Effluent
wastewater that is cleaned and released into the environment (rivers/streams).
Energy resources

Floc

Groundwater
Water that is stored beneath surface - in the holes in rocks
Lode

Nuclear power
power produced by the splitting of atoms to produces steam to turn turbines to produce electricity
Overburden

Thermal pollution
The harmful release of heated liquid into a body of water or heat released into the air as a waste product of a business.
