Private Well Testing in Manhattan: Free Local Resources

If your home in Manhattan runs on a private well, you probably have one big question: is my water safe to drink today? You care about your family’s health and you want clear, local guidance without the runaround. In this guide, you will learn what to test, when to test, and how to tap into free or low-cost programs right here in Gallatin County. You will also get simple sampling steps and tips on what to do if a result comes back high. Let’s dive in.

Why test your Manhattan private well

Private wells are not regulated like public water systems. You are responsible for testing and maintaining your water quality. Health agencies recommend that you test at least once a year for total coliform bacteria and nitrate. You should also test after flooding, heavy rains, septic issues, well repairs, or any time water taste, color, or odor changes.

If your household includes infants, pregnant people, or anyone with a weakened immune system, plan to test more often. You may also consider a broader chemical screen once to establish a baseline. That baseline helps you track changes over time.

Free and low-cost resources in Gallatin County

Two local programs work together to support private well owners in our area. The Gallatin Local Water Quality District (GLWQD) and the Gallatin County Conservation District (GCCD) coordinate kit distribution, education, and cost-share assistance. These are countywide programs that include Manhattan and nearby communities.

What these programs typically cover

• Sterile bottles and kits for bacteria and nitrate testing.
• Pick-up and drop-off options in Manhattan and Bozeman, plus seasonal events.
• Clear collection instructions and transport to certified labs.
• Cost-share that can reduce or cover lab fees for eligible residents. Availability varies by year and funding.

Where to pick up and drop off kits

Programs often use the Manhattan town office or community events for kit pick-up and drop-off. In Bozeman, look for GLWQD or GCCD offices or other county facilities. Locations and hours change with the season and grant cycles, so call or email before you go. If a local pickup is not convenient, ask about mail-out kits or walk-in options in Bozeman.

Quick steps to confirm today’s options:

• Check the current GLWQD and GCCD program announcements for dates and sites.
• Call to verify addresses and hours for Manhattan and Bozeman drop-off.
• Ask whether kits are free right now, or if a small fee applies at drop-off.

What to test and when

Plan for a simple, repeatable testing schedule. Start with the essentials, then add tests based on your home’s plumbing, local geology, or known nearby risks.

• Annual minimum: total coliform bacteria, E. coli, and nitrate.
• One-time or periodic baseline: arsenic and uranium, especially in parts of southwest Montana where these may occur naturally.
• Plumbing related: lead if your home has older pipes or solder, and pH, hardness, iron, and manganese for aesthetic or plumbing considerations.
• Situational: chloride or sulfate if you suspect septic or surface influence, and volatile organic compounds if you live near industrial or petroleum activity.

Quick testing calendar for Manhattan

• Spring, April to May: test for bacteria and nitrate. This timing follows thaw and high water, and it comes before heavy irrigation runoff.
• After events: test any time after flooding, heavy rain, septic issues, new pump or plumbing work, illness in the household, or if a well has been idle.
• Vulnerable households: test bacteria and nitrate more frequently, and consider a broader chemical screen.

Key thresholds to know

• Nitrate: the Maximum Contaminant Level is 10 mg/L as nitrogen (NO3-N). Results above this level require action for infants and pregnant people.
• Bacteria: any E. coli detected signals fecal contamination and an acute health risk. The presence of total coliforms suggests a pathway for contamination and calls for follow-up.

How the cost-share works

Local districts secure grant and program funds to reduce the cost of testing. In many seasons, basic bacteria and nitrate tests are free or low-cost for Gallatin County residents. Expanded panels, such as metals or VOCs, may carry added fees unless the program covers them that year. Funding is cyclical, and quantities can be limited.

Before you pick up a kit, call to confirm what is covered today, whether eligibility applies, and how to handle payment if any fee is required. Ask about expected turnaround times and how you will receive your results.

How to collect and submit a valid sample

Follow the lab’s instructions that come with your kit. Accurate results depend on proper collection and timely delivery.

Step-by-step best practices:

1. Use the sterile bottle provided. Do not touch the inside of the cap or bottle rim.
2. For bacteria, collect a first-draw cold water sample after water has been still for 6 to 12 hours, unless the kit directs a different method.
3. For nitrate and other chemicals, follow the kit directions. Some labs want a first-draw sample, others ask you to run the tap briefly.
4. Label the sample with the ID, date, and time. Note the well and pump status if requested.
5. Keep samples cold, either on ice or in the refrigerator, and deliver them within the specified holding time. Bacteria samples often need to arrive within 24 hours.
6. Avoid chlorinating the system 24 to 48 hours before a bacteria sample. If you recently disinfected, tell the lab.

If your results show a problem

• Bacteria present: do not drink the water until you resolve the issue. Use bottled water for drinking and cooking. You may need to disinfect the well, inspect the system for damage, and retest.
• Nitrate above the MCL: protect infants and pregnant people right away. Consider treatment options such as reverse osmosis or ion exchange, or use an alternate water source while you plan next steps.

Lab certification and your report

GLWQD and GCCD route samples to state-certified labs and share results with you. If total coliforms are present, plan a resample and a system check. If E. coli is detected, take immediate health precautions. For nitrate over 10 mg/L as nitrogen, address infant and pregnancy risks first, then explore treatment. For arsenic, uranium, or other metals, compare results to federal standards and seek local guidance on follow-up and treatment.

If you are unsure how to interpret a result, contact the local program for help. Staff can explain what the numbers mean and suggest practical next steps.

Local contacts and next steps

• GLWQD: ask about current testing events, kit availability, pickup and drop-off details, and help interpreting results.
• GCCD: confirm cost-share status, eligibility, and any fees this season.
• County extension or health offices: request general guidance and referrals.
• Certified labs: follow their directions for collection, holding times, and delivery.

Before you head out, verify addresses and hours for Manhattan and Bozeman drop-off locations. Ask if mail-out options are available if pickup times do not fit your schedule.
