Lake Forest Park Water District provides drinking water to about 2700 residents in the City of Lake Forest Park.

As part of the District's ongoing source water protection, a Critical Aquifer Recharge Areas (CARA) Report has been completed and is available here: Critical Aquifer Recharge Areas Report Available 

The CARA delineation is in both King and Snohomish Counties, encompasses Cities of Brier and Lake Forest Park and provides a hydrogeological overview that can be used to provide additional protection of the District's exceptional water quality.

Associated Earth Sciences Inc. was commissioned to produce a report that characterizes the LFPWD source aquifer, inventories existing and potential sources of contamination, analyzes susceptibility , provides additional mapping and GIS data, designates areas of potential contamination.

The report was done in collaboration with North Seattle College (NSC) geology students in a soil analysis project to study superficial geology.

The findings of AESI were presented in a public meeting on August 22 at the Brier city hall.

As per WA DOH, "The Growth Management Act requires protection of public groundwater drinking supplies so that tragic events and their associated costs can be prevented and groundwater availability is not compromised. The prevention of groundwater contamination is far less expensive than cleanup or treatment." 

The CARA study was made possible through a grant from WA Department of Health, office of Safe Drinking Water/Source Water Protection and the Environmental Protection Agency.

Lake Forest Park Water District serves water to 897 connections within the City of Lake Forest Park with pure, unchlorinated well water from 8 artesian wells and 5 deep wells from the McKinnon Creek and Horizon View wellfields.
