When you receive a laboratory test report listing arsenic in your water, the figures show measured concentrations in micrograms per liter (ug/L). For Clackamas County’s aquifer 110ALVM, US Geological Survey samples collected from three wells between 2010 and 2012 recorded arsenic levels ranging from 0.27 to 1.9 ug/L with a median of 0.805 ug/L. These wells were between 57 and 71 feet deep. None of these measurements exceeded federal arsenic thresholds, which means the recorded arsenic presence is below levels defined as regulatory limits.
Symptom Truths and Misconceptions About Arsenic and Household Water Quality
Households with arsenic in their water may notice no obvious taste, smell, or appearance changes, as arsenic is colorless and odorless. If your existing treatment system seems unable to keep up, it does not necessarily mean arsenic concentrations have spiked; other factors might include increased water usage or treatment capacity limits. Common household symptoms like staining or corrosion relate more to different water constituents. Arsenic presence is confirmed only by specific laboratory tests—visual or taste cues in water are unreliable indicators.
Plumbing Materials and Age Do Not Affect Arsenic Levels in Your Water Source
The arsenic levels documented for Clackamas County aquifer 110ALVM relate to the groundwater itself, not changes introduced by pipes or plumbing fixtures inside your home. While older plumbing can influence other water quality characteristics, arsenic originates in source water and is not generated or removed by plumbing materials or system age. Thus, plumbing condition does not cause variations in arsenic concentration found at the tap.
Additional Considerations for Commercial or Industrial Operators Using Groundwater from Aquifer 110ALVM
Unlike households, commercial or industrial users may ask about daily water volume demands, potential seasonal shifts, or multi-year trends in arsenic concentration impacting process water. For Clackamas County, the USGS data set is limited to six samples over two years, offering a snapshot rather than a continuous trend. Industrial operators typically require more frequent testing and capacity planning to address possible arsenic fluctuations not evident in this limited sample.
Comparing Arsenic Records Between Adjacent Counties Requires Careful Context
While nearby counties might report different median or range values for arsenic in groundwater, differences can stem from sample size, well depth, or geological variation. Clackamas County’s aquifer 110ALVM data represents a small set of wells sampled at moderate depth. Directly applying a neighboring county's arsenic levels to your situation risks overreading regional variability as a personal water quality indicator. Your water’s arsenic concentration can only be confirmed by a well-specific test.

The Pentair Arsenic Filter ships ready to configure and is designed to address arsenic removal needs based on the demand you have measured. Its maintenance involves periodic replacement of filter media or cartridges according to usage and water quality, ensuring consistent performance without the need for specialized tools or labor. Following the recommended maintenance schedule supports sustained arsenic reduction capacity, helping your household treatment keep pace with daily consumption.
For households in Clackamas County facing arsenic removal challenges, especially when existing equipment cannot keep up, the Pentair Arsenic Filter offers a documented solution. By matching your measured daily demand with this system's capabilities, you can enhance treatment effectiveness and manage arsenic according to your specific conditions.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2012-06-06. 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 Arsenic in the 110ALVM aquifer (Clackamas County): 6 results from 3 wells, median 0.805 ug/L, range 0.27-1.9 ug/L; none above any federal threshold
