Nonpoint Source Pollution (NPS) … What Is It?

By Mary Beth McCaughey, Vice President, FBMG S2000

 

As we enter the season of active gardening and regular outdoor activities, I thought it would be good to remind folks that our individual actions have an impact on the world around us:

 

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 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 residential areas and agricultural lands;

· Oil, grease, and toxic chemicals from urban runoff;

· Sediment from improperly managed construction sites, crop and forest lands, and eroding streambanks;

· Bacteria and nutrients from livestock, pet wastes, and faulty septic systems.

 

Q: What are the effects of these pollutants on our water?

 

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 NPS?

 

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 NPS?

 

A:We can all help to reduce and prevent NPS. Governments have some responsibility but individuals have a role also. We can each practice conservation, take care with the types of chemicals used in and around our homes pick up pet wastes, and make sure that litter is disposed of responsibly. Give a bit of thought to everyday habits—the world will be better for it
