Monitoring Framework Development of a monitoring program must take into account what type of water is being monitored. This should be transposed against the different drivers for that monitoring.

Use of Surrogates in Monitoring Prioritize those that are persistent and follow the waste stream. –Low degrees of removability/treatability: no sorption, no biodegradation. This suite of materials might include sucrolose, C4 C6 perfluorosulfonate, nicotine, caffeine, coprostanol. Compounds would be expected to be found in the different types of water depending on solubility, fecal association (hydrophobicity), etc. Presences or absences could be a good diagnostic. –What would make it past sludge treatment? –What is removed by AOP?

Monitoring methods

Development of Priority Monitoring Each grid locations has a different set of questions and criteria around the toxicity information, occurrence or persistence info, and monitoring method availability. Monitoring of effluent of any given type of water needs to be performed based on what the considerations are for the receiving waters. The next step for the matrix would be further-defined questions for each box in the matrix. For example, what are the relevant human health concerns associated with discharge groundwater?
