Groundwater Protection
The key to protecting groundwater is proper well
construction, and the oil and gas industry has developed
detailed standards for this based on field experience
and significant advances in drilling and construction
techniques. In fact, there have been no confirmed cases
of groundwater contamination from hydraulic fracturing
itself in the at least 2 million wells fracked over the past
68 years.11
A typical natural gas well uses 3 million pounds of steel
and cement. Each layer of steel casing is cemented
in place to create an air-tight seal. Alternating layers
of cement and steel casings are designed to ensure
well integrity as it passes through groundwater levels
thousands of feet down to the energy-holding layers
of rock.
