Seasonal and Multi-Year Variation in Sherburne County Water Quality Records

Sampling spans seven years, showing changes over time

The U.S. Geological Survey collected groundwater samples from 16 wells between 2011 and 2018, capturing changes that reflect seasonal and year-to-year variability in Sherburne County's aquifer 112PLSC.

Measured iron levels range widely over the period

Reported iron concentrations ranged from 4.2 to 15,400 micrograms per liter, with a median of 1,086 micrograms per liter, indicating fluctuating iron presence in the groundwater across the sampled wells and timeframe.

Plumbing Materials and Their Influence Separate From Source Water

Older pipes can show rust unrelated to groundwater iron content

Rust-colored water is not solely caused by groundwater iron; plumbing material and age within a home can contribute rust particles, affecting water appearance independently of the original water source.

Metal plumbing may react with water characteristics in various ways

Hardness and iron in the source water can interact with metal pipes, leading to staining or deposits. This interaction differs from the raw water iron content and is important to consider in assessing treatment needs.

Information to Record Before Seeking Treatment Guidance

Document any lab tests of your own well water

While area data provides context, an individual well test is necessary to know your specific water quality. Note the concentrations, sampling date, and depth for accurate advice.

Note water color, taste, and staining patterns

Observations such as reddish tint, metallic taste, or stains on fixtures can help distinguish between hardness and rust effects when combined with water tests.

Record household water use patterns and seasonal variations

Changes in water appearance or hardness related to heavy use periods or seasons provide clues about fluctuations in source water or plumbing impacts.

Household Signs That May or May Not Indicate Well Rust and Hardness

Reddish or brown water suggests presence of iron compounds

This is a common sign of rust from iron but can also arise from pipe corrosion, so it alone does not confirm groundwater iron levels.

White or cloudy deposits typically indicate hardness minerals

Hard water often leaves scale on fixtures and in kettles but is distinct from rust stains and generally doesn’t affect water color.

Musty odors or taste changes are not reliable indicators of rust or hardness

These symptoms can arise from various causes unrelated to iron or hardness and should prompt broader water testing.

Interpreting Detected, Median, and Range in Area Sampling

Detected means the instrument measured iron above reporting limits

In some wells, iron was detected while in others it was below the reporting limit during the 2011–2018 sampling period.

The median provides the middle value of detected iron results from wells sampled

A median iron level of 1,086 micrograms per liter summarizes typical presence in the aquifer but does not specify individual well conditions.

The wide range highlights variability across wells and time

From as low as 4.2 to as high as 15,400 micrograms per liter, this range shows local fluctuations but does not mean every well will experience high iron.

Effects of Sample and Well Depth on Water Quality Expectations

Sampled wells were between 8 and 57 feet deep in the aquifer

Different well depths access varying groundwater layers which can differ in iron and hardness content; shallower wells may have different water characteristics than deeper ones.

Depth and aquifer characteristics influence mineral content

Hardness and rust issues are tied to regional geology; the aquifer’s composition at each depth affects what is likely to be present in household water.

These facts describe groundwater iron levels documented by USGS in Sherburne County’s aquifer 112PLSC from samples taken between 2011 and 2018 and should guide what you test and observe before choosing a treatment approach. For full details, consult the USGS groundwater data source.
