Learn, Correct, Keep it Clear
Protect your water—it’s just beneath your feet.
Pollutants that go down our storm drains could end up in our water. These contaminants also have the potential to harm local wildlife in nearby waterways.
Watch the video and click each culprit below to learn about common pollution issues and how you can prevent further impact to our groundwater.
Learn About Common Pollution Culprits
Trash & Litter
The number one pollutant in our stormwater collection system, litter causes many problems for our groundwater. It can clog the basins, which reduces the infiltration and replenishment of rainwater into the groundwater. The solution is simple: don’t litter!
How can I help?
Properly dispose of your trash by following city guidelines regarding cans and pick-up days. You can also volunteer to clean trash. See the Clean-Up schedules in Fresno, in Clovis, and in the County.
Motor Oil
Motor oil is one of the hardest contaminants to remove from our water, so it should never be dumped down storm drains. When you change the oil in your car, runoff can go into the gutter and enter the stormwater collection system.
How can I help?
Paint & Paint Thinner
Paints and paint thinners become serious offenders of groundwater pollution when they are dumped on the ground or into storm drains. When cleaning after a home renovation project, toxins can enter the stormwater collection system and pollute the water supply.
How can I help?
Pool Draining
Most pools do not need to be drained often. But even regular maintenance, such as cleaning the filter, can cause pollution to enter the storm drains if not done properly. When pool water is drained into or near a storm drain, chlorine and other chemicals can enter the groundwater.
How can I help?
Sewage
Before dumping sewage, which includes RV waste, wastewater, commercial kitchen oil, or any cleaning solution, you have to find the right place to do so! Sewage is harmful to the environment and should never go down the storm drain because it can contaminate our groundwater.
How can I help?
Fertilizer & Pesticides
If you fertilize or use pesticides in your yard, you may be polluting the groundwater. Inadvertent overwatering leads to chemical contaminants flowing into the storm drains. Nitrates from fertilizers and toxins from pesticides are soluble pollutants that can quickly reach our groundwater.
