Brown Water - What to Do?

If you see brown water coming from a water pipe, you will likely feel uncertain and wonder about its cause. You might also be concerned about whether this water is harmful to your health.

Possible Causes

Brown water is usually caused by non-toxic deposits of iron or manganese from the pipes. The corrosion of iron in the pipes turns the water orange to brown. If you have pipes with lead content, the water can even turn black. Another possible cause is old or deteriorating pipes that release particles into the water supply.

Health Risks or Harmless?

You should not drink brown water from the tap until you identify its cause. If the discoloration results from washed-out iron or manganese deposits, short-term consumption is generally harmless. However, prolonged consumption of water with high levels of iron or manganese should be avoided.

Be especially cautious with lead pipes. Lead is a toxic heavy metal that can cause poisoning if ingested in large amounts.

Sometimes, brown water may indicate the presence of other harmful substances. For example, a pipe break might allow soil to enter the drinking water supply. Additionally, contaminated surface water can infiltrate the system through broken pipes.

What to Do If Your Tap Water Turns Brown?

• Do not drink the water until you determine its safety.
• Let the water run from multiple taps for a few minutes. If it clears up, turn it off and check again after 30 minutes.
• Contact your water supplier to see if there is a known issue affecting the water quality in your area.
• If you live in an apartment, ask your neighbors whether they are experiencing the same problem. This can help identify whether the issue is localized or widespread.

Analyzing and Testing the Water

A thorough analysis is crucial to ensure safety and identify the cause of discoloration. One simple test you can perform is to smell the water. If it has an earthy or musty odor, it may be due to organic material decomposing in the pipes.

For a precise evaluation, only a professional laboratory test can determine the true cause of the brown water. Such a test can also detect harmful heavy metals or other contaminants. Conducting a drinking water analysis is an important step in ensuring safety and health.
