WATER QUALITY IN DIFFERENT AREAS OF TIMIS RIVER COURSE IN ROMANIA.

Researchers have been conducted in the Timis River, which springs from the Semenic Mountains, in the western part of Romania. On its course on Romania's territory were established 6 sampling stations (Accumulation Three waters-Feneşti Confluence, Teregova, Lugoj-CFR Bridge, Lugoj-Timişana Confluence, Şag and Grăniceri) where analyzes were made of the chemical composition of the water. Analysis of the results showed an increase from upstream to downstream of 5 days-biochemical oxygen demand (B.O.D.5) (from 1.75 to 3.66 mg/l), also the accumulation of nitrates (from 1.53 to 3.08 mg/l), nitrites (from 0.01 to 0.10 mg/l), chloride (from 2.50 to 8.51 mg/l) and water hardness (from 1.12 to 6.02 dH°).
