Characterization of a Contamination Event,d for sampling pore water. Sampling of the saturated medium should allow to obtain a three-dimensional reconstruction of the contaminated areas. Hence, recommendations on the spatial distribution of monitoring wells, on the available options for vertical sampling and on well-purging prior to samplin

Human Health Risk Assessment,f appropriate interventions). The risk assessment itself can be carried out at an increasing degree of detail, through a tiered approach, illustrated in the chapter. A relevant focus of this chapter is the calculation of the concentration at the point of exposure via the determination of the natural

Remediation of Contaminated Groundwater, strategies available for the management of a groundwater contamination event, and provides valuable information to support the choice of the most suitable approach. The presented strategies include: free product recovery for light non-aqueous phase liquid removal; vacuum enhanced extraction; subsur

Prematurity/Extreme Prematurityparameters that characterize an aquifer’s storage capacity are porosity and storativity. While the former is indicative of the total amount of water that can be stored within a porous medium, the latter indicates the fraction that can be released. Both these notions apply to any aquifer type althoug

In particular, in the case of confined aquifers, flow is a function of specific yield and transmissivity, as is the case even for leaky aquifers, whose hydrodynamic behavior is, however, also affected by the leakage between aquifers (quantified by the leakage factor)

Pediatric Electrical Nerve Stimulationons describe, respectively, the transient and steady state solutions of the groundwater flow equation for confined aquifers. Hantush and Jacob, instead, derived the transient analytical solution for leaky aquifers, while De Glee formalized the steady state solution. In the case of unconfined aquifer

Clearly, this interpretation relies on a number of ideal hypotheses being satisfied; this chapter also illustrates how to interpret pumping tests in the presence of factors that cause a deviation from the ideal behavior (e.g., finite, as opposed to infinite
