One community group is reaching as far as it can to spread warnings about coal seam gas extraction.

The Limestone Coast Protection Alliance says it will distribute over 10,000 flyers opposing unconventional gas exploration in South Australia.

Residences were bombarded with the pamphlet this week, which outlined the Alliance’s concerns about the “gas fracking” exploration techniques

They say the risk of groundwater contamination is the most present, but also only the start of the worries.

“For us in the Limestone Coast we rely solely on this precious resource which [is] our water,” Limestone Coast Protection Alliance spokesperson Sue Westgarth has told the ABC.

“If that was to be contaminated it would actually affect everybody, whether you live on a farm, in a community or in the town.”

The informational pamphlet was created and paid for by the alliance, which also holds film nights to raise money.

“We do have donations on the evenings, we also have merchandise that we sell to raise funds and we do have the Lock the Gate signs which we have now sold approximately 2,000 of them,” Ms Westgarth said.

The Limestone Coast Alliance defends its area of south-east South Australia against a broad range of environmental risks.

The toxic chemical components used hydraulic fracturing for coal are a major concern, along with air and soil health, food security and landholders rights over mining exploration.
