Well Water Near AltEn in Saunders County, NE

For most of Saunders County, well water is a routine question of which of two Natural Resources Districts covers a parcel. Near the former AltEn ethanol plant outside Mead, it is not routine at all: state and university testing has confirmed pesticide contamination in groundwater and in nearby homes, and a permanent environmental covenant will restrict how the site itself can be used long after active remediation ends.

This page covers what's specific to Saunders County. For the general explanation, see the national guide.

What testing has actually confirmed, not just what cleanup is planned

The hub covers the state's remedial action plan for AltEn's lagoon solids; the underlying well-water testing behind that plan is worth understanding on its own. Groundwater sampling from test wells drilled in the vicinity of the former plant has shown pesticide contamination in the large majority of wells tested -- reporting on the site's investigation found eight of nine test wells carrying some detectable level of contamination. Separately, testing of private wells at homes near the plant found neonicotinoid pesticide levels significantly higher than comparison samples taken from homes in nearby communities, indicating the contamination is not confined to the immediate plant footprint but has reached at least some residential groundwater in the surrounding area. This is the specific, well-water-focused evidence behind the county hub's broader statement that the AltEn cleanup is a real, active process rather than a closed historical matter.

Response and monitoring work is ongoing rather than finished: the AltEn Facility Response Group (AFRG), the entity managing remediation, has continued quarterly groundwater monitoring and has installed additional monitoring wells along the property's boundaries to track how far contamination extends and whether it is changing over time. Soil sampling has extended to farm fields in the surrounding area that received land-applied wastewater or wetcake byproduct from the plant during its operation, and the state's own remedial action plan for on-site soils was due to DWEE by August 31, 2026 -- meaning some elements of the cleanup's technical scope were still being finalized as of this research, not already complete.

A permanent land-and-water-use restriction, not just a cleanup with an end date

One detail buyers should know that goes beyond a typical remediation timeline: the settlement covering the AltEn site includes a permanent restriction on how the property itself can be used going forward, even once active remediation work is complete. Under that settlement, the site cannot be used for homes, schools, or child care facilities -- a restriction written directly into the resolution of the contamination, not a temporary construction-era precaution. The state also retains ongoing authority to sample the property's soil and water for contamination and to monitor for problems that could affect water used for agricultural purposes on or near the site, meaning DWEE oversight of this specific property is expected to continue indefinitely rather than end once the current remedial action plan is executed.

For a buyer evaluating land near Mead, the practical verification steps are specific and worth doing directly rather than relying on a seller's characterization: first, check the current AltEn public record maintained by DWEE for the parcel's location relative to the site boundary, the environmental covenant area, and any documented land-application history on specific fields. Second, if a private well already serves or would serve the parcel, have it independently tested for neonicotinoid pesticides and related contaminants rather than assuming municipal-style safety, since Nebraska's public drinking-water standards and enforcement mechanisms apply differently to private domestic wells than to a municipal water system. Third, ask specifically whether the parcel or a field on it is known to have received AltEn wastewater or wetcake in past years, since that history -- documented separately from the plant site itself -- is what has driven the surrounding soil and groundwater sampling described above.
