Common water problems in Delavan
Contaminant problems
Some of the most dangerous water contaminants have no taste, smell or appearance. Contaminants can enter your water via private wells, miles of underground utility pipes or even the local municipal water source. Learn more about water contaminants.
Common contaminants include:
- Arsenic
- Turbidity
- Lead
- Nitrates
- Radon
Hard water problems
Hard water results from high levels of calcium and magnesium in water. Hard water minerals stick to everything water touches, and do more than leave an unsightly residue - they can actually harm your home and cost you money. Learn more about hard water.
Common hard water problems include:
- Stains and buildup on sinks, shower heads, and dishes
- Dry skin and hair
- Costly long-term damage to water appliances
Smelly water problems
Before your water enters your home, it can pick up smelly contaminants - from the soil around private wells, miles of underground utility pipes or even the local municipal water source itself. You may not be able to see these contaminants, but as soon as you turn on the tap or lift a glass to your face, something is obviously not right. Learn more about smelly water.
Common water odor problems include:
- A "rotten-egg" odor due to hydrogen sulfide in the soil near your well
- A musty, woody smell due to organic contaminants like algae or total dissolved solids (TDS)
- A "bleachy" smell due to chlorine added in by municipalities
- A soapy or chemical smell due to contaminated private wells

Culligan in Delavan installed a new water softener when we purchased our last home. It worked perfectly and they always delivered salt on time when needed.

Contacted Delavan Culligan late Friday afternoon with a problem with an off brand softener. I had company coming this weekend and they had a service man here within the hour with the parts to fix my softener. 45 minutes later my unit was working properly. Service man friendly and knowledgeable. I would highly recommend these guys.
