On August 17, 2023, the United States Environmental Protection Agency (EPA) released the first of twelve datasets (representing approximately 7% of the total data that it plans to collect) on 29 polyfluoroalkyl substances (PFAS) and lithium (an alkali metal) in our nation’s drinking water. This sampling will continue through 2026, and is the latest action delivering on the EPA PFAS Strategic Roadmap, which dictates that PFAS (an emerging contaminant pending regulations under CERCLA) requires a multi-agency approach and specific actionable steps to assess risks to human and environmental health better, hold polluters accountable, and identify the extent of the problem.
Monitoring PFAS and lithium is currently under the fifth Unregulated Contaminant Monitoring Rule (UCMR 5). The Safe Drinking Water Act (SDWA) requires that the EPA issue a list of unregulated but potentially harmful contaminants every five years and devise a protocol for monitoring those contaminants in public water systems (PWSs).
The current UCMR 5 regulatory framework allows for collecting PFAS and lithium data throughout the United States. It aims to create science-based decision-making regarding how to address these chemicals best. Results, which will get quarterly updates, can be reviewed by the public on the EPA’s National Contaminant Occurrence Database.
While there is not currently a final drinking water standard in place for PFAS, EPA has already issued health advisories for four PFAS compounds, and two of them – perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) – have also been proposed for entry as hazardous substances under CERCLA, as of March 2023. The timeline for the final rule on PFAS CERCLA designation is now February 2024. Landfills and other passive receivers are seeking relief from CERCLA contribution litigation prior to designating PFAS as hazardous substances, as they have no control over the use and disposal of hundreds of thousands of products containing PFOA and PFOS.
This first set of data does appear to raise some red flags, though it is not uniformly indicative of widespread contamination. In Missouri, for example, 1,923 distinct water samples were obtained from 22 different PWSs (from a mix of wells and treatment plants) in communities throughout the state. Of these samples, 23 are scattered between 11 facilities containing lithium at concentrations in excess of the laboratory Method Reporting Limit (MRL) of 9 micrograms per liter (µg/L), some by many orders of magnitude. Only two PFAS compounds (PFOS and PFHxS) are above their MRLs (0.004 µg/L and 0.003 µg/L, respectively), both from the North Rodeo Well of the Camdenton PWS.
This data will ultimately be immensely useful for public sector officials trying to make policy decisions regarding PFAS and lithium management, fine-tuning community engagement/education efforts, and for private sector industries seeking to get a handle on potential liabilities. SCS Engineers and other qualified environmental firms are poised to be essential partners to national leaders in identifying and remedying emerging contaminants such as PFAS. Many technologies proven to work on a large scale are available, with more promising technologies on the horizon.

In her paper, Utilizing Multiphase Flow Modeling to Estimate CO2 Solution Storage Efficiency and Sequestration Project Size, author Kacey Garber discusses how developing an understanding of CO2 storage efficiency and CO2 capacity estimates for a Carbon Capture and Storage (CCS) project will help you properly scope your project location and therefore maximize the benefits CCS has to offer.
The storage component of a CCS project requires a Class VI Underground Injection Control permit to inject supercritical CO2. These permits require multiphase flow modeling to delineate both the extent of the injected supercritical CO2 and areas that exceed a critical pressure threshold as a result of injection. SCS has found this modeling to also be valuable during project scoping to provide a sense of the total CO2 storage capacity for a given project.
Kacey walks through a case study that utilized a multiphase flow model to investigate what operational parameters would lead to the most efficient use of pore space for a CCS project in development. This included examining the effects of different injection rates, durations, and locations and investigating multi-injection well scenarios. This case study ultimately shows that a multiphase flow model will help you meet the requirements for your Class VI injection well permit application; it will also help you right-size your CCS project during the planning phase. Incorporating project-specific considerations into the model will help you identify operational conditions ideal for maximizing CO2 storage efficiency.

Capturing carbon and injecting it into a carbon sequestration well, also called a Class VI Well, is an EPA-approved technology. Manufacturers and industries are considering using carbon sequestration to reduce greenhouse gas emissions (CO2). Often, the public is concerned that carbon injection wells could contaminate underground drinking water — a legitimate concern, given today’s headlines. In this environmental engineering blog, we’ll describe the two ways underground drinking water could be contaminated and how to prevent it.
Contamination can occur if the CO2 can migrate up the well bore into the aquifer anytime after injection. The second instance is if pressure forces the brine from the injection zone into the aquifer.
Environmental engineering teams, which include professional geologists, hydrogeologists, and geoscience experts, take steps and provide well-operators guidance to protect drinking water sources, including calculating the Area of Review (AOR) around the injection well and computational modeling to understand how the pressures can build up during injection to create unsafe conditions.
Armed with expert knowledge and more modeling accuracy, operators can prevent contamination, extend the life of carbon sequestration wells, and address public concerns.
Dr. Charles Hostetler explains in the SCS educational video how accurately calculating the AOR and understanding critical pressure work together so companies can confidently use carbon capture and sequestration to reduce greenhouse gas emissions safely.

This year’s National Brownfields Conference in Detroit, Michigan, was notable. The evening before the conference began, the United States Environmental Protection Agency (USEPA) hosted an ‘Environmental Justice’ caucus in which over 150 people from both the public and private sectors came together to learn more about what Environmental Justice is and how it informs our work in economic development efforts.
USEPA defines Environmental Justice (often called ‘EJ’) as “the fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income, with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies.” We’ll achieve this goal when everyone enjoys the same degree of protection from environmental and health hazards and equal access to the decision-making process to have a healthy environment to live, learn, and work.
Distilled to its core, EJ is a call to action for all individuals and entities engaged in helping sustain and grow their communities. It posits that multiple demographics (including but not limited to people of color, inhabitants of rural areas, and people with less access to education and well-paying jobs) are disproportionately subject to harmful impacts from exposure to toxins and pollutants. Accordingly, it is incumbent upon those engaged with those populations to pay heed to find ways to mitigate or reduce those exposures.
EPA formally established the Office of Environmental Justice and External Civil Rights on October 6, 2022, and since that time, has engaged over 200 people across the agency to perform tasks specifically addressing EJ, including “processing grant applications from communities with environmental justice concerns, reaching out to residents to understand their concerns, and enforcing civil rights.” The EPA also established the Environmental Justice Thriving Communities Grantmaking (EJ TCGM) program in direct response to two Executive Orders issued by the Biden administration (EO 14008 and 13985) and will soon award ~$550 million to 11 distinct entities (which must be community-based nonprofits or partnerships between community-based nonprofits and either Tribal government or institutions of higher education) to spearhead more inclusive and easily accessible resources/support for communities seeking EPA funding to address EJ concerns.
EPA also established 16 technical assistance centers across the nation under the EJ Thriving Communities Technical Assistance Centers Program (EJ TCTAC), aimed at “providing technical assistance, training, and related support to communities with environmental justice concerns and their partners. The services provided will include training and assistance on writing grant proposals, navigating federal systems such as Grants.gov and SAM.gov, effectively managing grant funds, community engagement, meeting facilitation, and translation and interpretation services for limited English-speaking participants.”
Furthermore, the 2022 Inflation Reduction Act created the Environmental and Climate Justice Block Grant program in section 138 of the Clean Air Act (CAA). It provided EPA with $2.8 billion in grant funding for the program for projects to benefit communities with environmental justice concerns.
All told billions of dollars are currently available to communities that seek to spur environmental cleanup and revitalization efforts. SCS specializes in helping communities connect with this funding (even providing in-house Brownfields grant writing services) and has a proven track record of forming successful partnerships which result in timely and meaningful rejuvenation projects.
Two of the projects SCS teamed on this past year are awardees of the EPA’s prestigious 2023 Phoenix Award. The first of such projects, performed in EPA Region 6, involved the restoration of the historic First National Bank Building in downtown Oklahoma City, OK. This project created a mixed-use space, including apartments in the heart of the bustling business district, to help revive a struggling downtown and create jobs for residents. The second project, performed in EPA Region 9, provided affordable housing in San Diego, CA, and included upgrades to storm drains, water and sewer lines, underground powerlines, and streetscape improvements, significantly enhancing area infrastructure.
In both these projects and countless other projects performed under federal and state Brownfields programs, SCS is a trusted partner providing technical expertise and conscientious approaches to community engagement and planning that align with EJ protocols. SCS is a Foundational Member and Advisor of the Center for Creative Land Recycling (CCLR), which aims to turn abandoned land into thriving spaces that serve communities meaningfully.
This year’s Brownfields Conference theme was “Sustainable Communities Start Here,” in sync with SCS’s long culture and mission of achieving sustainability through holistic processes. The most successful remediation projects are when all stakeholders have a voice and redevelopment efforts are thoughtfully, creatively, and deliberately planned and implemented.
