Common water problems in Watertown
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
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. Learn more about high iron 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
