Cleaning Up Contamination

Historical and accidental spills, leaks, and instances of improper disposal and handling of pollutants have resulted in contaminated land, water, and air across our state. Contamination must be assessed and either cleaned up or effectively managed to eliminate or prevent risk to human health or further degradation to the environment.

The Office of Land Quality (OLQ) oversees investigation and cleanup actions at sites where contaminants have or may have been released. OLQ employs a variety of investigation and cleanup programs in partnership with other state agencies, municipalities, federal agencies, or responsible parties to investigate, assess, manage, and/or clean up contaminated properties.

These actions can lead to beneficial site reuse and redevelopment. Learn more about how OLQ handles cleanups and how cleanups affect you.
