What is Water Hardness?

Water hardness refers to the presence of minerals, primarily calcium and magnesium, in your water. These minerals are picked up as water passes through rocks and soil, resulting in varying levels of hardness. Understanding water hardness is crucial for maintaining the quality of your water and the efficiency of your appliances.

How is Water Hardness Measured?

Water hardness is measured using units such as parts per million (PPM) or grains per gallon (GPG).

To help you understand the different levels of water hardness, we’ve provided a scale:

Water Hardness LevelPPM (Parts Per Million)GPG (Grains Per Gallon)
Soft0 – 170 – 1
Slightly Hard17 – 601 – 3.5
Moderately Hard60 – 1203.5 – 7
Hard120 – 1727 – 10
Very Hard172+10+

Water Hardness Map

In addition to our tool, you can also check out water hardness map. A water hardness map is a valuable tool that allows residents and businesses to understand the local water quality in their area. These maps are usually created and provided by water treatment authorities or environmental agencies. They display water hardness levels across a region, often using a color-coded scale for easy interpretation. For example this US Water Hardness Map is a valuable shortcut to assess water hardness if you are living in US.

Knowing Your Water Hardness Level: The Benefits

Knowing the hardness level of your water can have numerous benefits. It allows you to:

  1. Protect Your Appliances: Hard water can cause limescale buildup in your appliances, reducing their efficiency and lifespan. By knowing your water hardness level, you can take preventive measures to protect your appliances.
  2. Improve Water Quality: Hard water can affect the taste and odor of your water. By understanding your water hardness level, you can explore water treatment options to improve the overall quality of your water.

Causes of Water Hardness

Water hardness is primarily caused by the presence of certain rocks and minerals in the ground. When water comes into contact with these rocks and minerals, it picks up the dissolved minerals, resulting in varying levels of hardness.

Effects of Hard Water

Hard water can have several negative effects on your daily life and household. Some common problems associated with hard water include:

  • Skin and hair problems: Hard water can cause dryness, itchiness, and irritation of the skin and scalp. It can also make your hair look dull and lifeless.
  • Stains and buildup: Hard water can cause stains on clothes, dishes, and other surfaces. It can also lead to mineral buildup in pipes, appliances, and fixtures.
  • Increased cleaning time: Hard water can make cleaning more difficult and time-consuming. Soap scum and mineral buildup can be tough to remove, requiring more cleaning products and elbow grease.
  • Higher energy bills: Hard water can reduce the efficiency of water heaters, dishwashers, and washing machines. This can lead to higher energy bills and more frequent repairs or replacements.
  • Health risks: While hard water is not harmful to drink, it can contain high levels of minerals that may contribute to kidney stones or other health problems over time

Managing Water Hardness

Water Softeners

One effective solution for managing water hardness is the use of water softeners. These devices work by removing the minerals that cause hardness, resulting in softer water. The benefits of using water softeners include improved appliance longevity and enhanced water quality.

Alternative Solutions

In addition to water softeners, there are other methods to address hard water issues. Descalers and specific treatments for limescale can also be effective in reducing the negative effects of hard water. While these alternatives may not completely eliminate water hardness, they can provide temporary relief and improve water quality.

Yes, we source our water hardness data from reliable and official sources to ensure accuracy and currency. However, we recommend checking the most recent reports for the most up-to-date information.

What can I do if I find out that my area has hard water?

If you discover that your area has hard water, there are several solutions available. One common method is installing a water softener. You can also explore alternative treatments, such as water descalers, to manage hard water-related issues effectively.

What is a normal water hardness level?

A normal water hardness level can vary, but it’s typically classified as follows:
Soft: 0 – 17 parts per million (PPM) or 0 – 1 grains per gallon (GPG).
Slightly Hard: 17 – 60 PPM or 1 – 3.5 GPG.
Moderately Hard: 60 – 120 PPM or 3.5 – 7 GPG.
Hard: 120 – 172 PPM or 7 – 10 GPG.
Very Hard: 172+ PPM or 10+ GPG.
The specific definition of “normal” may depend on your location and personal preferences, but these ranges provide a general guideline.

Is 47 ppm hard water?

A water hardness level of 47 parts per million (PPM) falls within the “Slightly Hard” category. While it is not extremely hard, it is considered moderately hard and may lead to some of the common issues associated with hard water, such as limescale buildup.

Is 90 ppm hard water?

A water hardness level of 90 parts per million (PPM) also falls within the “Slightly Hard” category. It is moderately hard and can lead to similar issues as mentioned earlier, such as limescale buildup.

Is 300 ppm hard water?

A water hardness level of 300 parts per million (PPM) falls within the “Hard” category. This is considered hard water, and you may experience more pronounced problems related to hard water, including increased limescale buildup.

Is 100 ppm water safe to drink?

A water hardness level of 100 parts per million (PPM) is generally considered safe to drink. Water hardness levels primarily affect the taste and texture of the water but are not typically associated with health risks. Most drinking water standards focus on contaminants and impurities other than water hardness.

Is 200 ppm water safe?

A water hardness level of 200 parts per million (PPM) is also generally safe to drink. Similar to 100 PPM, water hardness levels of this magnitude are not typically associated with health concerns but can affect the taste and texture of the water.
