What can you do to
Help Protect S
urface and Ground Waters
from Nonpoint Source Pollution?

You can start at home.

Begin by taking a close look at practices around your house that might be contributing to polluted runoff. You might find that you need to make some changes.

The following are some specific tips to act on—dos and don'ts, organized by categories, to help you become part of the solution rather than part of the problem of nonpoint source pollution.

In Your House

Household Chemicals 

Be aware that many chemicals commonly used around the home are toxic. Select less-toxic alternatives. Use non-toxic substitutes wherever possible.

Buy chemicals only in the amount you expect to use, and apply them only as directed. More is not better.

Take unwanted household chemicals to hazardous-waste collection centers; do not pour them down the drain. Pouring chemicals down the drain could disrupt your septic system or contaminate treatment plant sludge. 

Never pour unwanted chemicals on the ground. Soil cannot purify most chemicals, and they could eventually contaminate runoff. 

Use low-phosphate or phosphate-free detergents.

Use water-based products whenever possible. 

Leftover household pesticide? Do not indiscriminately spray pesticides, either indoors or outdoors, where a pest problem has not been identified. Dispose of excess pesticides at hazardous-waste collection centers.

On Your Property

Gardening and Landscaping 

Cultivate plants that discourage pests.

Minimize grassed areas, which require high maintenance.

Preserve existing trees, and plant trees and shrubs to help prevent erosion and promote infiltration of water into the soil. 

Use landscaping techniques, such as grass swales (low areas in the lawn) or porous walkways, to increase infiltration and decrease runoff.

Other landscaping tips:

Install wood decking, bricks or interlocking stones instead of impervious cement walkways.

Install gravel trenches along driveways or patios to collect water and allow it to filter into the ground. 

Restore bare patches in your lawn as soon as possible to avoid erosion. 

Grade all areas away from your house at a slope of one percent or more.

Leave lawn clippings on your lawn so that nutrients in the clippings are recycled and less yard waste goes to landfills.

If you elect to use a professional lawn care service, select a company that employs trained technicians and follows practices designed to minimize the use of fertilizers and pesticides.

Compost your yard trimmings. Compost is a valuable soil conditioner that gradually releases nutrients to your lawn and garden. (Using compost will also decrease the amount of fertilizer you need to apply.) In addition, compost retains moisture in the soil and thus helps you conserve water.

Spread mulch on bare ground to help prevent erosion and runoff.

Test your soil before applying fertilizers. Over-fertilization is a common problem, and the excess can leach into ground water or contaminate rivers or lakes. Also, avoid using fertilizers near surface waters. Use slow-release fertilizers on areas where the potential for water contamination is high, such as sandy soils, steep slopes, compacted soils and verges of water bodies. Select the proper season to apply fertilizers—incorrect timing could encourage weeds or stress grasses. Do not apply pesticides or fertilizers before or during rain because of the strong likelihood of runoff.

Calibrate your applicator before applying pesticides or fertilizers. As equipment ages, annual adjustments might be needed.

Keep storm gutters and drains clean of leaves and yard trimmings. (Decomposing vegetative matter leaches nutrients and can clog storm systems and result in flooding.)

In the Winter Months

Choosing a Deicer - All deicers impact the environment. Below are some tips to minimize the impact.

A deicer is a product that melts snow and ice and is used to break the bond between snow and ice and the pavement. Rock salt is another name for sodium chloride. It is a common deicer that is inexpensive, but it does not melt effectively in low temperatures.

The best time to apply a deicer is right after a storm and after shoveling. Let the deicer work to break the bond between the snow and pavement and then shovel again.
Don't mix salt and sand together. Sand only provides traction when it is on top of snow and ice. Salt will melt the sand into the snow and ice making it ineffective.

Follow these steps to help protect the health of our waters:

The more snow that you can shovel or snow blow, the less salt you will need. Get out early and keep up with the storm.

Ice_Melt Use the Right Deicer
Check the ingredients. Magnesium and calcium chloride work better in colder temperatures. Blends typically consist mostly of sodium chloride because it is inexpensive. Urea may be listed as pet or plant friendly, but is a poor melter.

Don't over apply the salt. More salt does not mean more melting. Use less than four pounds of salt per 1,000 square feet. One pound of salt is about a heaping twelve-ounce coffee cup.

Thermometer_littleTemperature Matters
Common deicers don’t melt snow and ice well when its very cold, so should not be applied. Instead, use a small amount of sand for traction. The temperature listed on the bag may not be the lowest temperature at which the product will melt snow or ice effectively.

Melting temperatures are generally as follows:

Sodium Chloride            15 degrees F
Magnesium Chloride        5 degrees F
Calcium Chloride          -20 degrees F

 BroomSweep Up the Extra
Salt and sand on dry pavement is not doing any work and will be washed into area lakes and creeks. So, sweep up the extra and reuse it.
