The groundwater in Salt Lake County primarily comes from the 100VLFL aquifer, feeding many residential wells and water systems. Water from this aquifer can vary in quality as it flows through soil and rock before reaching household taps. Understanding nitrate levels in this aquifer helps clarify what your water might contain, even if your current equipment struggles to keep up.
How the treated water differs at the tap once the documented technology is in place
When the Fleck Nitrate & Nitrite (Well) Filter system is configured for your home, it is designed to specifically reduce nitrate and nitrite concentrations from your water supply. This system works by filtering these compounds out, resulting in water that is improved in terms of nitrate content. Over time, this can ease stress on existing equipment that may have difficulty maintaining low nitrate levels alone. Water treated by this approach typically shows reduced nitrate and nitrite levels, which can be verified through your own water testing.
How to compare this area's record with a neighbouring county's without overreading it
Salt Lake County’s nitrate data reflects samples taken from wells of varying depths, between 23 and 1385 feet, over more than a decade. When looking at neighbouring counties, it’s important to recognize each area has distinct groundwater characteristics, sampling approaches, and land use influences. Thus, while Salt Lake County’s aquifer median nitrate-related nitrite is 0.004 mg/L with a detected range up to 0.067 mg/L, comparing this directly to adjacent counties without considering those factors can lead to assumptions that might not apply locally. Differences in geology, agriculture, and well depth can cause nitrate levels to vary significantly.
What the measured range means against the relevant federal standard, and what it does not mean
The samples from Salt Lake County’s 100VLFL aquifer show nitrite detections well below any federal maximum contaminant level. There has been no result in this data set that exceeds the federal threshold for nitrite concentration in drinking water. However, a detection signifies that nitrite was measurable by instruments, not that it violates any safety standard. This distinction is critical: presence alone is not a health violation or a safety concern. Rather, any concern about your water’s nitrate or nitrite levels requires individual testing of your own water source.
The role of plumbing material and age, separate from the source water
While source water nitrate and nitrite concentrations come from the aquifer, plumbing materials and the age of your household plumbing system can affect water chemistry too. Older pipes or certain materials might interact with water, potentially altering taste or contributing secondary effects unrelated to nitrate itself. This means that some water quality issues may stem from within the distribution system inside your home rather than from the aquifer source. Proper monitoring includes checking both the source water and your home’s plumbing conditions.
What 'detected', 'median' and 'range' mean in the sampling record on this page
- Detected: Nitrite was measurable above the reporting limit in 32 out of 164 samples. This means instruments found it present but does not imply any violation.
- Median: Half the samples showed nitrite levels at or below 0.004 mg/L, indicating generally low concentrations in the aquifer.
- Range: Nitrite levels in detected samples varied from 0.001 to 0.067 mg/L, reflecting variation across different wells and depths over time.
This sampling record covers 48 wells within Salt Lake County’s 100VLFL aquifer collected over eleven years, providing a broad perspective but not a direct measurement of any individual well’s water. For your home's water condition, a dedicated sample test is necessary.
These nitrate and nitrite measurements are sourced from the United States Geological Survey groundwater monitoring at https://waterdata.usgs.gov/monitoring-location/403943111575701/, detailing extensive sampling efforts in this region’s aquifer.

Source: USGS groundwater sampling. Sampled 2021-12-08. 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.
