Old Landfill Corrective Measures Project
Summary
The final piece of Sheridan's landfill cleanup is underway: a $3.17 million construction contract to lower the groundwater table at the old landfill site near the dog and cat shelter, keeping contaminants from migrating. The state pays about 75%, and once this is done, the landfill remediation saga is over.

Impact analysis
City share is roughly $800,000 (25%) of the $3.17 million construction cost, covered by an existing $3.7 million SRF loan across both landfill projects.
Everyone downstream of the old landfill — cleaner groundwater and closure of a decades-old environmental liability.
Neighbors may notice some odor from the evaporation ponds; dog walkers will see construction and a larger pond area until fencing is in place.

The city is wrapping up a decade-long cleanup of groundwater contamination from the unlined old landfill near the dog and cat shelter. The $3.17M final project installs dewatering wells, evaporation ponds, and a soil cover — and the state pays 75%.

The old Acme power plant will be fully demolished this summer with contaminated soil capped on-site, and fire-recovery monitoring equipment is going in upstream of the city's water intake.
