Data represents mean values ± standard deviation. EC: electrical conductivity (mS/ cm); TDS: total dissolved solids (g Lˉ1); SM: suspended matter (mg Lˉ1); COD (mg Lˉ1): chemical oxygen demand; BOD5: biological oxygen demand (mg Lˉ1); Total coliform and Fecal coliform (UFC/100 mL). anions, cations and total P and N are measured in (mg Lˉ1).
