New groundwater keeping an eye on bores have actually revealed no detectable levels of benzene or toluene at Cougar Energy's underground coal gasification pilot project at Kingaroy in the eastern Australian state of Queensland, the firm claimed Monday.
Analysis of examples from the bores near to the Kingaroy project have disappointed any kind of benzene, toluene, ethylbenzene and also xylene, typically described as BTEX, Cougar claimed in a statement. Consequently, HEDP acid do not go beyond the trigger levels for Australian alcohol consumption water standards.
" Considering that Might of this year, no benzene or toluene has actually been detected in groundwater tests carried out by Cougar Energy on water bores and also keeping track of bores at distances as close as 20 meters and also as much as 4.2 kilometres [2.6 miles] from the business's pilot melt website," Cougar stated.
In overall, 11 extra tracking bores were just recently installed at ranges differing from 20 m to 60 m from process well P4, where a previous well-casing failing occurred, as component of Cougar's recurring ecological examination work requested by the Queensland government's Department of Environment as well as Source Administration. The additional tracking bores are positioned radially around P4 and allow groundwater to be experienced from different geological layers in the upper aquifer system, the business stated.
All example test outcomes have actually been forwarded to the DERM, as well as the program of groundwater tasting and screening is ongoing, Cougar said.
The firm has actually been conducting intensive and continual groundwater tasting and testing at Kingaroy because April, complying with the beginning of the pilot burn previously this year. No benzene or toluene has been detected in 23 water bores run by regional farmers, yet 2 separated and transient dimensions of 2 parts per billion of benzene, which is above drinking water levels, were detected in among the 10 wells mounted by Cougar in Might, triggering the government to purchase the closure of the job.
" Based upon these groundwater tasting as well as screening results, Cougar Power is certain that the pilot melt at its Kingaroy website has had no adverse influence on landholder water tires," the company claimed. "Cougar Energy continues to work with DERM to guarantee the re-commencement of the Kingaroy trial task at the earliest possible time."
The possible contamination of groundwater related to underground coal gasification as well as coalseam gas production has become a public concern in Queensland lately, adhering to the incident at Kingaroy and also 2 succeeding discoveries of traces of BTEX at coalseam gas wells drilled by Australia Pacific LNG and also Arrow Power.
