Who are the mystery men dumping carcinogens into our water shed?
“I’m assuming that it’s coming from the Haw River, from the Greensboro area,” Christiansen said this week in a telephone interview. “My wishful thinking is that they are going to find the source and eliminate it. It seems to me it would to be pretty easy to backtrack. I would think it would be pretty easy to have a list of what the industries are (that might use dioxane).
In line with Christiansen’s thought about the ease of putting together a list of industrial sites likeliest to be 1,4 dioxane sources, Drew said “we do have an idea of who a few of the largest contributors of 1,4 dioxane to our sewer collection system might be.” But city officials don’t want to “name or implicate possible dischargers while they perform their due diligence and investigative work.”
Like many industrial chemicals, the "acceptable" level in drinking water varies by regulatory agencies. Some have set it as low as .07 parts per billion, while others go up to 3 PPB. But Sanford is dealing with twice that higher level all the way downstream, because the levels upstream are huge:
