GeoEnviro Training Professionals Inc. training

Where Science Meets Sustainability: Your Environmental Education Hub! GeoEnviroPro does in-person and virtual workshops throughout the year, where our senior team leads attendees through in-depth topics and discussions. Past workshops have included the annual Risk Symposium, BC Contaminated Sites Regulation (CSR) Update and Navigating the CSR.

In-Situ and Ex-Situ Thermal Desorption (ISTD and ESTD) are technologies based on thermal conduction that can effectively treat organic contaminants, independently of large soil heterogeneity. One of its applications is for contaminated properties in urban areas and under existing buildings. The main principle of the technology resides in installing a network of steel pipes acting as a air/soil heat exchanger to heat up the soil to temperature and pressure conditions at which the contamination is volatilized and recovered above- ground for further treatment.

Soil Vapour Intrusion Investigation: Human Health Risk Assessment for a former Dry-Cleaning Facility; Presenting Soil Vapour Intrusion Investigation including topic introduction, vapour pin installation, ambient air and soil vapour sampling, results, and discussion. In the context of the site and aimed at completing a human health risk assessment.

Polycyclic Aromatic Hydrocarbons (PAHs) are ubiquitous contaminants emanating from multiple sources in the environment. When conducting environmental monitoring of PAHs, it is imperative to examine sources of PAHs to know if they are coming from the source or sources you are investigating. This presentation will cover the fundamentals of what chemical fingerprinting of PAHs works, the basis of diagnostic ratios and a walk through of an online data portal that allows everyone to chemically fingerprint and determine sources of the PAHs in their environmental data.

Does the CSR and resources spent reflect society’s current risks and priorities? Discussion with a long time practitioner with an industry perspective.

A fundamental step in risk assessment is establishing what level of chemical contamination is safe. Toxicity reference values (TRVs) represent an exposure dose that people can safely be exposed to without adverse effects. Toxicity reference values are used to derive drinking water and soil quality guidelines, and to calculate hazard quotients (HQs) that determine risk to human health in risk assessments. Although TRVs are regularly used, they are often not completely understood. This presentation will explain how TRVs are derived, where you can find TRVs, and identify differences in TRVs derived by different agencies. Case studies will demonstrate why strong risk assessors should consider the basis of TRVs in their risk conclusions.

Environmental Consulting – business or a practice or both? What is involved in the business of consulting? This talk is a brief overview of how we can become better environmental consultants without compromising our values, ethics as well as keeping business aspects in mind.

SLR’s 2021/2022 award winning CFB Comox project implemented novel in-situ and ex-situ PFAS management methods (amendment and thermal treatment, respectively). To reduce PFAS concentrations in downstream site surface water, the highest concentration materials were targeted for management. This presentation will introduce project design and provide an update on environmental conditions three years after implementation.
