The below information has been provided in an effort to help keep the community informed on a more frequent basis about progress at the AltEn site.
Ever since AltEn ceased operations at its facility in Mead in 2021, the AltEn Facility Response Group (FRG) has been voluntarily working under the guidance of the Nebraska Department of Environment and Energy (NDEE) to stabilize the AltEn site and develop a Remedial Action Plan (RAP) for the site. The FRG’s top priorities have been and continue to be to help ensure the safety of the surrounding community and environment. To-date, there has been no evidence of impacts to local drinking water.
The FRG is working diligently with the NDEE to identify the most effective and safest methods to address the current environmental conditions on the AltEn site. The remedial action plans (RAP) will recommend remediation for components remaining on-site, including wastewater, sludge, and wet cake.

May Community Update: Wet Cake Progress
Progress marches on with more wet cake removed from the site. This month also includes an update about groundwater monitoring results. In addition, the FRG is developing the Lagoon Solids Remedial Action Plan (RAP), which is due June 30.
Wet Cake Removal
An average of 1,000 tons of solidified wet cake is being transported off site daily and more than 38,000 tons have been removed so far this year, bringing the total to over 96,000 tons. The FRG remains on track to complete wet cake removal by the end of 2025.
Groundwater Monitoring
Groundwater samples were collected in March, with results showing no pesticides exceeding screening levels, with the exception of one compound at MW5 – located immediately adjacent to the Northwest Lagoon – and its concentration continues to decrease.
