Water is essential to life. The drinking water we receive comes from ground water, streams, lakes, and springs. Therefore, protecting source water from contamination and treating drinking water to eliminate germs are both crucial to providing safe water for the public.
When it comes to water, public health concerns include pollution prevention, water quality testing, waterborne disease prevention and fluoridation of drinking water to prevent cavities. Contaminated water can expose people to waterborne pathogens including cryptosporidium and giardia.
