Biosolids Research in Colorado with Dr. Jim Ippolito

“The Clean Water Act and Biosolids: A 45-Year Chronological Review of Biosolids Land Application Research in Colorado” with Dr. Jim Ippolito

Biosolids are the human waste products that are managed and produced by wastewater treatment plants. While many simply flush and forget their waste, biosolids can have a variety of advantageous environmental impacts when applied at proper rates and locations. In this episode, as part two of our miniseries on the Clean Water Act, Dr. Jim Ippolito discusses how researchers have utilized these benefits across various land types in Colorado.

Tune in to learn:

  • How biosolids can turn mining-affected dead spots into flourishing fishing getaways
  • How biosolids can create sustainable rangelands for cattle
  • Why Colorado has been such a hot spot for environmental quality research
  • How researchers tackled the time-bomb theory
