The temporary chain-link fences are down and new trees have been planted, but nothing much seems to be going on at Denver's City Park Duck Lake. The scene of many previous duck die-offs, work on the $1.6 million rehab and excavation of the bottom sediment was halted in early November, 2010, by OSHA (Occupational Safety and Health Administration) after a complaint regarding worker safety was filed. Testing is said to be underway, but no new information has been forthcoming.
Water containing 157 pollutants and 10 radionuclides from the Lowry Landfill Superfund Site makes its way into Duck Lake by way of the Denver Ditch at Washington Park's Grasmere Lake, where "purple pipe water" from the recycling plant is discharged. Go here and here for more information.
