Abstract
Water resources are of use for all categories in conditions where pollution indicators and toxins are
within the approved national and international organisations that enable use as drinking water,
agricultural water, or water discharged from economic activities, mainly industrial ones. Other studies,
or those taken from the monitoring system at different levels, show that waters of rivers, lakes, seas and
reservoirs in the country contain contaminating substances in values that damage the aquatic
environment and reduce use values. From analyses performed in drainage hydrovore ‘Tale’, in the city of
Lezha, at three monitoring points: before hydrovore, after hydrovore, and before the sea release for pH
inductivity indicators, chlorides, sulphates, phosphates, nitrite, nitrates, ammonia, turbulence, dissolved
oxygen, temperature, COD (chemical need for oxygen), coliform, Cu, Pb, Zn, and Cr.
It turns out that at the points that we analysed, the parameter content is above the limits allowed for
substances such as phosphates and heavy metals. At all three points, they have emerged above the
permitted value, as well as high organic loads of BOD and COD. Like physico-chemical parameters and
microbiological parameters (e-coli, coliform) indicate considerable faecal pollution. The study performed
shows us the impact of urban and agricultural pollution as well as marine salts on water quality.
