Is Rain Water Hard or Soft?

It is a tricky question as rainwater absorbs hard minerals when it moves through the ground. However, it remains soft while falling onto the ground. In simple terms, nature produces soft rainwater that becomes hard when it absorbs hard minerals.

Minerals that make rainwater hard water include magnesium and calcium. So if you feel that the rainwater you are having has a corrosive nature, it probably means that you have hard water.   

Is tap water hard or soft?

The answer is: “It depends.” Tap water relies on the quality of your region’s water resources and your local water supply. Some areas tend to have soft water, but it is common to have hard water in your area.

Why is rain water soft water?

Rainwater tends to be soft when it does not contain hard minerals. These include minerals like calcium and magnesium. River water, on the other hand, carries minerals like magnesium and calcium. That’s why river water is classified as hard water, while rainwater is called ‘soft water.’

Rainwater is hard or soft can you tell why? Nature is responsible for the production of rainwater. Rainwater does not contain hard minerals. As a result, you cannot classify rainwater as ‘hard water.’

Disadvantages of Soft Water

The disadvantages of soft water depend on your consumption of the soft water. In simple words, soft water can have some disadvantages if you drink it too much regularly.

It can be detrimental to your body’s salt levels. Abnormal salt levels can result in health problems, such as blood pressure. Soft water can be dangerous if it contains lead. Generally, people install hybrid water softeners or use them with carbon filters to remove unwanted chemicals.

Your soft water is safe for consumption as long as it does not carry high levels of lead. On the other hand, some people do not like to install water softeners when they know that they cannot afford even a small increase in their water bills.

Water softeners lead to a slight increase in your water bill because they produce wastewater. People who install water softeners obviously spend a certain amount of money, and they have to pay for water softener salt, and stuff like that in the long run.  

Is well water hard or soft?

Generally, people do not get soft water as well water. So, if you have well water, it is most likely to be hard water. You can use a commonly available water test kit to determine whether your well water is hard or soft.

Local water testing labs, on the other hand, can provide your detailed water analysis. You just have to submit a sample of your well water to your local water testing lab. However, your local water analysis can be expensive.

In general, the nature of your well water depends on the nature of the water in your region. Some areas do have soft water. So, if your area has hard water, it means that your well water can also have hard water.

Final Thought

Is rain water hard or soft? Rainwater is often classified as soft water until it touches the ground. Nature is responsible for producing soft rainwater. Rainwater becomes hard when it flows through the ground. That’s why river water is often classified as ‘hard water.’

Your rainwater is not likely to have high concentrations of magnesium and calcium. So, if you want to preserve some soft rainwater, you should store it before it touches the ground!


This is my blog about the ways and solutions that can help you improve your health by taking more value from drinking water. As improving health means a lot to me, I decided to create the Water On Top project with the purpose to reveal the benefits of water, the finest products to take our daily water to another level, and much more great stuff about water that I believe is on top of our nutrition.
