| Study Type | General environmental study |
| Study Purpose | A proposal has been developed to excavate and re-grade a portion of Little Squalicum Park in Bellingham, WA. The purpose of this project is to create an estuarine embayment, a key habitat enhancement for Little Squalicum Creek and Bellingham Bay. On the basis of previous observations of contamination within and upgradient of the estuary footprint, the Washington State Department of Ecology conducted a subsurface investigation of soil and groundwater contaminant conditions. Four of 20 soil samples collected from above the future estuary surface showed elevated concentrations of diesel- and lube-oil-range petroleum products. No organic contaminants were detected in groundwater. None of the soil samples collected below the future estuary surface showed organic or inorganic contaminant concentrations above Washington State Sediment Management Standards marine sediment chemical criteria. |

| Study QA Project Plan Description | The goal of the project described in this work plan is to conduct reconnaissance sampling and mapping of soil and groundwater conditions within and beneath the proposed estuary excavation in order to better characterize the presence and extent of chemical contamination. Sampling will be conducted using direct-push drilling techniques. It will focus on characterizing conditions both above and immediately below the design topographic surface of the proposed estuary. This information will help interested stakeholders judge the feasibility and potential costs of the estuary project, and determine if soils excavated during construction of the estuary are likely to require special handling and disposal. |
