Question 1

How often should private well water be tested?

Accepted Answer

At minimum, test annually and any time you notice a change in taste, color, or odor. Many well owners also test after flooding, repairs, or new construction near the well. Your best test panel depends on local risk factors and what contaminants are common in your area.

Question 2

How do I know if my well has bacteria or coliform?

Accepted Answer

You usually can’t tell by taste, smell, or appearance, so testing is the right next step. Coliform presence indicates pathways where contamination may be entering, and follow-up testing may be recommended. If confirmed, treatment options can include purification methods matched to your results and system type.

Question 3

Can old plumbing cause bad-tasting or discolored water?

Accepted Answer

Yes, corrosion, scale, and sediment buildup in older pipes can affect both taste and color. Discoloration after water sits overnight often points to plumbing-related issues. Testing and a basic inspection help determine whether treatment, pipe repair, or both are the best path forward.

Question 4

Why does my water taste earthy or musty?

Accepted Answer

Earthy or musty tastes can come from organic compounds, algae-related compounds, or seasonal changes in the water source. Carbon filtration often helps, but the best approach depends on the exact cause. If the taste is persistent or suddenly worse, testing helps confirm what’s driving it.

Question 5

Why does my water taste salty?

Accepted Answer

A salty taste can be caused by elevated sodium, certain minerals, or overall high TDS. It may also be related to local source changes or specific plumbing conditions. Testing helps identify whether the cause is the supply, a treatment device, or household plumbing.

Question 6

What is high TDS and what does it mean?

Accepted Answer

TDS (total dissolved solids) is a measure of dissolved minerals and salts in water. High TDS can affect taste, cause scaling, and impact certain equipment. If taste is the main issue, point-of-use reverse osmosis is a common solution, but testing helps confirm whether TDS is the real driver.

Question 7

Why does hot water smell worse than cold water?

Accepted Answer

Heating can intensify odors, and water heaters can sometimes contribute via reactions with the anode rod or buildup inside the tank. If the smell is only in hot water, the heater is a strong suspect. If it’s in both hot and cold, the source water may be the issue and testing can confirm the cause.

Question 8

My water changed suddenly—taste, color, or smell. What should I do?

Accepted Answer

Sudden changes often indicate a source change, plumbing disturbance, or a new contaminant/condition that needs confirmation. Start by noting whether the change affects hot, cold, or both, and whether neighbors notice it too. A water test helps you avoid guessing and choose the right treatment quickly.

Question 9

Why do I have sand or sediment in my water?

Accepted Answer

Sediment can come from well sources, disturbed plumbing, municipal line work, or seasonal source changes. It can clog aerators, reduce appliance life, and make water look dirty. A sediment filter is often the first step, and testing helps confirm whether additional treatment is needed.

Question 10

What are tannins and why is my water tea-colored?

Accepted Answer

Tannins are natural organic compounds from decaying vegetation, often found in surface-influenced well sources. They can cause tea-colored water, staining, and a noticeable taste. Because tannins behave differently than sediment, treatment is typically specialized and should be matched to test results.
