Objective:

Discharges from storm drainage outfalls are usually a combination of dry-weather base flows, stormwater runoff, snowmelt water, intermittent discharges of debris, wash-waters, and other waste materials into storm drains, and the relatively continuous discharges of sanitary and industrial cross--connected wastes. These discharges include stormwater that contains the washoff of pollutants from all land surfaces during rains, including washoff of pollutants from areas such as industrial material and waste storage areas, gas station service areas, parking lots, and other industrial and commercial areas, etc. Therefore, the quality of urban runoff can vary greatly with time (dry versus wet weather, cold versus warm weather, etc.) and location.

The discharge of sanitary and industrial wastes into storm drainage (non-stormwater discharges) can lead to serious water pollution problems. In many cases, storm drain discharges are badly polluted by stormwater alone, without the additional pollutant loadings associated with sanitary or industrial non-stormwater discharges. The addition of sanitary wastes increases the concentrations of organic solids and nutrients and increases the potential presence of pathogenic microorganisms in the runoff. Industrial wastes can be highly variable, but can substantially increase the concentrations of many filterable heavy metals in runoff, for example. In many cases, annual discharge loadings from stormwater outfalls can be greatly affected by dry-weather discharges.

The objectives of this case study are to evaluate the effectiveness of the proposed detection procedures, estimate the training and cost to municipalities for implementation, and prepare a final manual of practice for the detection of inappropriate discharges to stormwater drainage systems.

This project is being conducted for and supported by the LaDEQ.

Status: on-going.
