Water Quality And Pollution

Front 1

Biological Oxygen Law (BOD)

Back 1

The amount of oxygen required for biochemical decomposition processes

Front 2

Environmental Law

Back 2

a set of laws that regulate the interaction between humans and the environment.

Front 3

Contaminants (water)

Back 3

Substances that infect the water until it is unusable

Front 4

Fecal Coliform

Back 4

The most common contaminant- a microorganism that live in the intestines of warm-blooded creatures.

Front 5

Point-Source Pollution

Back 5

Distinct and confined points of drainage (pipes that empty into streams)

Front 6

Non-point Source Pollution

Back 6

Points of pollutants that are not distinct and confined (runoff)

Front 7

Primary Treatment

Back 7

The first step in water treatment. This step includes removing all of the solids such as grit and sludge.

Front 8

Secondary Treatment

Back 8

The second to last section of the water treatment process where the bacteria and other too-small-to-filter-out material are removed.

Front 9

Tertiary Treatment

Back 9

The final section is wastewater treatment- the final polishing of water before it is dumped into the river

Front 10

Effluent Discharge

Back 10

seepage of untreated water in the process of being cleaned or before it even enters the plant

Front 11

Water Renovation and Conversation Cycle

Back 11

the cycle of water in a certain land-
1. return of treated wastewater to irrigation systems
2.seep into the ground
3.reuse of treated water which is pumped out.

Front 12

Wastewater Treatment (sewage treatment)

Back 12

The process of cleaning degraded industrial water into drinkable water.

Front 13

Runoff

Back 13

the excess of water that "runs off" and collects material on the ground as it flows

Front 14

Watershed

Back 14

the place that all runoff water collects

Front 15

Eutriphication

Back 15

The process by which a body of water develops a high concentration of nutrients (Nitrogen and phosphorous)

Front 16

Dead Zone(s)

Back 16

where the oxygen levels are not suitble for life

Front 17

pH

Back 17

a measurement of acidity

Front 18

Dissolved Oxygen

Back 18

the amount of oxygen in agiven medium

Front 19

Chlorination

Back 19

a method of water treatment where chlorine is added to kill any bacteria

Front 20

Aquifer

Back 20

a layer underground of water-permable rocks where water is pumped out of

Front 21

Hypoxia

Back 21

the condition where a body of water is severly deprived of oxygen

Front 22

Methane Gas

Back 22

a widly distributed gas in nature

Front 23

Activated Sludge

Back 23

using air to treat water

Front 24

Leachate

Back 24

water that has leached some pollutants from a solid
