| description | The impact of Kampong Kelichap solid waste dumping site on groundwater
of an unconfined aquifer was investigated. The investigation involved the analysis of
groundwater quality and the estimations of leachate or contaminants movement
which included the flow direction and velocity. The leachate or contaminants
movement were assumed to be similar to the groundwater movement in the study
area. Groundwater level and water quality were monitored from August of 2003 to
June of 2004 in nine wells (SI to S9) located upstream and downstream of the study
area. The measured water quality parameters were pH, temperature, turbidity,
conductivity, dissolved oxygen (DO), total dissolved solids (TDS), ammonia
nitrogen (NH3-N), sulfate, biochemical oxygen demand (BOD5), and chemical
oxygen demand (COD). Contaminants concentration distribution in groundwater has
been mapped or contoured using geostatistical analysis. Groundwater and
contaminant movement or flow characteristics were estimated using water table
contours, correlation surface analysis, and numerical models. The numerical
modeling was conducted by using MODFLOW in conjunction with MODPATH and
MT3D. Field and laboratory results showed high concentrations of conductivity,
COD, NH3 -N and TDS in the downstream groundwater. Field measurements,
laboratory analyses, and simulated models showed similar results in which the
contaminated wells were S3, S4, S5, and S6. Conductivity, COD, and NH3-N
concentration contours suggested the dumping site as the main source of groundwater
contamination in the study area. The changes in the patterns on COD concentration
contours, the water table contours, the correlation surface analysis, and the numerical
models showed that the contaminants and groundwater were traveling mainly toward
the southwestern boundary with an average direction of 196 °, 199.5 °, 242.7 °, and
228.4°, respectively, as measured clockwise from the north. The estimated
contaminated groundwater velocities from the correlation analysis and numerical
model were ranging from 315.5 to 359 m/yr and 174 to 284 m/yr, respectively. |
