To order bottles and mailers for your county, contact the Environmental Health Office at 406-258-4755.  We can only provide sample bottles to locations within the 598__ zip code range.  The US Postal Service cannot guarantee next day delivery outside that zip code range.

Water samples must be received by the lab for analysis within 36 hours of being drawn.  Samples older than 40 hours cannot be considered valid samples.  For public water supplies, the state will not accept water sample results from samples more than 40 hours old.
