Water Quality in Galveston County, TX

Galveston County extends from the mainland suburbs south of Houston to Galveston Island, serving about 350,000 residents. Water comes primarily from surface sources through the Gulf Coast Water Authority, which draws from the Brazos River. The island community of Galveston receives water via a pipeline from the mainland. Hurricane vulnerability and saltwater intrusion are constant infrastructure concerns.

What the Data Shows

Galveston County's coastal location creates unique water quality dynamics. Hurricane storm surge can flood infrastructure, and saltwater intrusion threatens groundwater sources near the coast. The 2008 Hurricane Ike caused extensive damage to water infrastructure on Galveston Island and the Bolivar Peninsula.

UCMR5 data shows low-level PFAS detections in county systems. Scholes International Airport on Galveston Island and industrial facilities along the Houston Ship Channel's southern reach are potential PFAS sources. According to the TCEQ's 2024 compliance data, county systems met federal standards.

What Galveston County Residents Should Do

Coastal communities should have backup water plans for hurricane season. Saltwater intrusion and storm-related quality disruptions are real risks.
