Stormwater-NPDES monitoring program at the Rocky Flats Plant, near Denver, Colorado

摘要

This paper highlights results of this stormwater NPDES permit-application monitoring program (ASI, 1991b; 1992; 1993). Over a 15-month monitoring period, 32 events were sampled at various surface-water and/or bulk-precipitation sites included in the monitoring network. Evaluation has been made of the effectiveness of obtaining comprehensive hydrograph coverage for a number of storm-runoff/high-flow events as well as in obtaining data over a range of hydrologic conditions and time of year. Examples of event-sample coverage are provided, as well as an assessment of resultant event-generated water-quality data. During the 15-month monitoring period, a total of 116 storm-runoff /high-flow samples (32 events) and 19 bulk-precipitation samples were collected.
