"Generation
In 1999, Texas industries and businesses pro-duced about 15 million tons of hazardous waste, excluding hazardous wastewaters--more than one-third of all such waste in the United States. The multitude of chemical manufacturers, petroleum refineries, and other industries in the region produces a large portion of this toxic refuse. Harris, Brazoria, and Galveston counties are the top three hazardous waste producers in Texas, together creating almost two thirds of the state's total.
Disposal
More than 99 percent of Texas hazardous waste is managed on site or treated and discharged into a wastewater treatment facility. In 1994, there were twenty approved or active hazardous waste incinerators and eight deep injection wells in the Houston area. Most hazardous wastes generated in the region are disposed of by deep well injection.
Contaminated Sites
The region has a relatively high concentration of sites contaminated by hazardous materials. The county is among the top ten counties in the United States with the most Superfund sites.
There are currently seventeen federal or state Superfund sites in Harris County that are on the EPA's National Priorities List. Scores of other contaminated sites, such as brownfields, exist as well, but are not officially tracked. The year 2003 saw the beginning of remediation on the MDI Superfund site, located in Houston's Fifth Ward, across the street from Brooks Elementary School. The cleanup project was unique in that community involvement was the driving force. Mothers for Clean Air and an outreach effort of the University of Texas Medical Branch used art to involve neighborhood parents and children. The city applied again this year for federal fund-ing to clean up area brownfields.
Inequity
Like many environmental problems, haz-ardous waste disposal most affects low-income and minority neighborhoods. Texas is one of five states having the most commercial waste facilities in communities above the national average in percentage of people of color. Studies also show a strong negative correlation between proximity of hazardous waste facilities or contaminated sites and property values. Often, contaminated sites are cleaned up only to be turned back over to commercial interests, leading to the gentrification of neighborhoods."
