In Arapahoe County, CO, residents may notice concerns about volatile organic compounds (VOCs) when evaluating water quality at the tap. These solvent compounds are part of a larger class of contaminants that can vaporize easily and may enter the body through water use beyond drinking alone. Understanding the nature of VOCs and what the government’s monitoring data shows for the local public water system is key to making informed choices regarding household water treatment options.
Why Volatility Matters: Showering, Dishwashing and Inhalation Routes Versus Drinking
Volatile organic compounds such as 1,1-dichloroethane, chloromethane, and MTBE are known to evaporate from water into air. This property means exposure can occur not only by drinking the water but also during activities like showering, bathing, and dishwashing. When water containing volatile solvent compounds releases vapors indoors, inhalation and skin contact become additional routes of exposure. This makes controlling VOCs in household water a more complex task than for contaminants that stay dissolved and non-volatile.
Why Aesthetic Secondary Standards Differ from Health-Based Limits, Applied to This Constituent
Government monitoring of the East Cherry Creek Valley Water and Sanitation District, serving 66,130 people in Arapahoe County, shows no VOC detections above reporting levels in federal surveys from 2013-2015. Importantly, this water system has zero health-based violations on record. Aesthetic secondary standards for compounds that can affect taste or odor are distinct from health-based limits. Exceeding a secondary standard does not mean the water is unsafe, only that it might have qualities some find unpleasant or that could cause staining or corrosion.
What the Reader Should Write Down Before Asking Anyone for Treatment Advice
- The name of your water system: East Cherry Creek Valley WSD (CO0103035)
- Whether your water is surface-supplied or from a well (this system uses surface water)
- Any documented test results you have from certified water testing labs, specifically for VOCs or volatile organics
- Any specific volatile organics detected or reported, including their concentrations in micrograms per liter (µg/L) or parts per billion (ppb)
- Your household uses of water that might increase exposure, like frequent hot showers or steam-intensive cooking
What Happens When This Problem Is Left Untreated for Years, Stated Without Exaggeration
If VOCs are present in household water—even at low levels as might be found in some areas—they can contribute to unpleasant tastes or odors and ongoing low-level exposure via inhalation or skin contact. Although the East Cherry Creek Valley water system has shown no detections above reporting levels, individual wells or plumbing conditions may vary. Long-term exposure to some volatile solvent compounds is a concern that justifies monitoring and, if needed, treatment to reduce possible health risks and improve water quality.
What Distinguishes This Problem from the Two Problems Most Often Confused with It
VOCs differ clearly from two commonly confused water quality issues: microbial contamination and inorganic mineral hardness. Unlike microbes, VOCs are chemical compounds that require different testing methods and are not removed by disinfection. Unlike hardness caused by calcium or magnesium, VOCs are volatile solvents needing specialized treatment technology. Understanding these distinctions helps target solutions accurately rather than using generic approaches that will miss solvent compound concerns.
For households in Arapahoe County weighing treatment options for volatile organic compounds, the recommended course is to have a certified laboratory test your specific water supply for VOC presence and concentrations. This testing should include the common VOCs monitored in your public water system’s area, such as 1,1-dichloroethane, chloromethane, and MTBE, reported in micrograms per liter (ppb).
Once you have this data, the Pentair VOCs & Industrial Chemicals Filter system ships ready to configure and is documented for reducing a broad range of solvent compounds effectively. Its design addresses the volatility and chemical nature of VOCs, providing a specialized filtration option suited to household needs in Arapahoe County.
