Pesticides
Are you storing leftover pesticides? Clean out leftover pesticides (such as those containing chlorpyrifos, diazinon or pyrethroids) and other chemicals by safely disposing of them through your local household hazardous waste facility. Also, consider using a non-toxic or less toxic pesticide alternative.

Salinity
Salinity is the presence of dissolved mineral salts in water. Elevated salinity in surface water and groundwater is an increasing problem affecting California’s Central Valley. While some salt is beneficial, too much salt can degrade water quality, jeopardize agricultural production and increase the cost of our water supplies. Stakeholders throughout the Central Valley are working together to ensure that excess salts do not contaminate our precious water and soil, but we need your help.
Per- and Polyfluoroalkyl Substances (PFAS)
Issue
Per- and polyfluoroalkyl substances (PFAS) have been detected in some water resources throughout the country, especially in groundwater drinking wells near airports, military bases, and manufacturing sites. Perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) are two of the more prominently found PFAS constituents and are no longer manufactured or imported into the United States; however, there could be some imported goods containing trace amounts of these substances.
