Questions
Question (1)
In the EU the "Proposed EU minimum quality requirements for water reuse in agricultural irrigation and aquifer recharge" are under discussion and the scientific advice by SCHEER (Scientific Committee on Health, Environmental and Emerging Risks) on JRC related document was published last July 10, 2017 (please see attached document or link to EC web-page http://ec.europa.eu/health/scientific_committees/updates)
In its advice SCHEER suggests to expand JRC respective tables by including contaminants of emerging concern (CECs) and antibiotic resistance (AR) indicator. What is your opinion, should "EU minimum quality requirements for water reuse in agricultural irrigation and aquifer recharge" include CECs and AR?
