Study: Increase in cannabis cultivation or residential development could impact water resources
Researchers in Canada and the U.S. investigated potential reductions in streamflow, caused by groundwater pumping for cannabis irrigation, in the Navarro River in Mendocino County, California… Reporting in the journal Environmental Research Communications, they note the combination of cannabis cultivation and residential use may cause significant streamflow depletion, with the largest impacts in late summer when streams and local fish species depend most on groundwater inflows.
