Protecting Maryland Water from PFAS Pollution

The Maryland General Assembly is considering a bill to restrict PFAS discharge from large industries into our waterways and to wastewater treatment plants.

Toxic threats

The Maryland Department of Environment has found toxic PFAS “forever chemicals” in some of Maryland’s drinking water. According to the U.S. Environmental Protection Agency, there is no safe level of some PFAS in drinking water and exposure to PFAS chemicals, even in small amounts over time, has been linked to serious health effects including cancer, thyroid disruption and reduced vaccine response.

Accordingly, the EPA has proposed a maximum contamination level of 4 ppt for several PFAS in drinking water, which is a big step forward from the previous advisory of 70 ppt.

We’re calling on the Maryland General Assembly and the Moore Administration to protect our families by establishing strict limits for PFAS discharge into our waterways and to wastewater treatment plants.

PFAS in Maryland

The Maryland Department of Environment (MDE) has found PFAS in the majority of water treatment plants they have tested. According to Maryland’s PFAS Action Plan 14% of Maryland industries that responded to a survey reported having PFAS sources on-site.

In some cases, manufacturers and users of these chemicals are dishcarging them directly into our rivers, lakes and streams. Other companies might be “indirectly” discharging PFAS by sending it to treatment plants. This toxic pollution threatens not only our drinking water but also fish and wildlife.

There is known contamination in and around more than a dozen military sites and in seafood in Maryland

In 2022, the Maryland General Assembly passed the George “Walter” Taylor Act, with broad bi-partisan support to restrict the use of PFAS in food packaging, rugs and carpets, and firefighting foam in Maryland.

The “forever chemicals”

PFAS have been given the nickname “forever chemicals” because they don’t break down in our bodies or in the environment. So the more they get used, the more they build up and the bigger the risk they pose to our health. This is particularly concerning for our kids who could be exposed to these chemicals for decades to come.

According to a 2020 report from leading PFAS experts PFAS should be regulated as a class in order to protect health:

“Managing PFAS one-by-one is neither feasible nor cost-efficient. More comprehensive solutions are needed, given that traditional approaches have failed to control widespread exposures to PFAS and resulted in inadequate public health protection. We suggest class-based options to more comprehensively and efficiently reduce PFAS exposure.

Protecting our communities

The best way to address PFAS contamination and all that comes with it, is to prevent it in the first place. Until we can fully phase out the use of PFAS, we need to prevent industries from releasing these chemicals into our waterways.

The EPA has made clear that states can restrict PFAS discharges under the Clean Water Act. Moreover, existing pollution control technology can capture roughly 99 percent of PFAS in wastewater.

Maryland should limit PFAS discharge into our waterways, sewage treatment plants and stormwater. Now is the time for the state to act.

The Protecting State Waters From PFAS Pollution Act (SB956/HB1153)

In May, Gov. Wes Moore signed the Protecting State Waters From PFAS Pollution Act into law. The law was authored by State Sen. Katie Fry Hester and Delegate Sara Love to mitigate and monitor PFAS discharge from some large industrial users in Maryland. The policy earned broad bipartisan support in the legislature.

The law directs the Maryland Department of Environment to work with wastewater treatment plants to identify and require the testing and monitoring of discharge from some large industries that use PFAS chemicals.

Gov. Moore signs the Protecting State Waters From PFAS Pollution Act alongside Sen. Hester, Del. Love, staff, Speaker Jones, Senate President Ferguson, the Maryland Dep. of Environment, Maryland PIRG and Waterkeepers Chesapeake.

What’s next?

Utlimately we need to phase out the use of all PFAS. Until that happens we should ensure polluting industries bear responsibility for preventing PFAS contamination in our waterways and drinking water, preventing Maryland taxpayers and families from paying the costs with our health and pocketbooks.

We hope the Maryland Department of Environment will use it’s power to set strict limits for PFAS disharge and require that:

  • Companies that use PFAS must use modern technology to filter out PFAS from wastewater.
  • PFAS contaminants captured by industry be safely stored or disposed of and not be put in incinerators, municipal landfills, or applied to land.
  • Hold accountabile industries that violate the law.
