About Local Environmental Issues

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.
