TEXAS — A local environmental group says the state needs to step up its pollution standards, especially in the wake of Hurricane Harvey.

Andrew Dobbs with the Texas Campaign for the Environment said Harvey left behind a lot of toxic chemicals, some of which still aren't cleaned up.

Dobbs and his team are canvassing neighborhoods with a flyer encouraging folks to call the Texas Commission on Environmental Quality to urge them to lower the level of acceptable pollutants.

Dobbs said that in some cases Texas pollution standards are 1,500 times weaker than national standards.

"When Hurricane Harvey hit, we saw all these Superfund sites and all these polluted sites in and around the city, inundated with water and that water then washing away polluting local waterways and into people's homes,” he said. “We're already starting to see the health effects of this."

Dobbs and his team plan on presenting their information to state lawmakers.
