The press release of April 12, 2016 indicates that in March 2016, 174 Flint residents (out of 269 who participated in the original August 2015 sampling of Flint water) re-sampled their homes for lead in drinking water. The goal was to track possible improvements since the switch back to Detroit water in October 2015 and implementation of improved corrosion control (i.e., extra phosphate added beyond that present in Detroit water) starting December 2015. This work was coordinated by Virginia Tech and was funded by the U.S. EPA (EPA).

The following conclusions are based on a prelimin... More →

Trevor Nace reports that the largest and most extensive study to date on Earth groundwater has revealed surprising results regarding modern groundwater recharge rates. Ancient groundwater remains largely unknown and uncharacterized, limiting hydrogeologists understanding of recharge rates and cycle times.

Groundwater is a vital component of practically every system on Earth and has been used extensively in modern times for irrigation, potable water, and industrial activity. Further understanding of the recharge time, or the time that groundwater takes to be replenished, allows hydro... More →

Brambati, et al.(2003) deal with the geological setting, history and subsidence of the Venetian Plain. Major attention is paid to the Pleistocene-Holocene stratigraphic sequence in the Lagoon of Venice, in relation to its origin that dates back to 6 to 7 kyr BP.

Geological land subsidence has played an important role in the origin and the evolution of the lagoon, and anthropogenic subsidence, which has recently assumed a major importance for the Venetian environment. Considering also the sea level rise, 23 cm loss in land elevation has occurred in the last century, is leading to i... More →

Michael J. Schnieders reports that although initial legislation took place much earlier, the total coliform rule (TCR) of 2001 created quite a bit of stress for the groundwater industry. The TCR contained a significant expansion of microbial testing of wells and public water supplies. Beginning April 1, 2016, and earlier in some states, revisions to the TCR begin to take effect. Are you and your customers prepared?

The new revisions reflect a better understanding of coliform occurrence as well as the total coliform and fecal coliform tests. Although often misunderstood in the past, ... More →

Celine Lim reports that Canadian hydrogeologist Dr. John Cherry credits his stellar career in groundwater research, protection and management to a series of fortuitous incidents in his early years as a professional. The Lee Kuan Yew Water Prize laureate shares his journey with Eco-Business.

It was 1967, Prof. John Cherry had just joined the University of Manitoba in Winnipeg, Canada, as the first groundwater professor in Canada when he was accosted by a young woman, the only female in the entire engineering department. The American student, Barbara Lund, explained that, after spend... More →

LogitEasy created the USCS Calculator for professional geologists who need to classify soil according to the ASTM Visual-Manual Procedure (ASTM-D2488) and record only the percentage of gravel, sand, and fines in the field, without the soil group name and symbol.

The USCS Calculator allows the geologist to determine the soil group name and symbol from your field data, for use in soil descriptions when preparing boring and test pit logs. Geology students and young professional geologists are welcome to use the USCS Calculator for learning the first part of this soil classification pr... More →
