i~ .r ~ ~:_ % -- - November 15, 1999 Routt County Planning Attention: Caryn Fox P.O. Box 773749 Steamboat Springs, CO 80477 Deaz Ms. Fox, h.,i ~ ,.;oli ~ ,~^ i u L ~ + "' Enclosed aze copies of the water quality analyses for samples collected last August from the Tellier and Anderson residence wells, and last May from the monitoring well neaz the Tellier Pit. [have compazed the analyses with national drinking water standazds in Table 1 through Table 3 (see attachments). All of the tested parameters met drinking water standazds and were significantly below levels that aze considered to present human health risks. Table 4 in the enclosed attachments is a summary of the Tellier Pit sand and gravel mining activities with their associated potential pollutants, potential impact on surface and ground water, and analytes that should be tested to identify the pollutants. Based on the activity at the Tellier Pit, Connell Resources recommends that our annual ;round water testing be limited to pH, Total Dissolved Solids (TDS), Oil and Grease, Extractable Total Hydrocazbons, and BTEX (benzene, toluene. ethylbenzene, and xylenes). The EPA recommends that ground water drinking supply wells should be annually tested for colifotm bacteria and nitrates. These potential pollutants aze most likely related to septic systems and fertilizers. Although Connell Resources activities at the Tellier Pit will not contribute coliform bacteria or nitrates to the ground water system, we will conduct these tests as a gesture of goodwill. If there are any questions or additional information needed please contact Tony or myself at 870- 0200. Sincerely, Arthur M. Morrissey v Compliance Officer CONNELL~ESOURCES, INC.
