Farley is developing a project that seeks to better understand how conflicts develop over proposed oil and gas extraction sites in rural North America by investigating rural residents' perceptions of the nature and the purpose of agricultural and industrialized landscapes.
This scenario assumes that all those under consideration go on to be fully operational shale gas extraction sites.
These show that chemicals, including methane and arsenic, have been found more often in water wells near natural gas extraction sites.
In common with the Texas study, the Duke researchers found that water wells closer to gas extraction sites had higher levels of methane.
For new and modified oil and gas extraction sites, the EPA has set new standards for reducing emissions that the agency says will capture 510,000 short tons of methane in 2025 -- the equivalent of 11 million metric tons of CO2.
Four anti-fracking protesters have been arrested as they tried to stop a lorry delivering machinery to a potential methane-gas extraction site in Salford, Greater Manchester.
Mr Smith said that "potential shale-gas extraction sites cover most of the UK and operate at depths of about 4,000 feet, so there should be no impact whatsoever on mortgage lending, home insurance or anything connected to such issues".
When he and his colleagues recently investigated the potential health risks of hydraulic fracturing, they discovered that skin problems were common in both the people and the dogs living near gas-extraction sites.
Communities Secretary Sajid Javid approved plans for shale gas extraction at Cuadrilla's Preston New Road site at Little Plumpton in October 2016.
She works at the state, national and international levels on a range of issues including: ocean governance, Coastal and Marine Spatial Planning, offshore oil and gas exploration and extraction, siting of ocean renewable energy, marine protected areas, and ocean pollution, particularly from land-based sources.
Protests have been held at the Little Plumpton site since shale gas extraction was approved in 2016.
