Stormwater runoff is precipitation from rain or snowmelt that flows over the ground, parking lots and streets. Stormwater can pick up debris, vegetation, chemicals, dirt, grass clippings, leaves and other pollutants. These pollutants flow directly into the local storm drain system or water body.

Anything that enters a storm drain system is discharged, untreated, into the waterbodies we use for swimming, fishing, and providing drinking water. In Merced, these waters drain directly into Bear Creek, Black Rascal Creek, and other natural waterways.

Chlorinated water discharged to surface waters has an adverse effect on local water quality. Swimming pools are a major source of chlorinated water discharged into sanitary and storm sewer systems. An average swimming pool holds 19,000 gallons of highly chlorinated water, which is toxic to wildlife and fish. Dechlorinated swimming pool water discharged to the Publicly Owned Treatment Works (POTW) must have a pH value in the range of six (6) to ten (10) standard units.


Remember: Only Rain Down the Drain
