การตรวจสอบคุณภาพน้ำในอำเภอป่าพะยอม จังหวัดพัทลุง

Abstract

             The aim of this research is to study water quality from Papayom canal, wells water and ground water in Papayom  district, Phattalung.  The water samples were collected from 5 points, 3 times during December 2004 - April 2005
            The average of 13 parameters of the water sample from Papayom canal are : temperature 27.91oC, pH 7.49, dissolved oxygen (DO) 4.16mg/L, biochemical oxygen demand (BOD) 0.51 mg/L, total coliform bacteria 15 MPN/100 mL, nitrate nitrogen (NO3- - N) 5.46 mg/L, ammonia (NH3-N) 0.05 mg/ L, acidity 8.60 mg/L, alkalinity 104 mg/L total solid (TS) 92 mg/L, total suspended solid (TSS) 15 mg/L, total dissolved solid (TDS) 89 mg/L, and the concentration of Lead (Pb), Cadmium (Cd), Copper (Cu), Zinc (Zn) and Iron (Fe) are 0.141, non-detect (n.d.), 0.038, 0.980 and 0.703 mg/L, respectively.
              The average of 9 parameters of the water sample from water wells are: temperature 27.31 oC, pH 6.73, DO 1.84 mg/l, total hardness 150.23 mg CaCO3 /L, conductance 255.20 μS/cm, TS 141 mg/L, TSS 27 mg/L, TDS 110 mg/L, and the concentration of Fe, Pb, Cu, Cd and Zn are 0.330, 0.024, 0.034 , 0.051 and 0.051 mg/L, respectively.
              The average of 9 parameters of the water sample from ground water are : temperature 28.36 oC, pH 7.38, DO 2.45 mg/L, TS 125 mg/L, TSS 20 mg/L, TDS 134 mg/L, total hardness 216.35 mg CaCO3 /L, conductance 596.53 μS/cm, and the concentration of Fe, Pb, Cu, Cd and Zn are 0.630, 0.020, 0.130, 0.044 and 0.735 mg/L, respectively.
                 For this research , the water quality in PaPhayom District, Phattalunge Province is satisfactory enough for consumtion.
