PITTSBURGH (AP) -- Is gas drilling ruining the air, polluting water, and making people sick? Scientists say the evidence is sketchy and inconclusive, but a lack of serious funding is delaying efforts to resolve the pressing questions.
Bernard Goldstein, professor emeritus at the University of Pittsburgh School of Public Health, says the kind of comprehensive research that's needed "just hasn't started."
The Environmental Defense Fund says it is partnering with major universities and eight natural gas companies on ways to address environmental and health concerns, but it hasn't provided details.
Experts including Goldstein say the lack of research could lead to a crush of lawsuits and expensive settlements for the industry.
