Description

<p>In-situ tracer test has been carried out to examine the appropriate procedure and evaluation methods in sandy gravel aquifer. It is essential to understand the hydrogeological characteristics of the aquifer by applying an iterative approach in order to conduct a tracer test. The specific gravity of groundwater in the vicinity of the test section could be different from that of pumped groundwater used as tracer solution. It is found that test results have been affected by this difference. It is necessary to conduct a preliminary tracer test to determine the optimal specific gravity of tracer solution with characteristics of the tested aquifer in order to obtain appropriate results. </p>
