As the cannabis industry grows and legalization expands, the impacts of wastewater generated from cannabis processing requires research that can inform cannabis wastewater regulation under development. As of September 2019, 11 US states had legalized cannabis completely and 10 have legalized medical cannabis and decriminalized cannabis use. Many more states have legalized medical cannabis. In only eight states is marijuana still fully illegal.
Wastewater areas of concern and focus vary by the type of facility. Growers, processors, end-product manufacturers, and potentially entertainment venues all have treatment needs but they are different.
Wastewater solutions vary depending on the state and currently there is no specific regulation surrounding onsite wastewater treatment systems and the allowance of cannabis wastewater. Some facilities are recycling wastewater for a zero discharge, while other industrial scale facilities are employing collect, store, haul strategies like agricultural and pharmaceutical hazardous waste practices. Local municipalities and regulatory authorities are working to develop individualized plans for disposal and/or pretreatment base on the type of facility.
There is still in sufficient data available on wastewater characterization and that data is key to developing policy and procedure best practices for cannabis wastewater collection and treatment. Another challenge is that state and federal law is not aligned hampering broad best practice development that can be implemented across the US.
