Oil companies that blast water and chemicals into the earth to extract fossil fuels are having trouble getting new permits for their California operations even sooner than expected. Gov. Gavin Newsom pledged the state would stop issuing new permits for fracking by 2024, but California has already begun to ban the controversial oil extraction method in practice by denying permits in droves with little fanfare. … [Fracking has] long been a controversial method because of what climate activists see as unacceptable dangers, including the possibility that it can contaminate groundwater.

In a bid to address these problems, on at least a small scale, the city of Los Angeles and several local partners have teamed up on a novel approach.

Thus, even if these impacts were perhaps unbeknownst to the majority of Californians who approved Proposition 64 in 2016, we thought it important to see if anything new had evolved from a water perspective now that marijuana was legal.
