Lummi Peninsula groundwater settlement agreement

All new wells or new connections to existing wells must have a meter installed prior to any beneficial use of water. Each homeowner must install their own meter on the water line serving only their residence.

There are specific requirements regarding the type of meter you install and how you need to install it:

• Meter Installations on the Lummi Peninsula

The settlement agreement requires all state water users to sample their well water for chloride. This publication provides information on who, where, why, when, and how the chloride sampling is to occur:

Chloride monitoring visits

As a part of Section V.H.3 of the Lummi Peninsula settlement agreement, we and the Lummi Nation annually conduct monitoring visits (“spot checks”) of all state- and Lummi-regulated wells in the case area. At a minimum, all supply wells and 10 percent of all small wells are spot checked. Monitoring visits include either observing the state water user perform their chloride sampling or having us and/or the Lummi Nation collect a chloride sample.

Small wells

Small wells includes all wells, regardless of size, developed or used to withdraw one to three allocations of 0.39 acre-feet per year from our allocation under the settlement agreement.
