Oil in runoff from three watersheds: An update of an environmental concern
- East Tennessee State Univ., Johnson City (United States)
Levels of oil were determined in runoff from three watersheds. Included were a commercial area (mainly an urban mall), a residential area (located in a central city), and a portion of a limited-access highway (228.6 m long). Personnel arrived at each site before runoff began, and samples were taken every 15 min for the first hour and every 30 min for the next 2 h, unless runoff stopped sooner than this. Rainfall also was measured, and cross section of flow and velocity of the water also were determined. Samples were analyzed for total and recoverable grease and oil, using a separatory funnel extraction. The highest mean concentration of oil was from the residential watershed (10.2 mg/l), but the lowest loading rate (0.24 g/0.405 ha/min) also was from the residential area.
