Please note: The partial and
complete mineral analyses require a sample of at least one liter in a clean
plastic or glass container. Do not use a plastic container which has held substances such
as bleach, soap or vinegar as the sample could potentially become contaminated. A plastic
distilled water container is best. Do not use a metal container or a container
with a metal lid.
The mineral analysis will identify dissolved
minerals in the water supply. Some of the constituents may pose a health risk while others
affect the suitability for washing or other household uses. Mineral constituents will
generally be reported as mg/L which is essentially equivalent to parts per million.
Special or unusual requests can possibly be
handled and will have a varying price range. Please call for details [701-328-6140] or

Laboratories that analyze water samples from North Dakota public water systems to
determine compliance with requirements of the Safe Drinking Water Act must be
certified by the North Dakota Department of Health. Laboratories that provide certain
other environmental data for use by the Department must have valid certification. Please
refer to the
for more information.
When submitting samples: Please
include your name, address and telephone number. Also include the date the sample was
collected and the following demographic information if it is available: The source of the
sample (well, stock pond, tap water, etc.) and its use. If it is from a well, please
include the county, township, range and section data. Be sure to include the
requested. Send the samples to the North
Dakota Department of Environmental Quality, PO Box 5573, Bismarck, ND 58506. These analyses
generally take approximately two weeks to complete and mail out but on occasion may take
longer due to heavy sample load and/or program priority.
If you have any questions please call 701-328-6140.
