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.

Requirements

Demonstrate compliance with one of the options below:

Option 1 - Water Quality Testing (Full Credit):

Demonstrate compliance with all the following requirements:

1. Conduct water quality testing that is at least as rigorous as the Fitwel Water Quality Testing Requirements.The Fitwel Water Quality Testing Requirements can be found here.
2. Conduct water quality testing at the frequency and locations outlined under Section 3 of the v3 Water Quality Testing Protocol.
3. Confirm water testing results meet all of the following maximum contaminant level 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. Confirm that PFAs are limited in the water supply through one of the following:
   • test for PFAs and confirm that results meet the below maximum levels
   • demonstrate that the municipal water supply monitors PFAs levels and that detected levels are below the maximum.Maximum allowable levels of PFAs:
     • PFOA: 4 ppt
     • PFOS: 4 ppt
     • PFHxS: 10 ppt
     • PFNA: 10 ppt
     • HFPO-DA: 10 ppt

Option 2 - Non-Potable Water Source (Full Credit):

Demonstrate compliance with the following requirement:

1. For buildings and spaces in which the municipal water supply is not potable and where water is treated by the building before consumption, confirm that the water meets the maximum contaminant level limits from one of the following standards:
   • the United States Environmental Protection Agency National Primary Drinking Water Regulations (found at fitwel.org/fitwel-standards)
   • the World Health Organization, Guidelines for Drinking-Water Quality, Fourth Edition (found at fitwel.org/fitwel-standards)
   • the local official drinking water quality standard.

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.The Fitwel Water Quality Testing Requirements can be found here.
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
