Front 7

Oxygen Sag Curve

Back 7

A sequence of events brought on by bacteria breaking down oxygen demanding wastes that are entering a flowing stream.

Front 8

Lake and Reservoir Recovery

Back 8

Low flow, stratified layers, and little vertical mixing prevent quick recovery of this ecosystem from water pollution.

Front 9

Groundwater Recovery

Back 9

High absorbency of sediments, widening plumes of dispersion, low dissolved oxygen, and less decomposing bacteria prevent quick recovery of this ecosystem from water pollution.

Front 10

River and Stream Recovery

Back 10

Dilution of flowing water and bacterial breakdown enhance the recovery of this ecosystem from moderate water pollution.

Front 11

Cultural eutrophication

Back 11

An acceleration in the input of plant nutrients into a shallow lake, estuary, or slow moving stream brought on by human actions

Front 12

Eutrophication
