as follows: <br />Removing pump = $300 per well. <br />Well abandonment = $400 per well. <br />Since none of the wells that aze to be abandoned have pumps, the total cost of <br />abandoning the wells and lysimeter is estimated to be $22,000. <br />L.5 Seeding Cost <br />Remaining areas requiring seeding per 2005 reclamation summary include: <br />1. Tailings surface = 22.6 acres. <br />2. Tailings collection pond = 5.0 acres. <br />Battle Mountain Resoarces, /nc.
