HOUGHTON, Mich. (WLUC) – Biosolid spreading at the Mason Stamp Sands has local residents still concerned but experts from Michigan Tech are speaking up on the subject.
“It’s not surprising that people have questions about biosolids because most people don’t think about the whole wastewater treatment process,” said Jennifer Becker, Civil and Environmental Engineering professor.
Top questions include impact on water supply and wildlife.
“We can’t say there is absolutely no risk because there is nothing I can think of that we do that has no risk,” said Becker.
But biosolids are processed to the point where experts says health risks are very low, even in unlikely cases of high contact with the material.
“So, for example, for many of the metals this would be a child actually eating the biosolids. This gives you a feel for the regulations. They are based on a very extreme case,” said Eric Seagen, also a Civil and Environmental Engineering professor at MTU.
