| Description |
Limited sampling for insecticides in Yellowhawk, Lower Mud, Dry and Pine Creeks in April and May 1997 showed no evidence of water quality concerns due to diazinon, malathion, aldrin, or DDT, identified through a survey the previous year. Trace levels (0.002 - 0.017 ug/L; ppb) of diazinon, azinphos, methyl parathion, and dimethoate were found in the 1997 samples. Extremely high concentrations of total suspended solids were observed in Yellowhawk, Dry, and Pine Creeks. |
