Relationship between precipitation, flow, water temperature and soil use with adenovirus contamination in surface water resources 100 characteristics such as: accessibility to collection sites, municipal boundaries, perception of effluents entering the river and water collection points for supply, with a distance of 8 to 10 km between the selected points. Points 1, 2, 3, 4, 7, 9 and 10 were classified as rural, points 5, 6 and 8 classified as urban. Figure 1. Location of sampling points in the Basin 2.2 Sampling Four campaigns were carried out for samplings of AdVs suspended on the water’s blade of river (06/27/2016, 09/24/2016, 12/03/2016 and 03/18/2017).
