"FORT WORTH — Texans pride themselves on being the heart of the nation’s oil and gas business. But even here, public concern about natural gas drilling is growing.

On Wednesday, several dozen protesters marched through downtown Fort Worth, waving signs and chanting anti-drilling slogans that reflected concern over air and water pollution.

The anxiety centers on a recently expanded drilling method called hydraulic fracturing, or fracking, which is now used in more than half of new gas wells drilled in Texas. This practice — which involves blasting water, sand and chemicals far underground to break up rock and extract gas — is common in the Barnett Shale, a major shale-gas field around Fort Worth."
