Stormwater from a small municipality in Utah was monitored for flow and phosphorus. A survey was also administered to ascertain potential behavioral impacts on stormwater. The majority (53.7%) of stormwater measured was non-storm related. It is suspected that summer irrigation was adding to baseflow. Concentrations of phosphorus were below national means, but were high enough to lead to excessive algal growth. Survey results showed that most residents (92.3%) fertilize their lawn, although very few (1.7%) use a soil test to determine if fertilization is necessary. The study highlights the need for monitoring, surveying and collaboration to address current stormwater issues.
