This is a list of Superfund sites in Texas designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.

The EPA placed the Brio site on the National Priorities List in 1984. Beginning in 1989, the EPA began remediation by demolishing buildings, digging out contaminated soils for processing or disposal, containing groundwater by use of a physical barrier, and capping the site. [1] The site was removed from the National Priorities List in 2006. [5]
Topsoil runoff from farm, central Iowa (2011). Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and manufacturing industries—although laws and regulations introduced in the late 20th century have improved water quality in many water bodies.

Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way into groundwater.This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant, or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution.
Environmental impact of fracking in the United States has been an issue of public concern, and includes the contamination of ground and surface water, methane emissions, [1] air pollution, migration of gases and fracking chemicals and radionuclides to the surface, the potential mishandling of solid waste, drill cuttings, increased seismicity and associated effects on human and ecosystem health.
Groundwater is also used by farmers to irrigate crops and by industries to produce everyday goods. Most groundwater is clean, but groundwater can become polluted, or contaminated as a result of human activities or as a result of natural conditions. The many and diverse activities of humans produce innumerable waste materials and by-products ...
[16]: 206–208 Even if the source of contamination had a permit for its operation that may not avoid groundwater contamination liability. [ 16 ] : 213 The liability and high costs of groundwater cleanup can cause businesses to abandon problem sites leaving significant long-term financial losses to the community. [ 24 ]
Located in South Central Texas, the Edwards Aquifer encompasses an area of approximately 4,350 square miles (11,300 km 2) that extends into parts of 11 counties. [3] The aquifer's boundaries begin at the groundwater divide in Kinney County, East of Brackettville, and extend Eastward through the San Antonio area and then Northeast where the aquifer boundary ends at the Leon River in Bell County ...
