Water Quality Record in Muscatine County Aquifer 111ALVM
Government sampling by the U.S. Geological Survey for groundwater in Muscatine County's aquifer 111ALVM shows iron was detected in most wells sampled. The median iron measurement was 282.5 micrograms per liter (ug/L), ranging from 86.1 to 1540 ug/L across four wells sampled between 2011 and 2017.
Comparing Muscatine County to Neighboring Areas
Variation in Iron Levels
Nearby counties may report different median and range values, but such differences reflect area-wide conditions and not individual wells. Comparing these published figures helps understand regional iron presence but cannot predict your home's water quality.
Limits of Regional Data
Neither higher nor lower regional iron levels directly indicate a water treatment need for your household, as source water concentration can vary significantly.
The Influence of Plumbing Materials and Age
Iron from Source vs. Plumbing
Iron found in water is partly from the aquifer and partly influenced by pipes and plumbing system age. Older or corroded pipes can add rust to water even when source concentrations are low.
Recognizing Plumbing-Related Rust
Visible rust stains or discoloration could stem from plumbing materials rather than just groundwater iron.
Sampling Depth and Number of Wells
Sample Size and Range
The iron data is based on five results from four wells, sampled at depths from 14 to 193 feet. This relatively small sample size means conclusions are area-level indications rather than conclusive for each property.
Interpreting Limited Samples
Small samples provide clues about typical iron presence but require homeowners to test their own water for precise treatment needs.
Reading Median, Range, and Detection Terms
What 'Median' Means
The median 282.5 ug/L indicates half the sampled values were above and half below this iron level, representing a typical concentration in the area.
Understanding 'Range'
The range from 86.1 to 1540 ug/L shows variability in iron levels among wells, reflecting different geological or well construction conditions.
Meaning of 'Detected'
Iron was detected in four of five samples, meaning instruments measured it but this is not a violation or safety concern.
Applying This Information as a Homeowner
Knowing this regional data can guide expectations about potential iron issues but testing your own water is essential. Testing will establish if iron concentrations may cause rust stains or require treatment.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2017-06-19. 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.
