Top Ten Water Pollution Facts

Below are a few water pollution facts that all clean water lovers should know (and share with their friends)!

#1: When it rains water runs directly into L.A.’s storm drains where the water flows into our local waterways and then the ocean. This stormwater is much different than sewer water, as it is not connected to a treatment facility before entering our ocean.

#2: Small amounts of contaminants like pesticides and herbicides on our grasses and in our gardens can end up causing water pollution. When it rains, or when you run your hose, the water can carry these pollutants into the street where it enters the stormwater system.

#3: Excess lawn grass and yard waste after mowing or trimming can put unwanted fertilizer in our streams. This waste can cause pollution problems where it is discharged by using up oxygen in the water, which can then kill fish and other plants.

#4: Soil runoff can cause water pollution. Erosion from landscaping or dirt piles can run into the storm drain system which can greatly impact water quality.

#5: Rain barrels that are connected to downspouts can greatly reduce the amount of runoff from our properties that could contribute to stormwater pollution. These barrels catch the water before it has a chance to run over our lawns and into the street. And a little added bonus, this water can be reused for basic lawn and garden watering, saving you a few extra bucks!

#6: Oil and antifreeze that leaks from our cars can cause major water pollution problems. When water runs over the ground it can pick up these substances where they then enter the storm drain. Every little bit this water picks up can have a cumulative impact on water quality at our local beaches.

#7: Pet waste pollutes. When we don’t pick up after our pets outdoors their waste can enter the storm drain system, causing our the water quality to decrease. Check out our pet page for more information (and find out how to get a FREE container of doggie waste bags)!

#8: Household cleaners, when dumped outside, can pollute. Always properly dispose of household cleaners and chemicals.

#9: Sewage from boating in our oceans and bays can pollute. Untreated sewage from boating vessels is a significant risk to human health and ocean life.

#10: Litter. Every piece that ends up on our streets and sidewalks can cause major pollution problems for our ocean. When it rains this trash can make its way to the beaches. Plastics stay around for hundreds of years, and can kill wildlife.

So remember, let’s all do our part to reduce unwanted pollutants from entering our stormwater system. For more information please visit our LA Stormwater website.
