This document discusses water pollution management in Cambodia. It outlines sources of water pollution such as point source pollution from pipes/sewers and non-point source pollution from agricultural/urban runoff. Causes of water pollution include industrial/sewage waste, chemical fertilizers and pesticides from agriculture, and leakage from sewer lines. Effects are death of aquatic animals and disruption of food chains. Solutions proposed are reducing waste/chemicals, planting near water bodies, and managing pollution.
