The worst flooding disaster in modern US history last year when Hurricane Harvey deluged Houston last year also released millions upon millions of gallons of toxic chemicals into the city's water, land, and air. It turns out the environmental disaster and the toxic health hazard to the people of Houston and the surrounding area is far, far worse than reported six months ago.
A toxic onslaught from the nation’s petrochemical hub was largely overshadowed by the record-shattering deluge of Hurricane Harvey as residents and first responders struggled to save lives and property.
More than a half-year after floodwaters swamped America’s fourth-largest city, the extent of this environmental assault is beginning to surface, while questions about the long-term consequences for human health remain unanswered.
County, state and federal records pieced together by The Associated Press and The Houston Chronicle reveal a far more widespread toxic impact than authorities publicly reported after the storm slammed into the Texas coast in late August and then stalled over the Houston area.
Some 500 chemical plants, 10 refineries and more than 6,670 miles of intertwined oil, gas and chemical pipelines line the nation’s largest energy corridor.
Nearly half a billion gallons of industrial wastewater mixed with storm water surged out of just one chemical plant in Baytown, east of Houston on the upper shores of Galveston Bay.
Benzene, vinyl chloride, butadiene and other known human carcinogens were among the dozens of tons of industrial toxins released into surrounding neighborhoods and waterways following Harvey’s torrential rains.
In all, reporters catalogued more than 100 Harvey-related toxic releases — on land, in water and in the air. Most were never publicized, and in the case of two of the biggest ones, the extent or potential toxicity of the releases was initially understated.
And if you think GOP Gov. Greg Abbott and Texas Republicans are going to lift a finger to hold these companies liable for the toxic waste dump that America's fourth-largest city was turned into, you've not been paying attention.
Only a handful of the industrial spills have been investigated by Texas and federal regulators, reporters found.
Texas regulators say they have investigated 89 incidents, but have yet to announce any enforcement actions.
Testing by state and federal regulators of soil and water for contaminants was largely limited to Superfund toxic waste sites.
Based on widespread air monitoring, including flyovers, officials repeatedly assured the public that post-Harvey air pollution posed no health threat. But the U.S. Environmental Protection Agency official in charge now says these general assessments did not necessarily reflect local “hotspots” with potential risk to people.
Regulators alerted the public to dangers from just two, well-publicized toxic disasters: the Arkema chemical plant northeast of Houston that exploded and burned for days, and a nearby dioxin-laden federal Superfund site whose protective cap was damaged by the raging San Jacinto River.
Samuel Coleman, who was the EPA’s acting regional administrator during Harvey, said the priority in the immediate aftermath was “addressing any environmental harms as quickly as possible as opposed to making announcements about what the problem was.”
In hindsight, he said, it might not have been a bad idea to inform the public about the worst of “dozens of spills.”
Of course the state GOP was sitting on this information so that when the cancer and birth defect numbers started to pour in over the next several years they would shrug and blame residents (and cut public health programs some more, probably).
It'll take years to rebuild, but the environmental damage to Houston and Texas's Gulf Coast will last for decades.
