Colorado Public Radio: Colorado regulators have accused two environmental consulting companies of falsifying soil and water sampling data collected at hundreds of oil and gas sites in Weld County. 

In a press statement released Tuesday, the Energy and Carbon Management Commission claimed the firms filed falsified data for 350 oil-field operations between 2021 and summer 2024. The consulting companies — Eagle Environmental Consulting and Tasman Geosciences — submitted the altered tests from spill sites and closed drilling locations on behalf of three oil and gas companies: Chevron, Civitas and Occidental Petroleum.

The agency said there does not appear to be an immediate threat to public health and regulators are working to determine which sites require further cleanup and remediation. Representatives for the consulting companies did not immediately respond to a request for comment from CPR News.
