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. To use this application, provide your name, e-mail address, and select the location of where you would like your groundwater spatial analysis to be centered. 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. The groundwater spatial analysis mapping application can be found HERE. This application is in beta testing, please feel free to provide feedback!
Finally, the Island County Seawater Intrusion Risk map is available HERE.
The hydrogeology program maintains a groundwater database containing information regarding well construction, stratigraphy, groundwater quality (chemistry) and water level data. Currently the database contains information from over 8000 wells. You can contact us to make requests for detailed site-specific data and analysis, or to provide information regarding data errors or omissions.
The most common data request involves specifying a search center (typically a parcel or a well) and a search radius (1/2 mile radius is common). The following standard data products are available for any given search (click on the name to view an example of each):
