We're celebrating 25 years of working alongside Marnie, our office manager, who has been a positive, dedicated, and kindhearted light in our office since the day she walked through our doors. Everyone at Global Environmental knows Marnie as a team member who is always ready to help and keeps us all on track. Outside the office, we love to see Marnie in her element, caring for the environment and never afraid to pick up a turtle 🐢 or a frog 🐸.

We hope you'll join us in wishing Marnie a happy 25 years!

Bulk GAC does not move on its own, so we built a system that makes it look easy...ish.

Whether media is heading into a vessel or coming out of one, a telehandler-mounted hopper controls the flow while the crew guides each supersack into place by hand.
It is heavy work, and it is what keeps a system's discharge within permit limits instead of raising questions later.

Global stocks the granular activated carbon and specialty treatment media these systems depend on, so when you need more, it is already here.

Compliance doesn't happen on its own. Someone has to check on it, log it, and catch problems before they turn into bigger ones.

Our field crews, OSHA 40-hour HAZWOPER-certified, handle startup and commissioning support, preventive maintenance, and troubleshooting for flow, pressure, and performance issues, with documentation that holds up for inspections and closeout. For clients running ongoing O&M programs, that includes day-to-day operation by our state-certified operators.

This is what field services looks like at Global.

Troy Zeigler, our Director of Business Operations, has a talent for making people laugh and making them think, sometimes in the same sentence.

A year in, he's known for pulling a movie or TV quote out of nowhere and turning it into an actual lesson, all while pushing the team to raise the bar.

Happy 1-year anniversary, Troy.

Good design shows up in how easy a system is to monitor, not in how it looks on paper.

Every system starts with real data: flow requirements, site conditions, and discharge criteria, sometimes backed by treatability testing to right-size it before fabrication ever starts. From there, gauges, sample ports, and remote monitoring get placed where a technician actually needs them, not just where they fit.

We design, fabricate, and install these systems in-house. It shows up in how easy they are to read once they're live in the field, keeping NPDES compliance and daily monitoring from turning into a scavenger hunt.

Robert Hikade, Project Manager, is always the first one to the shop and a self-admitted perfectionist.

Six years in, that combination is exactly why our systems run the way they should, and why the office staff can't get through a day without laughing at something he said.

Happy 6-year anniversary, Robert. Thanks for showing up early and keeping us laughing.

12 years in the field means a treatment unit has earned a proper rebuild.

When this MWT-2K2 trailer came back in for annual maintenance, the team went through everything — filters swapped, carbon vessels replumbed in series, hoses replaced, flow meter swapped out, vessels repainted, trailer lights repaired.

Nothing gets skipped. That's what it takes to put a system on a job site and actually trust it to perform.

On construction sites, groundwater management rarely goes exactly as planned. Flow rates change, contaminants show up that weren't in the initial assessment, and discharge deadlines don't move.

Sand filtration is often the first treatment step. It pulls suspended solids out of the water before it hits your GAC vessels or resin beds, keeps your downstream media from loading prematurely, and helps you stay within your TSS discharge limits.

Our guide, Sand Filtration for Construction Dewatering, covers how to size the right filter for your site, how to operate it without clogging your schedule, and when to pair it with additional treatment.

Summer means systems running hard and schedules that don't leave room for surprises.

Whether it's a long-term pump-and-treat system or a temporary construction dewatering setup, the compliance side of the job doesn't change: the system needs to perform, the samples need to pass, and the permit requirements need to be met every time someone shows up on-site.

Our team handles the full scope — system operation and maintenance, compliance sampling and reporting, carbon changeouts, and licensed on-site operation — so the sites we run stay running.

In June 2025, Ryan Jozwiak joined Global as a Field Service Technician. Since then, he's been in the shop and in the field — building, fixing, and keeping systems running.

That's the job. And he does it well. Welcome to year two, Ryan!
