The Huntingburg Municipal Water system in Dubois County provides surface water to around 6,526 people with 2,692 connections. According to EPA UCMR3 testing from 2013 to 2015, 1,4-dioxane, a cyclic ether solvent stabiliser, was monitored in this public water supply. Twelve samples tested below the federal reporting level of 0.07 micrograms per liter (µg/L), equivalent to 0.07 parts per billion (ppb), with no detections above this threshold. This data does not reflect individual household water quality but offers a snapshot of the public system.
1. Why a Low-Level Detection Is Reported to Three Decimal Places and What Precision Means Here
Reporting level defines the smallest measurable concentration reliably captured by EPA methods.
Values below 0.07 µg/L are considered nondetect for regulatory and informational purposes.
Three decimal place precision ensures clarity in low-level detections, aiding risk evaluation.
Reported nondetect results do not imply absence, only that concentration was below quantifiable limits.
2. Why 1,4-Dioxane Moves Ahead of the Solvent Plume It Stabilized, and What That Means Downgradient
Being highly soluble and miscible, 1,4-dioxane travels faster than many co-contaminants.
Its mobility can cause presence in groundwater away from original industrial sources.
This movement pattern informs monitoring locations for affected water sources.
Understanding transport behavior is important for anticipating future detections.
3. Why Carbon and Boiling Do Little for This Ether, and Which Technologies Are Actually Documented
Activated carbon filters typically have limited adsorption capacity for 1,4-dioxane molecules.
Boiling water is ineffective due to 1,4-dioxane's boiling point and miscibility with water.
Specialized technologies designed for this contaminant have been tested and documented.
The C-Series 1,4-Dioxane Filter uses targeted methods to treat this cyclic ether effectively.
4. Which Fixtures, Appliances or Processes Are Affected First and Why
Any water outlet can introduce 1,4-dioxane since it dissolves completely in water.
Household drinking and cooking taps are primary points of contact.
Water-using appliances that heat or vaporize water may concentrate exposure.
Awareness of which water uses matter most can guide treatment priorities.
5. How to Judge Treatment Capacity Against the Household's or Facility's Daily Demand
Estimate average daily water consumption to select equipment sized for continual use.
Verify the filter's documented capacity to maintain performance over expected demand.
Consider peak usage times to avoid diminished effectiveness.
Matching capacity to household needs ensures efficient use of the documented technology.
6. A Worked Example: Reading the Record's Median and Range as a Homeowner Would
The Huntingburg system showed no measured concentrations above 0.07 µg/L between 2013 and 2015.
The EPA’s reference concentration for cancer risk is 0.35 µg/L, higher than any reported readings.
This suggests the local public water has had 1,4-dioxane levels below typical concern thresholds during monitoring.
Still, individual homes may want to test their own water if specific exposure concerns arise.
The above reflects the Huntingburg Municipal Water system's testing scope, capturing system-wide surface water quality. For precise knowledge of your household's 1,4-dioxane content, individual water sampling and analysis are required. This information is available from the U.S. Environmental Protection Agency's Safe Drinking Water Information System and the UCMR3 database, which document public water system occurrences nationwide.
The C-Series 1,4-Dioxane Filter ships ready to configure and is developed specifically to address low-level cyclic ether concentrations where treatment is desired. Consider your daily water usage and the documented performance of the device when selecting equipment to reduce household exposure.
