Recently I asked to have my email address added to Todd Hartman’s COGCC email update list which goes out to members of the media. I received no reply and I have not received the latest updates. If they are so concerned about accurate reporting you might think they would want me to have the most up-to-date information. Perhaps they are more concerned with controlling the flow of information.

So how do I get my hands on these updates anyway? I’ll never tell …

COGCC update – April 15, 2013

Here is an update on the situation at the Parachute Creek gas facility from information gathered over the weekend.

Two new monitoring wells on the south side of Parachute Creek detected benzene at 490 and 520 parts per billion. However, a series of five more monitoring wells continuing downstream on both sides of the creek did not detect benzene. This suggests the extent of impacted groundwater is beginning to take shape.

Operators pumping from new recovery trenches on the north side of the creek and completed late last week captured 78 barrels of water and 96 gallons (a little more than two barrels) of hydrocarbons. This brings the total of hydrocarbon liquids collected sitewide to about 144 barrels.

The latest surface water sampling results did not show any contamination at any monitoring points, including at the point 2.7 miles downstream of the investigation area, where the town of Parachute diverts water to its irrigation reservoir.

Newly accumulated water level data from additional monitoring wells and stream gauges continues to indicate Parachute Creek is a losing stream throughout the area investigated and sampled.

The COGCC remains in close communication with the Colorado Department of Public Health and Environment and the U.S. Environmental Protection Agency about this situation.

Note: One media report over the weekend* indicated that the town of Parachute uses the water diverted for irrigation for its drinking water supply. The town administrator has reiterated today (April 15) that this is not the case.
