Conduct regular water quality testing

Rationale: Regularly testing for a comprehensive list of contaminants and publicizing results helps protect occupants from exposure to organisms and chemicals that may be present in drinking water at the point of use, reducing risk of adverse health effects such as lead poisoning, liver and kidney damage, diarrhea, and vomiting.

For the most accurate strategy and documentation requirements, please refer to the digital scorecard made available on the Fitwel Platform.

1. For projects with independent water supplies not connected to the building's main water source (such as water coolers), confirm that potable water will be delivered to the project as outlined under section 4 of the Fitwel v3 Water Quality Testing Protocol.

Option 4 - Water Quality Improvement Protocol (Partial Credit):

If the limits for one or more of the required water quality metrics are not met, the project may achieve partial credit by implementing a treatment protocol that meets the following requirements:

1. Conduct water quality testing that is at least as rigorous as the Fitwel v3 Water Quality Testing Protocol.
2. Conduct water quality testing at the frequency and locations outlined under Section 3 of the v3 Water Quality Testing Protocol.
3. Implement a water quality improvement protocol that is at least as rigorous as the requirements of Section 5 of the Fitwel v3 Water Quality Testing Protocol to improve the water quality metrics that do not meet the following required limits:
   - Arsenic: 0.010 mg/L
   - Cadmium: .003mg/L
   - Copper: 1.3mg/L
   - Total Coliforms: 5.0 percent (no more than 5.0 percent samples total coliform-positive)
   - Lead: 0.015 mg/L
   - Legionella: 0.000 cfu/mL
   - Nitrates: 10 mg/L
   - Turbidity 1.0 NTU
   - Vinyl Chloride: 0.002 mg/L.
4. Implement a water quality improvement protocol that is at least as rigorous as the requirements of Section 5 of the Fitwel v3 Water Quality Testing Protocol to improve the PFAS levels that do not meet the following required limits:

Maximum allowable levels of PFAS:
- PFOA: 4 ppt
- PFOS: 4 ppt
- PFHxS: 10 ppt
- PFNA: 10 ppt
- HFPO-DA: 10 ppt
