dont bite my head off. please., page-25

g'day shane,

we have always been aware of the potential for contamination of the water table.

this is one of the reasons a trial burn is conducted.

it obviously is news to some on here and the spooks will be out in their droves but their was NO contamination in the 3 years that the chinchilla trial burn lasted.

the instances of ground water contamination at the 5 sites you mentioned in another thread are possibly from locations where the coal was not at sufficient depth below the water table.

SO....thanks to all the "gloom" merchants but nothing is new and it is a fine example of fear mongering from those with an alternate agenda.

and note the last paragraph

This knowledge greatly benefited the Chinchilla project. “Chinchilla is an excellent example of how to plan a site and operate a UCG plant,” says Friedmann. “The operators maintained negative pressure in the combustion cavity so that contaminants could not flow beyond the cavity.”

here's an extract from an article about ucg,

Since these problematic tests in the 1970s, environmental scientists have learned a great deal about the behavior and types of contaminant compounds produced by UCG as well as about contaminant transport and environmental risk assessment. Several steps can be taken to avoid groundwater pollution. One is balancing operating conditions to minimize the transport of contaminants from overpressurized burn zones. Another is to locate a UCG site where natural geologic seals isolate the burn zone from surrounding strata. Isolating the site from current or future groundwater sources and understanding how UCG affects the local hydrogeology are essential. This knowledge greatly benefited the Chinchilla project. “Chinchilla is an excellent example of how to plan a site and operate a UCG plant,” says Friedmann. “The operators maintained negative pressure in the combustion cavity so that contaminants could not flow beyond the cavity.”
