SCS Engineers PFAS Library – Open to the Public

January 15, 2020

PFAS are a class of synthetic fluorinated chemicals used in many industrial and consumer products, including defense‐related applications and firefighting. They are persistent, found at low levels in the environment, and bio‐accumulate. Studies have shown these compounds being detected more often.

The USEPA is positioned to take serious action on PFAS in 2020, regulators in many states have already started to implement their own measures, while state and federal courts are beginning to address legal issues surrounding this emerging contaminant.

SCS Engineers has created a library of PFAS articles and resources for industry associations, local, state, and federal agencies,  and the public. This SCS blog is a list of information and educational material related to emerging contaminants. As we add new materials we will send updates via the SCS Engineers blog and social media sites.

At SCS, your privacy is assured. We encourage you to share these resources using your email or social media account; you can do this from each website page using the light blue icons shown on the left side of each resource.

1, 2, 3 – TCP: California’s Response to a Persistent Pollutant Could Help Other States

January 14, 2020

The U.S. Environmental Protection Agency (EPA) has identified 1, 2, 3 – Trichloropropane (TCP), which does not occur naturally in the environment, as an emerging chemical of concern that can threaten drinking water supplies. It states that TCP is a persistent pollutant in groundwater and has classified it as “likely to be carcinogenic to humans.” California State Water Board member Steven Moore called TCP an “insidious chemical” because it persists in the environment, sinks in water and is harmful in even tiny doses. Currently, there is no federal maximum contamination level (MCL) for TCP; however, there is a federal non-enforceable health-based screening level of 0.00075 ug/L.

Since 2012, TCP has been on the emerging Contaminant Candidate List (CCL), which is a watch list of unregulated contaminants that are known to, or anticipated to, occur in public water systems and may require regulation under the Safe Drinking Water Act (SDWA). The EPA has required, under the Unregulated Contaminant Monitoring Rule (UCMR), that large water systems test for TCP every five years with a minimum reporting level of 0.03 μg/L. This rule allows for the EPA to monitor contaminants suspected to be in drinking water that are unregulated under the SDWA. As a result of the testing, TCP has been identified across the US in drinking water sources. Currently, there is no federal maximum contamination level (MCL) for TCP; there is a federal non-enforceable health-based screening level of 0.00075 ug/L.

The author continues the paper with an examination of what TCP is and how it impacts our environment and our health. She then discusses regulatory policies and how California’s mandatory TCP standard could be a blueprint for other state water agencies currently investigating how to enhance their own drinking water protections from emerging contaminants.

Lyn covers some of the legal aspects, risks to businesses, detection, and treatment options to conclude her white paper. She also provides plenty of resources to start the journey toward sustainable treatment solutions that communities can afford.

Landfill Gas Header: Location and Benefits

January 13, 2020

SCS Advice From the Field Blog Series

 

Lessons learned from previously constructed gas collection and control systems teach solid waste professionals valuable lessons about designing for long-term survivability and reducing the maintenance cost of gas system components. The location impacts operating and maintenance costs for various components of gas collection and control systems such as condensate force main, condensate sumps,  force main for well liquids, air lines to pumps in gas wells, and gas headers long into the future. As often as possible, design the gas header in the landfill perimeter berm along with the condensate sumps. Landfill perimeter berms constructed in an engineered manner with well- compacted soils and a well-defined geometry provide a long-term cost-effective alternative to earlier designs outside the berm.

For many years, gas headers were designed and constructed outside of the landfill perimeter berm, on the landfill surface. Of course, landfill surface changes as waste elevation increases over time, resulting in many gas headers that now may be 30 feet or more below the current waste surface. Deeply buried gas headers are unreliable at best, and the operator loses access to them as soon as 20 feet of waste covers the header.

Collapsed gas headers buried deep in waste are an expensive challenge when operating a large number of gas wells connected to the gas header, and could cause serious compliance issues. Upon discovery of a collapsed buried gas header, installing a new header is a lengthy process with significant costs, not to mention the hurdles the operator will have to jump addressing noncompliance with their state agency.

The benefits of placing gas headers in the landfill perimeter are:

  • Constructing gas headers once without the need to be re-constructed again at a high cost
  • Constructing condensate sumps in line with the gas header in the landfill perimeter berm, provide technicians quick access for maintenance
  • Avoiding ground settlement around condensate sumps
  • Avoiding sagging of the gas header over time due to settlement
  • The slope of the gas header toward the condensate sumps in perimeter berms is much less than those on the landfill slope
  • There is little surcharge loading on the gas header, thereby no crushing of the pipe
  • The gas header is accessible for any additional connections if required in the future.

Since the condensate force main follows the gas header in the perimeter berm to flow to a tank or discharge point, there are additional maintenance benefits.

  • Electrical lines to electric pumps or compressed air lines to air pumps in condensate sumps are located in the landfill perimeter berm
  • Cleanouts to the condensate force main are built along the perimeter berm and accessible for maintenance
  • Flow meters, air release valves, and sampling points on the condensate force main are constructed at necessary spots along the landfill perimeter berm and easily accessible to technicians
  • Stub outs on the gas header are constructed at locations specified in the design plans along the landfill perimeter berm for connecting the gas header to vacuum lines extending up the landfill slope
  • Compressed air lines to air pumps in gas wells are constructed in the landfill perimeter berm with stub outs for extensions on to the landfill slopes and to the wells.

By continuing to design gas header construction on landfill slopes, all of the components end up on the landfill slope as well. You can imagine what type of complications the landfill operator will face since all of these components are in areas vulnerable to erosion, settlement, future filling or future construction. Additionally, any maintenance requiring digging and re-piping necessitates placing equipment on the landfill slope and disturbing the landfill slope surface for an extended period.

 

For more information about these benefits and more, please refer to the MSW Magazine article series Considerations for the Piping Network, the author, or contact SCS Engineers at service@scsengineers.com.

The Evolving Concern of PFAS at Airports – Mitigating the Risks

January 9, 2020

PFAS are also key components in aqueous film-forming foam (AFFF), which is used to fight petroleum-based fires at aviation and manufacturing facilities. For decades, AFFF containing PFAS has been used extensively at airports throughout the world to protect the safety of passengers, crew, and others. The FAA requires that commercial airports train with, calibrate equipment with, and use the best performing AFFF fire suppression systems. AFFF is required to be used at airports and must be certified to meet strict performance specifications, including those mandated by the  U.S. Department of Defense Military Specifications.

How can airports, the aviation industry, and manufacturers begin to mitigate PFAS health risks?

 

Lynleigh Love and Chris Crosby of SCS Engineers discuss the risks and issues with PFAS-based firefighting foam used at airports. The authors cover the regulatory climate,  contamination investigations,  operational and environmental management and litigation, along with alternatives to using traditional AFFF. There are some possible alternatives that can mitigate health risks in your community.

Read this article to help inform your mitigation plan and strategies to minimize risk.
