Public Health Water Lab Changes Sample Bottle Procedures

The Lewis County Public Health & Social Services (PHSS) water lab has resumed operations, but must change its public access procedures due to the county buildings closure orders. Until further notice, requests for sample bottles must be made by calling 360-740-1222. No requests for sample bottles will be accepted in-person at the Health Department building in downtown Chehalis at this time. Click here for more information.

The Lewis County Water Lab is certified to analyze coliform bacteria and nitrate samples. These are the most commonly tested parameters for public water supplies and are also required for individuals on private wells obtaining building permits.

Each test costs $28 and must be submitted in a specially treated sample bottle.

Sample bottles may be picked up on the 3rd floor of the Health Department at 360 NW North Street (map it), Monday-Friday 8:00-11:30am and 12:30-4:30pm.

Coliform bacteria samples may be submitted at the Health Department Monday-Wednesday, 8:00-11:30am and 12:30-4:30pm.

Nitrate samples may be submitted on Mondays or Tuesdays only.

Samples should be submitted the same day they are collected and must be kept cool. We also have several sites throughout the county where samples may be dropped off.

Pick-up will be the first Monday every month before 9:30 am:

  • Silver Creek Post Office
  • Morton City Hall
  • Randle Post Office
