Abstract

Existing policies regulating nonpoint source water pollution in California and beyond are difficult to
enforce due to ineffective monitoring and gaps in available data. We propose a method that generates
a more spatially and temporally resolved dataset to help identify sources of nitrogen and phosphorus
pollution, with applications to the U.S. Mississippi River Basin and the country of New Zealand.

Keywords

Agricultural runoff, regulatory enforcement, spatial analysis, nutrient loads
