Maintaining safe water qualityThe most common water pollutants are sediment and bacteria

Pollution Source SolutionAlternatives to chemicals

Car washing

Cooking grease

Erosion

Household hazardous waste

Lawn Care

Litter

Watering

Yard Waste

Alternatives to Chemicals• Use fewer pesticides and fertilizers• By using fewer chemicals and relying on

natural pest control measures, you help protect our surface waters by reducing the potential for chemical discharges.

Alternatives to Chemicals• Native plants• Healthy soil (compost)• Biological controls (lady bugs, worms)• Mulch• Natural pest controls (milk weed, DE)

Car washing

One gallon of liquid soap will pollute 200,000 gallons of water.

Car washing

Car washWash the car on the lawnCapture waste water“waterless” car wash

Cooking GreaseLiquified animal fats, greases and vegetable oils should not be poured into

sink drains. The grease hardens and sticks to the insides of sanitary sewer pipes.

The buildup can clog pipes, causing raw sewage to back up into homes or overflow from manholes.

Because many sanitary sewer pipelines run next to creeks, overflowing sewage often winds up in our streams and lakes.

In the past year, Charlotte-Mecklenburg Utilities reported 335 sanitary sewer overflows. Most were caused by cooking grease in pipes

Cooking GreasePour the grease or oil into a can, freeze it and throw it in the trash. Recycle the grease at one of the four full-service recycling centers.

You can also mix the grease with kitty-litter or coffee grounds and then throw it in the trash.

Remember that grease or frying oil from a turkey fryer should never be poured into a sink, storm drain or creek. The cooking oil needs to be recycled at a full-service recycling center

Erosion• Erosion is the displacement and deposition of soil

particles. In short, it's the picking up and setting down of dirt.

Erosion takes place when the soil is blown or washed off bare soil, such as a construction site. Erosion can also happen when there is more water in a creek than it was designed to hold.

Erosion

The best way to control erosion is to plant vegetation in bare soil.

Construction fences

Fence livestock out of streams

Household hazardous wasteUsed oil Antifreeze Bleach Turpentine Paint thinner Bug sprays/killers Paint Leftover pesticides and fertilizers Batteries Upholstery/rug cleaner Oven cleaners Drain openers Furniture polish

Just one gallon of oil will pollute one million gallons of water.

Household hazardous waste

Most HHW materials can be disposed of properly in Mecklenburg County by taking them to one of the four full-service recycling centers.

Lawn CareNever dump yard waste in creeks or storm drains. Blow grass clippings back into yards and off of streets and sidewalks. Bag yard waste when possible to avoid having it enter the storm drainage system. Keep storm drains clear of yard debris. Re-plant bare areas to avoid soil erosion. Adjust sprinklers so that irrigation water does not land on streets, sidewalks or driveways. Consider natural alternatives to pesticides and fertilizers. Reduce the amount of fertilizers applied by performing a soil test first. Do not use pesticides or fertilizers near creek, rivers or ponds. Avoid applying fertilizers before a large rain storm. Use native plants for landscaping. They are adapted to local conditions and therefore can require less

maintenance.

Litter

Anything that gets in the path of a rain drop becomes storm water pollution. That includes litter.

Litter

• Never throw anything down storm drains or out of car windows.

• Remember to keep truck loads covered to avoid accidental littering.

Wise Watering

When it rains, the water can land on two kinds of surfaces: pervious or impervious. Pervious surfaces allow water to soak into the ground. The other type, impervious, increases the amount of water in the drainage system and the amount of storm water pollution in our creeks and lakes.

Wise Watering

– Rain barrels to catch rain from the downspout – Sand or pebble sidewalks – Rain gardens – Directional sprinkler heads

Yard Waste

• Grass clippings, leaves• PET WASTE

• Farm animal waste

Yard Waste

• Use a compost bin to turn yard waste into a useful gardening product.

• Take yard waste to the curb or recycling center for collection.

• Pick up after pets
