Sediments are naturally occurring particles that develop as earth materials are broken down through weathering and erosion. Sediment can consist of sand, rocks, and minerals, or may consist of organic particles of plants and microbes. Sediments may appear in well water as color or cloudiness which may or may not settle on the bottom of containers. This type of sediment is called suspended solids. Additionally, some sediment develops from clear water only after it is exposed to air. This type of sediment is called dissolved solids.
Besides an unappealing look, the sediment in the water can cause wear to plumbing, pumps, and water appliances or even create clogs throughout the water system to reduce the flow of water. Additionally, health risks posed by sediment in drinking water are from pollutants and pathogens that can attach themselves to sediment particles entering your water supply. Potential health contaminants include microbes such as bacteria, virus, and protozoa; from pollutants such as fertilizers and pesticides; and from dissolved metals like mercury, lead, and arsenic.
