Ask the Expert – Andrew Fowler

EHS Support Senior Geologist Andrew Fowler, Ph.D., has over 15 years of combined consulting and research experience developing localized and basin-scale geologic, geochemical, and hydrological conceptual models. A geology, aqueous geochemistry, and GIS expert, he thrives at managing multiple tasks for complex projects. He also has extensive experience with soil and groundwater contamination investigation, remediation, and monitoring projects both domestically and internationally.

What do you like best about the work you do?

I work at the intersection of geology, hydrogeology, and aqueous geochemistry. I thrive on addressing technical challenges that come up for our clients located throughout the United States and internationally. The broad geographic area of our work at EHS Support provides opportunities to apply my expertise on a diverse range of settings while continuing to expand my knowledge and expertise and grow professionally.

What are you currently working on?

As part of EHS Support’s strategic growth project initiative, I am exploring controls on fluoride fate and transport in groundwater at regulated sites. Lots of work has been done testing methods to mitigate fluoride in groundwater at regulated sites, but the fundamental geochemical controls are often overlooked. It is critical to highlight these fundamental controls on fluoride fate and transport to understand limitations on fluoride investigation techniques and remediation methods. Ultimately, this information will help identify shortfalls in reactive transport models often used for fluoride cleanup timeframe estimates, better plan empirical data collection and bench-scale remediation tests, and help select effective remediation techniques.

How can our clients benefit from this innovation?

This work will result in cost saving for clients through more effective allocation of resources. Understanding the fundamental controls on fluoride fate and transport in groundwater will permit clients to determine effective approach for addressing fluoride concerns early. For example, this work will help inform the correct balance between costly theoretical models and collection of empirical data, and selection of appropriate remediation strategies.
