NEWS! Island County Well Data is now available via an Online Well-Viewer Application! With this application you can view wells in an area. Clicking on any well provides a link to more information about the well, including scanned well logs, water level, water quality (chemistry) and public water system information (where applicable and available). Where sufficient data exists, time-series plots of chemistry and water levels are also available.
MORE NEWS! A second new groundwater data mapping application provides site-specific spatial analysis of groundwater conditions. More information about the spatial analysis data products can be found HERE. To use the Groundwater Spatial Analysis Application, provide your name, e-mail address, and select the location of where you would like your groundwater spatial analysis to be centered. This application only contains information regarding wells located in Island County. Picking a location outside of Island County will not return results. If you are looking to site a new well, picking a location close to your proposed well location will allow this application to more accurately estimate the elevation of your proposed location. This will provide better estimates of drilling depth to reach aquifer elevations. Please allow 20 minutes after submission for an e-mail containing documents that summarize location-specific groundwater data analysis. In some cases, requests may not be filled until the next business day. Note: this application is in beta testing, please feel free to provide feedback!
The Hydrogeology program works to understand the complex groundwater system that serves as the primary source of drinking water for county residents. This understanding is accomplished by evaluating rainfall, water well and groundwater chemistry data using computer models and other analysis tools. Additionally, all land-use projects that have a potential to impact the quality or quantity of groundwater are reviewed to ensure the protection of clean, reliable sources of drinking water for all residents of Island County. Staff also serve as data stewards for the significant number of requests received from state and local agencies and community members. Education is a key component of the Hydrogeology program.
Program outcomes include protection of drinking water sources from potential intrusion of seawater, protection of drinking water sources from potential contamination, and sound groundwater resource management. 72% of all Island County residents rely upon groundwater as a drinking water source. All county residents share the responsibility to keep our groundwater resources safe.
