Water Hardness in Madison, WI: What You Need to Know

Madison, Wisconsin, is known for having moderately hard water. This means the water contains a significant amount of dissolved minerals, primarily calcium and magnesium. While not a health concern, hard water can affect things like soap effectiveness and plumbing.

What is Water Hardness?

Water hardness is a measure of the dissolved minerals, specifically calcium and magnesium, in water. The higher the concentration of these minerals, the harder the water is considered to be. Hardness is usually expressed in grains per gallon (gpg) or parts per million (ppm). You can learn more about water hardness on Wikipedia.

Madison’s Water Hardness Levels

Madison’s water hardness fluctuates slightly depending on the source. Generally, Madison’s water hardness is considered to be in the moderately hard range, typically falling between 10-15 gpg (171-256 ppm). The city obtains its water from deep sandstone aquifers. Because this water has been underground longer it has more contact with materials containing calcium and magnesium and that is why it is moderately hard.

Effects of Hard Water

Hard water doesn’t pose a health risk, but it can have some noticeable effects:

• Soap Scum: Hard water reduces the effectiveness of soaps and detergents, leading to soap scum on surfaces like sinks, showers, and bathtubs.
• Scale Buildup: Mineral deposits can accumulate inside pipes, water heaters, and appliances, reducing their efficiency and lifespan.
• Dry Skin and Hair: Some people find that hard water can contribute to dry skin and hair.
• Spotty Dishes: Hard water can leave spots and streaks on dishes and glassware after washing.

Dealing with Hard Water

If you are concerned about the effects of hard water, there are several solutions available:

• Water Softeners: These devices remove calcium and magnesium from the water supply, effectively softening the water.
• Water Filters: Some water filters can reduce the concentration of minerals in water, although they may not soften it completely.
• Using More Soap: Compensating with more soap and detergent in washing machines and dishwashers can improve cleaning performance.
• Cleaning Products: Specific cleaning products are designed to tackle soap scum and mineral deposits.
