Health diagnosis of groundwater environment based on a projection pursuit model Available to Purchase

Pollutants from various sources are entering groundwater systems due to changing land use and because groundwater environments are deteriorating at various scales worldwide. The health status of a groundwater environment can be used to indicate the degree of deterioration under natural or manmade stresses. This study proposes a concept for groundwater environment health and sets up an assessment index system to diagnose the health status of a groundwater environment based on a Bossel sustainable development index framework. The index system covers six basic categories (survival, effectiveness, freedom, security, adaptation and coexistence), which indicate various aspects of the health status of a groundwater environment. A projection pursuit (PP) model is developed for the assessment of groundwater environments and PP grade evaluation (PPGE) was used to evaluate the health status of a groundwater environment. The model was applied in Western Jilin province, China as a case study for groundwater environment management.
