LA Department of Environmental Quality continues sampling efforts in Bayou Corne area and LEAN develops Odor and Symptom Log for residents.
The Louisiana Department of Environmental Quality(LA DEQ) continues to perform air sampling in the Bayou Corne area. The samples collected by LA DEQ can be viewed on their website, here. The Environmental Protection Agency(EPA) utilized their plane to conduct monitoring by air last week but results were reported as non-detect. In response to the community concerns and potential threats from this situation, LEAN has developed an Odor and Symptom Log for the residents in the Bayou Corne area. This Log is tool for the community to monitor potential exposure and related health symptoms. The Log can be seen here.
In an article Thursday, Aug 23, 2012, the Advocate noted LEAN’s efforts to monitor the situation and assist the local community as this incident progresses. Some excerpts from this article are below:
…the Louisiana Environmental Action Network, a Baton Rouge environmental group, has asked Bayou Corne-area residents to log odors and any health symptoms that they feel as a result of the odors.
In two statements released Tuesday, LEAN noted air monitoring by the Louisiana Department of Environmental Quality since Aug. 4 over the sinkhole and in the neighborhoods near the sinkhole had picked up, depending on the location, benzene, toluene, ethylbenzene, other volatile organic compounds and components of natural gas.
Benzene is a known carcinogen.
LEAN also said the levels of those chemicals are below Louisiana ambient air standards, which mark a threshold for health risks.
Louisiana has set Ambient Air Standards for many toxic chemicals that could pose a threat to human health. To date, the air samples collected by LA DEQ in the Bayou Corne area have not exceeded any of the Louisiana Ambient Air Standards. Below is a chart showing some of the compounds detected in the Bayou Corne air samples on Aug 19, 2012 and their corresponding Louisiana Ambient Air Standard.

More from the Aug 23 2012 Advocate article:
LEAN group is concerned about the cumulative impact of all the chemicals in air together over time and developed the odor and symptom log as a way to track it, according to Wilma Subra, an environmental chemist who provides technical assistance to LEAN.
She said residents have already reported headaches and respiratory problems.
Copies of the log form are available at http://leanweb.org/odor-and-symptom-log. They can also be printed and mailed to:
