Results of Measurement of pH and EC in water bodies at 2 points (upper stream and lower stream) on the River Volta and 2 wells in the city of Accra from 29th November, 2012 to 2nd December, 2012

During the period under consideration, the pH and EC of identified water bodies were monitored. From 29th November, 2012 to 2nd December, 2012, the coordinator of FOLENS GHANA participated in a symposium organized by CELENS in Japan.

Measurement of pH and EC in water bodies
The pH, EC of the River Volta. Data were collected from two (2) points along the river (Upper stream and Lower stream). The results are indicated below:
