| 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). |
