Common Water Contaminates

While certain water contaminants, like iron, sulfur, and total dissolved solids, are easy to spot by residue, odor, and discolored water, other potentially harmful contaminants, like arsenic and lead, can go undetected by the senses. Learn more about common water contaminants, find out how a Culligan lab-certified water test can detect these water contaminants, and see how your Culligan Water Expert can identify a solution to target and treat your water. 


Arsenic in Water

Arsenic is one of the more dangerous water contaminants because it is both odorless and tasteless, becoming more toxic over time. Although it can be hard to detect, there are some factors that can help you determine if your water might be at risk for contamination. Learn more

iron in water

Iron in Water

Iron in water can cause real damage throughout your home – appliances begin to wear down over time, and limescale buildup and mineral deposits slow down their efficiency, requiring more energy to run. Learn more

lead in water

Lead in Water

Levels of lead in drinking water and tap systems can often pass unnoticed, as it is virtually undetectable to the senses. If you suspect your water is contaminated with lead, start using bottled water for drinking and cooking. Learn more

nitrates in water

Nitrates in Water

Commonly found in many water tables, nitrates are naturally occurring, but can be problematic beyond a certain concentration. Nitrates in water can adversely affect certain populations, like young children and the elderly, and are next to impossible to identify in water without a test. Your Culligan Water Expert can perform an at-home water test, discuss the concentration levels with you, and make recommendations for treatment. Learn more

PFOA PFOS in water

Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA) in Water

Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA) are fluorinated organic chemicals that have leached into water supplies. These Perfluorochemicals (PFC’s) are hazardous to the environment and are concerning for our health. Your Culligan Water Expert can test for the presence of these PFC’s in your drinking water. Learn more

sulfur in water

Sulfur in Water

The telltale sign of sulfur in water is that unpleasant rotten-egg smell. If that’s not enough, its presence can also be a breeding ground for bacteria, which can lead to problems with plumbing and appliances that can eventually corrode pipes and fixtures. Learn more

total dissolved solids in water

Total Dissolved Solids (TDS) in Water

Total dissolved solids exist in water naturally after it filters through bedrock and soil. Although a certain amount in water is normal, problems start when levels of TDS increase beyond what would accumulate naturally. Learn More
