Sediment in drinking water

Sand, rust and grit. An aesthetic and clogging issue rather than a health one.

This page can’t tell you what’s in your tap water.

Only a test of water from your own tap can. Public-system results describe the system, not your home.

Reference values

No numeric reference held.

Each value says what kind of reference it is, and they mean different things. A lower or missing number never means water is safe.

No numeric reference held

WaterDecoder doesn’t hold a verified reference value for sediment in drinking water. That doesn’t mean any level is safe. It means we haven’t verified one to show you.

Is it in my water?

Only a test of your own tap can tell.

Choose what you have. We’ll show what it can and can’t tell you.

If you haven’t tested

Nobody can tell without a measurement, including us.

Testing

How to test your tap water for sediment

Utilities sample to check system compliance. Your result reflects your own pipes and fixtures.

01Use a certified labA state-certified lab, or a kit that sends samples to one.
02Follow the sampling stepsHow and when you collect the water changes the result.
03Check the reportIt should state units and the detection limit.

How to reduce sediment in water

Approaches that can lower sediment at the tap.

How to reduce sedimentA sediment pre-filter rated by micron size traps it: coarser for visible grit, finer for fine silt. It’s usually the first stage ahead of a carbon or RO filter, protecting and extending the life of the finer media behind it.

Whole-house systems and point-of-use filters treat different water. A whole-house system treats water where it enters the home; a point-of-use filter treats the tap it’s installed on. Check which one a claim is for.

Evidence

What the evidence means

We keep evidence types apart. A result for one configuration never stands in for another, and we never average across types.
