3.3 Strategies for Groundwater Pollution Prevention
and Control
Groundwater pollution, concealed and complex as it is, can cause environmental
and ecological damages that are hardly reversible. Groundwater pollution prevention and control should place more emphasis on prevention than control, and pay
attention to protecting from pollution sources and blocking pollution processes (Lu
et al. 2012). Using the dual interface method, groundwater pollution processes are
identified and analyzed, and based on the results of groundwater pollution source
intensity evaluation, targeted strategies are developed to prevent and control pollution from potential and existing sources respectively (Fig. 3.16). The strategies
will identify the level of seepage control in potential sources of pollution, and
provide programs for classification and combination of prevention and control
techniques applicable to existing sources of pollution (Li et al. 2016).
3.3.1 Potential Sources of Pollution
The prevention and control of pollution from potential sources should place
emphasis on source prevention, which mainly involves the protection from pollution sources and the determination of site seepage prevention levels (Yang et al.
