| Summary: | The study area is located in Machang, North Kelantan - Malaysia. TheNorthKelantanplain
is covered with Quaternary sediments overlying granite bedrock. The drainage system is dendritic
with the main river flowing into the South China Sea. Hydrogeochemical method was used to study
groundwater of shallow aquifer characters within the area. Based on water samples analysis collected
from the study area, it can be deduced that the cations and anions concentration are good for
..domestic use except in the southern region which the nitrate concentration is higher (more than 20
'mg/l) compared to the northern region (relatively zero). The areas that possibly possess nitrate-con.
taminated groundwater have been mapped along with groundwater flow patterns. The southern and
middle part of the study area has an east to west groundwater flow pattern, making it impossible for
contaminated water from the southern region to enter the northern area, despite in the northern area
has lower elevation. |
