Combined Well Multi-Parameter Logs and Low-Flow Purging Data for Soil Permeability Assessment and Related Effects on Groundwater Sampling

Cost-effective remediation is increasingly dependent on high-resolution site characterization (HRSC), which supposed to be necessary prior interventions. This paper aims evaluate the use of low-flow purging and sampling water level data in estimating horizontal hydraulic conductivity soils. In a new quali-quantitative view, this procedure can provide much more information knowledge about site, reducing time costs. case high heterogeneity along well screen, whole procedure, as estimation method, could less effective rigorous, with related issues time. The result showed significant permeability weighted sampling, different results pump position changes screen. proposed study confirms phenomenon field data, demonstrating that multiparameter logs might helpful detecting behaviour low-permeability layers their effects sampling. A lower correlation between estimations LeFranc test was associated longer wells P43, MW08 MW36, due presence clay layers, obtained differ for almost one order magnitude increases (by than 16 min). However, some precautions work, become representative shorter important hydrogeological parameters such many tests results.
