Please continue checking here for new information.

Progress Continues in Winter 2023-2024

While the Solid Waste Pilot Project is pausing wet cake removal until Spring 2024, the FRG’s work on the stabilization and long-term management of the AltEn site will continue throughout the Winter.  Site managers, health and safety professionals and scientists are on site daily and continue to manage several site activities.  We will remain actively engaged on the following areas:

  • Conducting regular groundwater testing to confirm public safety. Your groundwater continues to be safe based on the most recent results.
  • Analysis of soil samples from under the wet cake pile.
  • Treating lagoon water for additional farmland application this Spring to meet increased demand from local farmers.

The responsible, safe remediation of the AltEn site in Mead, Nebraska.

The AltEn Facility Response Group (FRG), as part of Nebraska’s Voluntary Cleanup Program (VCP) and under the direction of the Nebraska Department of Environment and Energy (NDEE), has stabilized the site.  

The FRG developed a Remedial Action Plan (RAP) for water stored at the site and is committed to implementing the Water RAP. So far, the FRG has treated over 49 million gallons of process water – 31 million gallons of which has been applied to local farms as a beneficial nutrient source. 

The FRG also is developing a RAP for the on-site solids and continues to investigate remediation options for the solid materials at the AltEn site in order to submit the Solids RAP.


As this work continues, the FRG’s top priority is to ensure the continued safety of the surrounding community and environment. NDEE testing has consistently shown no evidence of impacts to water.


This website is a key resource for updates and information about the FRG’s remediation efforts.
