Result shown that polluted rate is terribly higher than the world standard rate and there is not any self- refining condition exist in this river. By measuring 10 TSS out of 12, the result shown the higher polluted rate (500ML per liter), TDS in 10 test shown this, BOD in 7 test COD in 11 test, FTU in 4 test, PH in 3 test and coli form in all tests shown this contaminated.
