Week 3: Water Flashcards
What does the WELL Water concept aim to address?
WATER > General
The WELL Water concept aims to increase the rate of adequate hydration in building users, reduce health risks due to contaminated water and excessive moisture within buildings, and provide adequate sanitation through better infrastructure design and operations coupled with awareness and maintenance of water quality.

What role does water play in the human body?
WATER > General
Water is a major component of cells and the dominant component of fluid between the cells. It serves as the medium for nutrient and waste transport throughout the body and helps to regulate internal body temperature.

What are the recommended daily water intake values for adults?
WATER > General
Depending on age, sex, and pregnancy status, guidelines recommend daily water intake values between 49-125 oz for adults, which include water in foods as well as direct consumption.

What is one contributing factor to inadequate hydration?
WATER > General
One contributing factor to inadequate hydration is the real or perceived quality of drinking water, as people who mistrust the safety of their water can be more likely to have lower intake of water and higher intake of sugar-sweetened beverages.

What are some risks associated with water contamination?
WATER > General
Risks associated with water contamination include impairments to oxygen transport in infants from high nitrate levels, neurodevelopmental impairments in children from lead exposure, and potential correlations with reproductive disease and cancer from disinfection byproducts like trihalomethanes (THMs) and haloacetic acids (HAAs).

What is emphasized as a key aspect in building design to mitigate risks associated with water?
WATER > General
Careful building design that integrates responsive operations and allows for easy and meaningful means of inspection is emphasized to mitigate risks associated with water, such as mold growth from water contacting building materials not intended to get wet.

What parameters are used to verify the quality of water for human contact?
W01 WATER QUALITY INDICATORS | Precondition
The quality of water for human contact is verified through on-site tests, focusing on thresholds for turbidity and coliforms.
Coliform bacteria are indicators of possible fecal contamination, while turbidity measures water cloudiness, which can affect microbial growth and the efficacy of water treatment technologies.

What solutions are recommended to address water quality concerns related to turbidity and coliforms?
W01 WATER QUALITY INDICATORS | Precondition
Water filtration can reduce turbidity and may also trap bacteria and contaminants. Additionally, if water has low turbidity, disinfection at the point of use with ultraviolet (UV) light may effectively kill coliforms and pathogenic microbes.

What thresholds must water meet for human contact?
Part 1 of W01 | Verify Water Quality Indicators
W01 WATER QUALITY INDICATORS | Precondition
Water intended for human contact must have turbidity less than or equal to 1.0 NTU, FTU, or FNU and coliforms not detected in any 100 ml sample.

Are there any exceptions for multifamily residential projects regarding water testing?
Part 1 of W01 | Verify Water Quality Indicators
W01 WATER QUALITY INDICATORS | Precondition
Yes, multifamily residential projects may achieve WELL Certification at the Bronze or Silver level without testing in dwelling units, but they cannot achieve Gold or Platinum without testing in dwelling units.
