Ground Water Environment Justification of Sampling Locations Sample Clauses

Ground Water Environment Justification of Sampling Locations. The locations selected for ground water analysis along with their distances and directions from the site are given in Table 3-10. Photographs showing the sampling locations are also presented in Annexure 10. The analysis results are presented in Table 3-11. 1 pH pH scale 6.5-8.5 NR 7.94 7.45 7.72 8.03 2 Temperature o C - - 27 29 27 27 3 Turbidity NTU 1 5 <0.1 <0.1 <0.1 <0.1 4 TDS mg/lit 500 2000 2820 812 644 1060 5 Electrical conductivity µmho/cm - - 4600 1324 1254 1824 6 COD mg/lit - - <5 <5 <5 <5 7 BOD mg/lit - - <3 <3 <3 <3 8 Phenol mg/lit 0.001 0.002 <0.001 <0.001 <0.001 <0.001 9 Chlorides mg/lit 250 1000 964 256 280 395 10 Sulphates mg/lit 200 400 365 115 30 47 11 Total Hardness mg/lit 000 000 000 220 260 430 12 Ca++ Hardness mg/lit - - 210 64 78 174 13 Mg++ Hardness mg/lit - - 740 156 182 256 14 Total Alkalinity mg/lit 200 600 230 130 180 250 15 Nitrate mg/lit 45 NR 20.6 23.8 7.1 3.8 16 Fluoride mg/lit 1 1.5 1.48 1.33 0.47 0.81 17 Sodium mg/lit - - 482 165 135.5 155 18 Potassium mg/lit - - 15 15.6 8 10 19 Calcium mg/lit 75 200 84.2 128.2 31.3 69.7 20 Magnesium mg/lit 30 100 179.8 37.9 44.2 62.2 21 Salinity mg/lit - - 1738 460 504 712 22 Total Nitrogen mg/lit 0.5 NR 4.80 4.70 4.30 0.91 23 Total Phosphorous mg/lit - - <1 <1 <1 <1 24 Dissolved Oxygen mg/lit - - 3.5 3.2 3.6 3.3 25 Ammonical Nitrogen mg/lit NS NS <0.01 <0.01 <0.01 <0.01 26 SAR - - - 6.76 3.28 3.64 3.24 27 Heavy Metals a Arsenic (as As) mg/l 0.01 0.05 <0.002 <0.002 <0.002 <0.002 b Cadmium (as Cd) mg/l 0.003 NR <0.003 <0.003 <0.003 <0.003 c Cromium (as Cr) mg/l 0.05 NR <0.003 <0.003 <0.003 <0.003 d Copper (as Cu) mg/l 0.05 1.5 <0.05 <0.05 <0.05 <0.05 e Cyanide (as CN) mg/l 0.05 NR <0.003 <0.003 <0.003 <0.003 f Iron (as Fe) mg/l 0.3 NR 0.14 <0.1 <0.1 0.13 g Lead (as Pb) mg/l 0.01 NR <0.01 <0.01 <0.01 <0.01 h Mercury (as Hg) mg/l 0.001 NR <0.001 <0.001 <0.001 <0.001 i Manganese (as Mn) mg/l 0.1 0.3 <0.04 <0.04 <0.04 <0.04 j Nickel (as Ni) mg/l 0.02 NR <0.02 <0.02 <0.02 <0.02 k Zinc (as Zn) mg/l 5 15 <0.08 <0.08 <0.08 <0.08 28 Total Coliform MPN/100ml Shall not be detectable in any 100 ml sample Absent Absent Absent Absent 29 Faecal Coliforms MPN/100ml Shall not be detectable in any 100 ml sample Absent Absent Absent Absent NS: Not Specified, NR: No Relaxation  All parameters are within permissible limit  The formation is having low storativity since it is made up of fine sand and silt thus supply will always be limited.
