Risk Of Well Water Pollution From The Surface Of
A Recharge Area

Abstract
An aquifer acts as a pollution pathway between the source of pollution and the
receptor. In this paper the risk of pollution of well water from a highway as the
pollution source on a surface of a recharge area is estimated and discussed. A
highway is a source of long-term pollutant release resulting from highway runoff
and also the momentary release through spillage of hazardous materials. The
solute transport through the individual segments of the system has been
investigated in order to evaluate the probable pollutant concentrations in the well
water. The study showed that the long-term low-level pollutant release presents
almost no risk whereas the momentary releases of large quantities of hazardous
liquids present a high risk to well water quality.
Keywords: wellhead protection area, highway runoff, groundwater pollution,
solute transport.
1 Introduction
Groundwater is one of the most important sources of drinking water. Various
activities in a recharge area of a groundwater pumping station pose a threat to the
quantitative and qualitative state of well water and ground water in general.
Furthermore, any activity on top of an aquifer or in its recharge area poses a
threat to groundwater. The risk of well water pollution from such activities
should be properly assessed. Consequently, measures should be taken in order to
protect the groundwater bodies from pollution, with special emphasis being put
on the protection of the recharge areas of existing wells. However, the flat
surface of a typical lowland aquifer is predominantly used for agriculture and
urbanization, and it is also particularly convenient for building transport
infrastructure. These sorts of conflicts of interests can be resolved using risk
