To limit the presence of agricultural contaminants in drinking water.
The thresholds that we provide for nitrate and nitrogen can be considered interchangeable, and because labs may report this differently, we provide both as a reference.
As a landlord of a Core and Shell project, where do I need to meet the water quality requirements? Do I need to set tenant design guideline requiring that the WELL Water Quality requirements be met within tenant spaces?
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.
My project uses reclaimed rainwater, however it is used only for urinals, toilets, dishwasher, and irrigation. Is this water required to meet any of the WELL Water Quality requirements?
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.
For the Water concept, are the WELL requirements for drinking water testing applicable only to cold water?
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.
I am a tenant in the building and the restrooms are operated and maintained by the building landlord, hence are outside our tenant space. In this situation, are the WELL water quality requirements still applicable in these bathrooms?
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).
My project has an irrigation system and a separate portable water system. Are the WELL water quality requirements applicable to both systems?
No. The project's irrigation system would not be required to meet the feature requirements since the irrigation water is not intended for human consumption or human contact. However, the potable water system intended for human consumption must meet the limits defined within this feature.
Where is water sample testing performed and what equipment is used during WELL Performance Verification?
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.
Is my project required to conduct preliminary testing of water quality to confirm that the WELL water quality requirements are being met?
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.
