The Environmental Protection Agency says it has reviewed aerial imagery showing 13 Superfund sites in Texas that have been flooded by Harvey and are "experiencing possible damage" due to the storm.
EPA's statement comes hours after The Associated Press reported that its journalists had visited seven Superfund sites in the Houston area in recent days. They found the sites to either be underwater or showing signs they were inundated before floodwaters receded.
The EPA statement confirms the AP's reporting that the federal agency has not yet been able to physically visit the Houston-area sites, saying the sites have "not been accessible by response personnel."
The AP used a boat to visit one site, and it accessed others with a vehicle or on foot.
The EPA hasn't immediately responded to questions about why its personnel have been unable to do so.
