Learn more about the DEQ Mercury Initiative. Mercury is a naturally occurring element that is found in several forms. It is important to understand that short-term or long-term exposures to metallic mercury can lead to serious health problems. Be aware that mercury exposure can cause harm before symptoms arise. At high levels, mercury may cause effects on the nervous system, the developing fetus and can damage other organs. DEQ, DHH and DWF issues advisories throughout the year for fish consumption. Also, mishandling spill clean up and improper disposal of common goods containing mercury often results in mercury being found in landfills and municipal wastewater.

DEQ encourages public participation by allowing citizens to suggest BEP ideas for future consideration. Proposed BEP ideas are subject to review by the agency and must meet the requirements of the BEP requirements.
