Concerns raised over 'forever chemicals' detected at Corpus Christi's planned desalination site

In a recent memo, environmental advocacy groups have raised concerns about the presence of per- and polyfluoroalkyl substances (PFAS) in the Inner Harbor Ship Channel. This area is set to be the source of water for a new desalination plant in Corpus Christi. The memo, based on an analysis by William “Jim” Rogers, highlights potential health risks associated with PFAS, which are linked to serious health issues according to federal research.

Drew Molly, chief operating officer of Corpus Christi Water, acknowledged awareness of PFAS presence and noted that measures were already being considered. "PFAS and other micro-contaminants have always been considered in the approach for designing the Inner Harbor Water Treatment Campus," city officials stated.

The pilot plant aims to test treatment processes before constructing a full-scale facility capable of producing 30 million gallons of treated water daily. Despite concerns, Molly expressed confidence in existing treatment technologies: "The City is confident that the proven treatment technology will address all contaminants."

Environmental groups urge further studies and risk assessments before continuing with construction. They emphasize that even small amounts of PFAS could pose significant public health risks due to their persistence and accumulation over time.

According to experts, regulations on PFAS levels in drinking water are forthcoming but not yet established for wastewater. The Texas Commission on Environmental Quality anticipates compliance monitoring beginning in 2027.

Rogers' analysis found PFOS levels exceeding federal guidelines in some samples from November 2024. However, Mark Boyd, an environmental engineer not affiliated with the project, suggested more data is needed before halting progress: "Further sampling and data review are clearly warranted."

Concerns also extend to brine discharge potentially concentrating PFAS and affecting marine life. Molly mentioned plans for monitoring stations near discharge points as part of ongoing evaluations.

The city remains committed to addressing any regulatory changes and ensuring safe operations at the desalination facility.
