The American Society of Civil Engineers (ASCE) will conduct a public comment period on the update to ASCE/EWRI 70-XX Aquifer Hydraulic Properties. The public comment period will be held from June 12 to July 28. This is a standard guideline for estimating the hydraulic properties of a groundwater system by inverse numerical modeling of aquifer pumping tests.
This guideline is applicable to situations where inverse methods based on analytical solutions for aquifer response to pumping are not applicable, which might occur when the pumping rate is time dependent, the hydrostratigraphy of the groundwater system is complex, or boundary conditions are present that influence aquifer response.
Accessing the Public Comment System will require using or creating an ASCE web user account. For additional questions contact James Neckel, ASCE’s Codes and Standards Coordinator, at email@example.com or (703) 295-6176.
