Water Concept Flashcards
3 types of water
Potable
Non potable
Process water
4 routes of exposure to water
Ingestion
Inhalation
Skin absorption
Injection
Water fit for consumption
Potable water
Water not fit for consumption
Non potable water
Water used for cooling towers, boilers and industrial processes, can be either potable or non potable.
Process Water
Feature 30: Fundamental Water Quality is a pre condition for …
all 3 project types
Feature 30: Fundamental Water Quality. Part 1: Sediment requires water sample to have?
Turbidity level of less than 1.0 nephelometric turbidity unit NTU
Water clarity is measured in terms of?
Turbidity
Amount of cloudiness in a liquid
Turbidity
Higher turbidity means?
Greater sedimentation. This is bad.
Unit of measure for turbidity
NTU
Feature 30: Fundamental Water Quality requires public drinking water be?
Maximum 5.0 NTU
Feature 30: Fundamental Water Quality requires water utilities be maintained at what level?
0.1 NTU
Why is low turbidity important?
Low turbidity - important so UV light treatment can be used. If high, sediments block UV rays
Feature 30: Fundamental Water Quality. Part 2: Microorganisms requires water be?
Requires that water must be tested to ensure no coliforms
Microorganisms including E.Coli
Coliforms
Increased coliforms means?
Presence of other pathogens
Infectious such as bacteria, virus, fungu
Pathogens
Test the effectiveness of a project’s water filtration
Total Coliform Teset
Feature 31: Inorganic Contaminants precondition for all?
3 project types
Element or compound found in water, such as from mining etc
Inorganic contaminant
Feature 31: Inorganic Contaminants. Part 1: Dissolved Metals addresses what?
Addresses 6 major contaminants such as
ALMANC
arsenic lead mercury antimony nickel copper
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
2 types of water filtration
