Water hardness is a common issue that affects many households across the United States. It can cause scaling, clogging, and damage to plumbing, appliances, and skin. But how do you know if your water is hard or soft? One way to check is by using a water hardness map or by looking up the water hardness level in your area by zip code.
What is Water Hardness?

Water hardness is a measure of the amount of minerals, particularly calcium and magnesium, present in water. Hard water contains high levels of these minerals, which can cause scaling and clogging in pipes and appliances. Soft water, on the other hand, has low levels of these minerals.
Effects of Hard Water
Hard water can have several negative effects on your household, including:
- Scaling and clogging of pipes and appliances
- Damage to skin and hair
- Increased energy bills due to reduced appliance efficiency
- Reduced water pressure
- Unpleasant taste and odor
How to Check Water Hardness by Zip Code

There are several ways to check the water hardness level in your area by zip code. Here are a few methods:
- Use an online water hardness map: Many websites, such as the US Geological Survey (USGS), provide interactive maps that show the water hardness levels in different areas.
- Contact your local water utility: Your local water utility may be able to provide information on the water hardness level in your area.
- Use a water testing kit: You can purchase a water testing kit online or at a local hardware store to test the water hardness level in your home.
Water Hardness Levels by Zip Code
