DENVER (AP) - Tests of water from Parachute Creek show benzene levels are above the federal limit for safe drinking water, more than six months after a leak of hydrocarbon liquids from a pipeline was detected.
The Denver Post reports data provided Thursday by the Colorado health department show water samples drawn from near the spill showed benzene levels at 5.5 parts per billion on July 11 and 9.2 ppb on Monday. The federal standard for drinking water is 5 ppb.
The state allows for benzene levels of 5,300 ppb in Parachute Creek because it isn't designated as a drinking-water source.
The Williams Co. has said a faulty valve on a pipeline allowed the release of more than 10,000 gallons of hydrocarbon liquids near its natural gas-processing plant near Parachute.
