Mercury Minimization

Greenville Utilities is committed to protecting our community and environment through our Mercury Minimization Program. This initiative educates residential customers about the safe disposal of products that may contain mercury, helping prevent harmful releases into our water, air, and soil. GUC’s Industrial Pretreatment Program also addresses mercury-related disposals for our industrial customers. 

Why Mercury Minimization Matters

Mercury (Hg) is a naturally occurring element used in many household and industrial products. If handled improperly, even small amounts can be hazardous to humans and wildlife. Mercury is bioaccumulative, meaning it builds up in the food chain, with the highest concentrations found in predatory fish and shellfish as methylmercury, the most toxic form.  

In North Carolina, largemouth bass and bowfin often show elevated levels, especially in areas with high mercury methylation rates. Exposure to methylmercury can cause serious health effects, so minimizing mercury in our environment is essential.

The Environmental Protection Agency (EPA) and Food and Drug Administration (FDA) determine safe mercury limits by evaluating “reference doses” (RfD) and setting actionable advice for seafood consumption.
