October 2000 the NRDC study assesses the growing controversy over an aquifer under the Black Mesa plateau in Arizona and concludes that the aquifer is showing signs of serious decline after years of pumping by the Peabody Western Coal Company, which drains more than a billion gallons of water from the reservoir each year to transport coal. NRDC also considers the role of the federal government in resolving the problem, and recommends actions that would help conserve Black Mesa's water supply.
