Fish consumption health advisories are the result of concern over toxins. Oil, grease and gasoline from roadways, and chemicals used in homes, gardens, and yards are major sources of toxic contaminants. It interferes with enjoyment of our water resources. Here in Pima County, our dry washes become a convenient place for the illegal dumping of debris. During the next storm when water flows through that wash, the waste will be swept downstream, perhaps into your neighborhood.
Pollution prevention is the key to decreasing nonpoint source pollution.
You can begin at home with simple but important things. Water flowing over the land picks up an array of contaminants. Use household and garden chemicals only when necessary and follow the manufacturer's directions to apply the correct amounts. For more information, see Household Hazardous Waste. If you see an illegal dumpsite, call the Illegal Dumping Hotline to report it.
