No hazardous levels of contaminants found after EnCana truck spills

Soil and water samples taken from and around Mamm Creek after a truck spilled produced water show contaminant levels that meet state health standards. A truck carrying 6,750 gallons of water produced from EnCana natural gas wells in Hunter Mesa overturned at the intersection of County Roads 322 and 315 (Mamm Creek Road) Sunday, Feb. 5.The driver of a tractor-trailer owned by Arnett Trucking Co. lost control about 1:30 p.m. while ascending a hill. The tractor remained upright but the trailer rolled and spilled its contents into Mamm Creek. Samples were tested by Environmental Science Corp. of Mt. Juliet, Tenn. Soil samples, collected on the day of the spill and the following day, did reveal levels of hydrocarbons containing potentially toxic chemicals such as benzene, toluene, ethylbenzene and xylene at levels well below state clean-up standards. Traces of BTEX chemicals were also found in water samples, also easily meeting acceptable levels.”Results of the water and soil samples for the spill incident at Mamm Creek … show the contaminants to be well below the Colorado clean-up standards for surface soils in a residential area (the strictest standards) and also well below the maximum contaminant levels for drinking water,” said EnCana spokesman Doug Hock.Mamm Creek empties into the Colorado River just south and east of Rifle and upstream of Rifle’s municipal water intake.Contact Donna Gray: 945-8515, ext.
