How unsafe is the fecal matter on Texas beaches?

Testing is conducted by the state in varied frequencies. “Texas fared pretty poorly compared to other areas: 90% of our beaches with at least one day with unsafe fecal bacteria.



The presence of fecal matter on Texas beaches, often measured by Enterococcus bacteria levels, is a recurring public health concern that varies significantly by location and recent weather events. High levels of these bacteria usually indicate contamination from storm runoff, leaking septic systems, or sewage overflows, which can increase the risk of skin rashes, ear infections, and gastrointestinal illnesses for swimmers. According to environmental reports in early 2026, beaches in the Galveston and Corpus Christi areas occasionally see "advisories" where bacteria levels exceed safety thresholds, particularly after heavy rain. While the Texas General Land Office monitors these levels through the "Texas Beach Watch" program, the water is rarely "deadly," but it can be genuinely "unsafe" for children, the elderly, or those with compromised immune systems. To stay safe, travelers should always check the live "Beach Watch" map before entering the water and avoid swimming near storm drains or piers, especially within 48 hours of a significant rainfall event, as the runoff can spike bacteria counts to levels that make the water unsuitable for primary contact.
