| Study Name | Hangman Hills Sewage Treatment Plant Nutrient Loading and Groundwater Study |
| EIM Data Entry Review Status | Reviewed |
| Study Type | General environmental study |
| Study Purpose | The goal of this project is to determine which sources of nitrogen and phosphorus are infiltrating to groundwater and migrating into Hangman Creek. The primary focus of this study is to quantify the nutrient load from the Hangman Hills Sewage Treatment Plant into the creek. Secondarily, this project will attempt to identify gaining and losing reaches of the lower creek where there are transitions in land use. This project will also attempt to quantify the nutrient load from the golf course and agricultural sources.The Washington State Department of Ecology (Ecology) will collect water quality samples from existing groundwater wells, groundwater seeps, and surface water sites. |
