A New Book on Soil Gas & Vapor Intrusion from Dr. Lorne Everett - Continuous Soil Gas Measurements: Worst Case Risk Parameters

A New Book on Soil Gas & Vapor Intrusion from Dr. Lorne Everett - Continuous Soil Gas Measurements: Worst Case Risk Parameters
By Everett & Associates on Jan 15, 2014 at 11:05 AM in LEA Announcements

Our CEO, Dr. Lorne Everett has published a new book from ASTM, "Continuous Soil Gas Measurements: Worst Case Risk Parameters" coedited with Dr. Mark Kram of Groundswell Technologies. The book summarizes state-of-the art thinking on vapor intrusion by an international team of authors from the USA, Canada, Brazil, United Kingdom, Germany and other nations. Interest in vapor intrusion has intensified by recent studies which suggest that prevailing sampling programs may fail to fully characterize vapor intrusion problems due to extreme spatial and temporal variability of VOCs and methane at contaminated sites.

New EPA Guidance on Vapor Intrusion

By Everett & Associates on Jun 19, 2013 at 03:03 PM in Environmental Issues

The US Environmental Protection Agency has issued two draft guidance documents concerning vapor intrusion. Vapor intrusion is the migration of volatile chemicals from contaminated soil or groundwater into overlying buildings. One important concept that is emphasized by EPA is spatial and temporal variability of indoor air concentrations. LEA has been a vocal advocate for appreciating and accounting for this variability when addressing vapor intrusion problems.

Nitrates In Groundwater: A Persistent Nationwide Problem

Nitrates In Groundwater: A Persistent Nationwide Problem
By Everett & Associates on May 20, 2013 at 08:46 AM in Environmental Issues

One of the great accomplishments of the environmental movement in the US has been to secure clean drinking water for the vast majority of Americans and to protect the waterways and aquifers that serve as sources of clean drinking water. In fact, The Clean Water Act of 1972 and The Safe Drinking Water Act (SDWA) of 1974 are considered two of a handful of federal laws that ushered in the modern era of environmental protection. Considering all the progress that has been made, it is easy to forget that the work of the SDWA is not done. It is not just third-world problem: many folks right here in the U.S. still lack access to safe drinking water.
