After drilling a new well, water quality testing confirms that your water is safe for its intended use. While Utah doesn't require
testing for private domestic wells, most lenders and local health departments recommend or require specific tests before occupancy.
Common Testing Requirements
1. Coliform Bacteria
The most common required test checks for coliform bacteria, which indicate potential contamination from surface water or sewage.
A positive result doesn't necessarily mean your water is unsafe, but it does require follow-up testing and potentially well treatment.
2. Nitrates
Elevated nitrate levels can pose health risks, especially for infants. Agricultural areas may have higher nitrate levels due to
fertilizer use. The EPA limit is 10 mg/L for drinking water.
3. Arsenic
Some areas of Utah have naturally occurring arsenic in groundwater. While most wells in Southern Utah have safe arsenic levels,
testing confirms compliance with the EPA limit of 10 μg/L.
4. Total Dissolved Solids (TDS)
TDS measures the total mineral content of your water. Higher TDS can affect taste and leave deposits on fixtures, but isn't
necessarily a health concern. Most wells in our service area produce water with acceptable TDS levels.
County-Specific Requirements
Iron County
The Southwest Utah Public Health Department recommends testing for bacteria, nitrates, and arsenic for new domestic wells.
Many lenders require this testing before financing.
Washington County
Similar requirements to Iron County. The health department offers low-cost testing services and can provide guidance on
interpreting results.
Beaver County
Standard bacteria and nitrate testing is recommended. The more rural nature of the county means less regulatory oversight,
but testing remains important for peace of mind.
When to Test
-
After well completion: Initial testing establishes a baseline for your well
-
Annually: Regular testing catches changes before they become problems
-
After flooding or unusual events: Surface water can contaminate wells
-
If taste or odor changes: Sudden changes may indicate contamination
What If My Water Fails a Test?
Don't panic. Many issues can be addressed with proper well treatment, shock chlorination, or water treatment systems.
