Why Is There Black Debris In My Water?

Posted by Ryan Forest

Water is an essential part of our daily life, so we want it as clean as possible. But what does it mean when you start seeing black debris in your water? 

Reasons for Debris in Your Water

Naturally, clear and colorless water is always most desirable. But there are times when that isn’t the case.


Your local government should be enforcing the traces of manganese and iron in the water. But there are times when there could be high traces of these minerals in your water, which could cause your water to look rather unpleasant. This is harmless, but it could stain your faucet and clean dishes.


Are you using water from a private well? If so, sand and silt can easily get into your water system. Again, this is harmless, but the extra particles could cause damage to your water pump, dishwasher, or even your washing machine. To prevent this, run the water until it is clear of the particles or use a screen to catch the sand and silt.


Rust particles are usually orange or brown, but there are instances where they can appear black. It is not uncommon for rust to appear in your water from your plumbing pipes. You can usually tell by their hard texture and irregular shape and size. This could be a sign that you have a leak in your pipes since they are rusting, so call your plumber in Mesa to inspect the situation.

Granular Activated Carbon (GAC)

Are you using a water filter system? They often use granular activated carbon to filter the water. This can sometimes leave odd shaped and hard particles in your water, usually resembling coffee grounds. If this is the case, inspect your water system and replace the filter cartridge.


If the flex hose leading to your water supply is disintegrating, it could leave oily and smudgy debris in your water. Sometimes when adding chlorine or chloramine to the water supply to disinfectant, it can corrode the rubber, causing it to disintegrate. In these cases, you will need your hose replaced.  However, thanks to new technology, the newer hoses come with a water disinfection-resistant lining!
