Why Monitor Water for Mercury with KETOS

Mercury is a highly mobile and extremely toxic element that can bioaccumulate in fish, which can put humans and animals that eat them at risk.

The Clean Water Act regulates monitoring mercury in effluent, waste, and ambient waters to protect human populations and the environment. The EPA also issues mercury guidelines and national standards for wastewater discharged to municipal sewage treatment facilities and surface water. There are also specific guidelines across other industries, including electric steam utilities (coal, oil, natural gas) and their resulting waste (for example, coal ash ponds, a by-product of coal-powered plants).

The EPA, under the Safe Drinking Water Act, has set enforceable regulations for mercury at 0.002mg/L. Public water systems are under strict regulatory scrutiny to ensure mercury levels do not rise above this two ppb threshold.

With mercury being such a toxic element and compliance in place to ensure its careful regulation, it’s crucial to have trusted solutions in place that can prevent contamination events and ensure high levels of mercury do not enter the surrounding environment.

What are the Issues with Mercury in Water?

Mercury contamination in water sources poses significant environmental and public health concerns due to its toxic properties and potential long-term consequences. Here are key issues associated with mercury in water:

• Health Risks: Mercury is a potent neurotoxin that can cause serious health problems in humans, even at low concentrations. Chronic exposure to mercury through contaminated water can lead to neurological disorders, developmental delays in children, cardiovascular issues, and kidney damage. Pregnant women and young children are particularly vulnerable to the adverse effects of mercury exposure, as it can harm fetal development and cognitive function.
• Bioaccumulation: Mercury has a tendency to accumulate and biomagnify in aquatic food chains. Microorganisms convert inorganic mercury into methylmercury, a highly toxic form that accumulates in fish, shellfish, and other aquatic organisms. Predatory fish at the top of the food chain, such as tuna and swordfish, can contain high levels of methylmercury, posing risks to consumers who consume these contaminated seafood products.
• Ecosystem Impact: Mercury contamination can disrupt aquatic ecosystems, affecting biodiversity, food webs, and ecosystem functions. Methylmercury accumulation in aquatic organisms can lead to reproductive failure, reduced growth rates, and population declines in sensitive species. Changes in ecosystem structure and function can have cascading effects on ecosystem services, including water purification, nutrient cycling, and carbon sequestration.
• Regulatory Concerns: Governments and regulatory agencies worldwide have established guidelines and standards for mercury levels in water to protect human health and the environment. Compliance with these regulations poses challenges for industries, municipalities, and other stakeholders, requiring effective monitoring, treatment, and mitigation measures to ensure water quality and safety.
• Sources of Contamination: Mercury contamination in water can originate from both natural and anthropogenic sources. Natural sources include volcanic eruptions, weathering of mercury-containing minerals, and atmospheric deposition. Anthropogenic sources include industrial activities such as coal combustion, mining, metal smelting, and wastewater discharges. Contaminated runoff from landfills, agricultural areas, and urban areas can also contribute to mercury pollution in water bodies.
• Treatment Challenges: Removing mercury from water sources can be challenging due to its chemical properties and persistence. Conventional treatment methods such as coagulation, sedimentation, and filtration may be ineffective for mercury removal. Advanced treatment technologies such as activated carbon adsorption, ion exchange, and membrane filtration may be required to reduce mercury concentrations to acceptable levels.
