Water for Pot No Longer Unregulated

Within less than a year, as many as 50,000 marijuana growers in California could be required to obtain state permits for the irrigation water they consume. It is an unprecedented step aimed at preventing harm to the environment and other water users resulting from the rapid growth of marijuana cultivation in the state.

“Most of them are operating below the radar,” said Cris Carrigan, chief of enforcement at the State Water Resources Control Board. “As a result, we’ve gotten ourselves into an acute problem with streamflow and pollution associated with these activities.”
