A project team performed quarterly water testing and determined that the total dissolved solids (TDS) is above the 500 mg/L threshold. Which of the following steps should the project team take to address this issue?
Correct Answer: A
According to Feature W05: Optimization Drinking Water Quality Management, part 1 of the WELL Core requirements, the project team must test water quarterly in drinking water dispensers and meet the following thresholds: Total Dissolved Solids (TDS) are 500 mg/L or less. If any sample exceeds these thresholds, remediation and re-testing occur within a month1. Therefore, the project team should take the step of remediation and re-testing within one month to address the issue of high TDS levels. References: = Standard | WELL V2
Question 47
Which of the following is an effective measure for a new construction project to reduce noise from nearby traffic?
Correct Answer: D
According to the WELL v2™ feature S02: Maximum Noise Levels, the project must achieve desired ambient noise levels such that HVAC, exterior noise intrusion or other noise sources do not impact occupant health and well-being1. One of the strategies to achieve this is to recommend high sound transmission class (STC) or weighted sound reduction (Rw) performance values for the building facade, windows and any exterior penetrations, as they can provide effective sound insulation and reduce noise transmission from outside sources, such as traffic2. Option A is incorrect, as altering the room geometry and space layouts may not have a significant impact on reducing noise from nearby traffic, unless the rooms are relocated away from the noise source or shielded by other structures. Option B is incorrect, as providing speech reinforcement and public address systems may not reduce noise from nearby traffic, but rather add to the internal noise sources that may affect occupant comfort and communication. Option C is incorrect, as suggesting lightweight floor constructions below noise generating spaces may not reduce noise from nearby traffic, but rather increase the impact noise transmission between floors.

Question 48
A permanently installed an conditioner was used during construction What should be done to this equipment prior to occupancy?
Correct Answer: B
When a permanently installed air conditioner has been used during construction, it is necessary to replace the air filter prior to occupancy. Construction activities can generate a significant amount of dust and debris, which can clog the air filters and compromise the indoor air quality. Replacing the air filter ensures that the air conditioning system can provide clean air and function efficiently, which is essential for maintaining a healthy indoor environment for future occupants.
Question 49
A small percentage of building occupants report chronic thermal discomfort. What strategy should be used to address this problem?
Correct Answer: D
Offering personal heating/cooling devices is the best strategy to address the problem of chronic thermal discomfort among a small percentage of building occupants. This strategy allows occupants to adjust their local thermal environment according to their individual preferences and needs, which can improve their satisfaction and comfort. Personal heating/cooling devices can include fans, heaters, foot warmers, radiant panels, or under-desk air terminals. The other options either do not address the individual differences in thermal comfort or may worsen the problem by creating uniform and inflexible thermal conditions.

Question 50
Which of the following ongoing procedures is required for water dispensers in Feature W06?
Correct Answer: B
According to Feature W06 of WELL v2, water dispensers must be cleaned on a daily basis and their mouthpieces, outlets, protective guards, aerators, and basins must be maintained to ensure drinking water quality and hygiene.
