During times of drought and wildfires, the Australian company Santos is pushing a project that is putting eastern Australia’s vital water resources at risk.[1] Santos wants to produce fossil gas from coalbeds deep within the earth.[2] Its Narrabri project is a threat to the water and all those who depend on it: the indigenous Gomeroi people, local farmers, residents, and the Pilliga forest.[3]

In the Narrabri project, Santos wants to produce coalbed methane (CBM), an unconventional form of fossil gas. CBM is stored in underground coalbeds at depths of hundreds of meters.[4] Pressurized water inside the coal seams holds the methane in place.[5] To extract the gas from the depths of the earth, Santos must pump the water out of the coalbed to reduce the pressure.[6][7] This allows the gas to flow to the surface.[8]

In the Narrabri project area, Santos is preparing to drill 850 gas wells spread over 95,000 hectares (950 km2).[9] In November 2020, the federal Australian government gave Santos the green light for its Narrabri project.[10] The company has not yet made a final investment decision or started production.[11] But governmental authorities already support Santos’ Narrabri CBM project and its potential future expansion to more than 10,000 wells spread across 1,000,000 hectares (10,000 km2).[12][13]

When Santos fiddles with water, it plays with fire. The coalbeds that Santos wants to drill into lie underneath the Great Artesian Basin (GAB).[14] The GAB is Australia’s largest groundwater reserve.[15] The basin and connected water reservoirs are a life support system for hundreds of thousands of people in Australia.[16] If Santos removes gas and water from deep layers, overlying groundwater may sink deeper into the ground.[17] It could subside to depths that people’s wells can no longer reach.[18] Without access to the abundant and clean water of the GAB, people in eastern and central Australia could not farm or sustain their livestock, and ecosystems would not survive.[19]

At the same time, Santos puts the clean and abundant water of the GAB at risk of pollution. If the Narrabri project goes ahead, the company could pump up to 37.5 billion liters (9.9 billion gallons) of water out of the coal seams.[20] This water is extremely salty and contains heavy metals and radioactive elements.[21] Spills and leaks of this wastewater are inevitable.[22] Already during the exploration phase of the Narrabri project, Santos polluted an aquifer with wastewater that contained uranium, a radioactive and toxic element.[23] If Santos filters all its wastewater, it would produce up to 840,000 tonnes of toxic salty waste.[24] So far, Santos has no clear plans what to do with this waste.[25] One of its ideas is to dump the salty waste into landfills, where it could dissolve and seep into the groundwater.[26][27]

A large part of Santos’ Narrabri CBM project lies in the heart of the iconic Pilliga Forest.[28] The Pilliga Forest stretches over half a million hectares of rare eucalypt woodland and white cypress pine.[29][30] Numerous endangered animals such as squirrel gliders, barking owls, koalas, black-striped wallabies and the Pilliga mouse live in the forest.[31] It is a biodiversity oasis inside an otherwise agricultural landscape.[32] If the project goes ahead, Santos will cut down parts of the Pilliga Forest.[33] It will bulldoze the soil to build well sites, pipelines, and roads in the forest.[34] The Pilliga mouse, koalas and other animals will have to find new habitats to live in.[35]

Like a heartbeat, the Pilliga forest pumps rain and surface water into the soil and the GAB.[36] Whatever Santos spills in the forest could spread through the underground water system, where it cannot be removed.[37][38] In the depths of the Pilliga Forest, Santos has already spilled polluted wastewater 20 times.[39] The wastewater seeped into the groundwater, poisoned the soil and killed the plants.[40] Until today, Santos has not been able to bring these death zones in the Pilliga forest back to life.[41]

When Santos invades the Pilliga Forest, it is stepping into the homeland of the Gomeroi people, an indigenous First Nation.[42] For centuries, the Gomeroi have been guarding the waters in and beneath the surface of the Pilliga Forest.[43] Now, they must protect it from Santos’ Narrabri project – a project they have never agreed to.[44] On December 3rd, 2020, indigenous protestors rallied in Sydney, Melbourne, Canberra and Brisbane on a national day of action against the project.[45] Gomeroi woman Polly Cutmore made clear that “Our people don’t want this gasfield and we are here to tell the Government, Santos and their investors that we will keep on fighting it."[46]

The Gomeroi are not alone in their resistance against the Narrabri project. In 2017, regulatory authorities received a record number of more than 22,000 objections against the development of the project.[47] A shareholder activist group is now also taking Santos to court for greenwashing and misleading statements.[48] Santos will have to defend its claims that its gas business would produce “clean fuels”.[49] Santos’ Narrabri project is not a done deal. Farmers, community members, the Gomeroi and activists continue to fight to protect the land, the forest and their most valuable resource: water.
