Cameron Highlands is a mountainous area subjected to torrential tropical showers. It extracts 5.8 million liters of water per day for drinking supply from its rivers at several intake points. The water quality of rivers in Cameron Highlands, however, has deteriorated significantly due to land clearing for agriculture, excessive usage of pesticides and fertilizers as well as construction activit...

Monitoring microbial water quality is essential for recreational beaches in order to protect human health. To evaluate the relative importance and impacts of various types of non-point microbial sources at a subtropical beach (Hobie Beach, Miami, USA), we utilized a coastal ocean circulation model (Delft3D) with a microbe transport-fate model. Those non-point sources include beach sediment, dog...

Perfluorinated Compounds (PFCs) have recently been detected in a wide range of places. This study examined contribution of the non-point source (NPS) to PFCs in rivers. NPS contribution of PFCs has not been focused much so far. In this study, samples of river water were collected from Tsurumi River at a fixed location during low and high levels of river flow (due to rainfall) and their concentr...
