"The Environmental Protection Agency announced on Monday that it would overhaul drinking water regulations so that officials could police dozens of contaminants simultaneously and tighten rules on the chemicals used by industries.
The new policies, which are still being drawn up, will probably force some local water systems to use more effective cleaning technologies, but may raise water rates.
“There are a range of chemicals that have become more prevalent in our products, our water and our bodies in the last 50 years,” the E.P.A. administrator, Lisa P. Jackson, said in a speech on Monday. Regulations have not kept pace with scientific discoveries, and so the agency is issuing “a new vision for providing clean, safe drinking water.”
Along with its other steps, Ms. Jackson said the E.P.A. was readying stricter regulations on four carcinogens often detected in drinking water, including a chemical commonly used in dry cleaning."
