View full details

The U.S. Geological Survey collected 912 pH measurements from 187 wells in the Yakima County aquifer between 2014 and 2025. The results ranged from 6.4 to 8.6 standard units with a median of 7.6. The EPA's secondary standard for pH, focused on aesthetic and corrosivity concerns, spans 6.5 to 8.5, and only one sample fell below 6.5. This data shows the variability of acidity and alkalinity in the area but does not specify any individual household water condition.

Fixtures and Appliances First Affected by Acid and Hardness

Tap Water Fixtures Show Corrosion Signs

Lower pH near or below 6.5 in water can lead to subtle corrosion on metal faucets and pipes. Discoloration or a metallic taste may be initial clues of acidic water effects.

Water Heaters Experience Scale Buildup

Hardness minerals such as calcium and magnesium can accumulate inside water heater tanks, reducing efficiency and lifespan through scale formation.

Appliances Using Water May Have Reduced Longevity

Dishwashers and washing machines exposed to hard water often show wear from mineral deposits, potentially increasing maintenance needs.

How the Documented Treatment Technology Removes or Neutralizes the Constituent

Neutralizing Acidity with Precise pH Adjustment

The Fleck Acidic Water + Hard Water (Well) System adjusts water pH toward neutral, mitigating the corrosive nature of acidic water in household plumbing.

Hardness Minerals Are Reduced by Ion Exchange

This system removes hardness minerals up to its 32,000 grain capacity, which helps prevent scale buildup and related issues in appliances and fixtures.

Continuous Water Conditioning for Balanced Quality

By addressing both acidity and hardness simultaneously, the system supports long-term improvements in water quality and household infrastructure preservation.

Why Aesthetic Secondary Standards Differ from Health-Based Limits, Applied to This Constituent

EPA pH Standards Are Focused on Appearance and Corrosion, Not Health

The EPA secondary standard pH range (6.5 to 8.5) guides water quality for taste, staining, and pipe integrity, but does not indicate safety for drinking.

Variations Outside This Range Do Not Automatically Indicate Health Risks

Sampling below or above this pH range in Yakima County does not imply a health hazard; it signals potential aesthetic or infrastructure concerns.

Hardness Levels Affect Usage More Than Safety

Hardness minerals influence water feel and scaling but are not federally regulated as health risks.

What a Certified Laboratory Test for This Constituent Reports and How to Read It

pH Measurements Show Acidity or Alkalinity in Standard Units

Tests report pH as a number typically between 0 and 14; values under 7 indicate acidity and above 7 alkalinity.

Hardness Is Measured Usually in Grains per Gallon or mg/L

This measurement quantifies calcium and magnesium levels, helping assess potential scale formation.

Certified Lab Reports Provide Precise Figures Unique to Your Water

Your home's water test results are required to determine the actual acid and hardness levels, as area averages do not predict individual conditions.

This ensures advice is based on your specific water profile.

Note All Visible Water Effects and Appliance Concerns

Documenting stains, corrosion, or scale buildup helps identify the best treatment focus.

Record Well Depth and Source Type If Known

These details provide context for water quality variations and treatment suitability.

What You Should Not Conclude from Area Data

The Yakima County aquifer sampling reflects a regional snapshot that does not establish your well or tap water's exact acidity or hardness. Detecting pH values outside secondary standards in the area does not mean your water is corrosive or unsafe. To understand your home's water quality and select an appropriate treatment, certified testing of your supply is essential. The Fleck Acidic Water + Hard Water (Well) System ships ready to configure and is designed to address both acidity and hardness effectively when matched to your water conditions.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2025-09-11. 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 (Yakima County): 912 results from 187 wells, median 7.6 standard units, range 6.4-8.6 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 1 of 912 sampled results fell below 6.5
