AQI (Air Quality Index) network monitoring provides general pollutant data and gives administrative support; whereas source analysis demonstrates the formulation of pollutants. The combination of two approaches gives specific evidence of ambient forecast and right solution for treatment.

FPI follows the environmental protection policy and industry development trend and implements a refined management model with watershed as a unit to achieve the goal of water quality management. The innovative establishment of a multi-dimensional correlation analysis model, a comprehensive mapping of the current situation of the discharge of pollution sources and the current water environment quality, to diagnose and identify the pollution characteristics and causes of each unit, optimize the water environment pollution prevention and control measures, and provide refined environmental supervision and assessment services to assist ecological and environmental supervision departments in building a scientific and effective integrated water environment supervision and pollution prevention system.
