Providence County, Rhode Island, lies above aquifer 112TILL, where groundwater sampling by the U.S. Geological Survey found iron concentrations ranging from 80 to 140 micrograms per liter (ug/L) in sampled wells. These wells were shallow, approximately 18 feet deep. Importantly, none of these measurements exceeded federal thresholds for iron, which means the detected levels are within federally accepted ranges and do not indicate a health violation.
It's essential to understand that these figures describe typical conditions in wells within this area but do not define the water quality of any individual well. Actual water quality can only be determined by direct testing of your own well water.
Interpreting Median and Range for Your Household Context
With a median iron concentration of 90 ug/L reported in the area, you can consider this value as a benchmark for typical groundwater iron presence in Providence County. The range of 80 to 140 ug/L shows some variability, which is common in groundwater due to natural aquifer composition and seasonal fluctuations. Homeowners should consider this range when evaluating their own well results and sizing treatment equipment to ensure capacity and performance accommodate possible concentration variations.
Sources of Iron in this Aquifer Region
Iron in groundwater often originates from natural geological formations. In Providence County’s 112TILL aquifer, iron is mostly released from iron-bearing minerals in soils and rocks, dissolving slowly into the water under certain chemical conditions. This natural process leads to measurable iron in groundwater and thus well water. Groundwater age, aquifer materials, and redox conditions influence how much iron is dissolved and present in well samples.
Consequences of Leaving Iron Untreated in Well Water
If iron concentrations in well water persist without treatment over time, households may notice aesthetic issues such as reddish-brown staining on plumbing fixtures, laundry, and dishes. High iron levels can also cause metallic taste in drinking water and may promote the growth of iron bacteria, which can cause slime deposits and unpleasant odors. These effects do not affect water safety but can interfere with daily household water use and maintenance.
Stepwise Approach to Diagnosing Well Water Iron Levels
Before sizing or selecting a treatment system, begin by checking visible signs like staining or taste changes. Next, conduct an independent water test from a certified laboratory to measure iron concentration and confirm presence. Testing ensures accurate data specific to your well, as regional data alone cannot predict your water's iron levels. Understanding your own water sample data is essential to appropriately match treatment capacity to your household needs.
How the Autotrol Complete Well System Addresses Iron in Water
The Autotrol Complete Well System is designed to handle comprehensive water treatment for residential wells, including reducing iron concentrations commonly found in the Providence County aquifer. With a grain capacity of 32,000, it effectively removes iron particles and neutralizes them through filtration and oxidation processes. This system ships ready to configure, allowing homeowners to tailor treatment to their water characteristics and usage demands.
Relying on site-specific water testing, homeowners can select this system with confidence that it meets the performance demands indicated by their individual water quality results, rather than solely regional data.
What Providence County Area Data Does Not Determine
While U.S. Geological Survey iron data illustrates typical conditions in Providence County’s 112TILL aquifer, it does not provide a precise assessment for any individual residential well. The area’s data should not be interpreted as a direct description of your own well’s water. Only a laboratory test from your well sample can establish your water quality and inform the correct treatment sizing. This distinction is crucial to avoid misapplication of regional data and to make informed decisions about water treatment solutions.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2016-05-17. 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 (Providence County): 4 results from 1 wells, median 90.0 ug/L, range 80.0-140.0 ug/L; none above any federal threshold
