H2A’s Dr. Rangaramanujam “Ranga” Muthu, co-author of the American Petroleum Institute’s (API’s) new Microsoft ExcelTM spreadsheet tool for estimating LNAPL transmissivity using baildown test data, will present the first part of a two-part training session on the spreadsheet on February 27, 2013, from 1:00 to 1:30 PM EST. This session is only available to National Ground Water Association members (free). Preregistration at the following link, http://lnkd.in/Qz-nxr, is required by 5:00 PM EST on February 25, 2013.
The spreadsheet can be used to estimate LNAPL transmissivity in unconfined, confined, and perched conditions. The tool does not automatically estimate transmissivity from recharge data, but requires varying degrees of user consideration with regard to the data and other input parameters. The API spreadsheet tool and supporting documentation were developed to complement the new guide on LNAPL transmissivity published by ASTM (E2856-11).
