Over the past year, five states have begun requiring energy companies to disclose some of the chemicals they pump into the ground to extract oil and gas using the process of hydraulic fracturing.

While state regulators and the drilling industry say the rules should help resolve concerns about the safety of drilling, critics and some toxicologists say the requirements fall short of what’s needed to fully understand the risks to public health and the environment.

The regulations allow companies to keep proprietary chemicals secret from the public and, in some states, from regulators. Though most of the states require companies to report the volume and concentration of different drilling products, no state asks for the amounts of all the ingredients, a gap that some say is disturbing.

“It’s a shell game,” said Theo Colborn, a toxicologist who has testified before Congress about the dangers of drilling chemicals. Colborn and her organization, TEDX, examine the long-term health risks of chemicals and have opposed the expansion of drilling in Colorado and elsewhere. “They’re not telling you everything that there is to know.”
