Panglao is a small island in the central part of the Philippines and well-known for its world-class beaches and coral reefs. These attract millions of tourists each year thus providing business opportunities and employment, a significant source of revenue for the local economy. Moreover, this island lies in a region with high biodiversity. However, the escalating activity is so alarming that the negative effect to the local environment is very much prevalent but not easily perceivable. Analysis and measurement of physico-chemical parameters of the groundwater revealed high levels of human-induced contaminants. This subterranean pollution was attributable to the leakage of septic tanks, artificial application of disinfectants as well as infiltration of saltwater from the ocean due to over-extraction of groundwater in order to meet the increasing demand for water. The community within the area was oblivious because human impacts to the environment appear to be virtually absent. These findings clearly suggest the concealed vulnerability of the groundwater resources from human activities. Higher standard for the coastal development plan, strong implementation of environmental policy and immediate government action is deemed necessary.
