When people talk about water research mainly talking about drinking water, water quality at the intake point, and may be technologies for water processing beside campaigning to save water to avoid water shortage. More important is looking at the source water which is water catchment areas, forest. When we study wildlife and habitat protection and conservation, directly we protect the source of water by protecting and conserving their habitat where water are kept. Forest keeping 70% of rain water then released slowly as we need through river systems and evaporation. We need to study the hydrology in the forest and water catchment areas. We also need to monitor the water quality. Not just measuring ecological parameters like pH, BOD, COD, DO, NH3 etc. We need to look at bioindicators for clean waters or bioindicators that reflecting water contamination.Those bioindicators can be good biomonitoring agents. If water are polluted the processing fees are expensive because they need good technologies, therefore we need to look for the best way of cleaning water by using biota (plant and animals). All those research about water usually forgotten and many are focus to what they can see and technology that currently available. Basic of water studies involve the origin and water cycles and all ecological processes along the way. We need ecologist to help.
