EstuariesEstuary: is a body of water, partially enclosed by land, where fresh water from a river mixes with salt water from the ocean.
Water in Estuaries is Brackish. Brackish means partly fresh and partly salty.

Filtering System
• Estuaries clean our rivers by removing…..
Sediment and Pollutant.
This makes me think of…______
Sediments• Sediment – Soil particles and chemicals carried
by the river• Carrying of soil Muddy estuaries– Soil can smother fish eggs, aquatic insects, and
plants with mud.
• Erosion of land Chemical deposits– Chemicals can kill life
• Some estuaries are actually salt marshes.– These plants and
mud take up some of the sediments and pollutants!

Pollutants
• Pollutants: Pesticides, sewage and industrial waste
• Estuaries are a type of environmental filter.
• Plants and animals in estuaries filter pollutants out of the water.
Pollutants
• Ex: Salt Marsh Plants trap some of the chemicals and pathogens carried by rivers and move them into soils where they can be neutralized.
• Ex: Oysters filter impurities out of the water as they eat, collecting contaminants in their bodies. One oyster can filter 25 gallons of water per day
• Too many toxins can accumulate in estuaries causing many environmental and health problems
