Common water problems in Madison
Perfluorinated chemical problems
PFOA and PFOS are artificial chemicals that were widely used until the year 2000, contaminating drinking water supplies, especially near manufacturing sites. The presence of these chemicals may result in health issues including developmental effects, cancer, liver damage, immune disorders and thyroid imbalance. Learn more about perfluorinated chemicals.
The EPA has set the limit for PFOA and PFOS in drinking water at 70 parts per trillion, but this is only an adversary level and not enforced. This means water providers are not required to test for PFOA and PFOS, and many do not.
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
