How many samples and wells stand behind the figures, and what does a small sample mean?

Between June 2010 and June 2012, the U.S. Geological Survey collected groundwater samples from three wells in Clackamas County’s aquifer 110ALVM. These wells, ranging from 57 to 71 feet deep, were tested 18 times in total, providing a modest but valuable picture of water pH in the area. While this sample size offers some insight into general water quality, it should not be taken as definitive evidence of every household’s water condition. Water chemistry can vary by well location, depth, and local geology, so individual testing remains essential to determine the exact corrosivity in your home’s water.

How does the Pentair Corrosive Water Damaging Pipes Filter address corrosive water?

The Pentair Corrosive Water Damaging Pipes Filter is engineered to reduce the harmful effects of corrosive water on your plumbing system. Corrosive water, often associated with lower pH levels, can accelerate pipe degradation and staining. This Pentair system works by adjusting water chemistry to reduce acidity and neutralize corrosive tendencies, helping to protect pipes and fixtures from damage. It ships ready to configure for residential settings, enabling you to address corrosive water without delay once you know your specific water chemistry.

What does seasonal or multi-year variation look like in the government sampling record?

Samples were collected over a two-year period from June 2010 to June 2012. During this time, pH values ranged from 6.6 to 7.7 standard units, sitting within the Environmental Protection Agency’s secondary standard range of 6.5 to 8.5 for aesthetic considerations. This indicates some natural variation in water chemistry over time, which can be expected due to changes in factors like rainfall, aquifer recharge, and localized water table shifts. However, none of the samples dipped below the lower pH boundary that would suggest increased corrosivity beyond typical regional expectations.

How should a homeowner interpret the median and range of pH values from the record?

The median pH of the sampled wells was 7.35 standard units, which is slightly above neutral (7.0) and well within the range considered non-corrosive by EPA secondary standards. The range from 6.6 to 7.7 shows that occasional mildly acidic water may occur but is not prevalent enough to indicate a consistently corrosive source. For a homeowner, this means that the aquifer feeding local wells generally produces water unlikely to be highly aggressive against pipes. Still, individual results may differ, so specific water testing is necessary to determine your home's water corrosivity.

How does pH enter groundwater or the distribution system in this region?

In Clackamas County’s aquifer 110ALVM, pH levels reflect the natural geological composition and the interactions between water and surrounding rock formations, soils, and organic material. Local factors such as mineral content, carbon dioxide levels in water, and biological activity influence the acidity or alkalinity of groundwater. Because this aquifer serves many wells, the recorded pH range captures these natural variations but does not imply contamination or unsafe conditions. Municipal systems, where applicable, generally treat water further to maintain quality within recommended ranges.

What should you not conclude from the area data?

It is important not to assume that the pH values reported for three wells in Clackamas County represent the exact pH of your home’s water. These figures do not detect nor rule out other water chemistry factors that can influence corrosion, such as dissolved oxygen, mineral content, or chlorides. Detection within the recorded range is not a violation or safety concern; it is a natural measurement of water quality. Only a certified laboratory test of your own water supply can provide specific results needed to decide on effective treatment. If corrosive water is confirmed, the Pentair Corrosive Water Damaging Pipes Filter offers a documented approach to help manage corrosivity and protect your household plumbing.

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 pH in the 110ALVM aquifer (Clackamas County): 18 results from 3 wells, median 7.35 standard units, range 6.6-7.7 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 18 sampled results fell below 6.5
