A watershed derived from a disused gravel-quarry has been studied for the relocation of the catchment area of Turin surface water treatment plants. The improvement of river water quality as a consequence of short-term storage has been investigated, focusing the attention on three problem organisms, namely the parasitic protozoans Giardia spp. and Cryptosporidium spp. and the free-living Nematodes, which could be considered indicators of healthy compliance and product agreeability respectively.
