Benzene level drops

PARACHUTE — The concentration of benzene at a particular point on Parachute creek dropped by an appreciable amount on May 2, according to a report from the Colorado Department of Public Health and Environment (CDPHE).

The level detected on May 2 was 4.7 parts per billion (ppb), down from the level of 5.3 ppb detected on May 1, the CDPHE reported on Friday.

The levels reported are well below the standard for benzene in non-drinking-water sources, which is 5,300 ppb.

But the levels detected have been right around the allowable level of benzene in drinking water, which is 5 ppb.

Parachute Creek is considered a non-drinking-water source by state and federal agencies.
