About Neighborhood Health Hazard Investigations

Many types of facilities can pollute the air we breathe, water we depend on, and land around us. That pollution can have a big impact on the lives of people who live, work, play, and learn nearby. The impact can be anything from a mild headache to lifelong learning difficulties to contaminated groundwater that may put us at risk during future droughts.

Select a topic below for information regarding specific environmental incidents and to learn about reducing your exposure to environmental hazards.

Learn to report problems as soon as you see, hear, or smell them in and around your community by visiting our How to Report page. There are laws to control how much businesses can pollute the area and your input helps keep the community safe and healthy.
