Question #: 40
Topic #: 6
[All WELL-AP Questions]

Which of the following performance testing results is compliant with the requirements of the WELL Building Standard's Water concept?

Show Suggested Answer Hide Answer
Suggested Answer: D

The WELL Building Standard's Water concept sets strict limits for contaminants, including heavy metals like cadmium, in drinking water to protect human health. A performance testing result showing cadmium levels at or below 0.01 mg/L is considered safe and compliant with drinking water quality standards, reflecting the Standard's commitment to providing clean and safe water for consumption.

Haha, I bet the WELL Building folks would give a big thumbs down to any of those other options. Gotta keep it clean with that Cadmium, baby!

D is the way to go, folks. Keeping those water contaminants low is key for a WELL-certified building.

Hmm, I'll go with D. Wouldn't want to be drinking water with too much copper, lead, or chromium. Cadmium's the way to go!

Option D is the winner! Gotta keep those heavy metals in check for a healthy building, am I right?

D definitely looks like the right choice here. The other options are way too high for the water quality standards.

I think the correct answer is D. Cadmium is equal to 0.01 mg/L, which seems to be the only one that meets the WELL Building Standard's requirements.

I believe copper is usually acceptable at higher levels, but I can't remember if 5 mg/L is compliant or not.

I’m a bit confused about chromium and cadmium; I can't recall which one has a stricter limit according to the WELL standards.

I feel like we practiced a question similar to this in class, and I think lead was one of the metals that had a very low threshold.

This looks straightforward. I just need to match the metal concentrations to the WELL standard's limits. Shouldn't be too hard if I can remember the right values.

I'm a bit confused on this one. I know the WELL standard covers water quality, but I'm not sure of the exact thresholds for each metal. Guess I'll have to do some research.

Okay, I think I know the answer here. The WELL Building Standard has specific limits for heavy metals in water, so I'll need to compare the values given to those limits.

Hmm, this seems like a tricky one. I'll need to carefully review the WELL Building Standard's requirements for water quality.
