Q

Eutrophication

A

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

18
Q

Hypoxia

A

Not enough oxygen to support life

19
Q

Dead zone c

A

Constantly hypoxic areas , long term

20
Q

Salinization

A

Groundwater turning salty from ocean water seeping in

21
Q

Algae

A

Forms because or large amounts of nitrogen and phosphorous in water

22
Q

Particle sizes of soil

A

Biggest: sand
Medium: silt
Smallest: Clay

23
Q

Infiltration capacity

A

Rate of water and oxygen pass through soil

24
Q

Compacted soil

A

Weighed down, clogged pores

25
Q

Biggest problems in chesepeak

A

Nitrogen, phosphate, and sediment

26
Q

Soil horizons

A

Different layers

O,A,E, B,C,R

27
Q

A

A

Topsoil

28
Q

E

A

Drained out soil

29
Q

B

A

Sticky, mostly clay soil

30
Q

C

A

Less clay in soil

31
Q

R

A

Rock

32
Q

What makes soil red?

A

Iron

33
Q

Darker soil

A

More organic matter

34
Q

Steps for water treatment

A

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

35
Q

Primary Treatment

A

Removes trash, changes turbidity

36
Q

Secondary Biological

A

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

37
Q

COD

A

Chemical oxygen demand

38
Q

advanced treatment

A

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

39
Q

Flocculation

A

Colonies of microbes

40
Q

Final treatment

A

Sand and carbon filter, drop of tribitiby and COD

41
Q

Disinfection

A

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

42
Q

Common pollutants in communities

A

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

43
Q

2 types of water monitoring

A

Biological

Chemical

44
Q

Biological testing

A

BMI looking for creatures , shows health and quality of water

45
Q

Chemical testing

A
ph
Tribitiby
Temperature
Ammonia ( nitrogen) 
Phosphate
46
Q

Biosolids

A

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
