Buy NowWhat does government sampling say about acidic water in Ozaukee County's aquifer?
According to US Geological Survey groundwater sampling, wells in Ozaukee County's 100SDGV aquifer showed pH results ranging from 7.1 to 8.0 standard units over a period from August 2013 to August 2024. The median pH was 7.5 standard units based on four samples from one well at about 93 feet depth. None of these results fell below the Environmental Protection Agency's secondary standard lower bound of 6.5, which relates to aesthetics and corrosivity, not safety.
How can acidic water be differentiated from other common water issues in this area?
Acidic water specifically refers to water with pH values below 7, often causing corrosive effects on plumbing and fixtures. In Ozaukee County's sampled aquifer, pH values stayed above 7.0, indicating water was neutral to slightly alkaline rather than acidic. This distinguishes acidic water problems, which may present with low pH and metallic taste or corrosion issues, from problems like hardness or sediment, which arise from different components in water chemistry.
What seasonal or multi-year variations appear in the pH data for this area?
The recorded pH samples from 2013 to 2024 show a relatively narrow range between 7.1 and 8.0 standard units. This limited variation over more than a decade suggests that the aquifer's pH remains fairly stable across seasons and years. Homeowners should not expect wide swings into acidic ranges based on these data but should consider testing their own well water as local conditions can differ.
How do secondary aesthetic standards for pH differ from health-based limits?
EPA secondary standards, such as the 6.5 to 8.5 pH range, address concerns like taste, staining, and corrosion rather than health. These guidelines aim to protect plumbing and improve consumer experience rather than indicate a health risk. The pH measurements in Ozaukee County's aquifer fall within this range, so while water may affect plumbing materials or aesthetics, there's no indication of health-related limits being exceeded.
How can a homeowner interpret the median and range of pH measurements for their own water?
The median pH of 7.5 suggests that typical groundwater from the area aquifer is neither acidic nor strongly alkaline but near neutral. The range from 7.1 to 8.0 shows some variation but all safely within the EPA's secondary guideline. To know their home's actual water pH, a homeowner should conduct a specific test of their supply, since local wells and plumbing conditions can introduce differences not captured by regional data.
How does pH enter groundwater or the distribution system in Ozaukee County?
pH in groundwater is influenced by natural geological formations, soil chemistry, and aquifer characteristics. In Ozaukee County’s 100SDGV aquifer, these factors create a generally neutral to slightly alkaline environment. Water passing through carbonate rocks or soils tends to maintain or increase pH, counteracting acidity. Changes in pH can also arise from surface water interactions and any additives or treatments in municipal distribution systems, though local well water pH is governed primarily by subsurface conditions.
What key details should a homeowner note before seeking advice on acidic water treatment?
- Obtain a certified test of your well or supply water pH to determine your actual water conditions.
- Note any signs of corrosion, staining, or unusual taste that might correlate with low pH.
- Collect any previous water quality reports or maintenance history related to water equipment.
- Be aware of the depth and type of your well to understand how your water source may differ from local aquifer averages.
For households with acidic or low-pH water, the Fleck Acidic / Low-pH Water Filter ships ready to configure and addresses this specific need by balancing pH to reduce corrosivity and protect plumbing. Using measured pH demand data from your own water test helps select the appropriate solution.

Source: USGS groundwater sampling. Sampled 2024-08-05. 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 100SDGV aquifer (Ozaukee County): 4 results from 1 wells, median 7.5 standard units, range 7.1-8.0 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 4 sampled results fell below 6.5
