All of the river and stream water samples sent in by the general public will be analysed at the University of Warwick to see what chemicals they have in them and what levels of antimicrobial resistant bacteria they have.

Pilot Study

Following a successful pilot study based in Warwickshire, looking at the numbers of coliform bacteria, E.coli bacteria and antibiotic resistant bacteria in the river water, we are now sending out sample kits. Click on the map to see where samples have been collected so far. Results for each sample will be added when available.

Where have you been sampling?


All water samples will be analysed by a Triple Quad Mass Spectrometer to determine levels of antibiotics as well as other pharmaceuticals and agrochemicals.

A list of the chemicals to be analysed. Antibiotics amoxicillin, ciprofloxacin, sulfamethoxazole, trimethoprim, erythromycin, oxacillin, tetracycline. Pesticide - fipronil sulfone and also caffeine.


All water samples will be analysed to determine the levels of antimicrobial resistance by both culture and DNA based methods.
