Bioanalytical Implementation Advisory Group

NWRI facilitates the Bioanalytical Implementation Advisory Group (BIAG), which is working with staff from the California State Water Resources Control Board to develop standard operating procedures for two types of bioanalytical assays.


The revised Recycled Water Policy, which became effective on April 8, 2019, requires recycled water producers to evaluate bioanalytical assay monitoring results for estrogen receptor alpha (ER-a ) and aryl hydrocarbon receptor (AhR) response.

NWRI facilitated workshops in January and September 2019 to gather stakeholder input and questions for the BIAG.


The guidance document will be released by WateReuse California in early 2020. 

For questions about the BIAG, contact Suzanne Sharkey.
