| Summary: | Groundwater in fractured metasedimentary rock in Malaysia is a potential source of water for drinking and industrial
uses. Industries including agricultural processing, mineral water bottling, manufacturing and golf courses pumped
the water from the underlying fractured rocks. Fifty eight tubewells belong to private companies operating in various
places in West Coast of Peninsular Malaysia were evaluated for their yield and quality of water. Rotary percussion
methods were used for the drilling to a maximum depth of 200 m. The productivity of the wells and the characteristics
of the aquifer were evaluated by pumping test using both the constant discharge rate and steps drawdown methods. The
average yield of the wells at allowable drawdown of 40 m was found to be 416 m3 per day. Results from water quality
analysis indicated that the water was fresh with an average total dissolved solids (TDS) concentration of 101 to 150
mg/L. The hardness of the water varies from as low as 13 mg/L to a maximum of 353 mg/L. On the average, the water
was moderately hard with the average hardness value of 80 mg/L. The water facies of the groundwater was found to be
of calcium-sodium-bicarbonate water. |
