Demonstrating the Value of Landfill Gas Information Management

SCSeTools® – Developed by Landfill Gas Practitioners for Landfill Owners and Operators

The Birth of LFG Data Tracking

In the early 2000s tracking landfill gas data at facilities was anything but uniform, organized, or secure. The industry was using various methods to track data on paper forms and logbooks, then transferring it by hand into spreadsheets. Some of us used desktop database applications, but as the saying goes, necessity is the mother of invention.

From an SCS employee’s idea for demonstrating how to use landfill gas monitoring data to analyze and pinpoint system corrections, SCS DataServices® was born. In the span of several months, a team of SCS’s landfill engineers, field technicians, and technology gurus worked with client-needs to create a concept application visualizing collected landfill data on maps. Our staff field-tested it with good results, and SCS Field Services began using the application to visualize issues with wellfields that aren’t readily apparent when looking at spreadsheets.

A large SCS landfill client had seen our field staff using DataServices, asked if SCS would consider providing them with access to the application on a subscription basis. Our team adapted DataServices, added features, and continued improvements tailored for the client’s use.

As soon as secure data transfer became feasible, SCS moved to an Internet-based solution for our landfill gas practitioners. The platform called SCSeTools® holds the data collected by SCS DataServices®.

Applications and features roll out as we continually update and upgrade, incorporating ideas and improvements from our users and staff along the way. DataServices is addressing the landfill gas management needs of over 600 landfills across the US and Canada in 2021.

The keys to success follow our mission and values of maintaining close communications with our clients, field staff, engineers, and eTools support staff (all landfill gas practitioners), with the help of software engineers. Technology companies are not up at night thinking about landfill operations, but we are.

We introduce our SCS eTools landfill technology capabilities and a few of the creative and talented SCSers behind the technology in the next segment. Our speakers walk you through demonstrations of how over one-third of the landfill owners and operators in North America are increasing efficiencies using SCS eTools.

 

Visualizing Landfill Challenges – Shortcuts to Keeping Your Wellfield in Balance

DataServices shows the entire wellfield for any monitored parameters and zooms in on troublesome areas or wells. Results can be as simple or detailed as the landfill owners’ environmental and business needs dictate. The detailed examples here illustrate how graphs, maps, and charts help keep the wellfield in balance. We link each challenge to the description of a video demonstration.

In balance means extracting more gas for renewable energy, preventing odors and methane migration, keeps subsurface and surface conditions and workers safe. The information can help diagnose equipment conditions before they become costly, maintain regulatory compliance, and support cost estimates if the landfill is expanding or more infrastructure investment or equipment is needed.

Looking at vacuum distribution across a gas collection system – Select the system pressure map, which highlights vacuum distribution across the wellfield to show the wells with good (expected) vacuum, pressure drop over distance, and any wells unexpectantly losing vacuum.  Zooming in and changing the vacuum ranges further enhances where to assign staff to troubleshoot any identified issues.

Using a methane distribution map shows whether the wells are tuned to where the landfill owner wants them. Wells may be identified below the targeted range, indicating slight over pulling; a technician can use this map to identify such issues and quickly check the identified wells. Wells identified above the desired methane tuning range indicate wells not collecting enough gas, which has consequences. These wells can be the source of odors, leachate seeps, possible lateral migration to an out of waste probe. Not sending enough fuel to a power plant or atmospheric releases can affect surface emissions monitoring.

Managing liquids – Changing waste streams and more rainfall in certain areas of the country complicates liquids management. DataServices visualizes the impacts of liquids on wells and helps landfill owners better manage a proper liquids removal program.  The program will let them know how many pumps to budget for and, over time, where to relocate well dewatering pumps so that they are most efficient at removing liquids from landfills.

High-BTU Gas Plants –Filter maps help users locate wells contributing to gas dilution into renewable energy plants. It can help create punch lists for landfill staff to investigate, troubleshoot and tune. As wellfield technicians make corrections, they show on the map in real-time.

Temperature and subsurface oxidation events – Some call the condition subsurface fires, but this is a serious issue for landfills. Over-pulling wells, damaged infrastructure, and other conditions can cause oxidation events. Using a combination of temperature Parameter Maps to review wellhead temperature distribution and a Points Chart feature provides a deeper dive into the data. It provides more insight into which well or wells may be contributing to the high-temperature issues.

Locating a specific well – That’s not so easy when hundreds of wells surround you and at larger landfills. DataServices had built-in filter features to identify a single monitoring point on a wellfield map easily.

Customizing for compliance, best practices, and rules – DataServices allows monitoring points across a single site to have customized rules for each monitoring point. Rules can be for regulatory purposes, standard operating procedures, best management practices, and even site-specific preferences or any combination thereof. It is efficient to customize rule application to landfills and collection points – meaning wells, probes or ports, horizontal collectors. This customization capability helps organize and confirm regulatory compliance. It is especially salient with the 2021 EPA and state compliance changes for a single landfill or an organization with hundreds of landfills.

MobileForms – Inspection forms, blower flare station monitoring forms, load tracking from municipalities, incoming hazardous waste tracking, MRF bale counts are examples of paperless entry available. The data feeds directly from mobile phones to the supervisor and into the maintenance department, so staff can start cataloging and looking at what’s going on in real-time at several types of facilities. It’s available for regulators and inspections and helps reduce staff hours tabulating and centralizing the information.  Any information historically captured on a form or log attached to a clipboard can now be captured and stored electronically.  From there, it can be recovered and produced as a PDF export file or data from the forms used to trend data and help make informed operational decisions.

MobileTools – DataServices in a condensed format suitable for mobile devices. Field staff use MobileTools to save time formerly used to return to the office, transfer/transcribe the collected data and upload it to a supervisor for quality checks before storage.  Technicians can now recall the last 20 readings for any given well and review trend graphs on their phones or tablets while standing adjacent to the well they have questions about and need to access the data.  MobileTools also allows them to upload field data such as liquid level readings while the data is being collected.  The information instantly populates into DataServices and is available for review by others on the project team.

The most valuable tools are in development now for release in 2022. ARC GIS integration developed under SCS RMC® will further enhance DataServices with even better visualization and location capabilities and provide enhanced features such as allowing landfill owners to see their well as-built information and view subsurface information about their wells.

Hydrogen Sulfide Balancing Act – Act Fast, Think Long-Term

October 11, 2021

Sim emphasizes that operators should not be surprised or act too quickly when they turn on the gas extraction system and see spikes in H2S concentrations. He explains why below…

 

Hydrogen sulfide (H2S) levels are creeping up at some landfills, especially those that take C&D waste; some are seeing concentrations in the thousands to 30,000 parts per million (up from about 20 to 40 ppm ten years ago). And even at very low concentrations, H2S can be problematic.

Material Recovery Facility residuals, which typically contain significant amounts of pulverized drywall, are high in gypsum and sulfate. Once broken down, residuals become a high-surface-area material, leaching into and spreading through waste. When reacting with water and organics, it can potentially generate H2S. With a drive to divert more C&D debris, and regulations tightening around H2S, operators’ jobs get harder as they work to stave off emissions from this corrosive, flammable compound notorious for its “rotten egg” odor.

When building out their gas collection systems, controlling H2S becomes even more daunting. Sol Sim, an SCS Engineers Vice President, explains, “We see H2S concentrations jump when we expand landfill gas collection systems, often in cells that contain C&D residual screening materials. The gas was there all along but sequestered. Now it’s coming out of the ground, and the onset of issues can spike suddenly.”

SCS DataServices Hydrogen Sulfide Range Map is useful for quickly locating potential treatment locations by visualizing the big picture and zooming in on individual wells or well clusters to assign staff.

When spikes come on quickly, Sim’s team implements turnkey interim treatment approaches. They start by identifying the gas collection wells with the highest contributors and act fast to get them into compliance.

SCS teams take a two-pronged approach by stepping back and thinking about the big picture while taking action. It provides a major advantage to moving too quickly.

The more data, the better. Your engineers can simulate treatment with various media to assess the impact on flare inlet concentrations. And knowing potential impact at the flare is critical; it’s the compliance point where regulators measure sulfur dioxide (SO2) emissions.

SO2 can’t be controlled through combustion, so removing H2S from waste before sending gas to the flare is essential. Sim thinks back to problems he’s investigated for clients who had SO2 sneak up on them, causing failed sulfur dioxide emissions testing.

The proactive measure of identifying problematic gas wells and treating them is key to staying in compliance. And Sim often finds clients using interim solutions as long as they can. He has seen them work well for up to five years but they don’t resolve operators’ long-term issues, which will become more challenging as our waste streams continue to change or as landfills continue to accept more and more C&D materials.

“We solve immediate issues, address the impact of incoming materials several years in advance, and begin planning for the next 20 years. It’s how we determine strategies to minimize emissions and improve efficiencies into the future with consideration to needs as landfilling and recycling evolve.”

“We’re going to investigate thoroughly to pinpoint and understand the cause, but we do take immediate action in the interim. As part of the solution, we’ll develop an informed strategy to prevent issues well into the future,” he says.

For the longer haul, it takes time to get building permits. Coming up with permanent engineering designs and treatments requires a lot of troubleshooting and research. Even once engineers identify a lasting fix, it takes time to manufacture and install larger vessels and other infrastructure.

 

But they don’t wait for all these pieces to come together to act.

The priority is getting operators in compliance right away or taking down emissions if they are on the verge of noncompliance. As work begins, operators can breathe a little easier knowing they have time to figure out how to allocate resources and funds to implement a more permanent strategy.

“We’ve seen where data we’ve gathered while working on the immediate problem enables our clients to gain insight to make good decisions around rightsizing their infrastructure moving forward,” Sim says.

 

Watch and study while addressing the immediate problem.

Sim emphasizes that operators should not be surprised or act too quickly when they turn on the gas extraction system and see spikes in H2S concentrations.  There is usually an initial spike from a new high H2S producing area at the onset of gas collection.  He has seen operators abruptly stop extracting, which can lead to odors or other compliance issues.

“When you put in a treatment system, you can take out the initial surge in H2S to allow time for the concentrations to level out. It’s important to allow that window for initial surges to run their course to understand the problem better. Otherwise, you could over-design your system around a short-term event,” Sim advises.

He points to a real-life scenario: a site that skipped the interim step of starting with a less expensive initial solution. Once they started drawing on the gas, they realized the problem was not as substantial as originally thought, and they didn’t need a multi-million-dollar system in the end.

 

A balancing act.

“Imagine H2S generation as an expanding balloon; if you pop it, air rushes out fast [akin to when you first pull gas from the ground]. That concentration level scares people. But if you react by shutting off extraction points, your balloon will continue to expand and eventually create odor problems. The goal is to extract the gas and H2S at the rate it is being generated, so it’s a balancing act, where expertise and technology both play key roles,” Sim says.

Early work typically begins by identifying wells that are the highest contributors and concentrating efforts there. It’s a complex process as sites can have fifty to thousands of collection points. Having the historical data and saving the data to watch the trend makes identifying and analyzing specific wells or clusters much more efficient.

Successfully attacking those high offenders requires an understanding of flow and concentrations.  After locating the problem area, Sim takes samples using Dräger tubes at strategic points throughout individual wells and headers to identify concentrations. Gas well monitoring and the corresponding flow data will tell you if you’ve taken emissions down sufficiently.

SCS Webinar: Using GIS Technology on Landfills, Facilities, and Development Projects

June 10, 2021

Recorded Live Thursday, June 10 at 2:00 pm ET

 

Watch Using GIS Technology on Landfills, Facilities, and Development Projects Now

 

GIS improves operational efficiency at waste facilities, landfills and helps keep development projects on schedule. GIS technology transforms volumes of collected data into maps and easy-to-understand dashboards – making staff assignments and decisions more precise and timely.

Our panelists use case studies to demonstrate how they use this proven technology in new ways to improve forensic, diagnostic, and planning activities. Join us to learn how your operation may also leverage GIS to address these challenges:

Landfills: Operators make diagnostic and forensic use of GIS to address maintenance tasks faster. We’ll cover modeling 3D wells and liquid level data, showing how GIS embedded dashboards and infographics pinpoint exactly where to assign staff. At the same time, supervisors monitor completed assignments seeing real-time results and what still needs attention.

Siting Facilities: Decision-makers use multi-criteria decision analysis incorporated into a geographic information system to account for relevant technical data, environmental, social, and economic factors during the site selection of a waste transfer station. The resulting maps and infographics are useful at public meetings too.

Property Development: Time is money on development projects. Environmental engineers use GIS to more accurately pinpoint potential contamination sources, conduct site assessments, strategize remediation solutions, and see sampling results weeks faster. Infographics and dashboards show if and exactly where to continue sampling without waiting weeks or months for reports.

Melissa Russo Thirsts for Knowledge and Enjoys Competition

June 3, 2021

 

When Melissa Russo’s boss Phil Carrillo told her he thought she should get her drone pilot license, she thought he was kidding. At the time, she worked on SCS’s Remote Control (RMC) team; selling drone services was a part of her job, but she had not thought of flying these unmanned vehicles herself.

Her thirst for competition kicked in when he turned the proposition into a bet. He was going after his pilot license himself; she bet she’d beat his score. They finished in a dead heat, but what started as friendly rivalry ended up bringing a new dimension to Russo’s job— a job that continues to expand in breadth as new opportunities turn up.

Today she not only flies, sells drone services, and teaches others how to sell and fly, but she’s helped bring geographical information systems (GIS) into RMC’s portfolio. How these technologies fit together is RMC remotely collects data from drones and different landfill systems. Then the GIS translates that data into maps, capturing a visual picture of how clients’ facilities’ systems are performing. The GIS piece is one of the latest chapters in the story of Russo’s evolving role (more to come on that).

 

Piloting is what especially gets her juices going.

Drone monitoring pipelines.

“I love working with my team, supporting them in what they do. But when it comes to drones, I like the hands-on experience of flying myself more than telling other people how to do it.”

She controls these small aircraft from a device on the ground, sharply focused on her surroundings while keeping the drone in her sight at all times.

“You have to make sure there are no manned vehicles around; they have the right of way. And there’s a lot of continuous movement on landfills. You’re constantly aware of your surroundings. Is a truck coming? Am I in line with where dumping is going on?”

 

Flying drones takes muscle and mechanical aptitude.

The drone and case can weigh 45 pounds. And there are a lot of moving parts to assemble and calibrate.

Sometimes it’s manual work, pointing and rotating a remote controller to send a radio signal to tell the drone what to do. But more often, she pilots automated flights that she maps in advance and uploads the flight path specs into software that interfaces with the drone.

“When I’m flying drones, I can access areas where if I had boots on the ground, I couldn’t. I can go and explore just about anywhere, similar to when I dream— only it’s real,” she says.

With any task, she’s laser-focused, concentrating on one part of the picture at a time to grasp the details. She steps back and uses critical thinking, accumulated knowledge, and imagination to take on what’s before her.

 

The innovation process

“We’re pretty lucky with our timing; new and proven technologies are emerging quickly. I’m one of many SCSers with a deep knowledge of technology and practical experience in the solid waste industry. Together, we can make a difference because we understand the business and operational challenges very well. When I need an expert in another industry, I just reach out to a colleague. The learning process never ends, and each project helps me and my team constantly find better answers.

“My boss is more of a big-picture person; his ideas are huge and amazing. He comes to me with new ideas, and I figure out how to make them work and implement them,” Russo says.

She points to his idea to use proven GIS technology within RMC. She was already using GIS to map methane data, process topographic maps, and stockpile calculations. For instance, she integrates methane values into the GIS and overlaps them with imagery so her clients can zoom in on one well or get a large-scale view of the overall health of the gas collection system. But integrating GIS in new ways to incorporate multiple landfill systems would solve some expensive problems and, better yet, prevent even more expensive mitigation and repairs.

 

Expanding GIS applications to illustrate multiple landfill systems

Examining multiple wellfield conditions, then zooming in on specific well metrics makes assigning field staff and technicians more efficient. See liquid levels, and many other conditions well by well, or in “hot” areas for LFG diagnosis.

“I know drones and how to process drone data. But now that we are expanding applications, I add more layers of landfill data, such as liquids, soil, the gas collection and control system (GCCS), SCADA, and surface emissions, to bring them into the RMC GIS platform. My colleagues are demonstrating these technologies at the SCS June Client Webinar.”

“I created a team of hand-picked SCS staff with both GIS and waste management backgrounds (and a whole lot of drive) to make the vision come to life,” she says. “That’s how we innovate, tight teams with access to nationwide expertise.”

Within six months of the project’s genesis, Russo and her team had integrated gas and liquid collection systems, other landfill systems, and asset management into the RMC GIS platform. She and her team now sell these applications nationwide.

 

Russo’s come a long way since joining SCS at age 21

In her mind, she grew up at the company. Before coming on board, she managed a shop in Manhattan Beach, California, while she began thinking about what to do next.

“I learned a lot about business and people. It was a stepping-stone – I discovered how to earn trust, build rapport, and sell. But in time, I decided I wanted a more professional job,” she recalls.

She went to work for a real estate company managing the SCS Engineers Long Beach office, where she would soon take an entry-level Accounts Payable position in SCS Field Services.

In time, she transitioned to the Health and Safety group, assisting in creating training material and managing truck fleets. Soon she was managing assets, among other firsts for her. By this point, she had developed enough software, accounting, and other administrative skills to step up fast.

Part of the job was keeping up with vehicle maintenance, so she often spoke with field staff. Many of them she already knew from her days working in the accounting department.

 

Growing with her SCS colleagues

“When I was in my first administrative roles, I supported many colleagues who were field techs or supervisors; they are project managers now. It feels as though we’ve grown up together, and we know and trust each other. We collaborate well and know that when we bring projects to each other that we will take care of each other,” Russo says.

She especially likes the RMC concept because remote control and automation enable her, her clients, and her team to work smarter, not harder because they leverage the technology to work for them.

“That means we can usually work from anywhere, giving all of us more time for family, friends, or allocating the time saved towards other needed to-dos. I’m up at five a.m. and, at times, may not finish work until nine at night. Somehow, us working women find the balance in between meetings, writing proposals, and answering emails; I have lunch with my two boys or take them to a park,” she says.

Bambi Lance, a veteran SCSer and her mother, works in the same business unit as Melissa does. “Mom’s been here for 16 years, and it’s interesting to have her perspective not only as my mom but as someone who knows SCS. She knows my department, and she knows me. She sees what I am doing and she along with management encourage me to do more and believe in myself.”

Russo reflects again on the concept of stepping-stones on the way to knowledge and maturity. I’m competitive and take on challenges, which has been a driving force in all I do today. It’s helped me take a personal inventory of how I am now versus the young Melissa,” she says.

She uses it to gauge her direction. And she uses it to connect to her staff. “I try to help them see you can turn almost any experience, into a positive. I want my team to see we are all learning and growing. They can, as I can, comfortably bring new ideas to the group and company, which often turn into new ways to help clients.”

She circles back to her decision to fly drones, explaining how it aligns with her career path from her first steps to today. “Becoming a pilot was a natural fit because it’s a new challenge. The craving to take on new tasks is how I grew from an accounting administrator to a project coordinator up to a business manager. It’s wanting to expand my knowledge, tackle new feats, and accomplish what I was not sure I could do. I like the challenge.”
