A method for the stochastic design of groundwater quality observation well network is presented. As well as mandatory leak detection systems like SIRA, under NSW guidelines site operators must have groundwater monitoring wells installed and then monitored every six months. The main purpose of groundwater monitoring wells is to obtain representative groundwater data, which may include groundwater level, hydraulic conductivity, and groundwater sample analysis data. Berkeley Geological Services Unit . These issues may include the following: Therefore, the monitoring well design process needs to meet the following requirements, 1) well with sufficient strength to withstand tension induced by construction process; 2) well not adsorb, desorption, leach out any chemical composition to change the water quality; not cause pollution of groundwater; 4) easy to use and cleaning; 5) cost-effective. 9 Well design should be based on low installation and running costs while not affecting well performance. Proper design and installation also require sufficient study on site geological, chemical, microbial and other environmental data.
