Reducing CO2 is essential for our planet to thrive. At SCS Engineers, we’ve been helping all industries, cities, and states do just that for over 50 years. We focus solely on environmental solutions; in the industry, it’s called pure environmental, along with industry rankings that consistently rank our results in the top tiers.
Our culture is one of sharing. Our professional staff are involved in their communities and global industry associations where we speak, publish and share what works openly with you. Our newest blog series Preventing and Reducing CO2 publishes monthly, bringing you the latest papers, presentations, and case studies on reducing CO2 and targeting climate change.
We hope you find this collection of article, papers, videos, and opinion pieces helpful. The opinion pieces raise logical questions and help us create sustainable solutions rather than quick fixes that don’t stand up economically over time. We include a broader range of topics for landfills, as they diligently work toward reducing CO2 and using proven wastewater treatment options.

Upcoming presentations at the Iowa Recycling and Solid Waste Management Conference on October 4:
SCS Engineers (SCS) was retained by the Iowa Department of Natural Resources (DNR) to assist in performing research, facilitating stakeholder and subcommittee meetings, and coordinating project meetings to explore and develop potential strategies that would help transition Iowa to a sustainable materials management (SMM) system approach. The firm was also retained to perform a waste characterization study at ten landfills across Iowa during the summer of 2022, focusing on how we can best use resources to their highest and best values.
SCS Engineers will be presenting on these topics during the welcoming events on Tuesday, October 4, starting at 8:00 am, following the Iowa DNR update. Christine Collier, P.E., will discuss work with a stakeholder group and four subcommittees to identify potential SMM strategies that focus on the four primary material categories: Construction and Demolition Debris; Organics and Fibers; Plastics; and Renewable Energy Equipment.
Hannah Sperfslage and Jeff Phillips will discuss the waste characterization study evaluating the composition of municipal solid waste (MSW) generated from residential, industrial, commercial, and institutional (ICI) sectors and the visual characterization of construction and demolition debris (C&D). The results will help the DNR and solid waste planning agencies measure progress in obtaining waste reduction and recycling goals. They will be the basis for implementing new programs and policies.

The objective of this study was to evaluate a cross-section of full-scale on-site landfill treatment systems to measure changes in PFAS concentrations. Leachate samples were collected before and after treatment from 15 facilities and were evaluated for 26 PFAS, including 11 perfluoroalkyl carboxylic acids (PFCAs), 7 perfluoroalkyl sulfonic acids (PFSAs), and 8 perfluoroalkyl acid precursors (PFAA-precursors). The transformation of precursors was evaluated by the total oxidizable precursor (TOP) assay. Results showed no obvious reductions in total measured PFAS (∑26PFAS) for on-site treatment systems including ponds, aeration tanks, powdered activated carbon (PAC), and sand filtration. Among evaluated on-site treatment systems, only systems fitted with reverse osmosis (RO) showed significant reductions (98-99 %) of ∑26PFAS in the permeate. Results from the TOP assay showed that untargeted PFAA-precursors converted into targeted short-chain PFCAs increasing ∑26PFAS in oxidized samples by 30 %, on average.
Overall, the results of this study confirm the efficacy of RO systems and suggest the presence of additional precursors beyond those measured in this study. SCS is part of the technical advisory group for this collaboration of the schools in Florida and the EPA. SCS’s Liquid Management Practice is helping the group with on-site work at landfills.

From the official guidance:
SCS Engineers has a successful track record supporting communities interested in land recycling and obtaining EPA MARC Brownfields grants. Please visit our website for more information.
On Friday, September 9, SCS attended a meeting with CCLR and the State of Arizona on Land Reuse Grants. CCLR’s Ignacio Dayrit said that the guidance for EPA’s MARC Brownfields grants is expected to be released this week, opening the 60-day application period. If you plan to speak to any communities/non-profits about grant applications, now is the time to reach out to them. EPA Brownfield grants are often a significant funding source for assessing and cleaning sites with potential environmental contamination. This year, historical funding levels from the Bipartisan Infrastructure Law (BIL) mean more grants and significantly larger awards, making it a good investment to apply.
Although this information is subject to change before the guidance is finalized, here are the anticipated funding details:

Designing environmental solutions. At SCS Engineers, we value our young professionals who bring new ideas and fresh perspectives to our teams. While learning the ropes as an intern, Jared Brown now works full-time as an associate professional in our Raleigh, North Carolina office.
Jared graduated from The Pennsylvania State University State College, College of Earth and Mineral Sciences, this past May, earning his Bachelor of Science in Energy Engineering and a minor in Environmental Engineering.
Off to a fast start, he recently put to work his growing knowledge of landfill siting and landfill gas development by receiving his EIT License and Certification, a professional designation after passing the NCEES Fundamentals of Engineering (FE) exam, and an important part of the process to becoming a licensed professional engineer (P.E.).
Jared’s work is significant in addressing climate change, but not in the way he anticipated when he started his SCS internship. “During my internship, I got hooked,” says Jared.
He continues,
In my senior year, following my internship, I added multiple electives in landfill engineering and groundwater protection. My major focus at Penn State was renewable energy engineering, which SCS does, but landfill and landfill gas engineering captured my attention. It’s fulfilling to know my work significantly reduces greenhouse gas (GHG), and the work itself is interesting and challenging.
We work in teams to make the most of our different areas of expertise, but I get the chance to present my ideas and hear from my teammates while working independently. It’s not the kind of work where you do it repeatedly once you’ve created the design. Each site is unique, so I’m building on best practices and the combination of new technology and design that’s proven to work and is very effective.
Today’s modern landfills that reduce air emissions, recycle many by-products, and protect the groundwater are transformative. They use reduction, recycling, and reuse programs while turning methane into renewable energy. Advanced remote monitoring and control technology and data capture provide many efficiencies and insight to landfill operators and owners running larger and larger collections of plants and facilities on their landfills.
The trend to go larger necessitates more landfill design sophistication and master planning to recoup the growing capital investment upfront. That’s where Jared fits in!
At SCS Engineers, a leading environmental consulting and contracting firm, we bring local urgency to today’s global priorities. One hundred percent employee-owned, and with over a thousand industry leaders across 70 offices nationwide, we come to every job with a wealth of knowledge and implementation expertise—so even the most complex projects move forward with efficiency and speed. We address a full range of environmental issues for private and public entities, with a special focus on waste and greenhouse gas management. In fact, we have captured and eliminated more CO2e gasses for our clients than any other firm in the country. And with customer satisfaction scores 33 percent higher than the industry average, we’ve built a reputation for delivering on our promises.
Today’s modern landfills offset inflation and labor costs through transformative reduction, recycling, and reuse programs while turning methane into renewable energy. Advanced remote monitoring and control technology and data capture provide many efficiencies and insight to landfill operators and owners running larger and larger collections of plants and facilities on their landfills.
The trend to go larger necessitates more landfill design sophistication and master planning to recoup the growing capital investment upfront. During this month’s SCS Engineers webinar and open forum, our panel will discuss landfill design, focusing on optimizing your site layout and maximizing air space – a landfill’s golden egg.

Quinn Bernier currently chairs the SCS Engineers Young Professional Group. We recently spent time with Quinn following her return from SCS’s Environmental College, a national training forum held annually.
What is your title at SCS Engineers? Please briefly describe your responsibilities at SCS.
I’m a Project Engineer, mostly working on landfill gas system design projects, odor mitigation, and air compliance reporting. I also participate in SMM (sustainable materials management) projects, such as waste characterization studies and convenience center design.
Why did you come to work here? What attracted you to SCS?
I wanted to make a big move after graduating college, and I was looking for practical, tangible work in environmental engineering. The interview really sold me, though – everyone at the office was so welcoming and approachable. I felt like I fit in right away.
What is your favorite part of working at SCS?
Everyone says this because it’s true – the people that work here. There are so many smart, awesome people at SCS that are a pleasure to work with.
What do you feel is your greatest achievement/contribution to date?
Being on the Young Professionals Planning Committee and helping the YP Program grow the past three years while we’ve really expanded the breadth of resources we provide despite COVID – from the leadership interview series, to providing professional licensing advice, and launching a company-wide mentoring program. It’s been a privilege to be a part of serving other young professionals at the company and a lot of fun.
What was your greatest challenge, and how have you overcome it?
I’m still working on it since this largely comes with experience, but gaining confidence in my professional work and opinions. It was hard coming straight out of school to think of myself as a consultant, but I think a big help for me is remembering that I am doing a good job when I am doing the best I can for a client.
Why do you believe you have been successful?
Just putting myself out there. SCS has a very choose-your-own adventure style, and I think being willing to jump headfirst into whatever comes my way has opened a lot of doors. I also owe a lot to my peers and mentors for encouraging me to learn and grow.
You recently became a Professional Engineer (P.E.). What advice do you have for someone that is studying for the P.E. exam?
This might only apply to the P.E. Environmental, but make sure you get to know the equation manual (even the tables and charts) and practice using the search function on it. It will save a lot of time on exam day.
What are your favorite hobbies?
I play competitive soccer, keep fish, and I’m always trying new crafts. I’ve been mostly pressing flowers and sewing lately.
Tell us your favorite aspect of the YP program. What is your role as YP Chair?
The best part about the YP Program is that it’s 100% run by YPs. As the current Chair, I lead the group in our biweekly calls, send out the Program emails, and serve as a Young Professionals representative at the SCS Board Meetings twice a year.
We thank Quinn and all of our remarkable YPs for dedicating their careers to helping businesses and their communities run cleaner and safer! Join one of the most award-winning and results-oriented environmental engineering and consulting firms in the nation.

2022 Organics Management Facility of the Year.
The National Waste & Recycling Association recently named Republic Services’ Otay Compost Facility the 2022 Organics Management Facility of the Year. The Otay facility in Chula Vista, Calif., is the first fully solar-powered compost facility in the state, recycling food and yard waste from throughout the San Diego region.
The solar-powered facility opened for business last October, helping communities in San Diego County meet the requirements of California’s SB1383 law mandating the diversion of organic waste from landfills. This unique facility, designed by SCS Engineers in collaboration with Sustainable Generation, operates completely off the grid. It can process 200 tons of food and yard waste daily from Chula Vista, Carlsbad, and customers throughout the San Diego region.
The design uses renewable energy to run 100 percent of the composting operations at the site. The facility design includes technologies to speed the maturation rates and reduce excessive odors. Blowers to aerate the organic material, oxygen and temperature sensors, and advanced compost cover technology produce a high-quality product.
“Republic Services took the goals of SB 1383 further to reduce emissions of short-lived climate pollutants. They’re running a sustainable facility that enables residents, businesses, and government to easily reuse and recycle more organic materials within a smaller carbon footprint than ever expected,” says Vidhya Viswanathan, engineer and project director.
