Why Does Well Water Have White Residue? [Treatment Included]

The most common well water problem is a white residue on appliances, plumbing fixtures, crockery items, and even clothes. Though it may seem frustrating and tough to remove, most white residue problems can be fixed if you know how to do it.

well water leaves a white residue and how to fix it.

Common Causes for White Residue with Well Water

The primary reason behind white residue from well water is a high concentration of minerals like calcium and magnesium. These two also make your water hard. The white residue on your appliances, plumbing fixtures, bathtubs, and laundry is due to hard water.

Calcium and magnesium enter well water as a result of underground water movement. These minerals are present in soil and rocks. Moreover, calcium and magnesium are soluble elements in water and hence cannot be removed with a sediment filter.

Other minerals like sodium, potassium, phosphorous, and fluoride can also cause white buildup on your taps. Though it happens rarely, it is worth knowing.

Higher iron levels in well water can also leave stains on your appliances. Iron enters well water underground or through rusted plumbing pipes in your home.

How can I Identify what’s causing the White Scale on my Appliances?

A water test is the only reliable way to identify the culprits behind a white residue. A water test will also calculate the hardness level in your water so you can select the right treatment unit.

The EPA recommends annual testing for private wells so you can modify your water treatment options accordingly.

How to Treat White Scale from Well Water

White residue/limescale looks awful and can damage your appliances if not treated. There are two ways to deal with this problem. Let’s check out both.

Instant Remedy

You can use a DIY cleaning solution or a commercial cleaner to remove white residue from faucets, taps, showerheads, toilets, and appliances. These cleaners work instantly by removing the deposits but do not guarantee prevention.

Long Term Solution

The best way to deal with these stains is to install a water softener at your home. There are two types of water softeners; salt-based or salt-free (water conditioner).

Salt-Based Water Softeners: These machines utilize a softening salt to remove calcium and magnesium from your well water. The process is known as ion exchange as it replaces calcium and magnesium with sodium or potassium. A salt-based water softener regenerates periodically and requires a discharge arrangement. Please note that some states prohibit salt-based water softeners, so check local laws before buying one.

SpringWell’s salt-based water softener is a costly but reliable and 100% effective way to make well water soft. The unit has a separate brine tank for better performance and easy maintenance.

You can manage the unit through the Bluetooth control head and set it to automatic regeneration. The softener can make extremely hard water soft. It is easy to install and can be paired with a whole-house water filter or a UV purifier.

Salt-Free Water Softeners: A salt-free water softener is also known as a water conditioner. A water conditioner doesn’t remove or add anything to water; it changes how water interacts with other surfaces. A water conditioner uses magnetic force to crystallize calcium and magnesium in water, so they don’t stick to surfaces. Please note that water conditioners do not eliminate the stains; they just reduce them.

Is it safe to drink water with calcium in it?

Yes. Your body needs calcium for bone growth and tissue development. Hence, it is 100% safe to drink water with calcium in it.

Is hard water bad for your health?

Hard water isn’t bad for your health as it contains calcium, magnesium, and iron. All three are required by your system for proper functioning and growth. However, these minerals can wreak havoc on your plumbing fixtures and appliances.
