Information for Various Types of Non-ATSDR Screening Levels
There are various types of non-ATSDR screening levels; this table lists some. Note that ATSDR does not endorse the use of any non-ATSDR screening level, but this list includes sources suggested by health assessors for various types of non-ATSDR screening levels. Many available non-ATSDR screening levels are based on health effects observed in scientific studies, but others are not completely health-based. Health assessors should choose non-ATSDR screening levels that are most protective of the potentially exposed population, and are most akin to ATSDR’s health-based CVs. Before using non-ATSDR screening levels in your analysis, ensure you understand how the non-ATSDR screening levels were derived and discuss their possible use with the Associate Director for Science (ADS) group.

 Soil and groundwater are each categorized into three classes. Standards are listed in Table 1 of Subpart B of the PDF. While the criteria to determine which standard to use are explained in Link 1, Link 2 (page 3) is easier to read.  |
