Many assume acidic water means health risks, but what does the official pH record actually indicate?
The U.S. Geological Survey has sampled Kitsap County aquifer wells from June 2010 to August 2024, measuring pH in 176 results from 43 wells. The recorded pH ranges from 5.8 to 8.6 standard units with a median of 6.9. While 45 out of 176 results fell below the EPA's secondary aesthetic pH threshold of 6.5, these values reflect corrosivity and taste concerns, not a health violation.
Is water pH stable throughout the year or does it fluctuate? What can the multi-year record tell a homeowner?
The sampling dates spanning over 14 years show that pH variation in Kitsap County aquifer is real but generally contained within the range of approximately 5.8 to 8.6. This variability accounts for seasonal shifts, rainfall influences, and other natural aquifer changes, meaning water acidity levels may shift over time rather than remain constant.
How reliable are the pH findings for guiding household treatment decisions?
The pH data rests on 176 measurements from 43 separate wells, each 12 to 50 feet deep. This sample size provides a robust regional overview of aquifer water conditions but does not specify any single home's water. To know household water pH precisely, a direct test is necessary. Regional data guides expectations and helps decide the class of water treatment needed.
How does the Fleck Acidic / Low-pH Water Filter technology address acidic water?
The Fleck System uses a tailored approach to neutralize low pH water, raising acidity levels to a range that reduces corrosivity without impacting water safety. This treatment helps protect household plumbing and appliances prone to damage from acidic water and improves aesthetic qualities such as taste and potential staining.
What do the median and pH range mean when read as a homeowner in Kitsap County?
With a median pH of 6.9, most aquifer water samples are near neutral, but a significant portion falls below the aesthetic threshold of 6.5. Homeowners experiencing issues linked to water acidity—like blue-green stains or metal corrosion—should consider the Fleck System. However, confirmation via household water testing ensures treatment matches actual conditions.
Do large households, second homes, or seasonal properties require different considerations?
While the general pH range applies broadly across the Kitsap aquifer, water usage patterns and seasonal occupancy can affect treatment needs. Larger households may need higher capacity systems configured to maintain pH balance continuously. Seasonal properties might require treatment setups optimized for intermittent use without compromising protection during periods of inactivity.
Understanding the official pH range documented by the U.S. Geological Survey for Kitsap County aquifer water helps homeowners make informed treatment choices. This record covers 176 pH results from 43 wells sampled between 2010 and 2024. For full details, see the government source at waterdata.usgs.gov.

Source: USGS groundwater sampling. Sampled 2024-08-19. 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 (Kitsap County): 176 results from 43 wells, median 6.9 standard units, range 5.8-8.6 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 45 of 176 sampled results fell below 6.5
