Large-scale, centralized livestock production is recognized as a significant contributor to environmental pollution, including groundwater contamination. Here we assess the impact of traditional meat production on nitrate contamination in groundwater across the contiguous USA from 1985 to 2020. In addition, we evaluate potential changes in groundwater quality resulting from the substitution of traditional meat sources with three alternative meat…
