Bioanalytical Implementation Advisory Group

NWRI facilitates the Bioanalytical Implementation Advisory Group (BIAG), which is working with the California State Water Resources Control Board (Water Board) to develop standard operating procedures (SOP) 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-) and aryl hydrocarbon receptor (AhR) response.

The NWRI-facilitated panel met for the second time, during April, to continue drafting the SOP. A meeting for stakeholder input to the draft SOP will be scheduled sometime in July or August 2019--the meeting date will be posted here as soon as it is set.


The SOP will be released in November 2019.
