5 Facts About Your Well Water You Need to Know

Mosman Well Works • May 6, 2025

If you’re considering installing a well water system on your property, there are a few important facts every homeowner should understand. While having your own water source offers independence and long-term savings, it also comes with unique responsibilities. Knowing how to maintain your well and improve water quality will help keep your household safe and your system running efficiently. Here are five key things you need to know about owning a private well.

1. Well Water Is Usually Hard

Groundwater is a powerful natural solvent, which means it easily dissolves minerals from surrounding soil and rock. The most common minerals in well water are calcium and magnesium, which contribute to water hardness. If you live in an area with mineral-rich soil, chances are you’ll need a water softener system to prevent buildup on appliances and plumbing. Consider scheduling a free water quality analysis to identify the right solution for your home.

2. Well Water Can Cause Staining

High levels of iron in well water can cause noticeable staining on toilets, sinks, and bathtubs. Even your glassware, silverware, and laundry can develop dull or orange stains from iron or hard water. While iron isn’t a major health concern, it can alter the taste of your water and be difficult to clean once staining sets in. Installing a specialized iron filtration system can help eliminate this issue and improve both water taste and appearance.

3. Well Water Must Be Tested Annually

To protect your health and home, it’s essential to test your well water at least once a year. The EPA recommends annual testing for E. coli and coliform bacteria, as well as periodic testing for minerals like iron, manganese, nitrates (especially important for pregnant women), arsenic, radon, and volatile organic compounds. If you notice changes in your water’s color, taste, or smell, you should have it tested immediately. Regular testing ensures your well water stays safe for drinking, cooking, and bathing.

4. Wells Do Not Freeze Easily

It’s a common misconception that well water freezes in winter, but in reality, most wells and their components are buried well below the frost line. However, the pipes connecting your well to your home can be vulnerable to freezing temperatures. To protect these lines, use foam insulation sleeves and call a professional if you experience low water pressure or suspect frozen pipes. A pro can also winterize your system to prevent costly damage during cold months.

5. Purifying Your Well Water Beats Buying Bottled Water

Filtering and purifying your well water is not only better for your health but also better for the environment. By reducing plastic waste and cutting out the cost of bottled water, you’ll save money and minimize your environmental impact. In fact, over 25% of bottled water sold in the U.S. is simply purified tap water. With a proper filtration system, you can enjoy fresh, clean well water right from your tap.
