Regional Stormwater Monitoring Program - 1st Permit Term

Participants


Cities of Dallas, Fort Worth, Arlington, Irving, Plano, Garland, and Mesquite, and two transportation agencies—Texas Department of Transportation-Dallas District and North Texas Tollway Authority


Sampling Details


A network of 30 monitoring sites was negotiated with EPA Region 6. The 30 sites represented single, predominant area land uses. From 1992 through 1994, 210 storm events were sampled for 188 constituents. The data were used for the NPDES stormwater permit application process. The initial data were analyzed for improving the program and finding cost effectiveness.


The resulting analysis determined that several sites could be discontinued and several of the 188 constituents were never detected and could therefore be dropped from the monitoring list. The regional program went forward with a new set of parameters and monitoring locations. From 1997 through 2001, over 330 samples were collected from a 22 site network for 33 constituents.
