Questions and Answers (Taken from EPA's Polluted brochure EPA-841-F-94-005, 1994)
Q: What is nonpoint source pollution?
A: Nonpoint source (NPS) pollution, unlike pollution from industrial and sewage treatment plants, comes from many diffuse sources. NPS pollution is caused by rainfall or snowmelt moving over and through the ground. As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into lakes, rivers, wetlands, coastal waters, and even our underground sources of drinking water. These pollutants include: Excess fertilizers, herbicides, and insecticides from agricultural lands and residential areas; Oil, grease, and toxic chemicals from urban runoff and energy production; Sediment from improperly managed construction sites, crop and forest lands, and eroding streambanks; Salt from irrigation practices and acid drainage from abandoned mines; Bacteria and nutrients from livestock, pet wastes, and faulty septic systems; Atmospheric deposition and hydromodification are also sources of nonpoint source pollution.
Q: What are the effects of these pollutants on our waters?
A: States report that nonpoint source pollution is the leading remaining cause of water quality problems. The effects of nonpoint source pollutants on specific waters vary and may not always be fully assessed. However, we know that these pollutants have harmful effects on drinking water supplies, recreation, fisheries, and wildlife.
Q: What causes nonpoint source pollution?
A: We all play a part. Nonpoint source pollution results from a wide variety of human activities on the land. Each of us can contribute to the problem without even realizing it.
Q: What can we do about nonpoint source pollution?
A: We can all work together to reduce and prevent nonpoint source pollution. Some activities are federal responsibilities, such as ensuring that federal lands are properly managed to reduce soil erosion. Some are state responsibilities, for example, developing legislation to govern mining and logging, and to protect groundwater. Others are best handled locally, such as by zoning or erosion control ordinances. And each individual can play an important role by practicing conservation and by changing certain everyday habits.
- Increasing infiltration/ Decreasing runoff- plant trees, raingardens, gardens, decrease impervious surfaces, decrease area of lawn taken up by grass, use native plants.
- Landscaping for water quality- Link to WMEAC Raingarden Page- www.raingardens.org "courtesy of http://www.raingardens.org/." If anyone is interested, we have books from the State of Michigan about landscaping to improve water quality.
- Stormwater- The following link has a lot of useful information about polluted runoff (non-point source pollution)- http://www.epa.gov/nps/
- Hazardous Waste- Household Hazardous Waste can be taken to the North Kent Transfer Station on 10 Mile Rd., just east of US 131. Materials are taken by appointment only on Friday mornings. Please call 616 336 4617 for more information. Or go the the Kent County Department of Public Works web site at http://www.accesskent.com/.
- Wellhead Protection Program- A Wellhead Protection area is an area where the wellheads of the residents need to be protected and the well may be at risk. The wellhead protection area in Cannon Township is located in sections 5 and 6; more specifically between 10-Mile Road and 9-Mile Road on the North and South, respectively, and Wolverine Boulevard and Myers Lake Avenue on the East and West.If you live in this area, you should be concerned because this means that your well water is more easily susceptible to contaminants introduced into the groundwater, which is where all the water in your home comes from.
