Certain source areas known as "pollution hot spots" have a higher chance to create contaminated surface level runoff due to given activities occurring and associated contaminant types present on site (i.e. vehicle fueling stations, landfills, certain agricultural practices, manufacturing and construction sites, etc. As a result of this different runoff contamination levels also limit the types of treatment opportunities and practices that can be implemented in varying source water areas. It is important that stormwater management plans be developed with consideration of the different types of runoff source areas that will be present, and recognition of source

areas with low to moderate contamination potential that represent opportunities for [[Rainwater Harvesting]], [[permeable pavements]] and other stormwater infiltration practices. Furthermore, it is vital to ensure that relatively clean runoff is not mixed with lesser quality runoff from surfaces that are subject to higher levels of contamination, rendering it less suitable for infiltration or harvesting.
