Common water problems in Fort Atkinson
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.
Common contaminants include:
- Arsenic
- Turbidity
- Lead
- Nitrates
- Radon
Chlorine water problems
Municipalities often use chlorine to disinfect municipal water supplies, leaving it safe to drink but with a strong smell and taste. Many factors can impact the strength of the chlorine smell - the distance between the public water source and your house, the temperature of the water and how long it's been exposed to air.
Common chlorine water problems include:
- A "bleachy" or swimming pool smell
- A bitter, metallic or disinfectant like taste
- Dry, itchy skin
- Brittle, damaged hair
High iron water problems
Iron enters the water supply from a variety of sources - the soil around private wells, corrosion in the pipes themselves and organically occurring reactions with elements in the water.
Common high iron problems include:
- Rusty, red-brown stains on your fixtures, sinks and tubs
- Rusty stains or residue on laundry
- Yellow, brown, red or orange-colored water
- Metallic tasting water
- Certain foods prepared in water turning black -potatoes and teas are commonly affected
