Radon

The Radiation Control Program provides, free of charge, information packets containing information on different aspects of radon. We also register radon service providers (laboratories, contractors, and testing companies) that have a proven level of training.

Fluoride

Fluoride and Fluoridation

Fluoridation of drinking water is the addition or adjustment of fluoride to a drinking water supply for the purpose of preventing and controlling tooth decay.

Legionellosis

What is legionellosis?

Legionellosis is a disease caused by Legionella bacteria. Two different diseases make up legionellosis, Legionnaires' disease and Pontiac fever. Legionnaires' disease causes a serious type of pneumonia, a lung disease. Pontiac fever is a milder infection than Legionnaires' disease.

Disinfection Byproducts

Disinfection by-products (DBPs), also called trihalomethanes, are formed when chlorine and bromine interact with natural organic materials in water, such as in chlorinated drinking water. To protect drinking water from disease-causing organisms, or pathogens, water suppliers often add a disinfectant, such as chlorine, to drinking water. However, disinfection practices can be complicated because certain microbial pathogens are highly resistant to traditional disinfection practices.
