MON-42

"This is a sample of the top discharge of three deep mine discharges that emanate from a hillside and enter the killer tributary just upstream from the mouth on the east side of 104th Cavalry Road. This discharge is usually dry, but seems to flow very heavily during periods of heavy rain, possibly only after the mine complex fills up beyond where MON 40 and MON 41 discharge. The following loading values are based on only 4 months of data, as this is the number of times this discharge was flowing over the study period. Average flow is 380 gpm, and the average pH was 3.4. This discharge is net acid. On average, it contributes 470 lbs/day of acid, 13 lbs/day of iron, 83 lbs/day of manganese, and 58 lbs/day of aluminum. Additional data for this point was collected in association with the Sky Haven Coal “Otto #1” surface mining operation (4574SM33, MP 13)."
