Well Water Testing
Sample kits are available for free at the Kandiyohi SWCD office. Instructions included with each kit enable you to collect your own sample from home; a fee schedule can be found in the test kit.
Minnesota Department of Health (MDH) recommends:
- Coliform Bacteria (every year)
- Nitrate (every other year)
- Arsenic (at least once)
- Lead (at least once)
- Manganese (before a baby drinks the water)
Minnesota Department of Health recommends:
Inspect your well regularly.
- Damage: Any cracks or holes in well casing, corrosion, loose wires, or soil settling?
- Well cap: Is it securely attached to the well casing? Is it broken or missing?
- Connections: Are the electrical conduit and other connections watertight?
Protect your well.
Do these things:
- Keep top of well at least 1-foot above ground.
- Keep well area clear of debris.
- Maintain minimum isolation distances from contamination sources (see isolation distances image above).
- Mark your well with flags or posts to protect it from being hit by vehicles or machinery.
- Take precautions before and after floods.
Do NOT do these things:
- Allow water to pond around your well.
- Use, store, or dispose of potential pollutants (such as animal wastes, fertilizers, pesticides, or hazardous chemicals) near your well.
- Tie animals to your well.
- Dispose of waste in unused wells.
Seal unused wells.
Kandiyohi SWCD shares costs of sealing unused wells - contact us for more information.
A well that you no longer use (unused well) can be a pathway for contaminants to get into groundwater and is a safety hazard. You are responsible for getting unused wells on your property sealed. Only a licensed well contractor can legally seal wells.
Contact a licensed well contractor if your well needs to be repaired or sealed.
