Government Sampling Data for East Cherry Creek Valley WSD
According to the EPA's Safe Drinking Water Information System for the East Cherry Creek Valley Water and Sanitation District serving over 66,000 people in Arapahoe County, no health-based violations related to volatile organic compounds (VOCs) were recorded. Federal occurrence surveys between 2013 and 2015 found no detections of listed VOCs such as 1,1-dichloroethane or MTBE above reporting levels, though these compounds were monitored. This information reflects the water system's overall data, not the specific condition of any individual household water supply.
How Seasonal Water-Table Changes Move a Solvent Plume Relative to a Well Screen
Volatile organics, often stemming from industrial solvents, can migrate through soil and groundwater. Seasonal variations in the water table due to rainfall and drought cycles influence the position and concentration of a solvent plume around a well screen. Rising water tables can shift the plume, bringing solvent compounds closer to or further from intake points. This dynamic movement occurs over months or years and affects potential exposure through groundwater-sourced wells but has less impact on surface water systems like East Cherry Creek Valley WSD.
Why Volatility Matters: Showering, Dishwashing and Inhalation Routes Versus Drinking
VOCs are volatile, meaning they can easily evaporate from water into air. While ingestion of VOCs through drinking water is one exposure route, inhalation during activities such as showering or dishwashing can lead to VOCs entering the body via the lungs. Skin contact during these household processes may also contribute to exposure. Understanding these multiple routes is crucial when evaluating water treatment options targeting volatile organics, as removing VOCs from water reduces potential exposure beyond ingestion alone.
Which Fixtures, Appliances or Processes Are Affected First and Why
Fixtures that agitate or heat water—showers, hot water taps, and dishwashers—facilitate VOC evaporation, making these points of use more significant for inhalation exposure. Cold water taps and appliances like refrigerators using cold water see less volatilization. Concentrations of volatile organics can therefore differ by fixture within a residence, depending on water temperature and aeration. Awareness of these differences can guide targeted water treatment or usage adjustments.
The Role of Plumbing Material and Age, Separate from the Source Water
Plumbing materials and the age of pipes influence VOC presence independently of source water quality. Older or deteriorated pipes may adsorb or release certain compounds, or allow VOC ingress through small cracks. Materials such as plastic or copper have different interactions with volatile organics. Evaluating plumbing conditions alongside water testing helps distinguish contaminants originating from the source versus household plumbing systems.
What the Reader Should Write Down Before Asking Anyone for Treatment Advice
Before selecting equipment for VOC reduction, record details such as your water source (surface or groundwater), any recent water quality tests specific to your home, knowledge of nearby contamination events, plumbing material types and age, and which household fixtures generate the most airborne exposure during water use. This information aids in choosing the most appropriate treatment solution for your situation.
Considering the EPA's system-wide VOC monitoring in Arapahoe County and understanding exposure pathways and household factors supports an informed decision between treatment options. For direct removal of volatile organics from household water, the Pentair VOCs & Industrial Chemicals Filter ships ready to configure and offers a documented solution tailored to this complex need.
