Storm Water pollution
n Storm water pollution refers to many types of harmful materials that are carried by water (rain water or wash water) through the storm drain system to creeks, lakes, rivers and ultimately to the ocean.
n Storm water is not treated in any way.

n Storm water is not treated in any way. n Storm water pollution has many
sources. n One of the most common is the illegal
dumping or spilling of wastes directly into storm drains, like pouring used motor oil or paint directly into a storm drain.

Fertilizer
Limiting fertilizer use will avoid nutrient overload in streams.
· Plant vegetation native to our area. These are suited to the soil type, slope,

These are suited to the soil type, slope, available sunlight, and climate.
· Prior to fertilizing, test soil to determine what nutrients soil may need.
· Mow lawn 1/3 of the total grass height only, mow when dry- with sharp mower blades, and leave the clippings on the lawn.
· During summer months, cut grass higher to help retain soil moisture.
Erosion
Sediment (clay, silt) is the #1 source of water pollution. Bare soil easily washes into storm drains and streams, clouding the water and suffocating aquatic life.

• Never leave soil exposed! Place straw over newly seeded areas.
• Cover your garden during winter months.
• Sod, seed, grow plants, or build terraces on slopes.
• Rock gardens can also be effective for slowing the flow of water and minimizing erosion.
Pest Management
If a bug is killed in the lawn by pest, it may kill fish in the stream also. Use pesticides sparingly by practicing “integrated pest management.”

Yard Trimmings
Yard trimmings should not be put in a stream. Instead, compost trimmings or take them to a local composting program.

composting program.• Chop or shred waste into small
pieces.• Add equal amounts of a carbon
source (dried material) to a nitrogen source (green plant material).
• Turn the pile regularly and maintain slight moisture.
Pets

Scientists believe that fecal matter from pets is a major source of bacteria in urban waterways.
• Flush fecal material down the toilet or wrap it up and place it in the trash.
• Restrict pets from streamside area. • Control fleas with minimal pesticide use.
Driveway
Reduce contaminant run-off from your driveway!
• Do not wash oils or other spills down the

• Do not wash oils or other spills down the storm drain!
• Wash your car at a designated car wash or (at least) wash with a low-phosphate soap in an area where the water will soak into the ground.
NEW CONSTRUCTION:Use bricks with sand, stones, or paving
blocks instead of impermeable pavement.
Streamside
Streams should be kept healthy. Control run-off contamination.
11
Control run-off contamination.• Landscape yard to provide areas
where water will soak into the ground.
• Leave 25’ buffer strips of thick, native vegetation along streams.
• Pick up litter.• Monitor your stream for pollutants
and help to determine the source.
Recycling and Waste Disposal
Do not allow wastes to enter into a storm drain or stream.

a storm drain or stream. Contamination can injure or kill fish and wildlife.
• Do not burn or bury trash.
• Reuse and recycle everything possible.
House Hazardous Wastes
Household Hazardous Wastes (HHW), especially auto fluids, are a common contaminant found in waterways. Never pour products on the ground or down a

pour products on the ground or down a storm drain.
• Have your vehicle serviced at a garage where fluids will be recycled or properly disposed.
• If doing it yourself, recycle auto fluids, oil filters, batteries, and tires.
HHW(Cont.)
Other examples of HHWs include: Paint products/ fuels/ solvents/ pesticides/ and mercury-containing products. Here’s what you can do:
14
you can do:-1st REDUCE: Buy the least hazardous
and only the quantity that you will use.
-2nd REUSE: Give it to someone to use for its intended purpose.
-3rd RECYCLE leftover products whenever possible.
REDUCE, REUSE and RECYCLE is the most important mantra of present day for
