What are PFAS or “Forever Chemicals” and Why Should We Care on the Coastside?

 

ARTICLE. ā€œDARK WATERSā€ COME TO ORANGE COUNTY by Jeremy N. Jungreis and Jason Dadakis

Every generation seems to face a new challenge in cleaning up or remediatingĀ  chemicals previously believed to be safe.Ā  In the past, it was Polychlorinated Biphenyls (PCBs) routinely sprayed on dirt roads to suppress dust, or volatile organic com pounds (solvents or VOCs) ubiquitous in dryĀ  cleaning and other degreasing operations thatĀ  leaked into the groundwater. Both chemicalsĀ  were allegedly linked to increased cancer riskĀ  and other adverse health effects through a variety of exposure pathways—including drink ing water.

Many of the VOC and PCB sitesĀ  have now been cleaned up, but not withoutĀ  expensive litigation spanning decades. Now,Ā  as chronicled in the recent motion pictureĀ  Dark Waters, there is growing concern aboutĀ  a new class of chemicals with the potential toĀ  adversely impact human health and the environment in Orange County. Per- and polyfluoroalkyl substances, abbreviated as PFAS, andĀ  nicknamed the ā€œforever chemicalsā€ becauseĀ  of their resiliency in the environment, areĀ  now receiving extraordinary regulatory scrutiny—spurring strict new state regulations andĀ  spawning litigation throughout the country.

 

What are PFAS, and Why Should I Care?

Perfluorooctanoic acid (PFOA) and per fluorooctane sulfonate (PFOS) are the two PFAS in the regulatory crosshairs of the StateĀ  of California and the Federal EnvironmentalĀ  Protection Agency (EPA). However, there areĀ  thousands of unique PFAS that have enteredĀ  the stream of commerce in the United States,Ā  and by extension, the environment, over theĀ  last fifty years.

What makes PFAS cleanupĀ  such a difficult regulatory problem is thatĀ  PFAS are literally everywhere. They are inĀ  Scotch Guard, GoreTex, Teflon, and count less other household products. Moreover, recent evidence suggests that our own bodiesĀ  may have become a source of PFAS discharges to the environment—with PFAS residualsĀ  showing up in wastewater treatment plantsĀ  throughout Southern California.

Recent studies suggest prolonged exposureĀ  to some types of PFAS, and in particular,Ā  PFOA and PFOS, may be associated withĀ  potential adverse effects on human health.Ā  According to the EPA, there are associationsĀ  between PFOA exposure and high cholesterol, increased liver enzymes, decreased vaccination response, thyroid disorders, pregnancy induced hypertension and preeclampsia, andĀ  testicular and kidney cancer. The EPA indicates there is also possible association between PFOS and high cholesterol, decreases in fertility, and decreased birth weights.Ā 

PFAS chemicals have been detectedĀ  in water sources throughout the Unit ed States, but for reasons uniqueĀ  and complex, PFAS are particularlyĀ  prevalent in the inland portion of theĀ  Orange County Groundwater Basin (OCĀ  Basin) underlying much of northern and central Orange County. The result is a highlyĀ  dynamic situation. Water agencies withinĀ  the OC Basin have received strong recommendations from state regulators to shutĀ  down—until such time as expensive treatment can be designed and implemented—upĀ  to seventy-one separate wells, amounting toĀ  temporary curtailment of a large portion ofĀ  northern and central Orange County’s waterĀ  supply. These shut downs are set to occur during the first half of 2020.Ā Meanwhile, litigation against PFAS manufacturers, and otherĀ  parties responsible for releasing PFAS into theĀ  environment, is on the near horizon, alongĀ  with new legislation, and possible admin istrative challenges to actions taken by theĀ Ā State Water Resources Control Board Division of Drinking Water (DDW).

 

How Did We Get Here?Ā 

As the movie Dark Waters chronicles, concerns over the safety of PFAS are not new—atĀ  least in parts of the country where PFAS is manufactured. According to the allegations of plaintiffs in West Virginia and Ohio, manufacturers of PFOS and PFOA have known about the potential dangers of PFAS for a long period of time, and they allegedly tried toĀ  cover it up.Ā 

In 2017, DuPont and ChemoursĀ  agreed to pay $671 million to resolve multi-district litigation in Ohio that alleged thatĀ  DuPont improperly dumped cancer-causingĀ  chemicals, thereby harming people exposed to the chemicals through drinking water and other exposure pathways.

In 2018, 3M reached an $850 million deal with the State ofĀ  Minnesota settling litigation that alleged 3MĀ  knowingly dumped chemicals into groundĀ water, impacting local wildlife and posing health risks to local water supplies.

Revelations from the litigation in the Midwest spurred the EPA to action.

In May 2016,Ā  the EPA released a Lifetime Health Advisory of a combined 70 parts per trillion (ppt) forĀ  PFOS and PFOA in drinking water.

In July 2018, DDW, which directly regulates California public water systems, established interimĀ  drinking water Notification Levels (NL) and Response Levels (RL) for PFOA and PFOS, based on recommendations from the California Office of Environmental Health HazardĀ  Assessment (OEHHA). Results above theĀ  NL required water agencies to notify theirĀ  local governing body (i.e., city council) and the governing bodies of other local agencies.Ā  DDW also set an RL for PFOS and PFOA at the same level as the EPA advisory.

In April 2019, DDW sent monitoringĀ  orders to more than 200 public water systemsĀ  across California, including many in OrangeĀ  County, requiring suppliers to test for PFOAĀ  and PFOS. The list of monitoring ordersĀ  included 612 drinking water supply wells selected on the basis of proximity to landfills, municipal airports, and locations with pastĀ  detections of PFAS.Ā 

In August 2019, DDW announced a new Notification Level for PFOA and PFOS, 5.1Ā  parts per trillion (ppt) and 6.5 ppt, respectively, based on new recommendations fromĀ  OEHHA. The RL for PFOA and PFOS would temporarily remain at the EPA level of 70 pptĀ  for both contaminants. However, DDW indicated informally it was likely to revise the RLsĀ  to levels significantly below EPA advisory levels, 40 ppt for PFOS and 10 ppt for PFOA.

TheseĀ  suggested low levels would cause a significantĀ  number of wells within inland north-centralĀ  Orange County to be in non-compliance with DDW’s proposed standard without any kind of public regulatory process.

Meanwhile, theĀ  California legislature, not content with allowing regulation of PFAS and PFOA to proceed via the normal regulatory process, passed ABĀ  756. AB 756 requires water agencies who confirm PFAS in a drinking water source above the a designated RL, to either remove the sourceĀ  from service within thirty days or engage in an extensive public notification campaign, in multiple languages, and in print, electronic, andĀ  newspaper forums, that ensures every singleĀ  customer of the water agency receives noticeĀ  of the exceedance, the possible health effects ofĀ  PFAS, and the agency’s decision not to take theĀ  drinking water source out of service.Ā 

AB 756 took effect on January 1, 2020. The new RLs for PFOS and PFOA were not far behind. DDW released them, without formal regulatory process or public hearing, on February 6, 2020.

As anticipated, the RL forĀ  PFOA was set at 10 ppt, and the RL for PFOSĀ  at 40.

In the same advisory, DDW indicated it was considering establishing NLs and RLs for seven other classes of PFAS.Ā DDWĀ  concurrently issued guidance indicating AB 756’s public notification requirements wouldĀ  apply prospectively via a running annualĀ  average of quarterly samples, providing additional time for local agencies with PFOA or PFOS detections to come into compliance without triggering AB 756’s public notification requirements.

 

A De Facto Maximum Contaminant Level

The magnitude of the RL for PFOA in Orange County is significant—42 wells tested to date exceed the RL with approximately 30 more projected to exceed the new RLĀ  should testing be expanded. This fact, combined with the dearth of scientific evidenceĀ  supporting the lower RLs, and the extremelyĀ  stringent notification requirements triggered by AB 756, has led some attorneys to contend that DDW has engaged in the setting of a de facto maximum contaminant level (MCL) that violates California administrative law.Ā The setting of an enforceable MCL is aĀ  process that ordinarily requires significantĀ  scientific (epidemiological and toxicological) study, and a thorough cost/benefit analysis.Ā  New Hampshire, seeking to be one of theĀ  first states to set an enforceable MCL forĀ  PFOS and PFOA (and two other PFAS com pounds), learned this the hard way when theirĀ  MCL was enjoined by a New HampshireĀ  state court judge on December 31, 2019.18 The court in New Hampshire enjoinedĀ  enforcement of the MCL, which took effectĀ  on September 30, 2019, putting on hold New Hampshire’s 12 ppt for PFOA and 14 ppt forĀ  PFOS standards.Ā 

Back in California, recent actions by DDWĀ  to set the revised RL for PFOA and PFOS raiseĀ  some of the same concerns as those expressedĀ  by water agencies in New Hampshire, namelyĀ  an overly rapid process, inadequate publicĀ  participation opportunities, and an unwillingness by regulators to follow the proceduresĀ  set forth in the Federal Safe Drinking WaterĀ  Act (SDWA) for setting enforceable drinkingĀ  water standards. California regulators wouldĀ  likely respond to that criticism by contending that the RLs are not mandatory and thatĀ  the law, as currently written, does not requireĀ  public participation or comment prior to RLĀ  implementation; RLs are, DDW would likelyĀ  argue, just very strong suggestions.Ā 

It remains to be seen whether formal challenges will be filed to the recently promulgated RLs. However, in the meantime, agencies such as the Orange County Water DistrictĀ  (OCWD), which manages the OC Basin, are working to implement technical and engineering solutions that can rapidly bring ground water pumping lost to PFAS contaminationĀ  back online. OCWD is also working withĀ  other interested agencies and the legislature toĀ  develop a regulatory process for the setting ofĀ RLs that provides greater predictability, scien tific rigor, and public participation as a formalĀ  part of any future RL development.Ā Ā 

 

Tort Suits by Local Governments andĀ  States to Recover Damages for InjuriesĀ  to Drinking WaterĀ 

Litigation against PFAS manufacturers has exploded during the last year, with thousands of claims now pending against PFAS manufacturers in multi-district litigation currently pending in the Federal District Court for the District of South Carolina,Ā as well as inĀ  various state court actions around the UnitedĀ  States. State attorneys general, in states such as New Hampshire, Vermont, New York,Ā  Michigan, and New Jersey, have becomeĀ  involved too—filing lawsuits against PFASĀ  manufacturers and alleging billions of dollars in damages for personal injury, naturalĀ  resource, and property damage.Ā 

The manufacturers, for their part, contend PFOS andĀ  PFOA are not shown to harm human health,Ā  and that any release to the environment was consistent with federal law and, in some cases, military specification. How such litigationĀ  is resolved remains to be seen, but the recent large settlements in Ohio and MinnesotaĀ  suggest there is potentially willingness on theĀ  part of at least some manufacturers to limit exposure through settlement—particularlyĀ  where the plaintiffs can demonstrate directĀ  discharges by a manufacturing facility thatĀ  caused natural resource or aquifer damage.Ā 

PFAS, and the statutory, regulatory, and litigation actions it has catalyzed, promises to beĀ  an issue relevant to Orange County residentsĀ  (and their lawyers) for the foreseeable future

VIDEO. Two pump failures in last two weeks.

Wipes and rags, as seen below, are the culprit.

Talk to your neighbors, please.

Repair for one pump can be $50,000.

Replacement is very, very expensive. A new pump can be a million dollars.

Burning out a generator can cost $100,000 to replace

Smaller Is Better: The Solution to California’s Ancient Water PipesĀ by Rinaldo Veseliza

Smaller Is Better: The Solution to California’s Ancient Water Pipes

Our aging infrastructure is a ticking time-bomb underground. We can begin to help repair it and stave off future trouble by reaping the benefits of smaller, decentralized microgridĀ systems.

A system at the San Francisco Public Utilities Commission helps recycle water for on-site reuse for irrigation and other needs.Tara Lohan

 

AS A PRACTICINGĀ architect andĀ LEEDĀ APĀ (Leadership in Energy and Environmental Design, Accredited Professional) for more than 40 years, I have scoured the planet for technological solutions to improve sustainability with water, energy and waste treatment. During the course of my projects, I often see the underbelly of the beast where aging underground systems have the potential to erupt at any time, particularly in earthquake-prone areas such as California’s San Francisco Bay and LosĀ Angeles.

Our greatest current and growing problem is restoring and improving infrastructure systems to last another 50 years. We cannot fix all the massive underground problems, but we can instead replace them with smaller, local surface-mounted solutions that will lead us to more flexible, manageable, decentralized and sustainableĀ systems.

It is the equivalent of, in communication technology, switching from giant mainframes to using cellphones. The technology is all available, automated and user-friendly. Microgrid technologies started withĀ NASAĀ space missions where astronauts recycled all their waste into water and created their own power on board. It is now time to apply our inventions and sustainability principles through our communities to a larger spaceship – ourĀ planet.

The infrastructure started in primitive little towns across the world, then septic systems were replaced by larger central plants and distribution systems as cities grew. Waste treatment plants were moved away from town centers to where the smell could be dissipated and tolerated. As cities grew, all the infrastructure expanded into a massive network to manage everyone’sĀ needs.

Today, as much of this infrastructure is dated, landlocked or falling apart, we should consider reverse-engineering the concept of distribution so that small communities, large buildings and individual homes can provide their own water, renewable energy/power (and storage) as well as waste-waterĀ treatment.

It is difficult to fix hundreds and thousands of miles of underground piping that we cannot see. Most municipalities do not even acknowledge its existence, especially in times of economic difficulties. Deferred maintenance has been a problem in citiesĀ worldwide.

Centralized systems were great, big, expensive and ā€œpermanentā€ solutions for growing communities during their earlierĀ development.

Now, as these overgrown, dense cities are overwhelmed with growing populations, we need smaller-scale microgrids, which can remove the mystery of processing stormwater and sewage water into usable/potable water with self-contained prefabricated modular systems and automated quick-response services. Decentralized waste-water processing and recycling microgrids will actually create many more jobs than our current central systems. They will also reduce the potential impact of cyber attacks and massive systemĀ outages.

For example, for about $3,000, a traditional home can be outfitted to recycle 80 percent of its waste-water and use it locally, reducing the need for potable water by that same amount. Office complexes can treat and recycle their own waste to 80 percent recycling onsite for irrigation, toilets and cooling systems. City blocks can also recycle their waste-water locally and reprocess it mechanically to re-use onsite, significantly reducing costs for upgrading their failing undergroundĀ piping.

These smaller-scale solutions can each reduce the need for potable water by 80 percent, which would be a major accomplishment for our society. They exist now and should be utilized in all future buildings as well asĀ retrofitted.

In a city with many hills like San Francisco, where pumping uphill can be costly, the local solution can solve many current problems, including savings in replacement costs, increases in efficiency and greater flexibility with maintenance and operations. The technology has been around for a long time, but municipal politics has prevented any such conversions, often citing potential public health risks as the main reason for not abandoning existing centralizedĀ plants.

Yet the aging, leaking underground sewage pipes are causing growing numbers of system spills which have a significant impact on public health. We cannot see all the damage caused until it is too late, after our underground water sources are polluted. Many municipal systems are finally looking into recycling a small percentage of the water they currently process andĀ dump.

Refurbishing our existing communities, buildings, homes and infrastructure is a massive undertaking. However, with newer technologies at lower costs, we can re-design our own facilities but also export the collective knowledge throughout the world. As usual, the Europeans are somewhat ahead of the game because of visionary/mandated governmental initiatives to improve efficiency, particularly with solar photovoltaic, wind, hydroelectric, waste-to-energy plants and biomass power generation. We have made great progress in recent years in re-inventing our building technologies and reviving our leadership inĀ engineering.

Solar power is the best example of technology that is already modular, local and self-supporting, providing our energy needs at source, creating the opportunity for microgrids to replace long-distance power transmission systems and associated inefficiencies. Smaller isĀ better.
