11 Steps to Reduce Non Point Source Pollution

What Is NPS

Non point source pollution (NPS) is water contamination that arises from numerous indirect sources instead of a solitary point. This makes it troublesome to follow and control.

NPS can emerge from various distinct wellsprings, for example:


Suburban Stormwater Discharge


And Forestry

Given the multifaceted nature of this issue, lessening nonpoint source pollution requires engagement from various sectors of society. If we are to decrease NPS, it is critical to comprehend what it is and where it originates from initially.

NPS Causes

Numerous substances can bring about NPS, for example, oil, pesticides, chemicals, sediment, and nutrients.

These contaminants can cause a scope of ecological issues, including water system blockage, fish kills, and contamination of drinking water supplies.

NPS can likewise have human well-being impacts, for example, skin rashes, gastrointestinal sicknesses, and cancer.

Non Point Source Pollution Examples

There are many different types of NPS pollution, but some of the most common include:

Agricultural runoff

This is water that flows off of farm fields and into waterways, and it can contain pesticides, herbicides, fertilizers, and other dangerous chemicals.

Urban runoff

This occurs when rainwater washes over hard surfaces like pavement and concrete. It picks up oil, grease, pesticides, and other pollutants before flowing into storm drains and eventually waterways.

Construction site runoff

When construction sites are not adequately managed, rainwater can wash away dirt, rocks, and other materials. This can pollute nearby waterways with sediment (dirt) and chemicals.

Reduce Nonpoint Source Pollution

Now that we know what NPS pollution is let’s talk about how we can reduce it.

Here are 11 steps you can take to help make a difference:

Use less water

This may seem obvious, but using less water will reduce the amount of runoff. Try to water your lawn only when necessary, and use a hose with a shut-off nozzle to avoid wasting water.

Sweep up debris

Whenever you’re doing yard work, be sure to sweep up any debris that could blow into a storm drain. This includes leaves, twigs, and grass clippings.

Pick up after your pet

Animal waste can contain harmful bacteria and viruses that can pollute waterways. So please pick up after your pet whenever they go to the bathroom outside.

Dispose of chemicals properly

Never pour hazardous chemicals down the drain or in storm drains, and always dispose of them at a local household hazardous waste facility.

Fertilize wisely

When fertilizing your lawn or garden, use only as much as necessary and avoid applying it before a rainstorm. This will help reduce the amount of runoff.

Use natural alternatives

Whenever possible, use natural alternatives to harmful chemicals. For example, vinegar can be used as a weed killer, and baking soda can be used as an antacid.

Cover your trash

Ensure all of your trash cans have tight-fitting lids to keep animals from getting in and spreading garbage around. And when disposing of large items, cover them with a tarp to prevent them from blowing away.

Plant trees and shrubs

Trees and shrubs can help absorb rainfall and prevent runoff. They can also provide homes for wildlife and beautify your community.


Many organizations work to reduce non point source pollution. Volunteer your time to help them with their efforts.

Spread the word

Educate your family and friends about NPS pollution and what they can do to reduce it.
