What pH Levels Mean for Your Home Water

The pH of water indicates its acidity or alkalinity on a scale usually from 0 to 14, with 7 being neutral. Water with a pH below 7 is acidic and can have corrosive properties. The U.S. Geological Survey has sampled groundwater wells in the Escambia County aquifer, measuring pH levels between 4.0 and 7.5 standard units in 15 tests across four wells from mid-2023 to mid-2024. The median pH was 7.1, close to neutral, but some results fell below 6.5.

It is important to note that these measurements reflect a range seen in the local aquifer and not the exact condition of any individual household’s water supply. Only a specific water test on your home’s well or supply can determine its pH.

Implications of Acidic Water at Home

Water with a pH below the Environmental Protection Agency’s secondary standard range of 6.5 to 8.5 may cause aesthetic and material concerns, such as metallic taste, staining, and corrosion of plumbing. These effects arise because acidic water can gradually degrade pipes and fixtures, potentially affecting water quality and property over time.

While this secondary standard guides appearance and maintenance considerations, it is not a health-based limit. Therefore, acidic water does not inherently mean your water is unsafe to drink, but addressing acidity can improve longevity and water experience.

Testing Your Water’s pH and Related Parameters

To make an informed choice between technical treatment approaches, homeowners should conduct comprehensive water testing that includes pH measurement. Knowing your well or tap water’s pH and related characteristics such as total dissolved solids can help pinpoint acidity and its practical impacts.

Periodic testing is advisable if you are drawing water from wells within this aquifer area because pH can vary over time and with depth.

Technical Approaches to Treating Acidic Water

Two common technical strategies for acidic water include chemical adjustment and filtration systems designed to neutralize pH. Chemical dosing can involve adding alkaline substances to raise pH, but it requires ongoing management and careful monitoring to avoid overcorrection.

Alternatively, specialized filters that neutralize water pH operate by passing water through media that chemically balance acidity. This approach is often preferred for whole-house systems, offering consistent treatment without manual dosing.

The Role of a pH Neutralizer Filter

One effective solution documented for acidic water in residential settings is a whole-house pH neutralizer filter. This filter ships ready to configure and uses media that gradually raises water pH into the recommended range. It addresses corrosion by reducing acidity contact with plumbing and appliances.

While it cannot predict your household water’s exact pH, using a neutralizing filter after confirming acidic conditions through testing helps protect your home’s water system and improve water taste and appearance.

Summary

• Escambia County aquifer wells show a pH range of 4.0 to 7.5, with some acidic results below 6.5.
• This pH range is a secondary standard indicator, relating to water aesthetics and corrosion potential, not safety.
• Individual home water pH must be tested to determine treatment needs.
• Technical options include chemical dosing and neutralizing filtration systems.
• The documented pH neutralizer filter provides a consistent and maintenance-friendly way to reduce water acidity and its effects.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2024-07-17. 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 aquifer (Escambia County): 15 results from 4 wells, median 7.1 standard units, range 4.0-7.5 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 3 of 15 sampled results fell below 6.5
