Tier 3 pesticides are the least hazardous pesticides according to the City of San Francisco Pesticide Hazard Screening Protocol, which is one of the reference standards used by WELL v2 to evaluate pesticide safety. WELL v2 requires projects to use outdoor pesticides with a Hazard Tier ranking of 3, except in cases of emergency, and to implement an Integrated Pest Management plan to minimize pesticide use.

According to Feature W05: Optimization Drinking Water Quality Management, part 1 of the WELL Core requirements, the project team must test water quarterly in drinking water dispensers and meet the following thresholds: Total Dissolved Solids (TDS) are 500 mg/L or less. If any sample exceeds these thresholds, remediation and re-testing occur within a month1. Therefore, the project team should take the step of remediation and re-testing within one month to address the issue of high TDS levels.

Exposure to poor indoor air quality can lead to immediate discomforts such as headaches, dry throat, eye irritation, and runny nose. These symptoms are among the short-term effects that indicate the need for improved air quality measures within indoor environments.

Feature A11: Source Separation mandates that spaces with high pollution potential, like copy rooms, have their air exhausted directly outside to prevent indoor air quality deterioration. Copy rooms often house equipment like photocopiers and printers, which can emit volatile organic compounds (VOCs), particulate matter, and ozone, contributing to indoor air pollution. By ensuring that air from these spaces is expelled rather than recirculated, the strategy minimizes the spread of pollutants throughout the building, safeguarding occupant health and aligning with the WELL Standard's emphasis on optimal indoor air quality.
