A project to provide coordinated, comprehensive outreach campaigns in six communities in the coastal zone of Texas to reduce fecal bacteria pollution.

Project Area

River Basins: Neches-Trinity and San Jacinto-Brazos

Water Bodies: Bastrop Bayou (1105) and Double Bayou (2422)

Location: Brazoria, Chambers, and Galveston counties


Nearly 50 percent of water bodies in the Houston-Galveston region do not meet all water quality standards because bacteria concentrations exceed the criteria used to evaluate attainment of the primary contact recreation use. This includes waters within the six small, coastal communities in the region with no municipal separate storm sewer system (MS4) permits: Anahuac, Bailey’s Prairie, Bonney, Danbury, Oak Island, and Rosharon. Municipalities with MS4 permits are required to develop stormwater management programs to mitigate pollutants entering water bodies. All communities in the project area are within watersheds with a U.S. Environmental Agency-accepted watershed protection plan.

Project Description

The Houston-Galveston Area Council (H-GAC) developed water quality education and outreach campaigns in these coastal zone communities, to change behaviors and reduce bacteria levels. H-GAC provided resources to develop, launch, and implement public outreach campaigns addressing causes of bacteria impairments. 

As part of the outreach campaigns, H-GAC conducted a community needs assessment, created a public outreach plan, and provided literature, presentations, trainings, and tools. H-GAC also established regional education programs for pet waste, fats, oils, grease, and littering in these communities.

This project ended in 2020.
