Surface Water Emissions from Cannabis Cultivation Sites: Quantity, Quality, Toxicity, and Relationships to Farmers’ Practices

This project will survey cannabis and other crop growers for self-reported farm practices, analyze pesticide residue from local dispensary products versus other crops, and sample and analyze waters downstream of farms for quality and toxicity. The goal is to assess cannabis farming practices for their environmental effect.
