Prohable Hydro(opic Consequences -Chimney Rock Mine has shown no effects from activities at the site. Well W-10, installed next to the former Barren Ridge Pit and completed in the Fruitland Formation, has exhibited elevated levels of iron, manganese, and sulfate above the human health standazds (CDH, Water Quality Control Commission, 1994). In addition, elevated levels of TDS are also exhibited as Tables 3 and 4. The Fruitland Formation is generally not considered an aquifer due to the poor water quality associated with the coal seams and the low yield of the formation. Piteau and Associates determined the transmissivity of this formation as 130 g/d/ft, which is poor to fair potential for domestic well use. Additionally, the alluvium and surface waters in the area are considered better water sources. The Fruitland Formation in this area does not appear to be used as a source of groundwater for domestic, agricultural, or industrial purposes. A review of water well permits in the azea of T34N, R4W, did not reveal wells completed in this formation. Since no usage appears to be occurring from this groundwater, and the groundwater originally is considered non- potable, impacts associated with mining would appear to present little risk [o the environment. OTHER POSSIBLE IMPACTS i Flooding or streamflow appears not to have been affected in the past by operations, and since reclamation, does not appear likely. Surface and groundwater availability in the area does not appear affected and does not appear to be affect likewise in the future. Well owners in the area have apparently not had decreases in the available water, nor have the flows of Stolisteimer Creek been affected. Acid or toxic forming materials do not appear to be present, and currently adverse affects to water quality do not appear to be present in surface or groundwaters near the former mine.
