On March 13, 2025, Maryland lawmakers introduced House Bill 386, a significant legislative measure aimed at regulating the use of pesticides containing per- and polyfluoroalkyl substances (PFAS). This bill seeks to address growing public health concerns associated with these chemicals, which are commonly found in various consumer products and have been linked to adverse health effects.

The primary purpose of House Bill 386 is to prohibit the use of PFAS pesticides in specific sensitive environments, including healthcare facilities, schools, daycare operations, residential lawns, and commercial mosquito spraying. The bill mandates the Maryland Department of Agriculture to compile and maintain a list of registered PFAS pesticides, which must be made publicly accessible by January 1, 2026. This transparency aims to inform certified applicators and the general public about the potential risks associated with these chemicals.

Key provisions of the bill include a clear definition of PFAS chemicals and the establishment of a timeline for compliance. Beginning June 1, 2026, the use of any pesticide containing PFAS will be strictly prohibited in the aforementioned settings. This move reflects a growing recognition of the need to protect vulnerable populations, particularly children and patients, from the harmful effects of these substances.

The introduction of House Bill 386 has sparked notable debates among stakeholders. Proponents argue that the bill is a necessary step toward safeguarding public health and the environment, as PFAS chemicals have been linked to serious health issues, including cancer and immune system dysfunction. Critics, however, express concerns about the potential economic implications for agricultural practices and pest control industries that rely on these pesticides.

The bill's implications extend beyond immediate health concerns; it also signals a broader shift in regulatory attitudes toward chemical safety in Maryland. Experts suggest that if passed, House Bill 386 could pave the way for similar legislation in other states, reflecting a growing national movement to limit the use of harmful chemicals in agriculture and public spaces.

As the legislative process unfolds, stakeholders will be closely monitoring the discussions surrounding House Bill 386. The outcome could significantly impact public health policy and environmental regulations in Maryland, setting a precedent for future legislative efforts aimed at reducing exposure to hazardous substances.
