The U.S. EPA is in the process of promulgating multiple regulations to address PFAS<\/a> levels in water and waste streams, some of which have elicited liability concerns from solid waste facility operators who say they are passive receivers of PFAS-containing material.<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

After years of anticipation for PFAS regulations,\u00a02024 is expected to be a key turning point.<\/p>

One of the most foundational proposals, the EPA\u2019s final drinking water standard, is imminent. The Office of Management and Budget\u00a0completed its review of the measure on March 27<\/a>,\u00a0and observers expect it could be finalized by mid-May to avoid potentially being repealed by a future Congress under the Congressional Review Act.<\/p>

\u201cIt\u2019s going to come out soon,\u201d said David Cash, EPA Region 1 administrator<\/a>.<\/p>

Anticipation for the proposed standard of\u00a04 parts per trillion for PFOA and PFOS<\/a>\u00a0has led to investments of time and in technology that can be used at wastewater treatment facilities and other sites. Cash cited filtration technologies such as granulated activated carbon, reverse osmosis and ion exchange as examples.<\/p>

\u201cBecause it\u2019s on the horizon, we know there\u2019s a huge amount of innovation and entrepreneurship that\u2019s going into solving some of these issues right now. And in our [regulations], we\u2019re not going to dictate technology, that\u2019s something we\u2019ve left up to the utilities, states and municipalities. The rule is flexible on timing<\/i>,\u201d\u00a0he said.<\/p>

Cash, who is co-chair of the EPA\u2019s PFAS Task Force, said in some cases states are also pushing their own standards and environmental officials often raise the issue of PFAS when he talks with them<\/p>

John Beling<\/a>, deputy commissioner for policy and planning at the Massachusetts Department of Environmental Protection, said his agency will issue regulations \u201cat least as stringent\u201d once EPA\u2019s final rule comes out.\u00a0<\/p>

The session also touched on potential hazards from applying biosolids, also known as sewage sludge, on farmland.<\/p>

\u201cWe are in the process of rethinking this whole thing;\u00a0unrestricted land application of substances that include PFAS probably isn\u2019t a good idea,\u201d said Beling.<\/p>

Adam Nordell,<\/a> a campaign manager with nonprofit Defend Our Health<\/a>, said his family\u2019s farm in Maine was polluted by this practice. Maine has a program to acquire PFAS-contaminated farms for research purposes and has enacted strict restrictions on land application of biosolids.\u00a0Nordell\u2019s group is advocating for the next farm bill to include language from a\u00a0federal bill<\/a>\u00a0that would provide financial assistance for affected farmers.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Science on landfill effects is evolving<\/h3><\/h6>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Many landfills have some level of PFAS<\/a> contamination due to receiving consumer and industrial products that contained the material, but the scientific community is still working to better understand the nuances of this issue.<\/p>\n

Researchers in Washington state analyzed 32 types of PFAS from leachate at 17 landfills<\/a> and found that 5:3 FTCA<\/a> was the dominant type. This correlates to items such as carpeting, textiles and food packaging. They found evidence that some older landfills had lower PFAS levels. They also found that manufacturers\u2019 efforts to phase out long-chain PFAS didn\u2019t necessarily lead to an overall reduction of the forever chemicals, because they were replaced with short-chain PFAS.<\/p>\n

Maine\u2019s Department of Environmental Protection also worked with 25 landfills<\/a> to take five leachate samples<\/a> over a two-year period. It also found 5:3 FTCA to be the dominant type, but levels varied widely. <\/p>\n

The agency has been studying effects on wastewater treatment plants that accept leachate, which accounts for an estimated 25% of the throughput at these sites in Maine.<\/p>\n

\u201cLandfills are definitely one source of PFAS loading to our wastewater treatment plants, but it\u2019s important to keep in mind it\u2019s not the only source,\u201d said Michael O\u2019Connor<\/a>, a senior environmental hydrologist with the agency. \u201cTreating just landfill leachate might not be a silver bullet, so to say, for decreasing loading at wastewater treatment plants.<\/i>\u201d<\/p>\n

Researchers at the EPA are also working to assess the PFAS impacts of normal and elevated temperature leachate on WWTPs. Initial results showed that elevated temperature leachate had higher concentrations of PFAS, but that didn\u2019t necessarily translate to significant effects for WWTP operations. The full results will be published in an upcoming study.<\/p>\n

Destruction technology is evolving fast<\/h3>\n

While some facility operators are waiting for final regulations before investing in concentration and disposal technology, others are moving ahead and many tests are underway.<\/p>\n

The EPA published interim guidance<\/a> in 2020 on PFAS destruction options, with another update pending. It detailed multiple concentration and disposal methods<\/a>. The U.S. Department of Defense, which has many PFAS-contaminated sites, published its own update on PFAS destruction last summer<\/a>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

The Oaktree's technology has been eveluated by EPA<\/h5>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

EPA tested Oaktree’s technology and could not find any PFAS, or PFOS in the Biochar; the destruction was between 97 – 99.9%. That is if Oaktree were to emit the gasses right away, which we don’t. We use the syngas to reheat the kiln and destroy the PFAS through this.\u00a0<\/p>

If we add our algae plant, then we can absorb landfill leachate and, end the toxic loop that currently is taking place.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
