This report summarizes the in-progress findings (2009‒2017) of surface water chemistry within the Puget Sound Naval Shipyard & Intermediate Maintenance Facility (PSNS & IMF, part of Naval Base Kitsap- Bremerton [NBK]), and surrounding marine waters (Sinclair and Dyes Inlets), collected under Project ENVironmental inVESTment’s (ENVVEST’s) Ambient Monitoring Program. Project ENVVEST was initiated as a cooperative effort among the NBK, regulatory agencies, and local stakeholders to protect beneficial uses of Sinclair and Dyes Inlets. The overall goal of the Ambient Monitoring Program, under Project ENVVEST, is monitoring and tracking environmental water quality to support characterization of the status and trends of ecological resources, assess the effectiveness of cleanup and pollution control measures, and determine whether discharges from all sources are protective of beneficial uses, including those related to aquatic life and human health, in the receiving waters of the Inlets—all in the context of U.S. Environmental Protection Agency (EPA) National Pollution Discharge and Elimination System (NPDES) regulations, Comprehensive Environmental Response, Compensation, and Liability Act cleanup requirements, and EPA aquatic life criteria. This report is provided by the Pacific Northwest National Laboratory’s (PNNL’s) Marine Science Laboratory (MSL). MSL has been instrumental in designing the field sampling programs for biota, sediments, stormwater, and marine water for Project ENVVEST, and providing chemical analyses of metals and organics at the required low levels of detection to meet Project goals.
