WATER QUALITY
• Piezometer : a capped 4cm x 3m PVC pipe placed into an auger hole, the pipe is open at the bottom. The water table is measured by hand or electronically (potentiometry).
• pH and conductivity are the normal water quality measurements.
• Lab or Field measurements :
Cl- : SO42- < 4 : 1 ASS source of SO42-
Cl- : SO42- < 4 : 1 ASS source of SO42-
If there is a marine source.
Cl- : SO42- = 7.2 :1 (mass) marine
& brackish H2O.
Cl- : SO42- = 7.2 :1 (mass) marine
& brackish H2O.
• Field measurements of SO42-
use a colorimeter.
