• Air Monitoring Sample Data
– 1 letter (dated 10/18/2012) was released to the parish during this operational period for community ambient air and air at bubble sites sampled 9/28/2012- 10/14/2012 (MultiRAE). Findings-It does not appear that chemical exposure of site-related contaminants poses a public health risk to individuals in the immediate area of Bayou Corne for the time period and chemicals sampled.
– 1 letter (dated 10/18/2012) was released to the parish during this operational period for residential ambient air sampled 9/28/2012-10/13/2012 (MultiRAE); Findings-It does not appear that chemical exposure of site-related contaminants poses a public health risk to individuals in the immediate area of Bayou Corne for the time period and chemicals sampled.
– 1 letter (dated 10/18/2012) was released to the parish during this operational period for air samples collected 9/26/2012 and 10/2/2012 (isotopic analysis); Findings-This data is meant to characterize the gas in the bubbles and wells sampled. These type of analyses do not provide data that could be used for assessing public health.
– SEET has received and is analyzing community ambient air sampled 10/15/2012- 11/4/2012 (MultiRAE). SEET will issue a letter to the parish in reference to these findings once the review of the data has been completed.
– SEET has received and is analyzing sample results for air at bubble sites collected 10/15/2012/2012-11/4/2012 (MultiRAE). SEET will issue a letter to the parish in reference to these findings once the review of the data has been completed.
• Industrial Water Well Sampling Data – 1 letter (dated 10/18/2012) was released to the parish during this operational period for industrial wells sampled on 9/26/2012. Findings-DHH recommends immediate remediation of industrial water wells with high levels of methane.
– Safe Drinking Water – 1 letter (dated 10/18/2012) was released to the parish during this operational period for two privately-owned water wells sampled on 9/26/2012. Findings-DHH recommends property owners routinely monitor for the presence of methane in the tested water wells.
– As of 06 November, Texas Brine has removed 123 roll off boxes hydrocarbon contaminated debris. – As of 06 November, Texas Brine has removed approximately 1535 Barrels of hydrocarbons from the surface of the sinkhole.
Next Operational Period (8-13 Nov 2012) Incident Action Plan
– Pursant to the DNR press release dated 11/7/2012 regarding the pressure in some geoprobes, LDEQ will conduct indoor air monitoring as requested at residential homes in the Bayou Corne community.
Texas Brine, LLC UPDATE November 8, 2012
1. The Observation Well is shut in today. A total depth measurement of the cavern floor was conducted today, the results of which will be reported on Friday. The controlled removal of liquid hydrocarbon from cavern #3 will be conducted on Friday as well.
2. There were no observable changes in the sinkhole’s characteristics. Only a minimal amount of liquid hydrocarbon now remains on the sinkhole surface. Skimming operations have been turned to the removal of hydrocarbon material from the surface of the shallow water in the treed areas on the sinkhole perimeter.
3. Flaring of natural gas from the shallow aquifer relief well continues on a 24- hour basis. As of 8:00 a.m. today, just over 100,000 cubic feet of natural gas has been vented from aquifer and safely flared at the surface.
