Water Source and Flow in Androscoggin County

The bedrock aquifer serving Androscoggin County is a deep groundwater source sampled between 262 and 304 feet below the surface. Water from this aquifer is drawn up through wells to provide household supply. Its characteristics reflect interactions with local geology over time, influencing water properties such as pH before reaching residential taps.

Interpreting Certified Laboratory Tests for pH

When testing water for acidity, certified laboratories report pH on a standard scale from 0 to 14, where lower values indicate acidity and higher values alkalinity. For household water, the U.S. Environmental Protection Agency's secondary standard for pH ranges from 6.5 to 8.5. This range is set for aesthetic considerations and impacts like taste and corrosion potential rather than direct health risks. A lab test shows the pH value at the time of sampling, which helps identify if water tends to be acidic (below 6.5), neutral, or alkaline. Knowing this aids in choosing appropriate water treatment.

Comparing Androscoggin County’s Aquifer Record with Neighboring Androscoggin Data

Government sampling from three bedrock wells in Androscoggin County over 2011-2012 showed pH levels consistently between 8.0 and 8.5 with a median of 8.2, all within the EPA’s secondary standard. This pH range indicates the aquifer water in this area is mildly alkaline rather than acidic. When comparing to adjacent counties, it’s important not to assume similar values without region-specific testing, as local geology can affect groundwater chemistry. The data underscores that household water sourced from nearby bedrock aquifers may differ significantly in pH.

Distinguishing Acidic Water from Other Common Water Chemistry Concerns

Acidic water should be differentiated from other water chemistry problems such as hardness or mineral staining. Acidic water specifically refers to a low pH that can cause metal leaching and pipe corrosion. Other issues like iron or manganese may cause discoloration but are unrelated to pH levels. Understanding the exact cause of water issues is essential because treatments vary widely. For instance, softening targets hardness minerals but does not correct acidity.

Seasonal and Multi-Year Trends in Local pH Records

Sampling in Androscoggin County’s bedrock aquifer was conducted over approximately one year, capturing a pH range from 8.0 to 8.5. This slight variation suggests stability in pH over different seasons and years within the sampling window. While longer-term variations can occur due to factors like rainfall and recharge rates, the data indicates little risk of encountering significantly acidic water from this aquifer under typical conditions. Households relying on this source can expect consistent pH behavior absent unusual environmental changes.

The Influence of Plumbing Materials and Age on Household Water pH Effects

Even if source water pH is neutral or mildly alkaline, household plumbing materials influence perceived water acidity. Older pipes composed of metals susceptible to corrosion may react adversely to water near the lower or upper ends of the pH range. Plastic or coated pipes generally show fewer reactivity issues. Thus, water chemistry combined with plumbing material and age dictates corrosion risk, staining, and other effects commonly associated with acidic water.

Recommended Test to Confirm Your Water’s Acidity

To determine if acidic water is affecting your household, order a certified laboratory pH test for your own well or water source. A result below 6.5 would indicate acidity outside the typical range found in the regional aquifer samples. This test result is the definitive measure needed to decide on treatment. For managing confirmed acidic water, an Autotrol Acidic / Low-pH Water Filter ships ready to configure and is designed specifically to address low-pH water conditions efficiently for residential use.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2012-08-16. 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 BEDROCK aquifer (Androscoggin County): 9 results from 3 wells, median 8.2 standard units, range 8.0-8.5 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 9 sampled results fell below 6.5
