Water testing is performed at a sampling points including both drinking water locations (i.e. sinks, water fountains) and locations where water is meant for human contact (i.e. sinks, showers) using an onsite turbidimeter and collecting water samples to be reviewed in an offsite lab. A complete description of the sampling protocol and the field equipment specifications and methodologies can be viewed in the WELL Performance Verification Guidebook.

Preliminary water quality testing may provide useful feedback for the project team during the integrative design process. However, the official water testing will be performed by the WELL Assessor during the WELL Performance Verification stage of the WELL Certification process. While preliminary testing is not required by projects, the field equipment specifications and methodologies followed by the WELL Assessor can be found in the WELL Performance Verification Guidebook.

Under the Core and Shell program, project teams are responsible for demonstrating that the project is capable of providing tenants with water that meets the WELL Water Quality requirements for drinking fixtures. At least one water dispenser per project is required, even if the tenant buildout has not yet occurred and there are not drinking fixtures installed. WELL Performance Verification testing will occur within any areas built out by the developer.

No, all water, including reclaimed rain water, being used in situations that do not lead to human contact are not required to meet the water quality requirements.

Yes. According to WELL Performance Verification Guidebook, water for human contact is conducted on cold water. However, for mixed water faucets, the hot supply should be turned off. If water temperature conditions cannot be altered, testing is conducted using the available water.

No. If the restrooms are outside the WELL project boundary, the project is not required to meet the water quality requirements at these locations. Performance testing would only occur in fixtures within the project space. However, if the tenant space does not have a drinking fixture, the next closest fixture would be tested (for example: bathroom fixtures outside of the project boundary).
