Military Bases Have High Concentrations of Per and Polyfluoroalkyl Substances (PFAS)

Military Bases Have High Concentrations of Per and Polyfluoroalkyl Substances (PFAS)

***Updated 8/29/18 to include video***

Analies Dyjak | Policy Nerd   

Per and Polyfluoroalkyl Substances (PFAS) have been receiving a ton of media attention throughout this past year. PFAS are a category of toxic contaminants that have invaded public and private drinking water systems across the entire country. Military bases are extremely susceptible to this type of contamination because of necessary on-base activities. If you would like to learn more about what PFAS are, their health effects, and if they're regulated, please click here. 

Why Do Military Bases Have High Concentrations of Per and Polyfluoroalkyl Substances (PFAS)?

Military bases have historically had issues with pollution, due to the nature of on-base activities. Municipal fire departments also travel to nearby military bases because they provide an open, secure area to train. So not only are military personnel being directly exposed to PFAS chemicals in water, but so are local fire departments. The Department of Defence isn’t necessarily to blame for the high rates of contamination of PFAS on military bases. The Manufacturers of PFAS-containing fire fighting foam who actively sell to the DOD are greatly at fault. Because there is no effective alternative on the market, the military has no choice but to continue purchasing and using these products. Unlike many other countries, the United States doesn’t use the precautionary principle in chemical manufacturing. This means that chemicals are introduced to the market before toxicological due diligence is completed. Most of the time it takes someone getting extremely sick for manufacturers to even begin to pay attention.

More often than not, military bases have their own underground private wells that provide drinking water to families living on base, rather than being apart of a public drinking water system. Fire fighting foam can either directly percolate into soil, or run off into surrounding surface water sources. Water from contaminated soil naturally recharges on-base drinking water wells, which families consume on a daily basis.

What Is The Department of Defense Doing About Per and Polyfluoroalkyl Substances (PFAS) on Military Bases?

The most recent data provided by the DOD stated that 99% people receiving non-DOD-treated water were served by systems with no violations, whereas only 89% of people receiving DOD-treated water were served by systems with no violations. It’s important to note that these data are from bases that voluntarily tested for PFAS chemicals in water, but they do however reiterate that military bases have higher concentrations of this contaminant than other areas in the country. In October of 2017, the US Government Accountability Office reported that the Department of Defense has taken action on PFAS. DOD has directly shut down wells or provided filtration to 11 military installations. This is definitely a step in the right direction, but there are over 400 military bases in the United States that are still contaminated. Approximately 3 million people in the US drink water provided by the DOD. Not only are active military personnel at risk, husbands, wives and children are being adversely impacted by PFAS chemicals in water. Again, manufacturers of these dangerous chemicals are mostly to blame for such high concentrations of PFAS contamination on military bases.

What Are Public Officials Doing About Per and Polyfluoroalkyl Substances (PFAS)?

EPA set a Lifetime Health Advisory Level of 70 parts per trillion for both PFOA and PFOS. The rule of thumb for PFAS is that the sum of the category of contaminants should be no higher than 70 parts per trillion. ATSDR believes this level should be reduced to 20 parts per trillion for drinking water. Again, Lifetime Health Advisory Levels and Minimum Risk Levels are non-enforceable limits that municipalities are not required to follow. DOD has not developed their own standard for PFAS in drinking water and therefore follow the non-enforceable national level of 70 parts per trillion. DOD is not at all incentivized to create a standard or even test for PFAS, because of the outrageous mitigation expenses.

Problems We Found With Chattanooga's Drinking Water

Analies Dyjak | Policy Nerd   

For Hydroviv’s assessment of Chattanooga, Tennessee’s drinking water quality, we collected water quality test data from the city’s Consumer Confidence Report and the U.S. Environmental Protection Agency. We cross referenced Chattanooga’s water quality data with toxicity studies in scientific and medical literature. The water filters that we sell at Hydroviv are optimized to filter out contaminants that are found in Chattanooga’s drinking water.

Where Does Chattanooga Source Its Drinking Water?

Chattanooga sources its drinking water primarily from the Tennessee River. Water is treated at the Tennessee American Water Citico Water Treatment Plant before being distributed to the 177,000 residents of Chattanooga.

Disinfection Byproducts In Chattanooga’s Drinking Water

In recent years, Chattanooga has had a major problem with disinfection byproducts or DBPs. DBPs form when the chlorine-based disinfectants that are routinely added the water supply, react with organic matter. DBPs are split into two categories; Haloacetic Acids-5 (HAA5) and Total Trihalomethanes (TTHMs). Concentrations of TTHMs averaged 70 parts per billion, but were detected as high as 89.1 parts per billion in Chattanooga water. HAA5 concentrations averaged 41.8 parts per billion and reached levels as high as 51.4 parts per billion. For a bit of perspective, the EPA set a Maximum Contaminant Level of 60 parts per billion for HAA5 and 80 parts per billion for TTHMs. While Chattanooga's water quality is technically still in compliance, these levels are definitely high. Disinfection Byproducts are a category of emerging contaminants which means they have been detected in drinking water but the risk to human health is unknown. Regulatory agencies have very little knowledge about the adverse health effects of DBPs, and their toxicity.

Lead In Chattanooga’s Drinking Water

Lead enters tap water through old lead service pipes and lead-containing plumbing. 10% of sites that were tested for lead had concentrations over 2 parts per billion. Environmental Protection Agency, Center for Disease Control, and American Academy of Pediatrics all recognize that there is no safe level of lead for children. However, this years lead levels in Chattanooga are relatively low compared to other major municipalities in the US.

It’s important to note that only a handful of contaminants are required to be included in annual Consumer Confidence Reports, and that there are hundreds of potentially harmful unregulated contaminants that aren’t accounted for.

Why Does Washington, DC Water Taste Bad Right Now?

Analies Ross-Dyjak | Water Nerd   

Our Water Nerds have received a ton of questions about a noticeable change in the taste and smell of Washington DC's tap water. While we've heard lots of interesting hypotheses, what's really happening is that the Washington Aqueduct (where DC Water purchases water from) has recently switched over its disinfectants from chloramine to chlorine, for an annual "Spring Cleaning" of the distribution lines. DC residents can expect funky-tasting water from March 25-May 6, 2019.

How Are Chloramine and Chlorine Different?

We answer this question in much more detail in a different post, but here's the skinny on chlorine in drinking water: Like a growing number of US cities, Washington, DC uses chloramine as the primary disinfectant for a couple of reasons:
  1. Chloramine persists longer in the distribution system, so it does a better job killing bacteria in areas of the water distribution system that are near the end of the pipes, or don't have as high of flow as other areas.

  2.  It forms fewer disinfection byproducts in the presence of organic matter.

  3.  Chloramine-treated water doesn't have as strong of a taste as chlorine-treated water.

While these are all great reasons to use chloramine, most cities that use chloramine undergo a more aggressive disinfection cycle for a few weeks each year (aka Spring Cleaning).  

What Are The Impacts of Switching to Chlorine?

People often find that the water tastes and smells like pool water during the disinfectant switch, in addition to your bathroom smelling like swimming pool's locker room after showering. If you want to fix this problem... you have a couple of options that don't involve bottled water (horrible for the environment and less regulated than tap water!).
  1.  Get a water filter that's designed to handle it (and lead, chromium 6, VOCs...)!

  2.  If you let chlorinated tap water sit in a pitcher overnight, a good amount of the chlorine taste and smell will go away.  However, many people find that the water tastes "stale" when this happens (from the less volatile disinfection byproducts).

When Will Washington, DC's Water Switch Back Over to Chloramine?

The "Spring Cleaning" period is scheduled to take place from March 25 until May 6, 2019. After May 6, the water utility provider will switch the disinfectant back over to chloramine. Until then... non-Hydroviv users will just have to hold their noses!

Problems We Found In Milwaukee's Drinking Water

Analies Dyjak | Policy Nerd   

For Hydroviv’s assessment of Milwaukee, Wisconsin’s drinking water, we collected water quality test data from the city and the U.S. Environmental Protection Agency. We cross referenced their water quality data with toxicity studies in scientific and medical literature. The water filters that we sell at Hydroviv are optimized to filter out contaminants that are found in Milwaukee’s drinking water.

Where Does Milwaukee Source Its Drinking Water?

Milwaukee sources its drinking water from Lake Michigan. This surface water source has had a long history of pollution, including recent lawsuits involving Chromium 6 releases from an abutting steel facility.  

Chromium 6 In Milwaukee’s Drinking Water

Chromium 6 is a highly toxic metal that is currently unregulated by the EPA. In recent years, Milwaukee has had a major problem with this dangerous contaminant. Chromium 6 pollution is associated with metal processing, tannery facilities, chromate production, stainless steel welding, and pigment production. This years water quality report for Milwaukee detected levels of Chromium 6 as high as 0.2 parts per billion. This concentration is 10 times higher than the concentration determined to have a negligible impact on cancer risk. EPA has acknowledged that Chromium 6 is a known human carcinogen through inhalation, but is still determining its cancer potential through ingestion of drinking water. Lung, nasal and sinus cancers are associated with Chromium 6 exposure. Ingestion of extremely high doses of chromium 6 compounds can cause acute respiratory disease, cardiovascular, gastrointestinal, hematological, hepatic, renal, and neurological distress which may result in death.

Lead In Milwaukee's Drinking Water 

In recent years, Milwaukee has had a problem with lead in drinking water. Lead enters tap water through old lead service pipes and lead-containing plumbing. 10% of sites that were tested for lead had concentrations over 7.2 parts per billion. The highest concentration detected in 2017 was 130 parts per billion, which is a whopping 8.6 times higher that the Federal Action Level of 15 parts per billion. Environmental Protection Agency, Center for Disease Control and American Academy of Pediatrics all recognize that there is no safe level of lead for children. These health and regulatory organizations are trying to reduce the allowable limit to 1 part per billion, so a concentration of 130 parts per billion is of serious concern. Additionally, these measurements may not be a true indication of your tap water if your home has lead plumbing or lead fixtures. Treated water leaving the plant may be in compliance with loose EPA standards, but could become contaminated once it enters older infrastructure. Houses built before 1986 were most likely built with lead plumbing and lead fixtures. Lead exposure can cause developmental issues, lowered IQ, and damages to the kidneys and brain.

Perfluorinated Compounds In Milwaukee's Drinking Water 

This years water quality report for Milwaukee included test data from six Perfluorinated Compounds (PFCs). Perfluorinated Compounds are associated with firefighting foam, non-stick cookware, Scotchguard and other solvents from manufacturing. The two PFCs that are the most well known and the most researched are Perfluorooctanoic acid (PFOA) which was detected at 2.1 parts per trillion and Perfluorooctane-sulfonic acid (PFOS) which was detected at 2 parts per trillion. The Agency for Toxic Substances and Disease Registry recently recommended setting a Minimum Risk Level of 20 parts per trillion for both of these chemicals. These data are preliminary and the effects to human health are still unknown. This category of chemicals are “emerging contaminants” which means they are thought to pose a potential threat to human health and the environment, but haven't yet been regulated. Perfluorinated Compounds contribute to environmental contamination largely due to the fact that they are highly resistant to degradation processes, and thus persist for many years in water, air and can enter the food chain via bioaccumulation in certain animal species.

Chloramine In Norman’s Drinking Water

While most municipalities use chlorine as the primary drinking water disinfectant, Milwaukee’s drinking water is disinfected with chloramine. Chloramine is primarily responsible for what many customers report as the “bad taste” or “pool smell” of tap water. Unlike chlorine, chloramine does not dissipate if a container of water is left in the refrigerator overnight. Most one-size-fits-all water filters use filtration media that doesn’t do a great job removing chloramine, but the filters that we design and build at Hydroviv for Milwaukee use a special filtration media that is purposefully designed to remove chloramine.

It’s important to note that only a handful of contaminants are required to be included in annual Consumer Confidence Reports, and that there are hundreds of potentially harmful unregulated contaminants that aren’t accounted for. If you’re interested in learning more about water filters that have been optimized for Milwaukee’s tap water quality, feel free to visit www.hydroviv.com to talk to a Water Nerd on our live chat feature or send us an email at hello@hydroviv.com.

Problems We Found With Orono/Veazie's Drinking Water

Analies Dyjak | Policy Nerd   

For Hydroviv’s assessment of drinking water quality in Orono, Maine, we collected water quality test data from the most recent Consumer Confidence Report and the U.S. Environmental Protection Agency. We cross referenced water quality data with toxicity studies in scientific and medical literature. The water filters that we sell at Hydroviv are optimized to filter out contaminants that are found in both Orono and Veazie drinking water.

Where Does Orono Source Its Drinking Water?

Orono and Veazie source its drinking water from four groundwater wells located just off of Bennoch Road. Orono-Veazie Water District treats its drinking water with chlorine, fluoride, and sodium hydroxide.

Lead In Orono/Veazie Drinking Water

In recent years, both municipalities have had a major problem with Orono-Veazie water quality, including lead in drinking water. Lead enters tap water through old lead service pipes and lead-containing plumbing. 10% of sites that were tested for lead had concentrations over 3.7 parts per billion. Environmental Protection Agency, Center for Disease Control, and American Academy of Pediatrics all recognize that there is no safe level of lead for children. Treated water leaving the plant may be in compliance with the loose EPA threshold of 15 parts per billion, but could become contaminated once exposed to older infrastructure. Additionally, municipalities are only required to test a handful of homes every few years, so the levels reported in the most recent annual water quality report might not reflect the lead levels in your tap water. Houses built before 1986 were most likely built with lead plumbing and lead fixtures. This is a huge problem for water quality in Orono, Maine because lead exposure can cause developmental issues, lowered IQ, and damages to the kidneys and brain. Orono has historically had high levels of lead in drinking water. For example, in 2012, 10% of samples tested for lead had concentrations over 13 parts per billion.

Disinfection Byproducts In Orono/Veazie Drinking Water

Orono/Veazie municipal water is contaminated with disinfection byproducts or DBPs. DBPs are formed when the chlorine-based disinfectants that are routinely added to the water supply, react with organic material. They are split into two categories: Total Trihalomethanes (TTHMs) and Haloacetic Acids-5 (HAA5). Water samples were collected and tested for DBPs from 1215 State Street and the University of Maine Student Union. Concentrations of HAA5 averaged 9 parts per billion at the State Street location and 33 parts per billion at the UMaine Student Union. Concentrations of TTHMs averaged 64 parts per billion at the State Street location and 36 parts per billion at the UMaine. For a bit of perspective, EPA’s Maximum Contaminant Level is 60 parts per billion for HAA5 and 80 parts per billion for TTHMs. Disinfection Byproducts are a category of emerging contaminants which means they have been detected in drinking water but the risk to human health is unknown. Regulatory agencies have very little knowledge about the adverse health effects of DBPs, and their toxicity. EPA has stated that they have been linked to an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems.

It’s important to note that only a handful of contaminants are required to be included in annual Water Quality Reports, and that there are hundreds of potentially harmful unregulated contaminants that aren’t accounted for.

EPA Proposes New Definition of "Waters of the United States"

Analies Dyjak & Matthew Krug   

February 14th 2019: The Department of the Army and the Environmental Protection Agency  posted the newly proposed “Waters of the United States” rule to the Federal Register. At its core, the proposed EPA WOTUS rule limits the water that EPA can regulate and monitor. By narrowing the scope of WOTUS definitions, this basically gives industries a roadmap of where it’s okay to pollute without the need for permitting. This is a big deal for the 45 million Americans who rely on well water for drinking and bathing. So, why should you care about the definition of waters of the United States?

"Waters of the United States"

This definition, also known as “WOTUS” has been up for debate for decades, and it’s interpretation has seen several Supreme Court cases. This proposed rule determines what waters the federal government is able to regulate and monitor. Generally, “waters” have traditionally been navigable waters such as oceans, rivers, ponds, and streams. As our scientific understanding of hydrology has improved, the scope of what are considered “waters” has expanded.

What Is Not Protected Under The Proposed Rule?

WOTUS definitions name certain waters as “excluded,” which, in this case, means they do not have a surface water connection. This means that groundwater, ephemeral streams, ditches, prior converted cropland and some wetlands and ponds are not included. This is a continued rollback of environmental regulations - and the 2019 EPA WOTUS rule proposal may have the farthest-reaching implications of all.

How Does This Proposed Rule Affect Drinking Water?

This rule puts the 45 million Americans that use private wells as a primary source of drinking water at risk. Private wells are not regulated by federal, state, or local governments, and agencies are not required to test for contaminants or ensure “compliance.” A 2006 study by the USGS concluded that private wells are already contaminated with various types of agricultural runoff, solvents, fumigants and inorganic compounds, the most common being arsenic and nitrates. Arsenic is a naturally occurring organic compound, that enters groundwater as bedrock weathers overtime. However, nitrates are used in fertilizers and enter both surface and groundwater from agricultural runoff. 8.4% of the wells tested in this study were in exceeded the federal standard for nitrates (we have an article dedicated specifically to nitrates in groundwater). Further, EPA does not provide recommended criteria or standards for private well users. By rolling back protections, private well users are being further kept in the dark.

How Did They Arrive At this Rule?

The proposed EPA WOTUS rule is primarily based off a majority opinion by Justice Scalia in the Supreme Court case Rapanos v. United States. Scalia’s interpretation favored “traditional waters,” and steered away from Justice Kennedy’s “significant nexus theory.” In his majority opinion, Scalia wrote that federal protections should cover:

“...only those wetland with a continuous surface connection to bodies that are waters of the United States.”

Who’s Driving?

The American Farm Bureau dominated the conversation at the press conference for the proposed EPA WOTUS rule in early December of 2018. Industries lobbied hard to limit the scope of jurisdictional waters. In a political landscape where there is an abundance of legislation grandfathered in to protect the chemical, fossil fuel, and agricultural industries, it should come as no surprise that the current administration did not break from tradition. The agricultural industry is not the only institution who will benefit from this proposed rule. Chemical manufacturing companies have to go through a rigorous permitting process determined by state or federal governments (NPDES) which regulate pollution. But now, with a clearly defined and reduced scope of what constitutes a water of the United States, these companies are able to map out how to circumvent regulation.

The federal government has designated this as “economically significant”

This means that the proposed rule with have an annual effect on the economy of $100 million or more. 

Our Take:

This proposed WOTUS definitions puts the 15% of the country at further risk of groundwater contamination. This population of people are now on their own in terms of monitoring their drinking water and keeping up with land use changes. Our science team will be submitting public comments on this proposed rule, which will be available on our website in the upcoming weeks. We encourage our readers to do the same thing!
