Juab County, UT
These figures come from wells tested in Juab County, UT, not from any one well.
- Sulfate is common in wells in Juab County, UT (40 of 134 tested wells were over that level), so it's worth testing for.
- Iron and manganese are not common in wells in Juab County, UT (0 of 22 and 1 of 24 tested wells were over). Only a test tells you about your own well.
- Wells in Juab County, UT are typically very hard (135 wells tested).
- Only a test of your own well tells you about your water.
What to test for
Start with the four this site covers:
- sulfate (common in wells here)
- iron
- manganese
- hardness
Most well owners also test for these. We point to the source and don't interpret the results.
- arsenic: occurs naturally in groundwater in many regions. USGS: arsenic and drinking water
- nitrate: common near farmland and septic systems. EPA: private drinking water wells
- total coliform bacteria: the standard yearly well check. EPA: private drinking water wells
- lead and copper: from household plumbing, especially when pH is below 6.5. EPA: lead in drinking water
- PFAS: several states run private-well sampling programs. EPA: PFAS
- a certified lab: states certify labs and some run their own private-well programs. Utah's certified-lab list (from your state drinking-water program)
The numbers
County figures describe the wells sampled there, not any one well. Exact counts, sample years and sources are below.
Iron Recent
| Level it's compared with | 0.3 mg/L |
|---|---|
| Share of wells over the level | 0.0% |
| Wells over the level / wells judged | 0 of 22 |
| Median | < DL mg/L |
| Years sampled | 1957–2021 |
| Wells | 23 |
| Test results | 182 |
| Wells left out | 7 |
| Sources | USGS (72), UTAHDWQ_WQX (14), UTAHGS (2) |
More than half the wells had results below the lab's detection limit, so the median is reported as below that limit.
Manganese Recent
| Level it's compared with | 0.05 mg/L |
|---|---|
| Share of wells over the level | 4.2% |
| Wells over the level / wells judged | 1 of 24 |
| Median | < DL mg/L |
| Years sampled | 1957–2021 |
| Wells | 25 |
| Test results | 178 |
| Wells left out | 7 |
| Sources | USGS (68), UTAHDWQ_WQX (12), UTAHGS (4) |
More than half the wells had results below the lab's detection limit, so the median is reported as below that limit.
Hardness Recent
| Level it's compared with | none; hardness is shown in bands |
|---|---|
| Share of wells very hard | 93% |
| Median | 460 mg/L as CaCO₃ |
| Years sampled | 1950–2021 |
| Wells | 135 |
| Test results | 316 |
| Wells left out | 8 |
| Sources | USGS (113), UTAHDWQ_WQX (14), UTAHGS (8) |
Sulfate Recent
| Level it's compared with | 250 mg/L |
|---|---|
| Share of wells over the level | 30% |
| Wells over the level / wells judged | 40 of 134 |
| Median | 119.75 mg/L |
| Years sampled | 1950–2021 |
| Wells | 134 |
| Test results | 316 |
