Drinking Water Lab


The Health Department is currently testing drinking water for bacteria and nitrates. Nitrate samples can only be tested from private water supplies.

Standards for Water Availability Verification (WAV) are applicable to building permit applications for new structures requiring a source of potable water. They are not applicable to additions within the existing structure, remodels, or structures with no plumbing. 

If you need to test for additional analytes like arsenic, lead, copper, or iron, you may click the link below for additional labs.
