The Harris County Attorney enforces laws regulating air pollution, water pollution, sewage disposal, hazardous and other solid waste disposal, drinking water contamination, flood plain management, and public health nuisances. We work with investigators from the Harris County Public Health and Environment Services, the Texas Commission on Environmental Quality, the Environmental Protection Agency, the Coast Guard, and the City of Houston.  We also consult air emission events data to determine where enforcement upon major unauthorized emitters of toxic pollutants might reduce environmental harm associated with carcinogens and materials known to cause birth defects and numerous other adverse health-based risks.
