Park County, CO - Park County Development Services has issued a Director Determination according to the Park County Land Use Regulations, finding that the application of biosolids, sewage, sewage sludge, and septage onto or into the soil within the County is prohibited. This action follows growing concern over potential long-term risks to human health and the environment, especially in rural communities dependent on private wells and septic systems.
A copy of the Director Determination is available for public review and inspection on the County’s website: Interpretation of Use - Biosolid, Sewage, Sewage Sludge, & Septage Application.
"Park County’s top priority is protecting our residents and our natural resources," said Brandon Heacock, Director of Development Services and Planning Director. "Given the lack of updated regulations at the state and federal level, we cannot allow the land application of biosolids without clear and enforceable safety standards in place."
Why This Matters
Biosolids, a byproduct of municipal wastewater treatment, or Dewatering practices and septage pumped from septic tanks, are sometimes used as agricultural soil amendments. However, it is possible they may contain harmful contaminants such as PFAS (so-called 'forever chemicals'), pharmaceuticals, microplastics, and heavy metals. These substances could accumulate in soil and groundwater and may pose risks to human and environmental health.
Local Risks and Vulnerability
Park County’s unique geography and rural infrastructure increase the risk of groundwater contamination. Many residents rely on private wells and septic systems. Adding biosolids to the environment, without comprehensive testing and monitoring, poses an unacceptable risk.
What’s Next
Development Services will move to codify the prohibition into the Park County Land Use Regulations at a future date.
Until federal and state agencies provide modern, science-based safety standards for biosolids, their use in Park County will remain strictly prohibited.
