Is Rusty Water Harmful?

Reddish-brown water, often with rust specks, is often caused by oxidized iron in corroded pipes or water systems. It is common in older water systems, and can also be a temporary problem when a large amount of water runs through a system.

  1. Health

    • Although it can be unappetizing, rusty water is not a sign of harmful bacteria, and is not a health concern. A sudden burst of rusty water could mean there is a change in flow in the water system, such as when fire hydrants are flushed. In those cases, water officials could ask community members not to drink the water until the situation is resolved.

    Laundry

    • Rusty water can cause stains in laundry, and if water is temporarily brown, it is best not to do laundry until the problem resolves. Using chlorine bleach in rusty water could cause a permanent stain.

    Causes

    • Rusty water can be caused by either pipes in a home or iron in an entire water system. If the rusty-colored water is only coming from certain faucets in the home, the problem is likely in pipes in the home. Rusty water throughout a home is a sign of problems in the water system.
