Abstract– In the present study, physico-chemical parameters of Ambhobasabadi chour was studied during Jan-2020 to Dec- 2020. The chour is situated in Puraini block of Madhepura district. The studied parameters were temperature, pH, transparency, E.C. TDS, DO, BOD, COD, Alkalinity, Nitrate, Phosphate and Chloride. The temperature of chour water ranged between 16.8oC to 33.4oC. pH ranged between 6.8 to 8.1. Transparency was maximum in May (72cm) and E.C. was also maximum in May (191.6). TDS ranged in between 162.4 to 265.8. Maximum value of TDS was in the month of May. Maximum alkalinity was observed in May (155.4mg/l) and minimum in the month of December (120.4mg/l). DO ranged in between 5.4mg/l to 9.6mg/l and BOD ranged in between 3.2mg/l to 5.1mg/l. The value of COD was maximum in the month of February (6.6). Nitrate ranged in between 0.91mg/l to 1.30mg/l and phosphate ranged in between 1.48mg/l to 1.95mg/l. Chloride was maximum in the month of May (48.8mg/l) and minimum in the month of October (38.5mg/l).
Key words: Ambhobasabadi chour, pH, DO, BOD, COD
