Parachute Creek tests show ‘non-detect’ results

PARACHUTE — A week’s worth of tests of Parachute Creek north of here, where a leaky pressure gauge spilled thousands of gallons of natural-gas liquids into the ground, have shown no signs of continuing contamination from the leak, a spokesman for the state health department wrote in an email to the Post Independent on Friday.

“I heard from our folks this morning that it has been six consecutive days that all surface water sampling locations have come back as non-detect,” wrote Mark Salley, public information official for the Colorado Department of Public Health and Environment (CDPHE).

In addition, Salley wrote, “Monitoring continues, surface water [of the creek] and groundwater, and shows at this time the plume is stable” …

… Donna Gray, with the community relations office for Williams Midstream, the company playing the key role in the cleanup of the plume and its effects, said that “not much has changed. We continue to do the air sparging, and that seems to be working very well” …

… Gray said the company has a better idea of the size of the plume of contaminated soil surrounding the leak site, but she did not have the details available to her on Friday.

She said the company’s crews had excavated much of the soil surrounding the leak site and believes it has gotten most of the contamination out of the ground, though she did not have the exact details of that work available to her on Friday …
