Common Belief: You Can Know Your Water Quality from Nearby Well Data Alone

Many homeowners think that sampling data from area wells directly describes their own water. In Navajo County, aquifer 220NAVJ, U.S. Geological Survey data from 14 wells sampled between 2010 and 2019 shows chloride was detected in all 40 samples, with a median level of 3.79 mg/L and a range from 1.67 to 117.0 mg/L. However, these figures reflect the aquifer generally, not your specific well or household water. Individual water testing is necessary to know your home's exact conditions.

Common Belief: Public Water System Records and Private Wells Offer the Same Information

Public water systems often maintain detailed records that include health-based compliance data, whereas government aquifer sampling like that for Navajo County reports constituent concentrations without establishing safety or violations. The U.S. Geological Survey measurements show no federal thresholds were exceeded in these chloride samples, which means they are not health violations or unsafe levels but simply detections in groundwater over a range of depths from 554 to 3,737 feet. For private wells, only direct testing of your own well water can establish your home's water quality status.

Commercial or Industrial Operators Need More Complex Water Data Than Residential Households

While households focus mainly on taste, staining, and general water clarity, commercial and industrial users often require information on water chemistry that affects processes or equipment longevity, such as hardness, corrosivity, or specific contaminants. In Navajo County's aquifer, the chloride range does not indicate a safety concern but could contribute to taste or mineral buildup considerations. Residential users primarily benefit from understanding overall water quality and addressing any aesthetic or maintenance issues through appropriate treatment.

Example Interpretation of Median and Range: What Groundwater Data Means to a Homeowner

If your well is in Navajo County drawing from aquifer 220NAVJ, the median chloride level of 3.79 mg/L and a maximum observed level of 117.0 mg/L in area samples indicate variability in the aquifer. Chloride at these levels supports typical aquifer conditions without surpassing any federal health thresholds. This range explains why some homes might notice a slight saline taste or minor mineral stains but not a health hazard established by regulation. Your own water test can confirm where your well sits within this range.

How Seasonal and Multi-Year Sampling Paints a Reliable Regional Picture

The U.S. Geological Survey collected data over nearly a decade (2010–2019), capturing natural variations in groundwater quality. This long-term sampling indicates consistent chloride detection across Navajo County wells but with fluctuations in concentration. Seasonal or year-to-year changes can influence water composition but within ranges typical for the aquifer. Recognizing these patterns helps homeowners anticipate normal variation versus unusual spikes that might require treatment.

To definitively know your home's water quality, order a comprehensive water test that measures chloride and other relevant constituents. This test is key to deciding if treatment addressing total well water issues is needed. Equipment such as the Fleck Total Well Chlorination System ships ready to configure and can manage common well water quality factors effectively, supporting cleaner, more reliable water for your household.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2019-08-23. 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 Chloride in the 220NAVJ aquifer (Navajo County): 40 results from 14 wells, median 3.79 mg/L, range 1.67-117.0 mg/L; none above any federal threshold
