New Report on Environmental Decision Making under Uncertainty

By Everett & Associates on Apr 19, 2013 at 06:02 PM in Environmental Issues

L. Everett & Associates recognizes the importance of understanding and assessing uncertainty associated with the various sources of information and data that has to be considered in each case or project.


U of California Study Highlights Environmental Risks from Fracking

By Everett & Associates on Apr 12, 2013 at 10:17 AM in Environmental Issues

L. Everett & Associates is very active addressing the environmental aspects of hydraulic fracturing or "fracking".


Regulating Exposure to Toxic Chemicals

By Everett & Associates on Apr 06, 2013 at 09:06 AM in Environmental Issues

One of the dilemmas of environmental regulation is that EPA stipulates permissible levels for inadvertent exposure to certain toxic chemicals (such as from vapor intrusion from subsurface contamination) but OSHA allows much higher levels of exposure of the same chemicals for purposeful exposure in an occupational setting.


Vapor Intrusion Paper Co-authored by Dr. Everett

By Everett & Associates on Jan 30, 2013 at 09:06 AM in Environmental Issues

This paper coauthered by Lorne Everett, Mark Kram and Peter Morris is generating lots of conversation about temporal variability of the processes that cause vapor intrusion.


Soil Vapor/Vapor Intrusion Conference in Jacksonville chaired by Lorne Everett

By Everett & Associates on Dec 10, 2012 at 03:19 PM in LEA Announcements

We are looking forward to the Symposium on Continuous Soil Gas Measurements: Worst Case Risk Parameters sponsored by ASTM International in January 2013. This symposium, chaired by our own Lorne Everett, will focus on newly developed capabilities for continuous soil gas monitoring of volatile contaminants for vapor intrusion investigations.


Thoughts on Daubert and Expert Testimony

By Everett & Associates on Oct 24, 2012 at 12:27 PM in Environmental Issues

In the post-Daubert legal system, the need for reliable expert testimony in civil trials has taken great prominence. Couple this need to the increasing technical complexity of modern life (thus the parallel increase in complexity of issues tackled by the courts) and it is easy to appreciate the growing demand for experts who understand the legal framework, have impeccable credentials, and who can clearly communicate the significance of technical findings to attorneys, clients, and the trier of fact.


Using Tree Rings to Determine the Age of Groundwater Contamination

By Everett & Associates on Oct 24, 2012 at 12:27 PM in Environmental Issues

The application of dendroecology to environmental forensics is an exciting development because the method comes with a built in calendar for dating contamination events: tree rings!


Order out of Chaos: Geostatistics in Environmental Science

By Everett & Associates on Oct 13, 2012 at 12:30 PM in Environmental Issues

The voluminous and ubiquitous tables of analytical data in environmental reports might just hold the key to deciphering some of the most common questions that arise in environmental disputes: where does this contamination come from? Are there different sources of contamination at this site? How much is mine & how much is yours?


Antidepressants make for sad fish

By Everett & Associates on Sep 22, 2012 at 12:30 PM in Environmental Issues

According to a recent study reported at a meeting of the Society of Environmental Toxicology and Chemistry, certain fish are being exposed to trace amounts of antidepressant drugs in waterways and they may be getting too relaxed for their own good.


Communicating Complex Technical Information

By Everett & Associates on Aug 07, 2012 at 03:22 PM in Environmental Issues

Our work involves subsurface environments and somewhat complex concepts of moisture and contaminant flow through the vadose zone and groundwater. Needless to say, this can lead to challenges when trying to communicate our findings to a lay audience such as a community group or judge or jury.
