If you own a home in Stagecoach or Oak Creek, your well is one of your most important systems. You want clean, reliable water year-round, and you also want clarity on testing, treatment, and what to expect in a mountain setting. In this guide, you’ll learn what to test, how often to test, common issues in South Routt wells, treatment options that actually work, and key steps for real estate transactions. Let’s dive in.
South Routt well water at a glance
Private wells serve many properties in Stagecoach, Oak Creek, and nearby areas. Most tap fractured rock or alluvial aquifers influenced by mountains, runoff, and nearby surface water. That mix can create seasonal bacteria risks and elevated minerals.
Common contaminants
- Bacteria: Total coliform and E. coli are the primary acute health concerns, especially after heavy rain, spring melt, or any disturbance at the wellhead.
- Nitrate: Often tied to septic systems or past agricultural inputs. It is critical for infants and pregnant people. The federal benchmark used as guidance is 10 mg/L as nitrogen.
- Naturally occurring elements: Arsenic and uranium can appear in Colorado mountain groundwater. Public water system benchmarks often used as guidance are arsenic at 10 µg/L and uranium at 30 µg/L.
- Iron and manganese: Common in mountain aquifers. They stain fixtures, affect taste and odor, and can foul plumbing.
- Hardness: Elevated calcium and magnesium are routine. Hardness affects appliances, hot water systems, and soap use.
- Other considerations: Hydrogen sulfide odor, VOCs from fuel sources if present, and radon in water in uranium-bearing geology.
Why it varies seasonally
Snowmelt and summer storms can move surface water into shallow groundwater. That can spike turbidity and bacteria, especially if the wellhead is not sealed or if surface drainage pools around the casing. Pay extra attention to testing after runoff and any flooding.
What to test and when
Testing gives you a clear baseline and helps you spot changes early. Use a CDPHE-certified laboratory for reliable results and follow the lab’s instructions exactly.
Baseline testing at purchase or first occupancy
Start with a comprehensive panel to understand your water chemistry and any health risks:
- Bacteriological: Total coliform and E. coli (same sample)
- Nitrate and nitrite
- General chemistry: pH, total dissolved solids (TDS), conductivity, hardness, sodium, sulfate, chloride
- Iron and manganese
- Arsenic and uranium
- Lead if plumbing is older
- VOC screen if there is on-site fuel storage or spill risk
- Radon in water if your geology suggests risk or if air radon tests are elevated
Ongoing owner cadence
- Annually: Bacteria (total coliform and E. coli) and nitrate
- Every 1–3 years: General chemistry, hardness, iron, manganese, TDS
- Every 2–5 years: Arsenic and uranium, sooner if initially detected or if treatment is installed
- Immediately: After flooding, well work, plumbing work, or if anyone becomes ill
- After shock chlorination or treatment changes: Retest for bacteria until clear
Test triggers to watch
- Sudden taste, odor, or staining changes
- Drop in pressure or flow
- Nearby fuel tank issues or spills
- Construction or ground disturbance near the well or septic system
How to collect a good sample
Accurate sampling is half the battle. Follow your lab’s instructions precisely.
- Use the lab’s sterile bottles and do not touch inside the cap.
- Sample from a cold water tap per lab guidance. Some labs want a short flush; others want a direct first-draw.
- Keep bacteriological samples cool and deliver within the required time window, often within 24 hours.
- Label everything neatly and complete the chain-of-custody form if provided.
Make sense of results
Bacteria
- Any E. coli detection is a health hazard. Do not drink or cook with the water, use bottled water, contact public health, shock chlorinate, and retest.
- Total coliform positive but E. coli negative suggests a pathway for contamination. Inspect the wellhead, consider chlorination, and retest.
Nitrate
- If nitrate is above 10 mg/L as nitrogen, do not give well water to infants under 6 months, and pregnant household members should consult a health provider. Plan for appropriate treatment or an alternate source for drinking water.
Arsenic and uranium
- If above guidance levels (arsenic 10 µg/L, uranium 30 µg/L), arrange certified treatment for drinking water or use an alternate source until resolved. Point-of-use reverse osmosis for drinking water is a common and effective approach.
Minerals and aesthetics
- Iron and manganese cause staining, off-tastes, and can gum up fixtures. They are usually aesthetic and operational issues rather than acute health risks.
- Hardness scales appliances and heaters and increases soap use. Softening can improve comfort and protect plumbing.
Treatment that fits your water
Match the treatment to the contaminant. A softener will not fix bacteria or arsenic, and a UV unit will not remove hardness.
Whole house vs drinking water
- Point-of-entry (POE) treats the whole home. Examples: softeners, iron filters.
- Point-of-use (POU) treats a single tap, usually kitchen drinking water. Examples: under-sink reverse osmosis.
Bacteria control
- Shock chlorination: Useful after contamination or well work. Follow guidance and retest until clear.
- Ultraviolet (UV) disinfection: Highly effective for bacteria when water is clear. Requires prefiltration and an annual lamp change.
- Continuous chlorination: Provides residual disinfection but needs proper dosing, contact time, and safe handling.
Iron and manganese
- Oxidation and filtration: Air injection, catalytic media, or manganese greensand with backwashing can be very effective.
- Softeners: Can help with low levels of dissolved iron but may foul at higher levels.
Hardness
- Ion-exchange softeners: The standard solution for calcium and magnesium. Expect routine salt replenishment and periodic resin maintenance.
Nitrate
- Reverse osmosis at the kitchen tap is a practical choice for drinking water.
- Whole-house ion exchange for nitrate is possible but more complex, with brine and waste considerations.
Arsenic and uranium
- POU reverse osmosis is effective for drinking water.
- Whole-house options include adsorption media or ion exchange. Use qualified installers and follow disposal rules for spent media.
Radon and VOCs
- Radon in water can be treated with aeration systems that vent off-gas safely. Granular activated carbon can work but concentrates radioactivity in the filter, which then requires proper handling.
- VOCs and petroleum compounds often respond to granular activated carbon or air stripping, depending on the exact compounds.
Simple maintenance checklist
Use this quick cadence to protect your well and treatment systems.
- Monthly
- Inspect visible equipment for leaks and confirm freeze protection.
- Check salt levels if you have a softener.
- Every 3–6 months
- Replace sediment or prefilters as recommended by the manufacturer.
- Annually
- Test for total coliform and E. coli.
- Inspect the wellhead. The cap should be secure and drainage should slope away.
- Service UV and other treatment units per manufacturer guidance.
- Every 1–3 years
- Test general chemistry, hardness, iron, manganese, and TDS.
- Every 2–5 years
- Retest arsenic and uranium. Test sooner if previously detected or after treatment changes.
- Every 5–10 years
- Review pump performance and service if flow or pressure declines.
- Replace aging treatment media per manufacturer guidance.
Protect your well and records
- Records: Well logs and drilling records are typically filed with the Colorado Division of Water Resources and may also be in county records. These show depth, casing, static level, and formations.
- Setbacks: Maintain recommended distances from septic systems, fuel tanks, and animal yards. Local health departments can confirm the required setbacks.
- Wellhead: Ensure the casing is properly grouted and the cap is tight and vermin-proof. Grade the surface so water flows away from the well.
Buying or selling with a private well
If you are preparing to list or considering a purchase, plan your water due diligence early.
- Sellers
- Pull your well log, gather maintenance and treatment records, and order a recent test. Address clear issues or disclose them.
- Buyers
- Include a private well inspection contingency. At minimum, test total coliform and E. coli, nitrate, pH, TDS, iron, manganese, arsenic, and lead. Add uranium, VOCs, and radon if location or site history suggests risk.
- Allow enough time for lab turnaround, especially if you need expedited analysis.
- Immediate actions for common results
- Positive E. coli: Stop consuming the water, contact public health and a well contractor, shock chlorinate, and retest.
- Elevated nitrate: Do not give water to infants under 6 months and consult health providers for pregnant household members. Install appropriate treatment for drinking water.
- Arsenic or uranium above guidance: Use certified treatment or an alternate drinking water source until corrected.
- Iron, hardness, or odor: Treat to protect fixtures and comfort. These are typically aesthetic, not acute health risks.
