The Professional Environmental Management Association (PEMA) named Paola Gomez-Birenbaum, PG, Apex’s Senior Geologist, as director-at-large their Southern California board of directors. In this role, Paola will help the environmental trade association’s directors and committees achieve their goals to​ provide education, interaction, and professional skill development to PEMA’s members and professionals both within and intersecting the environmental industry.

Paola, and her Signal Hill colleague Ben McVeigh (both pictured) attended a recent PEMA-sponsored holiday fundraiser tocollect donations for non-profit organizations such as Toys4Tots. Charities sponsored by PEMA—St. Vincent Meal-on-Wheels and the YMCA Community Services—were presented with checks (totaling $22,500) for proceeds raised by PEMA’s various committees at their annual events.

Apex’s Ben McVeigh stated, “PEMA is an impressive organization and this was a great event. This year’s charitable donations will help deliver meals to the elderly and help the YMCA provide community services. It was an honor to witness the groups’ sincere appreciation and hear how the funds will be used.”

​After the event, representing Apex, Paola attended her first board meeting. Sharing her thoughts, she added, “PEMA has had a long relationship with the St. Vincent Meals-on-Wheels. A St. Vincent nun who had worked with the PEMA board for several years passed away this year and I noticed a few board members were wearing angel pins she had given them during past holiday events. Clearly it is relationship they valued and a cause that is special to them. I enjoyed seeing how passionate they were about the charities they support."

Regarding joining the PEMA board, Paola said she’d been looking to make a contribution in the environmental field with an organization that would positively impact her work at Apex with fellow colleagues, clients, and regulators. "PEMA does a good job of combining the very technical aspect of our industry with the practical side of the work we do. I’m looking forward to building my network and becoming involved with the various seminars and fundraising PEMA has started planning for the new year."

Subsurface Investigations. Superlative Work.

Conducting intensive contaminant investigations—something our talented teams do daily—is hard work. Now picture that same work in a busy, industrial section of downtown Los Angeles with narrow streets that can barely fit the necessary drill rigs. Factor in multiple utilities and a highly-pressurized gas line to contend with. Pepper in some extra maneuvering to ensure that all the property tenants’ businesses are as minimally impacted as possible. And add the challenges of helping the property stakeholders understand the application of the Department of Toxic Substances Control (DTSC) consent order that prompted the project in the first place. That’s what our Apex team is impressively addressing as they finish conducting an investigation of a former metal plating site riddled with tetrachloroethene (PCE) from decades of degreasing operations.

Our team’s investigation—across the site’s former plating areas, a wastewater treatment system, metal coating operations, chemical storage areas, linear floor drains, and a soak cleaner pit—assesses the extent of volatile organic compounds (VOCs) in the soil gas and groundwater beneath the site, and as necessary, in the public right-away. This includes drilling up to seven borings, collecting soil samples, installing groundwater monitoring wells, installing multi-depth soil gas probes, and collecting soil gas and groundwater samples. Our team has recommended soil vapor extraction (SVE) as the remedial approach and we will be proceeding with that as another adjunct project stemming from this one. SVE, an approach our team is adept at using, involves drilling extraction wells into contaminated soil and connecting a blower or vacuum pump to pull the vapors through the soil and up the well to the ground surface for treatment. Apex will be installing as many as four additional SVE wells to capture VOC contamination in soil more than 160 feet deep.

We’re proud to do our part. Just one more way we’re helping to make a difference in our communities.

Apex’s Carmen Owens Listed Among Women of Vision

Recognized for Industry Leadership and Community Involvement

ROCKVILLE, MD—August 22, 2018—Apex Companies, LLC—a leading water resources, environmental services, and industrial hygiene firm—announced today that Apex Senior Engineer Carmen Owens has been named by the Daily Journal of Commerce (DJC) as one of their “2018 Women of Vision.” Each year, the publication recognizes select women for their valuable contributions to the building industry in Oregon and Southwest Washington. The award specifically honors those, such as Carmen, who have exhibited outstanding industry leadership and community involvement with a solid commitment to diversity, inclusion, and mentorship.

“Carmen simply shines, personally and professionally,” stated Apex Division Manager Adam Reese. “Whether she’s managing environmental remediation projects, overseeing asbestos removals, securing the habitats of endangered species, or promoting our company’s sustainability program, she always adds tremendous value. Protecting and preserving our environment is important to her. But it’s her positivity and her ability to lead with kindness and inspiration that enables her to truly make a difference. We’re excited that, as a DJC award recipient, she’s receiving the recognition she most certainly deserves.”

This year’s DJC honorees will be recognized at an award ceremony on October 18, 2018 at the Portland Marriott Downtown Waterfront hotel. For more information about the award or reception, please click here.

With a MS degree in Environmental Engineering from the University of Iowa, Carmen has eight years of environmental consulting experience providing a wide range of services including site assessments, due diligence, hazardous building materials remediation, feasibility studies, wetland delineation and mitigation, permitting, and source control. Recently, her work has focused on contaminated sediment while managing the assessment and remediation of multiple waterways within the Portland area. Her community work is equally impressive. As one of the leaders of Apex’s sustainability program, she helped the Portland office go ‘green,’ demonstrating our company’s commitment to environmental and social responsibility. Carmen also serves as a mentor within the Women in the Environment professional group, expanding its membership to include representatives from government agencies, the non-profit sector, and other industries; as a coordinator at the Columbia Slough Watershed Council School, teaching classes about sustainability, cleanup, and development; and as a volunteer with Friends of Trees.

Oil and Gas Reclamation. Real Results.

Surface reclamation is about to get a lot easier thanks to Apex.

Oil and gas (O&G) operators must adhere to strict surface reclamation requirements enforced by federal and state regulatory agencies. That means they must restore the natural landform, vegetation, hydrology, and wildlife habitats to the same condition the land was in before they disturbed it for their operations. That is tough enough for many O&G companies but for those in Colorado, it’s particularly dicey. The Colorado Oil and Gas Conservation Commission adds what the Bureau of Land Management calls “the most stringent state standards in the country.” Factor in the O&G industry’s ever-shifting regulatory and consulting teams, and it becomes even more complex. All this uncertainty translates into increased costs and compliance delays, which in turn keeps operating capital tied up in bonds regulatory agencies won’t return until the surface reclamation is complete.

Thankfully, for our client, with over 700 sites currently requiring surface reclamation, our program manager stepped in with an innovative way to use our proprietary environmental management information system, ARTEMISSM, to proactively solve their challenges.

Our team knew that using ARTEMIS would keep our client’s regulatory balls in the air. While that alone is nothing new, as ARTEMIS has helped many satisfied O&G clients do the same, our team’s concept—to encapsulate the entire reclamation process in ARTEMIS—is. Apex shared this vision with our client and they contracted us to make it happen. ARTEMIS will track and capture each facet of the surface reclamation process including stormwater, invasive species, soil stabilization, erosion control, hazardous waste removal, flowline capping, pit closing, land grading, and vegetation planting. Once complete, our client will gain a clear understanding of what has been done, what’s in progress, and what needs to be tackled in the future. Similarly, Apex will be able to seamlessly connect our project managers across every service line we provide for the client, digitally spurring the next phase of work. And, in addition to helping our client with its current site portfolio, the solution can also be readily deployed for other O&G clients throughout the US.
