Non-point source (NPS) pollution likely represents the dominant portion of all pollution entering many estuaries, lakes, rivers, and streams in British Columbia. Unlike point source pollution, it is usually difficult to trace NPS pollution to its origin at specific sites although it is not difficult to attribute it to general sources (e.g., agricultural runoff, urban stormwater, septic tanks). This makes it difficult to regulate. Potential impacts from NPS include shellfish closures, drinking water contamination, human health effects, and degradation of aquatic habitats and their associated biota. There is now an effort by the Province to better understand the problem and raise its profile. This report is the third in a series that targets the issue of NPS pollution in British Columbia. Norocol, Dames and Moore (1995) defined the nature and extent of NPS pollution in the province. KMPG (1995) studied the issues and options for NPS pollution management. This report examines the problem in detail. It clearly do
