GPro Talks

The GPro talk series is a weekly webinar allowing attendees to learn about specific topics related to environmental sciences. Each talk is lead by our senior specialists who’ve spent years in the field gathering experience and knowledge.

Past talks are available to purchase individually or through all access memberships.

GeoEnviroPro Talks  will be held every Wednesday at 10 am PST. The topics will be announced a week in advance. We have combined experience with every aspect of practice – from the excavator to the courtroom – and have been involved throughout the evolution of the contaminated field science and regulations in BC. Now distilled freely into 30 minute chunks. These sessions are FREE!

After 35+ years of site investigations and cleanup, we’ve seen a few things out there…and it’s time to share!!

    Comparing Data to Standards Using Statistics: Why and Howkeyboard_arrow_down

    Many regulations compare a mean or percentile of observed data to a standard or guideline.  If the mean exceeds the standard, the soil/water being sampled is out of compliance.  If more than an allowed percentage (say 10%) of observations exceed the standard, the soil/water is out of compliance.  Such comparisons lead to elevated false positives, false statements of non-compliance.  The statistical approach compares a confidence limit on the mean or percentile rather than the parameter itself to the standard value.  Why should a confidence limit be employed?  What are the drawbacks to using the observed mean or percentile?  After answering these questions, the method for comparing a confidence limit to a standard is illustrated.

Conceptual Site Model – Introduction


Why are we doing this?

The objective of GeoEnviroPro Talks is to further support the application of solid environmental science in the real world, and to introduce new concepts to solve old problems. We want to build a community of contaminated site practitioners and look forward to helping you on your professional journey.

Some of BC’s most experienced remediation practitioners, including Dr. Reidar Zapf-Gilje and Hydrogeologist Guy Patrick, are pulling together over 104 years of cumulative experience to have some frank, honest, focused talks on critical issues to practicing professionals today.

We’ll spend ½ hour each week presenting and discussing important and interesting topics with you – topics relevant to environmental professionals. New technical tools (and some old ones!), regulatory issues, case studies, remediation, emerging (and emerged!) contaminants, and risk assessment. We promise to include time for dialogue and questions.
