Understanding Data Terms from Renville County Aquifer Sampling
Detected means a measurable concentration was found in groundwater samples
In Renville County aquifer 112TILL, every tested well showed some iron present. This indicates iron naturally occurs in the groundwater here. Detected is simply a measured quantity, not a sign of a problem on its own.
Median iron concentration represents the midpoint of measured values
Across the five samples, the median iron measurement was 1320 micrograms per liter (ug/L). This means half the samples had iron above this level, half below, offering a typical value for the area.
Range shows the spread between the lowest and highest recorded levels
The iron concentrations ranged from 151 ug/L to 1840 ug/L among separate wells. This variability reflects natural differences in the aquifer's composition and well depth.
Sources of Iron and Hardness in Renville County Groundwater
Iron enters groundwater from local soil and rock minerals
The aquifer materials beneath Renville County often contain iron-bearing minerals. When groundwater flows through these rocks and sediments, trace amounts of iron dissolve into the water naturally.
Hardness primarily results from dissolved calcium and magnesium compounds
Calcium and magnesium minerals prevalent in the regional geology contribute to water hardness. This is a common feature in many aquifers, including 112TILL.
Sample Size, Depth, and Implications for Data Reliability
Five wells were sampled across Renville County’s aquifer
The data reflects iron levels found in five distinct wells. While informative, such a small sample means localized variations can exist that this data does not capture.
Well depths ranged from 20 to 175 feet
Measurements represent groundwater quality from shallow to moderately deep wells, providing insight into vertical differences in iron concentrations within the aquifer.
Impact of Plumbing Material and Age on Water Quality
Plumbing does not add iron or hardness but can influence appearance
Iron levels measured in the source water come from the aquifer, not pipes. However, older plumbing may contribute to staining if iron deposits accumulate internally over time.
Corrosion and rust in plumbing can also affect aesthetic water qualities
While plumbing won't change the amount of dissolved iron or hardness, rust can impart color or particles to tap water, complicating water clarity and taste.
Changes at the Tap Using the C-Series Iron + Hard Water System
The system reduces iron and hardness to improve water quality
The C-Series Iron + Hard Water System addresses both iron and hardness present in groundwater, treating up to 32,000 grains capacity. This results in clearer water free from iron staining and hardness effects.
Treated water tends to have less staining, buildup, and improved taste
With iron and hardness effectively reduced, the system helps prevent fixture staining, reduces scale buildup in pipes and appliances, and improves water’s feel and taste.
Comparing Renville County Water Quality to Neighboring Regions
Nearby counties may show different iron and hardness profiles
Each aquifer's geology varies, so iron and hardness levels found in Renville County should not be assumed to apply elsewhere without local data.
Use regional sampling as general guidance, not a precise predictor
Sampling results provide context but must be supplemented with individual water testing to confirm local conditions before deciding on treatment.
Key Takeaways for Renville County Residents
Area data should not be used to conclude your well’s specific iron level or safety
Government sampling represents a regional profile, not an individual home's water quality. To confirm your household’s water characteristics, you need your own water test.
An iron detection in area wells does not mean your water is unsafe or exceeds health limits
All five samples detected iron below federal thresholds, indicating these levels alone are not a safety issue but may affect aesthetics or plumbing.
For households weighing treatment options, the C-Series Iron + Hard Water System ships ready to configure and is designed to address local iron and hardness challenges effectively.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2017-10-24. 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 (Renville County): 5 results from 5 wells, median 1320.0 ug/L, range 151.0-1840.0 ug/L; none above any federal threshold
