5 Ways to Improve Your Next Aquifer Test Results

A thorough hydrogeologic site characterization is critical to the design of many engineering projects, from mine dewatering and groundwater treatment systems, to industrial water wells and aquifer storage projects. An aquifer test is a key component of the characterization process, yielding hydrologic data vital to system designs. When tasked with conducting an aquifer test, many … Continued

How Much to Purge?

A modeling approach to purge volume guesstimation A novel approach to determine an optimum groundwater purging and sampling strategy was published last year in the Journal of Hydrology (Qi et al, 2017). This paper uses a numerical model to estimate the “representativeness” of the groundwater sample at different purge times. The model was tested against … Continued

ORP Field Measurements Reporting Redox Potential (Eh) Correctly

Many practitioners are familiar with using multiparameter water quality meters in the field which incorporate ORP (oxygen-reduction potential) sensors. But ORP measurements are often reported from field probe measurements without the necessary conversion made to standardize readings to a common reference. Most manufacturers, including In-Situ, use a silver/silver chloride (Ag/AgCl) electrode in potassium chloride (KCl) … Continued
