Pfas, unlimited drinking water in the US to save millions

By knl9j Apr16,2024

The United States government has taken a significant step toward protecting public health in the United States by

passing the first federal law that establishes stringent limitations for the presence of hazardous chemical compounds in drinking water. This is a historic move. This measure, which has received strong support from the scientific community as well as from a variety of environmental associations, has the objective of lowering the population’s exposure to Pfas, which are substances that are per- and polyfluoroalkyl. These substances are also referred to as “eternal pollutants” due to their ability to remain in the environment for an extended period of time and their association with health risks that include cancer.

A new regulation for the levels of per- and polyfluoroalkyl substances (PFAS) in drinking water has been established by the Environmental Protection Agency (EPA), which has reduced the maximum permissible threshold from 70 to 4 parts per trillion (ppt). The increased worry about the potentially detrimental consequences of these chemicals has resulted in a considerable change.

Monitoring the presence of five different forms of PFAS in drinking water is going to be required by the new regulatory framework, which will be implemented by local authorities and water service providers. Within the next three years, they will be required to finish their examinations, and if the limitations that have been established are exceeded, they will be required to install specific filtration systems for the removal of PFAS within the next two years.

Pfas are synthetic compounds that are used in a variety of common items, ranging from personal hygiene to cooking. These chemicals constitute a concern to public health due to the fact that they remain in the environment for an extended period of time and have the ability to cause adverse consequences. A number of studies have demonstrated that Pfas are linked to an increased chance of developing malignancies, as well as reproductive, cardiovascular, and thyroid issues, in addition to liver illness.

According to the Environmental Working Group, more than 200 million people in the United States are exposed to drinking water that is contaminated with PFAS. This is a problem that is also affecting other regions of the world. It has been confirmed by the Centers for Disease Control and Prevention that these compounds are pervasively present in the blood of people living in the United States.

Experts, such as David Andrews of the Environmental Working Group, who describes the establishment of a new norm as “historic,” have expressed their enthusiastic support for the new standard. By establishing a firm commitment to tackling the detrimental impacts of these developing pollutants, this legislative development represents a significant step towards preserving public health and ensuring that drinking water is safe to consume.

Concerning the protection and prevention of public health, the United States has recently implemented new criteria for drinking water.
As we have just seen, the presence of six molecules belonging to the Pfas group, which is comprised of poly- and perfluoroalkyl compounds, in drinking water is linked to a variety of health issues. The Environmental Protection Agency (EPA) has established a limit for two of these compounds, PFOA (which is known to be a human carcinogen) and PFOS (which has the potential to be a carcinogen). During the next few years, the United States government agency anticipates that the implementation of this provision will limit the exposure of about one hundred million people to PFAS in drinking water. This will result in the prevention of thousands of fatalities that may have been caused by these dangerous substances.

Historically significant investments made to safeguard drinking water against the presence of Pfas
The Environmental Protection Agency (EPA) has lately established extremely low limitations not just for Pfos and Pfoa, but also for Pfhxs, Pfna, and Hfpo-da, together referred to as GenX Chemicals. In addition, limitations have been defined for combinations that contain two or more of these three latter PFASs, as well as PFBS, which has supplanted PFOS in a variety of industrial applications over the course of the years. This action is an essential component of the PFAS Strategic Roadmap that the EPA has developed.

With the goal of addressing the issue of persistent pollutants, the administration of Vice President Joe Biden has committed an unprecedented nine billion dollars. When it comes to addressing the issue of drinking water pollution caused by PFAS and other developing toxins, these monies will be utilized to provide assistance to communities. A further twelve billion dollars, which are meant for the general improvement of the quality of drinking water, including the fight against new generation PFAS, must be contributed to this total amount.

Vice President Joe Biden has made the elimination of perfluoroalkyl substances (PFAS) a high priority, and he has committed an unprecedented amount of resources to the fight against these hazardous chemicals and to protect communities all throughout the country. EPA Administrator Michael Regan characterized this initiative as an urgent necessity in order to put a stop to the prolonged suffering that communities have endured as a result of drinking water that is contaminated with PFAS.

Having an impact on the economy and presenting difficulties in the United States’ drinking water infrastructure
It is anticipated by specialists that the new standard will be of particular benefit to areas in the United States that have inadequate infrastructure for the provision of drinking water, but which will have a difficult time affording the expenditures of the monitoring, treatment, and purification systems that are mandated by the rule.

It is estimated by the Environmental Protection Agency (EPA) that water utilities will incur yearly expenses of up to $1.5 billion in order to comply with federal laws. On the other hand, other industry groups believe that the costs to monitor and remove PFAS might exceed $3.2 billion annually.

Brandon Farris, vice president for energy policy at the Association of United States Manufacturers, emphasized in a letter to the Environmental Protection Agency (EPA) that the law requires financial resources that are beyond the capability of enterprises and public water systems that have infrastructure that is getting on in years. Since environmental rules in other countries are less stringent than those in the United States, this raises the possibility that manufacturing of essential compounds could be moved to other countries.

After being passed in 2021, the infrastructure bill that was supported by all parties included $9 billion in funds to address the issue of PFAS contamination. In order to provide assistance to states during the initial stages of examination and treatment, the Environmental Protection Agency (EPA) has directed that one billion dollars of these funds be allocated. In the United States, there are around 6–10% of the 66,000 public water systems that have levels of contamination that are considered to be dangerous.
