Critics say a ban would violate the state's voter-approved legalization of recreational marijuana, which took effect in January.
The EPA has granted more than 1,500 permits to energy and mining companies to inject dangerous pollutants into aquifers across some of the driest parts of the U.S. Some scientists and environmentalists say we’re going to need that water to drink and grow crops.
ProPublica reporter Abram Lustgarten says the permits are exemptions to the Safe Drinking Water Act, and are based on an old ruling, which says companies can pollute water that is too deep or too difficult to purify for drinking purposes.
But in at least 100 recorded cases, the permits have been granted to pollute aquifers that people are drawing on for drinking water. In other cases, the pollution has seeped beyond their original underground storage areas.
With new technology making it affordable to drill for water that was once thought too deep to use, states are being forced to choose between income today (for mining energy resources) and drinking water tomorrow.
