Health Hazard Assessments are included in this methodology. Health Hazard Assessments identify health hazards, evaluate proposed hazardous chemicals, materials, and processes, and propose protective measures to reduce the associated risk. PMs should include the requirement to conduct Health Hazard Assessments in their contracts.

[13] Many solvents can lead to a sudden loss of consciousness if inhaled in large amounts. The aggregate of evidence is overwhelming that the well water is positively associated with some adverse health effects. However, it should be pointed out that by no means do our findings confirm any cause and effect relationship between the contaminants in the wells and adverse health effects. Our study was an observational study. "Acute risk" means the potential for a contaminant or disinfectant residual to cause acute health effects, i.e., death, damage or illness, as a result of a single period of exposure of a duration measured in seconds, minutes, hours, or days. §64400.10.
