Overview
Safe drinking water and healthy ecosystems are topics of critical importance. Making decisions about policy and management requires reliable scientific information. Groundwater is vulnerable to contamination at any point along the ground water flow system, and nature of contamination sources varies depending on the properties and proximity of contaminant sources, characteristics of the contaminants, and time variation of loads and demands on aquifers. Assessment of man made and natural contaminants to groundwater range from simple to complex, from qualitative to quantitative, from generalized overview to rigorous and costly. Cost, scientific defensibility, time frame and acceptable uncertainty are factors in defining the scope, character and value and eventual use of any study.
There are common approaches used to evaluate factors controlling the vulnerability of ground water resources to contamination. This course reviews the strengths and weaknesses of these approaches at providing scientifically defensible information for the management and policymaking process.
In order to earn PDH credit for this course, the reader will need to pass a multiple choice quiz of ten (10) questions.
