Romanian Surface Water Quality: Tarnava Mare River Between Medias and Copsa Mica Case Study

Abstract

A set of 500 water samples collected from various sites of Tarnava Mare River, between Medias and Copsa Mica were analyzed, during three years (2010)(2011)(2012). The physicochemical parameters like: temperature, pH, electrical conductivity (EC), total dissolved solids (TDS), salinity, calcium (Ca . It was found that the water samples collected from various sites were contaminated with chloride, nitrate and nitrite. Since health, plant and animal life can be affected, the system needs to be monitored and improved in terms of water quality, based on appropriate measures and rehabilitation options, to make it good for uses. In particular, the industrial units along the river need to improve their technology and implement cleaner production methods.

Water quality analysis and model simulation for the second largest polluted lake in Egypt

“…The spatial variation of NO3-N showed the minimum and maximum values of 0.6±0.1 mg/L at Z3 and 1.9±0.5 mg/L at Z6 (p < 0.01), respectively (Figure 3d). According to Ayers and Westcot [9], the degree of restriction for NO3-N in Burullus Lake on reuse was "None". However, the increase in NO3-N concentration over 0.3 mg/L suggests the occurrence of eutrophication.…”

“…The increased concentration of PO4-P at Z2 (2.2±0.4 mg/L), Z4 (3.3±0.8 mg/L), and Z6 (4.8±0.2 mg/L) could result from the discharges of drains [7][8][9] (Figure 3d). Similarly, El-Zeiny & El-Kafrawy [5] indicated that the increase in the percentage of agricultural and urban lands contributed to an increment of nutrient concentrations in lake ecosystems.…”
