Research and Development for Health and Environmental Hazard Assessment. Task Order 1. Development of Data Base Requirements for Human Health Based Water Quality Criteria for Military Recycle/Reuse Applications

摘要

The development of a methodology for derivation of non-potable reuse water quality criteria can be divided into two segments: Determination of the daily allowable dose of a specific contaminant which produces no adverse health effects; and Estimating the concentration of contaminant in the recycled/reused water which would cause the subject to assimilate the daily allowable dose, considering the total exposure received. A first requirement is to assemble an adequate data base defining toxic effects. A second requirement is to develop an adequate data to describe the subjects' exposure to recycle/reuse water. The methodology proposed in this report is intended to serve as a set of guidelines for the development of non-potable water quality criteria.
