摘要：As it crosses a draughty area, especially its lower course, the Ialomi.a river registers low flows in summer, thus, favouring the decrease of the self-filtering process and the maintenance of the polluting substances in quantities which frequently exceed the permissible limit. The pollution is induced by the discharge of the residual waters, insufficiently filtered in the Ialomi.a river, as well as by the polluted water of its tributaries the Prahova and the Sarata. As compared to 1993, when the water was in the category of ¡°degraded¡± quality, in 2000, it can be noticed an improvement of its quality, the 3rd category of quality maintaining only to one or two indicators, the others corresponding to the 1st and 2nd category. The quality of the Ialomi.a can maintain in a superior category only through the efficient filtering of the residual water, which is discharged into this river.
