Hundreds of closed landfills in Wisconsin are required to perform groundwater monitoring and reporting. Typically, the frequency of monitoring, size of the monitoring well arrays, and the list of required parameters, was established many years ago as part of the landfill operating permit or closure plan approval. There is a potential to reduce, or terminate landfill monitoring when groundwater quality improvements are documented. WDNR guidance entitled “Reducing or Terminating Groundwater Monitoring at Solid Waste Landfills,” (PUB-WA 1013) provides instructions for requesting reductions to monitoring requirements.
Learn about new revisions to the WDNR guidance, developed with input from the WDNR’s Waste and Materials Management Study Group, which are intended to improve both the range of options for monitoring reductions and the process for requesting reductions. In addition to providing procedures for reduction in monitoring frequency, new revisions to the guidance include procedures for requesting reductions to the required number of monitoring wells and parameters. The revised guidance also provides instructions for communicating monitoring reduction requests to the WDNR review hydrogeologists.
SWANA’s new online testing platform gives members and industry professionals easy access to SWANA’s leading certification courses and exams.
The online testing platform has many benefits:
“The SWANA platform provides students the opportunity to read through the content and take their time preparing for exams; a valuable part of the learning process,” said Tracie Bills, SWANA/CRRA Zero Waste Course Instructor and Northern California Director at SCS Engineers.
The Washington D.C. Post of the Society of Military Engineers (SAME) Board of Directors selected David Hostetter for his Outstanding Contributions by a Young Civilian Member.
Hostetter says he focuses on three things in his work: using his engineering skills to make a difference in the world, serving his clients wholeheartedly, and mentoring other young professionals as he was mentored.
Hostetter mentors other young professionals by involving them in hands-on engineering projects which helps them to discover how design impacts installation and operations. They have the opportunity to ask questions and to work with senior level engineers and experienced field staff. Dave learned valuable lessons this way, and he is passing those lessons and best practices on to others.
Hostetter is now the Eastern Regional Manager of SCS RMC®, which stands for remote monitoring and control technology. Several industries use this proven technology for the simultaneous viewing, analysis, alerting, and control of equipment and systems critical to production and safe operations.
Well done, Dave!

As the real estate market improves, interest in these brownfields properties is too.
Redeveloping landfill sites can be challenging but has been successfully done in the past. Start your project by engaging the relevant agencies to negotiate the path forward for development. Specific conditions of approval should be negotiated based on prudent engineering practice and real, rather than perceived, public health and safety hazards. With the proper diligence and planning, redeveloped landfill properties can become a valuable community asset.

Odor management remains one of the most daunting tasks for any solid waste facility. Part I of Pat Sullivan’s series on odor management at solid facilities covered regulatory
requirements with two case studies detailing real-world examples of facilities battling odor issues. Part II of his series covers odor assessment, monitoring and
mitigation strategies.

High-pressure injection of liquids can be challenging in Class I wells where depths exceed 10,000 feet and extreme temperature variations occur between injection and shut-in conditions. Elevated downhole temperatures at these depths create a high-temperature differential between the injectate and annular fluid resulting in significant swings of annulus pressure and surface seal pot volumes. One-way micro tubing leaks at joints have also occurred due to these conditions.
The injectate cools the annular fluid resulting in contraction of the annular liquid and lowering of the seal pot volume, which requires the addition of fluid into the annulus. Once the wells are shut in, annular pressures rise as the annulus fluid is warmed by the native formation fluid, creating an increased pressure differential on the downhole components and increasing the seal pot volume and potentially creating high-pressure situations in the annulus. In addition to the labor-intensive operation of having to add and remove liquid from the annular space, greater downhole pressure differentials may affect long-term integrity of the injection tubing and protective casing.
Maintenance of an annulus pressure that is less than the injection pressure, similar to the operation of more shallow Class I wells, is impractical under the operating scenario for deeper wells. It also creates the potential for fluid migration from the tubing into the annular space in the event of a leak.
Monte Markley, P.G., and Stephanie Hill will present this and more at the 2018 Underground Injection Control (UIC) Conference. The presentation will focus on the design and implementation of an innovative high-pressure annulus monitoring system that mitigates the presence of micro tubing leaks in joints, and pressure and temperature swings of the annulus.
Marc Rogoff sees unprecedented factors in play as “The Perfect Storm”—the banning of solid waste materials and imposing an almost unreachable contamination standard on bales entering China.

Governor Pete Ricketts recently re-appointed Mike Miller of SCS Engineers to the Governor’s Council to Keep Nebraska Beautiful for an additional term until December 31, 2020. In a letter dated December 19, 2017, the Governor expressed his gratitude for Mike’s valuable input and service to the citizens of the state of Nebraska.
Congratulations Mike. We’re proud of you!
Som Kundral is a Project Manager with the Miami office. He is currently managing a 500-acre C&D landfill redevelopment project involving multiple engineering disciplines. Som serves clients in the region by providing design and construction oversight of groundwater remediation and landfill gas management systems. He says redevelopment on old landfills pose interesting environmental challenges and can be complex given the heavy involvement of regulatory agencies.
Som was born in 1983 in India, raised in Karnataka, a state in southwest India on the coast of the Arabian Sea. He has two younger brothers, both of whom work in Information Technology. His parents are retired and live in India. He grew up in a typical middle-class family with an emphasis on tradition and culture, where one is taught to respect and obey elders and to protect the young.
As a child, he was curious about how things work and admits to destroying numerous gadgets attempting to reveal their secrets – so engineering was a natural career choice. His father is a Civil Engineer who influenced Som to get a Civil Engineering degree instead of a Computer Science degree. Som has a Bachelor’s degree in Civil Engineering and came to Miami in August 2010, to earn a Masters of Environmental Engineering. While at school, he says he fell in love with the place, the people, and the culture.
Som’s wife, also an engineer, moved from Houston after their wedding in 2012. They enjoy gardening, greenery, and farms. He also collects watches and gadgets. While enamored with motorcycles, once belonging to a biking group as an undergrad, he no longer bikes out of respect for his wife and says he misses it.
Som aspires to become a leader in the industry and wants to grow with SCS Engineers. Som’s mentor is SCS Vice President and Southeast Region Office Director Bob Speed, who states,
I’ve worked with Som for several years. Som accepts tasks regardless of the difficulty and completes each promptly. Our projects usually have numerous stakeholders; Som keeps them informed, so good communications play an important role in keeping our work on-task. I would describe Som as ‘humble, hungry and smart; he truly is an ideal team player for our clients and SCS.
Som is an enthusiastic member of the SCS team. We appreciate his contributions supporting clientele, enhancing our technical reputation, and contributing to our company culture of industry involvement.
Many state and provincial governments have begun promulgating policies and regulations that target the recycling of organics prompting local solid waste agencies to develop advanced municipal curbside collection programs.
A key question for local solid waste agencies to answer is, what types of organic wastes will be targeted for collection and processing? SCS Engineers covers this and other facets to consider as part of your plan, such as:
