This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant, or impurity in the groundwater, in which case it is more likely referred ... Case Study: Telford Borough, PA Main content of document 2D seepage modeling is valuable in many engineering applications. Geotechnical engineers use seepage modeling to estimate groundwater flows through structures, or to evaluate stability of water retention structures. Environmental engineers use seepage modeling to analyze contaminant transport or infiltration through landfill covers, for example.Decline in groundwater quality is the challenge I have observed and experience in my country. Groundwater systems are particularly important in places where no rivers flows on the surface. In Yucatan, Mexico, for example, there are no rivers on the surface but we can find the Yucatán Peninsula Aquifer one of the biggest aquifers in the world. For example, it is showed that deep groundwater from basaltic
