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 8000 wells. For security reasons, data is only available by request. Requests for groundwater data can be made by contacting the Island County Hydrogeologist.
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):
