Reprint of Press Release: EPA and Partners Announce Collaborative Implementation of the National Water Reuse Action Plan
WASHINGTON Feb. 27, 2020 — Today, at an event at the U.S. Environmental Protection Agency (EPA) headquarters in Washington, D.C., EPA Administrator Andrew Wheeler, U.S. Department of the Interior Secretary David Bernhardt, and U.S. Department of Agriculture Secretary Sonny Perdue, and White House Council on Environmental Quality Chairman Mary B. Neumayr joined federal, state, tribal, local and water sector partners to announce the National Water Reuse Action Plan: Collaborative Implementation (Version 1). The actions that EPA and its partners commit to in the Action Plan will help strengthen the sustainability, security and resilience of our nation’s water resources by creating new partnerships, providing accountability and promoting communication and transparency with a new online platform.
“A reliable water reuse program provides great opportunity for alternatives to existing water supplies across the nation to enhance water security, sustainability, and resilience for communities, rural and urban alike, across the country,” said EPA Administrator Andrew Wheeler. “By launching this phase of the National Water Reuse Action Plan, federal agencies are driving progress on this national priority and delivering on President Trump’s commitment to ensuring a reliable supply of water for our nation.”
“Under President Trump’s leadership, we are pursuing an aggressive approach to ensuring reliable and secure water delivery—driven by modern technology and the best possible science. As our water users are preparing for the future—by strengthening their own water systems and integrating new technologies—collaboration across federal partners is critical to supporting rural and urban water users alike. The National Water Reuse Action Plan will guide the Administration’s efforts to provide safe, affordable, and reliable water to the American people,” said U.S. Secretary of the Interior David Bernhardt.
“President Trump and his Administration are committed to making it easier for farmers to succeed and to ensure they are the most innovative in the world. Administrator Wheeler’s action plan on water reuse will help inspire creative, problem-solving that boosts production on farms, ranches, and private forests – ultimately improving water quality, soil health, and wildlife habitat,” said U.S. Secretary of Agriculture Sonny Perdue.
“As we pursue practical approaches to address our nation’s most pressing environmental challenges, including water scarcity, this Administration strongly supports developing modern, resilient infrastructure to effectively manage our nation’s water resources,” said White House Council on Environmental Quality Chairman Mary B. Neumayr. “One way to support our nation’s communities, economy and environment is by continuing to develop additional opportunities for water reuse to promote safe and reliable water supplies for our homes, businesses, agricultural communities, recreation, and healthy ecosystems. The National Water Reuse Action Plan is a practical example of agencies coming together to improve use of technology to increase water reliability and better manage our nation’s water resources.”
“The Department of Energy is delighted to support EPA’s efforts on the National Water Reuse Action Plan through our Water Security Grand Challenge,” said U.S. Department of Energy Assistant Secretary for Energy Efficiency and Renewable Energy Daniel R. Simmons. “Water is a critical resource for human health, economic growth, and agricultural productivity. We are calling on the power of competition and drawing on the strengths of our partners and stakeholders to advance transformational technology and innovation to meet the global need for safe, secure, and affordable water.”
“Our nation is blessed with abundant access to safe and reliable water sources throughout our country. However, as our country and economy continues to expand, we must ensure that this reliability continues for future generations. I am pleased the administration has taken a forward-looking approach to include federal, state and tribal agencies, along with a multitude of diverse stakeholders, to put out the WRAP. It is an example of the good that comes when government and the private sector work together to lay out practical suggestions to steward our natural resources well,” said Congressman Bruce Westerman (AR-04).
“Finding new ways to preserve and protect water in Oklahoma is one of our top priorities as a state. Today’s release of the “Water Reuse Action Plan” shows that the federal government is serious about leading in their mission to assist all 50 states as well as sovereign tribal nations in developing valuable resources out of previously worthless water. These goals cannot happen without the full partnership of states, tribes, local governments and our federal partners across all agencies working together. Kudos to the Trump Administration and Administrator Wheeler for their leadership in this important endeavor,” said Oklahoma Secretary of Energy & Environment Ken Wagner.
“The U.S. Department of State is excited to use the WRAP as a tool to raise awareness about water reuse around the world. By encouraging partner governments to adopt water re-use policies, management approaches, and new technologies – many of which were made here in America – the State Department is helping to implement the President’s Global Water Strategy. And, through our outreach efforts, all of the people and agencies who contributed to the WRAP are also helping to make other nations more water-secure,” said Principal Deputy Assistant Secretary of State for Oceans and International Environmental and Scientific Affairs Marcia Bernicat.
“The U.S. Army Corps of Engineers continues to work with its federal partners and local sponsors to identify opportunities and include water reuse features in congressionally authorized Civil Works projects,” said Principal Deputy Assistant Secretary of the Army for Civil Works Ryan Fisher.
Over the next decade, 40 states anticipate some freshwater shortages within their borders. The Action Plan supports the President’s memorandum on Promoting a Reliable Supply and Delivery of Water in the West and will help advance water reuse technology that has the potential to ensure the viability of our water economy for generations to come. The Action Plan is a collaborative effort that represents the first initiative of its magnitude to be coordinated across the water sector and builds on more than four decades of water reuse experience and practice. It frames the business case that water reuse is a viable and growing means of supporting our economy and improving the availability of freshwater for farmers, industry, communities, and ecosystems. The Action Plan identifies 37 specific actions across 11 strategic themes to be led by a spectrum of federal, state, local and private sector interests. The Action Plan reflects new partnerships, generates action through more than 200 initial implementation milestones and provides accountability through transparency and routine progress updates.

Produced water and flowback water are generated from the CBM, shale gas, and shale oil wells. Produced water is water that is withdrawn from the coal seam and shale through the vertical wells drilled into the coal seam and shale in order to release the hydrostatic pressure to enable gas/oil collection at the surface.
Flowback water is used to fracture coal seam cleats and shale in order to open the fissures that enable the release of the gas from the formation if the natural fissures are not fully developed. This water is pumped into the formation and then eventually collected at the surface in a manner similar to the collection of the produced water.
SCS Engineers employs several technologies to reuse, or at the end of the reuse cycle, dispose of production and flowback water.
PFAS are a class of synthetic fluorinated chemicals used in many industrial and consumer products, including defense‐related applications. They are persistent, found at low levels in the environment, and bio‐accumulate. Studies have shown these compounds being detected more often in surface water, sediments and/or bioaccumulated into fish tissue. Because of the greater affinity of longer chain per‐ and polyfluoroalkyl substances (PFASs) compounds for fish than other environmental matrices, certain compounds are often found in fish tissue, but not in the water or sediment. Table 1 shows average concentrations of PFOA and PFOS in landfill leachates around the world. The USEPA health advisory level is 70 ppt for PFOA and PFOS.
Table 1. Concentrations of PFAS compounds in Landfill Leachate around the world
Treatment Options for PFOS and PFOA
The removal of PFASs from drinking water has been the USEPA’s national priority. Recent discoveries of PFAS/PFOS in drinking water in multiple states in the US has heightened interest in these emerging contaminants. Federal, state, and local agencies are formulating regulatory limits that vary greatly. These limits seem to be centered on drinking water, but these developments are driving disposal of existing stores of chemicals containing PFAS/PFOS and environmental media contaminated with PFAS/PFOS
Treatment processes that can remove PFAS chemicals from drinking water may include high-pressure membrane systems such as RO, granular activated carbon (GAC), or ion exchange as shown in Figure 1. The more conventional water treatment technologies such as (e.g., aeration) are not typically effective.
Landfill Leachate RO Treatment Plant – New Hanover County, North Carolina
New Hanover County upgraded its leachate treatment system to meet stricter regulatory standards for surface water discharges, particularly standards relating to metals (arsenic) and ammonia. Sampling by NC DEQ showed the new RO plant is filtering out PFAS. Table 2 shows the results from February 2019.
Figure 2. New Hanover County Leachate and PFAS Treatment Plant
Table 2. Concentrations of PFAS compounds in Leachate at New Hanover County Landfill
|PFAS Constituent||Raw||Treated||Surface water|
|PFOA (ppt)||1,250||< 0.6||3.9|
|PFOS (ppt)||228||< 0.6||7.1|
Comparison of GAC Types for PFOA and PFOS Removal
Four different types of GAC, i.e., Re-agglomerated Bituminous, Lignite, Enhanced Coconut and Enhanced Coconut (Blend) were evaluated under identical operating conditions and influent water quality. Figure 4 shows results from these four GAC products for PFOA/PFOS removal vs time.
Figure 4. GAC Treatability study for removal of PFOA and PFOS
Re-agglomerated bituminous coal GAC (FILTRASORB) significantly outperformed: Lignite, Enhanced Coconut and Enhanced Coconut (Blend).
PFAS compounds are of concern because they do not break down in the environment, bioaccumulate in humans and biota, and may pose risks to human health
GAC, Synthetic adsorbent, and ion exchange resins are widely used for PFAS removal. Capacity and leakage of PFASs into the treated water varies depending on the specific PFASs, the type of adsorbent used.
PFAS removal may be influenced by pH, water temperature, contact time, Natural Organic Matter, and chlorine. For complete PFAS removal, a polishing may be required.
Disposal methods for PFAS waste streams include high-temperature incineration or landfilling. Landfilling is not favored since the PFAS load would increase, and many landfills will not accept PFAS waste.

Managing landfill leachate and wastewater treatment are increasingly challenging and costly for landfill owners and operators. In some cases, publicly owned treatment works (POTWs) are required to impose limitations on liquids received at their facilities, resulting in increased charges, or the POTW could refuse to permit or process the leachate wastewater altogether. These developments are due in part to more stringent discharge requirements and the shift to newer disinfection technology that has limited the POTW’s ability to accept higher strength wastewaters. As a result, many facilities and landfill operators are facing higher costs and fewer options for disposal.
Another factor that affects landfills is the fact that the composition of leachate in landfills differs depending on the degree of leachate stabilization and a seasonal increase in quantity as well as on the influence of more frequent and higher intensity storms due to changing climatic conditions.
The single most influential factor on the volume of landfill leachate is precipitation. The most influential factor regarding leachate quality is that leachate typically contains high concentrations of organic compounds, ammonia and other forms of nitrogen, metals, and dissolved solids. Ammonia concentrations in the leachate, from many landfills, are increasing every year as shown in the graph below. Compounding the high strength concentrations of constituents found in landfill leachate are the emerging contaminants of concern including per and poly-fluoroalkyl substances (PFAS) that are now a significant concern with the U.S. EPA and many state environmental agencies.

Following the release of the U.S. Environmental Protection Agency’s PFAS Action Plan, many states have begun to draft plans and take action to address per- and polyfluoroalkyl substances (PFAS).
PFAS have been used in the production of a wide range of industrial and household products, including fire suppressant foam (Aqueous Film-Forming Foams or AFFF) stored and used at airports and aviation facilities for example. Peripatetic in water, PFAS are in the environment and detected in humans.
Nationwide PFAS Sampling and Analyses Plans
States and the federal government are launching programs to sample stormwater, groundwater, and wastewater for the more common PFAS substances at aviation facilities, firefighter training facilities, military bases and training centers, petroleum refineries and terminals, and petrochemical production facilities.
Other secondary sources, such as landfills, wastewater treatment plants, and where biosolids are used in agricultural applications, are preparing for more aggressive water and environmental testing to help the states determine the potential exposure through drinking water due to the tendency of the substances to accumulate in groundwater.
Many states, such as California are focusing on PFAS analytes including PFOA and PFOS. Massachusetts, for example, is focusing on a subset of PFAS compounds – PFOA, PFOS, PFHxS, PFHpA, and PFNA, because these compounds are considered a threat to human health at high levels. According to the Center for Disease Control (CDC), blood levels of both PFOS and PFOA have steadily decreased in U.S. residents since 1999-2000, but only water and soil-sampling plans can help narrow down potential sources and those facilities that may have accumulated PFAS historically. Although not an exhaustive list, they are a sound and reasonable start, which accredited laboratories are capable of detecting, analyzing, and can be treated with available technology.
Focus on California’s Phased Plan – Phase I for Airports, Aviation Facilities, Landfills
In our blog, we’ll focus on California and the State Water Resources Control Board’s (SWRCB) PFAS Phased Investigation Approach published on March 6, 2019. On March 20, 2019, the SWRCB initiated Phase I of its investigative plan by issuing orders to 31 airports, over 250 landfills, and over 900 drinking water wells to obtain PFAS data across the state. The order issued to airports entitled “Water Code Section 13267 Order for the Determination of the Presence of Per- and Polyfluoroalkyl Substances – Order WQ 2019-0005-DWQ,” requires source investigation and sampling at airports. We’ve linked to the PDF for airports here. Phase II will cover refineries, bulk terminals, non-airport fire training areas, and 2017-2018 urban wildfire areas. Phase III will cover secondary manufacturers, wastewater treatment plants and pre-treatment plants, and domestic wells.
The Order requires the facilities to submit a Technical Report to the Regional Water Board upon notification. For example at aviation facilities, an “Airport Operator Questionnaire” is due to the Regional Water Board within 30 days and other requirements including a Work Plan for a one-time preliminary site investigation within 60 days of receiving order notification. Submission of the final sampling and analysis report for each facility is due 90 days following the State or Regional Water Board acceptance of the facility’s Work Plan.
Hire a State-licensed Professional Geologist or Professional Engineer
While the schedule is aggressive, professional engineers familiar with these investigations and reporting requirements can meet the timetable. What should facility owners and managers expect from their professional geologist or engineer? A complaint investigation of possible PFAS releases at your site will include all of the following:
Preparation of the state required documents including a work plan for the preliminary site investigation.
A site map with sample locations, PFAS material storage and use areas, probable release areas including firefighting training areas, crash sites, and spills from handling.
The report needs to identify sensitive receptors such as municipal supply wells, domestic wells, and surface water bodies within a one-mile radius of a suspected source area.
Proposed surface and subsurface soil sampling locations to delineate the surficial and vertical extent of impacts where PFAS were applied to land.
Proposed representative groundwater sample locations in proximity to a suspected source area.
Existing monitoring wells for your facility may be used if located in proximity to PFAS source(s), and groundwater samples would be representative of groundwater conditions. If the groundwater gradient is unknown, at a minimum, three groundwater samples will be collected around the source area.
The sampling and analysis plan for compounds and parameters specified by the state that includes quality assurance and quality control procedures necessary to ensure valid and representative data is obtained and reported. Your engineer or geologist will determine the appropriate sampling procedures, including sampling equipment, sampling containers, the quality of water used for Blank preparation and equipment decontamination, sample holding times, and quantities for sampling PFAS compounds.
Best practices will minimize contamination, so all sampling materials, equipment, blanks, containers, and equipment decontamination reagents used in sampling must be PFAS free, to the maximum extent practicable.
Include all reporting limits for PFAS.
The signature, stamp, and contact information of the California-licensed Professional Geologist or Professional Engineer responsible for the content of the Work Plan.
The Final Report should include the final sampling and analysis report, submitted no later than 90 days following the State or Regional Water Board acceptance of the Work Plan. This report should include a description of the sampling activities; a summary table of analytical results; the Chain of Custody; the field sampling log; and boring logs and any temporary/permanent monitoring well construction details.
The report will also contain the site map showing the sampling/monitoring locations, and a copy of the laboratory analytical results of the monitored media.
The Questionnaire is to be completed and submitted within 30 days if your facility has not discharged, disposed of, spilled, or released in any way, AFFF or other PFAS containing materials to the land at your facility, or if you have already conducted sampling for these constituents in compliance with the minimum work plan requirements.
The Questionnaire, the Work Plan, and all other reports and analytics are submitted in a searchable electronic format, with transmittal letter, text, tables, figures, laboratory analytical data, and appendices in Portable Document Format (PDF) format and in electronic data deliverable (EDD) format to state’s GeoTracker website via the Electronic Submittal of Information (ESI) Portal.

We will continue to see changes on the federal, state and local regulatory front that together will help us manage storm water in a smart, cost-effective manner preserving our water resources. Betsy Powers of SCS Engineers provides an update in her most recent article.
Until a new WOTUS definition is finalized, the U.S. EPA and the U.S. Department of the Army have indicated their intent to re-codify the pre-Obama regulations. The revised WOTUS rule is expected to include looser regulatory requirements, meaning fewer waters will qualify, and therefore, fewer permits will be required.
To speed up approvals of permits for highways, bridges, pipelines and other major infrastructure, an Obama-era executive order aimed at reducing exposure to flooding, sea level rise and other consequences of climate change were rolled back reducing the environmental reviews and restrictions on government-funded building projects in flood-prone areas.
Removing phosphorus from storm water runoff is a hot topic, with partners exploring alternative opportunities to reduce the introduction of phosphorus in runoff, remove it or manage it in watersheds.
More proprietary filters are being used for pretreatment before underground infiltration for redevelopment sites for total suspended solids (TSS) control and where land is limited. The performance of proprietary devices continues to be studied and improved to meet regulatory requirements. Increasing general attention is being paid to emerging contaminants that are problematic in storm water runoff. Among the emerging contaminants of concern are pharmaceutical and personal care products, pesticides, hydrocarbons, and hormones. Many of which are now included within the Endocrine Disrupting Chemicals group.

Of interest to industries concerned with wastewater ammonia treatment or landfill leachate ammonia treatment.
SCS Engineers publishes a new SCS Technical Bulletin entitled “Treatment of Ammonia in Wastewater and Leachate – Considerations and Technologies.”
Reducing the amount of ammonia in landfill leachate and other industrial wastewaters are often necessary to meet discharge standards. Proven wastewater treatment technologies can effectively reduce ammonia concentrations, but selecting the right technology requires careful consideration. This SCS Technical Bulletin provides background on ammonia in wastewater, and reviews factors to consider in selecting a treatment technology. The Bulletin includes a review of eight of the most common and effective treatment and disposal methods for wastewater with elevated ammonia or nitrogen.
The partnership expands the availability of complex wastewater treatments for landfill leachate and industrial effluents.
SCS Engineers (SCS), and WEHRLE Umwelt GmbH (WEHRLE), today announced the availability of integrated services between the two firms to streamline the design-build of leachate treatment facilities in the United States.
SCS’s depth of experience with the engineering, construction, operations, monitoring, and management of U.S. landfills, as well as industrial wastewater treatment systems, and WEHRLE’s depth of experience designing landfill leachate and industrial wastewater treatment plants around the world creates opportunities for both firms to bring more sustainable solutions to their clients.
In the last several years, U.S. landfill owners and operators are increasingly under pressure to meet more strident water quality demands while keeping their rates low. Selecting the most effective method of treatment at a sustainable cost requires advanced landfill engineering expertise, waste management expertise, and excellent knowledge of which proven wastewater treatment technologies will perform best depending on the type and location of the landfill, the leachate composition, and the volume of leachate generated, among other considerations.
“The SCS Engineers and WEHRLE Umwelt teaming agreement brings a world of talent and technologies to our U.S. clients, improving our support to the private and municipal solid waste industries, with the responsibility of generating cleaner wastewater,” said Samuel Cooke, an SCS vice president, and the firm’s national liquids management director.
“As global technology leader for the treatment of complex wastewaters, WEHRLE has built up an excellent reputation in over 40 countries worldwide with more than 250 installations. Detailed customized consultation upfront the projects is important to us – especially since we are dealing with multiple technologies that require explanation and competence. SCS with its technological knowledge and background of U.S. waste industries is for us the perfect match to bring best long-term economical solutions to demanding customers.” said Frank Natau, WEHRLE’s Senior Expert for treatment of leachate and waste-derived effluents.
