	abstract = {The promulgation of the 1990 National Pollutant Discharge Elimination System (NPDES) Permit Application Requirements for Stormwater Discharges effectively prohibits non-stormwater discharges to municipal separate storm sewer systems. In an effort to achieve results in a cost effective manner, while placing high priority on pollution prevention activities, the EPA recognized the need for simple screening methods which would allow problem storm outfalls to be identified. A sampling scheme for outfall dry-weather flow, coupled with chemical testing and visual observation, was proposed. Very little field verification work had been completed when the EPA drafted, and subsequently adopted, the 1990 stormwater regulations, which established the minimum screening protocol to be carried out by municipalities. No information regarding appropriate analytical test methods or interpretation of results accompanied the regulations. This research addressed these deficiencies by testing appropriate analytical methods, while developing and testing a screening methodology for identifying storm sewer outfalls contaminated by inappropriate discharges in residential and commercial land use areas. Test parameters proposed by EPA were examined, along with additional parameters which seemed promising for work in residential and commercial areas. Interpretive methods were developed and tested, which allow results from outfall screenings to be interpreted at the local and state levels. The results of this investigation indicated that EPA{\textquoteright}s minimum testing requirements were sufficient to allow outfalls to be categorized as contaminated or uncontaminated, based on detergent measurements alone. Additional testing for fluoride, ammonia and potassium allowed the most contaminating source type contributing flow to an outfall to be correctly identified. Potential source types were grouped into four categories which were ranked from highest to lowest, based on potential for contamination, as follows: Sanitary wastewater sources, wash water sources, tap water sources, and natural water sources.},
