Encourage Proper Use of Fertilizers

Over fertilization is negatively affecting surface and ground waters in Idaho. Fertilizer contributes nitrates, phosphorus, sulfur, magnesium, and more to our drinking water supplies. It may also indicate the presence of other harmful chemicals, such as pesticides and herbicides.

Encourage your drinking water customers to be conservative with home use of fertilizers. People often over apply fertilizer on their lawns, and over water! Explaining how fertilizer can move over paved surfaces and also leach through soils into groundwater can help people make the connection between their actions and the health of their aquifer. Provide education regarding drinking water treatment and the increase in utility bills associated with treatment.
