Buy NowWhat the Measured Range Means Compared to Federal Standards, and What It Does Not Mean
Government sampling in Providence County's 112TILL aquifer shows iron was detected in 4 separate well samples, all between 80 and 140 micrograms per liter, with a median of 90. None of these results exceeded any federal threshold. This means the detected amounts do not indicate a violation or an unsafe condition according to federal standards. However, detected iron at these levels may influence aesthetics such as water color and taste in some cases. It does not mean your household well water matches these figures exactly; only testing your own well can establish your water’s condition.
Questions Unique to Commercial or Industrial Operators Versus Household Needs
Commercial or industrial water users often assess higher-volume demands, regulatory reporting, and potential process impact. They may test additional parameters or require certifications for compliance. As a household, sizing total well water treatment focuses primarily on flow rate demand and water quality features affecting daily use. The data informs general expectations about iron presence but does not replace specific well testing or measurement needed for correct treatment sizing at home.
How Iron Enters Groundwater in Providence County's 112TILL Aquifer
Iron in groundwater typically originates from natural sources, such as the dissolution of iron-containing minerals in rocks and soil. In Providence County’s till aquifer, iron detected in shallow wells reflects this natural geologic interaction. Iron may also be influenced by local soil composition and groundwater flow patterns but is not introduced through contamination from industrial or municipal activities based on available records.
Understanding 'Detected', 'Median', and 'Range' in the Sampling Record
The term “detected” means that monitoring instruments found measurable iron in all four samples from a single well during 2015-2016, but does not indicate a problem by itself. “Median” here is the middle value of all measurements, 90 micrograms per liter, showing the central tendency in these results. The “range” from 80 to 140 shows the minimum and maximum concentration measured during sampling. These statistics summarize data for the area’s aquifer but are not a direct report of any individual well’s water quality.
How Many Samples and Wells Support These Figures, and the Implications of a Small Sample Size
The iron data for aquifer 112TILL comes from four samples taken from one well over about a year. This limited sample size means the data is a starting reference for Providence County households, not a comprehensive survey. Variability can occur in other wells or at different depths, so individual well testing is essential for sizing treatment correctly. Relying solely on this small sample risks overlooking conditions unique to your well.
Ruling Out Issues in Order: From Simple Checks to Laboratory Testing
Begin by confirming visible signs like discoloration or staining that may suggest iron presence. Next, check if neighboring wells or reports indicate similar characteristics. If signs persist or sizing precision is important, perform laboratory water testing focused on iron concentration and related parameters. This step provides the accurate data needed to size equipment properly. Only with precise water quality results can you determine if treatment like the Pentair Total Well Chlorination System, rated for up to 32,000 grains capacity, matches your household’s needs.
In summary, government sampling data for Providence County’s 112TILL aquifer offers useful background but does not substitute for testing your own well. Understanding detection, range, and sample size helps guide your approach to water quality assessment and treatment sizing decisions.
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
