Establishing allowable value of Electric Conductivity for monitoring groundwater based on the benchmark dose concept and its application

Recently, a number of studies have pointed out that Electric Conductivity (EC) would be a very effective measure for monitoring the quality of ground water possibly polluted by sewage sludge or incineration ash leachate. However, few have explicitly determined the allowable limit of the EC value. Therefore, we have obtained the allowable limit of EC by applying the “benchmark dose (BMD)” method.
