What Is Added To The Tap Water On Maui?

Makawao, Pukalani, Lower Kula, and Upper Kula all have soft water while the groundwater on other parts of the island is harder. Many visitors comment on how Maui’s water tastes like minerals. 

The pH levels of the water vary depending on what district you’re in.

However, on average, the pH level can range from 7.2 to 9.1, with water in Makawao being slightly more acidic compared to water in Kula.

What Does Maui Drinking Water Taste Like?

Many visitors comment on how tap water on Maui tastes like minerals. However, your own tastes will vary, depending on where you’re from and the kind of water you’re used to drinking.

If you don’t particularly like the taste of chlorinated water, then you should put your water in a container and sit that container in the refrigerator overnight. The water should taste less like chlorine in the morning. Or, you might want to filter water through a Brita filter. 

The taste and odor of Maui drinking water may change slightly sometimes. There are different minerals found in minute quantities in the aquifers which alter the taste.

Your water may taste differently if the place you are staying has older or newer pipelines installed. Also, during hot temperatures and heavy storms, the taste of water may change slightly, but it doesn’t affect the safety of the water unless the Water Supply agency issues a statement saying so. 

Is There Any Hawaiian Island Where Tap Water Isn’t Safe?

For the most part, Hawaii tap water is completely safe to drink.

The state prides itself on the taste of its tap water, as it comes from rainwater that’s been naturally filtered through underground volcanic rock before it reaches the aquifers.

However, there could be a few extremely remote places in Hawaii where the tap water is not safe to drink, such as Niihau (westernmost main island) and Kahoolawe (unpopulated island)  however, residents or business owners will be able to advise you of what you should do when visiting.
