Purpose of the White Paper Purpose of the White Paper • • The information contained in this document will serve as the The information contained in this document will serve as the foundation for decision- -making for the subsequent making for the subsequent foundation for decision development of AWQC for CECs when the need arises. development of AWQC for CECs when the need arises. • • This white paper and the recommendations it contains does This white paper and the recommendations it contains does not supersede the Guidelines Guidelines for Deriving Numerical for Deriving Numerical not supersede the National Water Quality Criteria for the Protection of Aquatic National Water Quality Criteria for the Protection of Aquatic Organisms and Their Uses or “ “Guidelines Guidelines” ” (Stephan, C.E., (Stephan, C.E., Organisms and Their Uses or D.I.

Brungs, • • Document intended to serve as supplemental information to Document intended to serve as supplemental information to guide the problem formulation and effects characterization guide the problem formulation and effects characterization of the ecological risk assessment paradigm as applied to of the ecological risk assessment paradigm as applied to ambient water quality criteria development for aquatic life. ambient water quality criteria development for aquatic life.

Focus of the White Paper Focus of the White Paper • • This white paper discusses some of the major technical This white paper discusses some of the major technical issues that challenge development of AWQC for issues that challenge development of AWQC for contaminants of emerging concern (CECs) specific to the contaminants of emerging concern (CECs) specific to the use of the current Guidelines Guidelines use of the current • • The paper also presents specific technical recommendations The paper also presents specific technical recommendations reflecting best available science that address those issues reflecting best available science that address those issues and may allow progress with respect to derivation of AWQC and may allow progress with respect to derivation of AWQC for CECs with same technical rigor currently achieved using for CECs with same technical rigor currently achieved using the Guidelines. Guidelines. the

Additional Considerations Additional Considerations • • The workgroup realizes that there are other concerns The workgroup realizes that there are other concerns inherent to the criteria derivation process that have been inherent to the criteria derivation process that have been identified, but these concerns are not specific to CECs, nor identified, but these concerns are not specific to CECs, nor do the recommendations presented here preclude other do the recommendations presented here preclude other efforts to address these issues. efforts to address these issues. • • Some of these issues are currently being addressed under Some of these issues are currently being addressed under separate criteria derivation or guidelines revisions efforts; separate criteria derivation or guidelines revisions efforts; • • Other issues may require additional information so that Other issues may require additional information so that scientifically defensible methods can be developed to scientifically defensible methods can be developed to address them. address them.
