3 types of water

Potable
Non potable
Process water

2

4 routes of exposure to water

Ingestion
Inhalation
Skin absorption
Injection

3

Water fit for consumption

Potable water

4

Water not fit for consumption

Non potable water

5

Water used for cooling towers, boilers and industrial processes, can be either potable or non potable.

Process Water

6

Feature 30: Fundamental Water Quality is a pre condition for ...

all 3 project types

7

Feature 30: Fundamental Water Quality. Part 1: Sediment requires water sample to have?

Turbidity level of less than 1.0 nephelometric turbidity unit NTU

8

Water clarity is measured in terms of?

Turbidity

9

Amount of cloudiness in a liquid

Turbidity

10

Higher turbidity means?

Greater sedimentation. This is bad.

11

Unit of measure for turbidity

NTU

12

Feature 30: Fundamental Water Quality requires public drinking water be?

Maximum 5.0 NTU

13

Feature 30: Fundamental Water Quality requires water utilities be maintained at what level?

0.1 NTU

14

Why is low turbidity important?

Low turbidity - important so UV light treatment can be used. If high, sediments block UV rays

15

Feature 30: Fundamental Water Quality. Part 2: Microorganisms requires water be?

Requires that water must be tested to ensure no coliforms

16

Microorganisms including E.Coli

Coliforms

17

Increased coliforms means?

Presence of other pathogens

18

Infectious such as bacteria, virus, fungu

Pathogens

19

Test the effectiveness of a project’s water filtration

Total Coliform Teset

20

Feature 31: Inorganic Contaminants precondition for all?

3 project types

21

Element or compound found in water, such as from mining etc

Inorganic contaminant

22

Feature 31: Inorganic Contaminants. Part 1: Dissolved Metals addresses what?

Addresses 6 major contaminants such as
ALMANC
arsenic lead mercury antimony nickel copper

23

ALMANC levels?

ALMANC .01
Arsenic - less than 0.01
Lead - less than 0.01 mg/L
Mercury - less than 0.002
Antimony - less than 0.006
Nickel - less than 0.012
Copper - less than 1.0

24

2 types of water filtration

Reverse Osmosis

Kinetic degradation fluxion KDF

25

Filtration type that uses semi permeable membrane to filter water; very fine filter that only allows water molecules to pass through

Reverse Osmosis

26

Pros/Cons of Reverse Osmosis

Effective at removing contaminants, but wastes 50 to 80% of incoming water supply

Some circulate back to building for non potable purposes

27

Filtration system that contains flakes or granules of copper and zinc

Kinetic degradation fluxion KDF

28

Kinetic degradation fluxion KDF pros/cons

Effective up to 98% in removing inorganic contaminants

o Not effective at removing chemicals or parasites

29

Human made compound from industrial activities

Organic Contaminants

30

Feature 32: Organic Contaminants lists 8 key pollutants. Which are?

What the required level for Styrene?

BTTSPVEX
