HYDROGEN ION CONCENTRATION (pH)


Fig. 1. Increasing pattern of monsoon water salinity at different spots from 2006 to 2008.

Spot 1: The pH of water at this spot varied from 7.0 to 7.7. The maximum pH was recorded in summer 07 and minimum was recorded in monsoon 06. The yearly average pH values 7.2, 7.3 and 7.3 were recorded in 06, 07 and 08 respectively. During the period of study more or less uniform data were observed at this spot.

Spot 2: At this spot the pH of water was found to vary from 7.0 to 7.5. Maximum pH value was recorded during summer and monsoon 07, while the minimum value was recorded during post monsoon 06. During the study period the yearly mean pH values 7.2, 7.4 and 7.3 were recorded in the year of 06, 07 and 08 respectively. More or less uniform data were observed at this spot during the study period.

Spot 3: At this spot the range of pH value of water was recorded from 7.0 to 7.6. Maximum pH value was recorded during summer 06 and 07, while minimum pH value was recorded during monsoon, post monsoon 06 and winter 08. The data were more or less uniform at this spot during the study period. The mean values of the year 06, 07 and 08 were recorded 7.3, 7.3 and 7.2 respectively.
