Sediment is basically dirt and rocks that settle at the bottom of bodies of water. Though some broaden its definition to be any particulate matter that finds its way into the flow of water.
Sediment usually finds its way into lakes, rivers, and streams by surface runoff. Rain or floods will wash the soil into the nearby water supply. Sediment also naturally erodes from the shore by into the flow of the water’s current. This increases the turbidity in the water, giving it a cloudy, murky consistency.
There’s nothing inherently toxic about sediment, but who wants to drink dirty water? Also, chemicals, organic materials, and other contaminants that are harmful to drink can be carried in by sediment.
Just about all refrigerator water filters remove sediment from drinking water. The better the filter, the more and smaller-sized bits of sediment it can trap.
If a local water supply has a high amount of sediment, it can build up within a water filter very quickly, shortening the filter’s lifespan. A water filter that normally lasts up to 6 months can need changing within 2 to 3 months. If you notice your refrigerator’s “Change Filter” light come on frequently, contact your local water supplier to test for sediment. Often, the installation of a whole house filter is a less expensive alternative to buying extra fridge filters.
