Hard Water Smelly Water Contaminants

Common water problems in South Glengarry

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

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.

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.

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
