Water Monitoring Flashcards
is any process that improves the quality of water to make it appropriate for a specific end-use such as drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.
Water Treatment
making something new from something that has been used before
Recycling
the introduction of any harmful substance into a water environment at a faster rate than it can be cleansed.
Water Pollution
Pollution that comes from a single site.
Point source pollution
