Local Water Source and Delivery

The water in Carlton County comes from aquifer 112TILL, a groundwater source reaching household taps through wells that may range in depth. This aquifer has been sampled regionally to understand its iron content and other characteristics. Water travels from the well through the household plumbing to fixtures and appliances, carrying any dissolved or particulate iron that might be present.

Household Symptoms Indicative of Iron and Rust Problems

Visible reddish or brown stains on sinks, tubs, or toilets

Such stains can be signs of iron oxidizing and settling on surfaces.

Iron-like metallic taste or discoloration in water

The presence of iron can cause water to have a metallic taste or a reddish tint after exposure to air.

Not all rusty-colored water indicates iron

Other minerals or sediment can cause discoloration, so symptoms alone are not conclusive.

Failure of previous treatment equipment

When existing equipment no longer reduces iron effectively, iron and rust symptoms can return or worsen.

Understanding Regional Sampling Data on Iron

Sampling timeframe and scope

Six wells in Carlton County's 112TILL aquifer were sampled over two days in May 2016 to measure iron levels.

Range and median iron concentrations

The tested wells showed iron levels ranging from 13.7 to 609.0 micrograms per liter, with a median value of 301.5 micrograms per liter.

Detections across all samples

Iron was detected in all sampled wells; none fell below the reporting limit.

No federal threshold was exceeded

None of the iron measurements in these samples surpassed any federal regulatory limits.

How Well Depth and Source Alter Expectations

Wells sampled ranged from 35 to 148 feet deep

Iron concentration can vary by depth due to geological layers and water chemistry.

Deeper wells may have different iron profiles than shallower ones

Water drawn from deeper aquifers may contain more or less iron depending on local conditions.

Surface water influence is minimal in groundwater aquifers like 112TILL

This reduces the likelihood of sudden changes in iron levels from surface contamination.

First Affected Fixtures and Appliances

Clothes washers and dishwashers

Iron deposits can cause staining on clothing and dishes.

Sinks, toilets, and bathtubs

These may show noticeable rust-colored stains where water is regularly present.

Water-using appliances with internal components

Iron buildup can shorten appliance lifespan or impair function over time.

The Role of Plumbing Materials and Age

Older iron or steel pipes may contribute additional rust particles

Corroding pipes can release rust into water beyond the source aquifer levels.

Plastic or copper plumbing typically does not add rust

These materials are less prone to rust formation and release.

Pipe condition affects iron presence separately from groundwater iron

Testing both source water and household plumbing is necessary to identify iron origins accurately.

Meeting Your Water Needs with Effective Treatment

For households in Carlton County experiencing iron and rust following equipment failure, testing your own water is essential to determine specific iron levels. In response, the Pentair Orange Iron & Rust Stains Filter ships ready to configure and is designed to address iron-related staining and taste issues. Selecting treatment aligned with your measured demand helps restore water quality for fixtures and appliances.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2016-05-13. 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 112TILL aquifer (Carlton County): 6 results from 6 wells, median 301.5 ug/L, range 13.7-609.0 ug/L; none above any federal threshold
