Unit 1

Question 0

Bioretentiom cells aka rain gardens

Answer 0

Capture filter and store stormwater runoff. stormwater filtered throughout soil. Reduce water pollutants

Question 1

Types of Low Impact Development

Answer 1

Green roofs
Bioretention cells (rain gardens)
Permeable Pavers
Water Harvesting

Question 2

Water Harvesting

Answer 2

Cisterns and rain barrels capture and store runoff. Need something to do with the water

Question 3

Extensive vs. Intensive roof systems

Answer 3

Extensive is lighter while intensive is much heavier with wider variety of plants

Question 4

Endocrine Disrupters

Answer 4

Interrupt the way bodies deal with reproduction and body tissue, causes mutations

Question 5

Estuary

Answer 5

Direct link to the ocean

Question 6

Watershed boundary

Answer 6

Where water flows the opposite ways

Answer 8

Water the surface cannot absorb

Question 9

Ecosystem services

Answer 9

Services provided by the environment

Question 10

Watershed

Answer 10

Area where all water goes to some body of water

Question 11

Impervious surface

Answer 11

Anything water cannot go through, does not allow infiltration

Question 12

Pervious surfaces

Answer 12

Surfaces that allow infiltratoon

Question 13

Combined sewer system

Answer 13

Storm drain and sewer system connected to the same pipe

Question 14

Riparian zone

Answer 14

Ecosystems located along banks of rivers

Question 15

Point source

Answer 15

Specific point that pollution is coming from

Question 16

Non point source

Answer 16

Pollution coming from multiple cumulative inputs

Question 17

Eutrophication

Answer 17

Lots of algae and plants grow because there are so many nutrients. When algae dies it sucks all the oxygen out

Answer 32

Iron

Question 33

Darker soil

Answer 33

More organic matter

Question 34

Steps for water treatment

Answer 34

1- primary treatment 2- Secondary Biological 3- Advanced Treatment 4- Final Treatment

Question 35

Primary Treatment

Answer 35

Removes trash, changes turbidity

Question 36

Secondary Biological

Answer 36

Add microorganisms that eat smaller particles and browns spots decay, ammonia decreases, turbidity goes down a little, COD goes down

Question 37

COD

Answer 37

Chemical oxygen demand

Question 38

advanced treatment

Answer 38

Chemical flockulation suck water away from chemicals and microbes settle at the bottom, ammonia drops, huge drop of tribitiby, lowers COD

Question 39

Flocculation

Answer 39

Colonies of microbes

Question 40

Final treatment

Answer 40

Sand and carbon filter, drop of tribitiby and COD

Question 41

Disinfection

Answer 41

Uv tunnel Chlorine Get rid of microorganisms that get through the original treatment

Question 42

Common pollutants in communities

Answer 42

Surfactants (soap) from carwash Nitrogen(excess fertilizer) from lawns E coli from dog parks

Question 43

2 types of water monitoring

Answer 43

Biological | Chemical

Question 44

Biological testing

Answer 44

BMI looking for creatures , shows health and quality of water

Question 45

Chemical testing

Answer 45

``` ph Tribitiby Temperature Ammonia ( nitrogen) Phosphate ```

Question 46

Biosolids

Answer 46

Pollutant made from the treatment that can be disposed in a land fill, put on farmers fields, or a use as fuel source for generator
