💧 Montana Homebuyers: Don’t Skip the Water Test! Here’s Why It Matter

In Big Sky Country, we enjoy pristine views, rugged landscapes—and often, private wells for water. But when it comes to buying a home in Montana, especially in rural areas, testing the water isn’t just smart—it’s essential.

If you’re buying (or selling) a home in Montana with a private well or spring, here’s what you need to know.


đźš° Why Water Testing Matters in Montana

Unlike homes on city water systems, rural properties often rely on private wells, which aren’t regulated by municipal testing. That means:

  • No one is checking the water quality unless you do.

  • You’re responsible for the health and safety of your drinking water.

  • Lending institutions may require testing as part of a mortgage.

Common Montana water issues include:

  • Nitrates and nitrites from agriculture runoff

  • Arsenic, a naturally occurring element in Montana bedrock

  • Coliform bacteria, which may indicate contamination from septic systems or animals

  • Iron, manganese, or sulfur, which can stain appliances or smell unpleasant


đź§Ş What Should Buyers Test For?

Montana DEQ and local health departments recommend testing for:

Test Why It Matters
Total coliform bacteria Indicates bacterial contamination (septic/sewage)
Nitrates/nitrites Dangerous for infants, can cause “blue baby” syndrome
Arsenic Long-term exposure can cause health problems
Lead & copper Often from old plumbing
pH, hardness, iron, manganese Affects taste, staining, appliance wear

đź’ˇ Tip: Use a certified lab, like the Montana State Public Health Lab or local services in Bozeman and Livingston.


🔧 What If There’s a Problem? Fixes & Negotiation Tips

If contamination is found, here are some possible fixes:

Problem Common Solutions
Coliform bacteria Shock chlorination, UV treatment systems
Nitrates Reverse osmosis, ion exchange, or new well placement
Arsenic Adsorptive media filtration, reverse osmosis
Hard water/iron Water softeners or iron filters

Who Pays—Buyer or Seller?

That depends on:

  • Inspection Contingencies in the purchase agreement

  • State/local disclosures (Montana doesn’t mandate well testing, but banks might)

  • Negotiation Power—in today’s more balanced market, buyers can at certain times request that sellers handle water system fixes before closing

🔥 Pro Tip for Sellers: Pre-listing water tests can be a smart move! It builds trust with buyers and speeds up negotiations.
