Notes:

Island County Code 8.09.099 (Seawater Intrusion Protection) is designed to help protect our aquifers / drinking water from issues related to seawater intrusion. One of the tools incorporated into the code is the development of seawater intrusion risk ratings for areas of the county. Areas are classified as being either 'low', 'medium', 'high', or 'very high' risk for seawater intrusion based on water level elevation and chloride concentration data from all wells located within 1/2 mile of the point in question. Public water system (3 or more connections) sources that are classified as having elevated seawater intrusion risk (medium, high, or very-high) are required to monitor water quality in those sources.

When monitoring of a well is required under ICC 8.09.099, the well should be sampled twice per year, during the months of April and August. Samples should be submitted to a state-certified laboratory, and analyzed for chloride and electrical conductivity. Samples should be collected from each elevated risk source (well), not combined wellfield sources. Samples should be labeled as 'compliance' and the water system ID (PwsID) and source number must be included so that the sample results can be credited to your system / well.

An SWI Rating of "ND" means there is insufficient data available to calculate a rating at this location. Monitoring is not required in this situation (Monitoring Required = "No"). If however Monitoring Required = "No*" then based on available information, ICPH recommends that monitoring be conducted (although it is not required).

If you'd like to review the water quality data we have on file for any given well, click on that wells 'Well Key' (3-digit code). A report will open pertaining to that well. Look down for the 'Water Quality Information' section, and then click on the bright blue text that indicates the number of water samples for the well.
