Jefferson County, Texas: drinking water report. Jefferson County on the Gulf Coast of Texas has about 256,000 residents, with Beaumont and Port Arthur as
Jefferson County on the Gulf Coast of Texas has about 256,000 residents, with Beaumont and Port Arthur as the major cities. The county sits at the center of the Golden Triangle refining complex – one of the largest concentrations of petrochemical facilities in the world. Water comes from the Neches River and Pine Island Bayou, sources that flow through industrial corridors before reaching municipal intakes.
Petrochemical discharge and spill history define Jefferson County's water quality environment. According to the EPA's Toxics Release Inventory for 2024, Jefferson County facilities reported releasing over 14 million pounds of toxic chemicals, including benzene, 1,3-butadiene, and ethylene oxide. While most releases go to air, wastewater discharges to the Neches River include treated effluent from multiple refineries and chemical plants.
The EPA's UCMR5 data detected PFAS in both the Beaumont and Port Arthur water systems. AFFF use at the former Naval Station Beaumont and at industrial firefighting facilities throughout the refinery complex contributed to widespread low-level PFAS in the watershed. A 2024 TCEQ investigation found combined PFAS at 14 ppt in the Neches River at the Beaumont intake.
Jefferson County's industrial density means your water source carries the accumulated discharges of dozens of facilities. Treatment plants address regulated contaminants, but the sheer variety of compounds in the source water warrants household-level attention.
Check your water for the latest results. For the mix of industrial organics and PFAS present in Gulf Coast water, reverse osmosis at the kitchen tap provides the most comprehensive protection.
