ABSTRACT |
The continual extraction and indiscriminante use of groundwater for residential sectors could cause a decrease in the groundwater
level in Parañaque and Las Piñas City; and allows saltwater to penetrate into the aquifer due to the proximity of Manila Bay. This study
models the present condition and extent of saltwater intrusion in the aquifer bounded by Parañaque River and Manila Bay. The model
is simulated using a 3D finite element modeling software (FEMWATER) that is capable of modeling the groundwater flow condition in
the aquifer. Moreover, the model can also be used to predict the future condition of the aquifer for better groundwater management.
This study aims to raise public awareness of the extent of the problem and the possible side effects incurred. The model will serve as a
basis for further studies on remediation techniques and saltwater intrusion control in the coastal aquifer of Parañaque City. |
