Information to Record Before Seeking Water Treatment Advice

Household Water Supply Source

Note whether your water comes from a private well or a shared system drawing from aquifer 211MNCS in Montrose County.

Age and Type of Existing Equipment

Document the brand and model of your current iron and rust treatment system and note when it ceased functioning properly.

Reported Water Quality Symptoms

Keep track of observable signs such as staining on fixtures, reddish tint in water, or metallic taste that prompted concern.

Recent Water Tests

If available, record any laboratory results for iron concentration from your own water source, as this will be essential for targeted treatment.

Influence of Sampling and Well Characteristics on Iron Expectations

Depth of Sampled Wells

Government samples from Montrose County’s aquifer 211MNCS were taken at depths between 8 and 42 feet, which can affect iron concentration ranges.

Type of Water Source

Groundwater drawn from this aquifer tends to show variable iron levels, influenced by geological conditions and well construction.

Variability Across Wells

Sampling data covers 15 distinct wells, indicating that iron can differ substantially even within the same aquifer region.

Distinguishing Aesthetic Standards from Health-Based Limits for Iron

Secondary Standards Guide Water Quality Appearance

Iron concentrations impact water color, taste, and staining potential, which are governed by aesthetic secondary standards rather than safety limits.

Health-Based Federal Thresholds

None of the 45 Montrose County aquifer samples exceeded federal health-based iron thresholds, indicating no recorded safety violations in the area-wide testing.

What Detection Means

A detection of iron simply confirms its presence above an instrument reporting limit, not a violation of any health standard.

Seasonal and Multi-Year Variation Reflected in Sampling Record

Sampling Timeline

Data was collected between July 2011 and March 2015, providing a multi-year snapshot of iron levels in the aquifer.

Range of Observed Concentrations

Iron levels in detected samples ranged from 4.8 to 25,400 micrograms per liter, demonstrating variability across years and locations.

Median Value Context

The median iron concentration was 98.05 micrograms per liter, representing a typical detected presence during the monitoring period.

Interpreting the Sampling Record Terms

Detected Versus Below Reporting Limit

Out of 45 results, 26 showed iron detected above the instrument reporting threshold, while 19 were below it, indicating non-detectable levels.

Median Explained

Median is the middle value of detected iron results, often a more representative indication than extremes.

Range Clarified

The wide range from 4.8 to 25,400 micrograms per liter shows that iron presence varies significantly among wells sampled in Montrose County.

What The Measured Iron Levels Mean

Comparison to Federal Health-Based Standards

No sample iron concentration exceeded any federal health-based limits, so the data does not indicate a regulated safety problem.

Implication for Household Water Quality

Iron concentrations above aesthetic standards may cause water discoloration or staining but do not necessarily indicate unsafe water.

Need for Individual Water Testing

Only testing your own household water can establish its precise iron content and help determine suitable treatment options.

When existing iron and rust equipment fails, households drawing from Montrose County’s aquifer 211MNCS may consider the Pentair Orange Iron & Rust Stains Filter, which ships ready to configure and addresses iron-related aesthetic issues based on your household's measured demand.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2015-03-13. These figures describe groundwater sampled in this area. They are not a test of any individual private well - only a test of that well can establish its own water.

On record: U.S. Geological Survey sampling of Iron in the 211MNCS aquifer (Montrose County): 45 results from 15 wells, median 98.05 ug/L, range 4.8-25400.0 ug/L; none above any federal threshold
