How does Lighthouse Shores compare with other water systems in Island County?
By EPA's size categories, Lighthouse Shores is a very small system (500 people or fewer). Island County has 307 active public water systems. Its population served is about half of the county average of 335 people per system, and accounts for 0.1% of the 102,977 people reported by systems filed under the county. Across Washington, the 4,705 active systems average 2,172 people each. Nationally, the average active community water system reports serving 6,703 people, so Lighthouse Shores is well below that figure.
What does “community water system” mean?

Homes, apartments and mobile-home parks are served by these. Washington has 2,392 active community water systems, 51% of the state's 4,705 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 4,370 Washington systems (93%) list groundwater as their primary source.

Does Lighthouse Shores have drinking water violations?
