Numerical Study on the Effects of Regional Groundwater Flow on the Contaminant Migration through an Inactive Supply Well as a Preferential Flow Pathway

<div>The schematic of well that acts as a preferential flow pathway: (a) vertical flow and contaminant migration through a well with regional groundwater flow in inactive phase; (b) deterioration of water quality in pumping phase with regional groundwater flow.</div>
