Urban stormwater quality, event-mean concentrations, and estimates of stormwater pollutant loads, Dallas-Fort Worth area, Texas, 1992--1993
Technical Report
·
OSTI ID:321353
The quality of urban stormwater is characterized with respect of 188 properties and constituents. Event-mean concentrations and loads for three land uses (residential, industrial, commercial), and annual loads for 12 selected properties and constituents for 26 gaged basins in the Dallas-Forth Worth study area are presented. Event-mean concentrations (EMCs) were computed for each land use for biochemical oxygen demand; chemical oxygen demand; suspended and dissolved solids; total nitrogen and ammonia plus organic nitrogen; total and dissolved phosphorus; total recoverable copper, lead, and zinc; and total diazinon. The EMCs of chemical oxygen demand; total nitrogen and ammonia plus organic nitrogen; total and dissolved phosphorus; and total diazinon were greatest in samples from residential land-use basins. The EMCs of biochemical oxygen demand; suspended and dissolved solids; and total copper, lead, and zinc were greatest in samples from industrial land-use basins.
