Maryland lawmakers introduce bill to limit PFAS levels

Two lawmakers in Maryland are working on a bill to regulate "forever chemicals" that come from wastewater treatment plants. These chemicals, known as PFAS, can be harmful to human health. The bill is sponsored by Senator Sara Love and Delegate Dana Stein. It aims to limit the amount of PFAS released into waterways from sewage sludge. This sludge is often used as fertilizer on farms, which can then contaminate food and drinking water. Senator Love explained that many people may not realize biosolids are used as fertilizer. She wants to set a limit on PFAS levels in these materials. The bill proposes an initial limit of 50 parts per billion, which would be reduced to 25 parts per billion after three years. Love believes that most of Maryland's wastewater treatment plants can meet these standards. Despite concerns about public health, some leaders in the waste industry have not supported the bill yet. They say they need more data before making a decision. Delegate Stein highlighted the risk of PFAS runoff in the Baltimore area, where two wastewater plants are located. He believes the bill will help ensure safety for residents using land where treated sludge is applied. Environmental groups support the bill, saying it could make Maryland a leader in tackling PFAS contamination. They emphasize the importance of protecting drinking water sources and vulnerable locations, like schools.
