W03 Basic Water Management Part 1 Monitor Chemical and biological water quality
option 1 drinking water quality report - Answers -A.The following water parameters are
sampled at intervals no less that once per year
turbidity
PH
residual (free) chlorine
total coliforms (only if chlorine is ok)
any other water parameter found at 80% or above its threshold found in W02. testing
occurs only at location where parameters were found and tested there until below 80%
of its threshold
B.The number and location of sampling points for ongoing monitoring complies with the
requirements outlined in the performance verification guidebook
C. The water quality results are submitted annually through well digital platform
How much of the human body is made of water? - Answers -2/3
it is a major component of cells and the dominant component of fluid between cells
Water standard include features that address - Answers -availability and contaminant
thresholds of water
management of water to avoid damage to building materials and environmental
conditions
The well water concept covers aspects of - Answers -quality
distribution
control
in a building
One contributing factor that makes people inadequately hydrated - Answers -real or
perceived quality of drinking water
people mistrust the safety of their water
this leads to lower intake of water and higher intake of sugary beverages
What does water do for the body - Answers -the medium for the transport of nutrients
and waste in the body and helps regulate the internal body temperature
,Guidelines for water intake - Answers -49-125 oz depending on age, sex, and
pregnancy status
One of the 10 greatest public health achievements of the 20th century according to the

exposure can impair neurodevelopment in children
Risk of using chemicals to disinfect drinking water - Answers -these chemicals can
combine with natural organic matter generate byproducts sometimes correlated with
reproductive disease and cancer
-trihalomethanes
-haloacetic acids
How to design water treatment systems that address the necessary contaminants for an
area - Answers -identifying which contaminants are a concern on the local scale.
bc of wide variety in water across the globe
this removes undue complexity and wastewater
Besides consumption where can water be used in a building - Answers -heating and
cooling systems
irrigation
pools
baths
general appliances
Prime conditions for mold growth - Answers -if any building material gets wet from any
source unintentionally
what mitigates the risk of water - Answers -careful building design with responsive
operations which allows for easy and meaningful means of inspection
Well water concept aim overall - Answers -increase the rate of adequate hydration in
building users , reduce health risks due to contaminated water and excessive moisture
w/in buildings
, provide adequate sanitation through better infrastructure design and operations coupled
with awareness and maintenance of water quality
W01 Water Quality Indicators Intent - Answers -Precondition
Verify the quality of water for human contact through easy to test parameters
W01 Water quality indicators Summary - Answers -This well feature requires the
provision of water that meets thresholds for turbidity and coliforms for all water likely to
come in contact with building occupants and verifies performance testing using on site
tests
W01 Water quality indicators issue - Answers -safety with water consumption
Two commonly used parameters used to assess the effectiveness of extensive water
treatment systems - Answers -Total coliforms and turbidity
these are easy to test measurements for possible presence of other more concerning
contaminants
these are known as indicators
Coliform - Answers -naturally occurring bacteria generally harmless but some are
associated with fecal contaminents
Turbidity - Answers -a measure of water cloudiness
this can relate to the availability of food and shelter for microbes
(shows issue with water treatments process as well as aesthetic concern)
W01 Water quality indicators solutions - Answers -water filtration can reduce turbidity
and depending on the type of device may also trap bacteria and other contaminants
if the water has low turbidity disinfection at the point of use with UV light may be
effective at killing coliforms and pathogenic microbes
W01 Water quality indictors Part 1 - Answers -Verify water quality indicators
Water delivered to the project and intended for human contact :
A. turbidity is less than or equal to 1.0 NTU or FNU
B. Coliforms are not detected in any 100 ML sample
W02 Drinking Water Quality Intent - Answers -Precondition
Provide access to drinking water that complies with health based limits on chemical
composition
