Point source pollution comes from an identifiable source, such as a factory or an industrial plant. Point source pollution is highly regulated through state and federal environmental laws. Most watershed pollution comes from non-point source pollution.<\/p>\n

\nPesticides, herbicides, fungicides, and other chemicals that farmers use for their crops or animals combine with the water that drains into the watersheds. These chemicals, in addition to animal waste, can lead to harmful bacteria polluting the water supplies.<\/p>\n
\nUrban runoff is also known as storm drain pollution. Rainwater drains from buildings, sidewalks, parking lots, lawns, and other urban areas and collects all the\u00a0contaminants\u00a0from those surfaces such as synthetic fertilizers, pesticides, grease, chemicals, animal droppings, etc. These pollutants drain into the storm drains and on to larger bodies of water without going through a treatment process first.<\/p>\n<\/a>
\nUrban development is a threat to watersheds because it changes water’s natural flow path. When areas near watersheds are developed, plants are replaced with impervious cover like roads, parking lots, sidewalks, driveways, and buildings, hindering the grounds ability to absorb stormwater. The resulting stormwater runoff actively erodes and contaminates streams and creeks when it carries the pollutants and debris it picks up as it flows.<\/p>\n
\n<\/strong>According to the United States Environmental Protection Agency,\u00a0an estimated 10 to 20 percent of onsite private waste water treatment systems malfunction each year, polluting the environment and causing public health risks. \u00a0Contaminants from septic systems include bacteria and viruses, nutrient pollutants such as nitrates, and household chemicals that may have been disposed of down the drain or toilet. Proper septic system maintenance can prevent pollution.<\/p>\n
