Biosolids Land Application in October 2018

The City of Athens will be land applying biosolids material on the fields off of Enlow Road and Hebbardsville Road beginning in October 2018. Biosolids are primarily organic material produced during wastewater treatment.  Land application of these biosoilds is a beneficial use of this material that will supply nutrients and replenish organic matter to these fields. 

Recycling biosoilds through land application serves several purposes:

  • Improves soil properties, such as texture and water holding capacity, providing favorable conditions for root growth and increased drought tolerance. 
  • Biosolids land applications supply nutrients essential for plant growth, including: nitrogen, phosphorus, and essential micro nutrients such as zinc and copper.
  • Biosolids land application prevents these nutrient rich solids from being wasted and is an environmental friendly alternative to expensive chemical fertilizers.
  • Biosolids land application is a sustainability initiative that diverts material from landfills.

The Ohio Environmental Protection Agency (OEPA) requires that biosolids undergo a stabilization process before land application. This stabilization process minimizes odors and destroys pathogens. Additional OEPA requirements include: 

  • Restricting public access to the application site
  • Limiting livestock grazing
  • Controlling crop harvesting schedules 

Biosolids material are physically worked into the ground and do not sit on the surface. This is an OEPA approved and regulated site. The OEPA has strict regulations on how, when, and where we can apply the biosolids material 

If you would like additional information about the benefits of land applications, or have any questions about the process, please contact Robert Heady, City Engineer and Director of Public Works. He can be reached at (740) 593-7636 or email
