City of Olympia
Behavior Barriers Research
The City of Olympia found increasing levels of nitrates in its groundwater, especially at a location designated the Shana Park Well #11 drinking water protection area. It was determined that lawn fertilizers contributed significantly to the rising nitrate levels. The city wanted to identify how to motivate residents to change their lawn fertilizer practices, and use this information to develop a community-based social marketing plan that would achieve groundwater protection goals outlined in the cityâ€™s 2009 Water System Plan.
