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. If you are looking for well information for a few wells in an area, this is the easiest way to get that information. If you want to gain an understanding of a groundwater conditions over a wider area, the application described in the following section may be more useful:
MORE NEWS! A second new groundwater data mapping application provides site-specific spatial analysis of groundwater conditions around a user-specified location. 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. Note: this application is in beta testing, please feel free to provide feedback!
Island County Public Health downloads and processes precipitation data from the Western Regional Climate Center for selected precipitation stations in and around Island County. A google earth map displaying these station locations and providing links to plots can be found HERE. Planning a wedding or other outdoor event? Check out the Monthly Average Plot for the station nearest your event to find out which months have the lowest average precipitation (YMMV).
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 nearly 9000 wells. The public can access Island County groundwater data through either the Online Well-Viewer Application or the Groundwater Spatial Analysis Application.
The following standard data products are available for any given spatial analysis search (click on the name to view an example of each):
In addition to the bottom-hole elevation analysis, the TdDist report also provides evaluations of
vertical distribution of major contaminants of
concern (arsenic, chloride, hardness and
nitrate) vs elevation / depth. A separate plot
(page in the pdf document) is provided for
each chemical / analyte.
