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
  • Packwood Post Office

The lab is closed and no samples will be accepted on government holidays.
