Poor water clarity is a result of extremely high nutrient and sediment levels derived from sewage and urban runoff.

The experiment showed that the plants with the greater sediment levels had more plant cover, with higher plants and a greater bulk density.

Drinking water is removed above the sediment level so there is no hazard.

Heavy rain can result in high sediment levels in rivers and land runoff, and can contain bacterial contamination from livestock.

Where aerobic digestion can result in the control or reduction of organic sediment levels, anaerobic digestion almost always allows organic sediments levels to increase.

The above-average values persisted for roughly a year before the streams returned to pre-cyclone sediment levels.

Recently, federal stimulus funds were awarded for studying sediment levels on coastal rivers.

Any changes to recipes/ingredients, etc., during the year, which would significantly affect sediment levels, must be notified to us and the allowance adjusted accordingly.

Human activities that disturb land, such as construction, mining and agriculture, can lead to high sediment levels entering water bodies during rain storms due to storm water runoff.

"There are terrible dissolved oxygen levels, terrible sediment levels."
