Maine firefighting foam spill: water tests show safe levels

In Brunswick, Maine, a significant environmental incident occurred on August 19 when a fire suppression system at the Brunswick Executive Airport accidentally discharged over 1,400 gallons of firefighting foam mixed with 50,000 gallons of water. This incident is noted as the largest recorded spill of its kind in the state. The foam contained per-and polyfluoroalkyl substances (PFAS), which are linked to various health issues, including cancer. Following the spill, the Maine Department of Environmental Protection (DEP) initiated an investigation and sampled 34 water supplies in the vicinity, finding that all tested samples were below the guidelines for dangerous chemicals. The DEP has committed to ongoing monitoring, with plans to test the water supplies every three months for a year. Additionally, surface water results from the nearby watershed have shown a decline in PFAS concentrations, although they have not yet returned to pre-spill levels. The agency is also evaluating soil samples from areas most likely impacted by the foam release, with preliminary results indicating the presence of PFAS in all tested soils. In response to the spill, the Maine Center for Disease Control and Prevention issued advisories to limit the consumption of freshwater fish from affected water bodies and to avoid recreational activities that could lead to contact with contaminated waters. The foam was removed after the incident, but the long-term effects on the environment and public health remain a concern. The situation highlights the ongoing challenges posed by PFAS, often referred to as 'forever chemicals' due to their persistence in the environment. As investigations continue, the state is taking steps to mitigate risks and protect public health.
