PFAS in Drinking Water: What You Need To Know About PFAS In Groundwater

Do you live in a city that has a water supply with high levels of certain chemicals? Are you curious about what substances are present in your drinking water? This article gives an overview of how the EPA tests for and evaluates contaminants in groundwater.

When the science community encourages dialogue, it becomes more effective! In this article, Nene Adams looks at Good Chemicals Sciences’ recent interactive debate between two leading scientists on the risks of PFAS and groundwater contamination.

What is PFAS?

PFAS chemicals are manmade and have been used in manufacturing for years. They’re now being found in drinking water supplies around the country. Here’s what you need to know about PFAS in groundwater:

What are PFAS chemicals?

Pfas chemicals are manmade and have been used in manufacturing for years. They’re now being found in drinking water supplies around the country.

Where are PFAS found? 

PFAS chemicals are widely used in manufacturing, including making Teflon, leather tanning fluids, and other products. The substances have also been used in firefighting foam, road de-icing processes, and military fire protective clothing. As a result, they’ve been found across the U.S., Canada, Europe, Asia, and Australia. 

How does PFAS get into groundwater? 

Pfas can leach from land or wastewater treatment plants into bodies of water like rivers or aquifers where people drink or use the water for irrigation. Once inside groundwater systems, Pfas can bioaccumulate (build up) over time as they move through soil and underground rocks until they reach freshwater sources like rivers or lakes. 

What health effects does PFAS exposure cause? 

There is still much we don’t know about the health effects of long-term exposure to PFAS chemicals. However, there is evidence that PFAS can cause cancer

What is PFAS in Drinking Water?

PFAS are a family of chemicals that have been used for decades in many products, including paper, food packaging, clothing, and carpeting. They are also found in the environment, where they can be released into the air and water.

In 2017, PFAS were identified as a potential health hazard after it was revealed that they can increase the risk of cancer and other diseases. Because PFAS can persist in the environment for a long time, drinking water sources that contain them may continue to expose people to these chemicals for years or even decades.

To help protect people from these exposures, public health officials have recommended drinking water with lower levels of PFAS. EPA has established a safe level of 0.7 parts per trillion (ppt) for total PFAS in drinking water. While this level is protective for most people, it’s still possible to exceed it if your municipality uses highly contaminated sources of water or if you drink large amounts of affected water each day. In both cases, consuming high levels of PFAS can lead to serious health problems.

If you’re concerned about the PFAS levels in the water source, you should talk to your doctor or local public health agency. They can help you determine whether any changes are necessary for your diet or lifestyle to reduce your exposure to these chemicals.

How is it Contaminated and Found in the Water?

PFAS are persistent, long-lived chemicals that have been found in numerous types of water and soil. They can enter the environment from a variety of sources, including landfills, manufacturing processes, and burning fuels.PFAS have been linked to health problems such as cancer and developmental problems in children.

The three main types of PFAS are PFOA (perfluorooctanoic acid), PFCs (perfluorocarbon compounds), and PFOS (perfluorobutane sulfonate).PFOA is especially worry

What’s Going on with EPA & Pfas in Drinking Water?

PFAS are substances that have been used in a variety of products, including water repellents and packaging materials. As these substances have become more widespread, their presence in groundwater has come under increased scrutiny.

In March of this year, the Environmental Protection Agency (EPA) announced that it was starting to investigate whether PFAS may be present in drinking water sources across the U.S. The EPA is working with states and tribes to collect data on PFAS levels as well as assess health and environmental impacts.

The EPA’s investigation could result in nationwide regulation of PFAS in drinking water. States that currently have high levels of PFAS may need to take action to lower them, such as by using alternative chemicals or filtering out the compounds.

While the exact impact of PFAS on human health remains unknown, the EPA says there is evidence that they can disrupt thyroid function and lead to other problems like developmental delays and increased cancer risk. For these reasons, the agency is urging people to avoid drinking contaminated water and to talk with their doctor if they have any concerns about their health.

Is PFAS in drinking water a problem?

PFASs (perfluorinated alkyl substances) are man-made chemicals that have been linked to cancer and other diseases. In recent years, there has been growing concern about PFAS in drinking water. Pfas are found in many products, including firefighting foams, insulation, and clothing. They can also leach into groundwater from landfills or other sources. 

What is the extent of the problem with PFASs in drinking water?

There is evidence thatPFASs may be leaking from some public water systems where they have been used for years. Studies have also shown that people living near military bases or major production facilities have higher levels of PFASs in their blood. And research shows that humans can uptake these substances from the environment and take them into their bodies. 

How do you know if your tap water is contaminated with PFASs?

There is no definitive test for detecting PFAS contamination in water. However, scientists at the Massachusetts Department of Environmental Protection recommend looking for two signs that your water might be contaminated: elevated levels of PFOS or PFOA toxins, and decreases in the number of aerobic bacteria colonies. 

If you think your drinking water is contaminated with PFAS, what should you do?

The first step is to consult a trusted professional who can help you determine if your tap water is safe to drink and

Tips to Safeguard Your Tap Water

If you’re concerned about potential exposures to PFASs in your drinking water, there are a few things you can do to safeguard yourself. First, don’t drink water from municipal sources that have been treated with PFAS-containing chemicals. Second, avoid consuming foods that have been wrapped in materials made with PFAS-containing materials (for example plastics or paper). Finally, keep an eye on the levels of PFAS in your tap water and make sure they stay below the safety limit set by the U.S. Environmental Protection Agency (EPA). Here are some tips to help you stay safe: 

1) Don’t drink water from municipal sources that have been treated with PFAS-containing chemicals. If you must drink water from these sources, make sure to filter it through a filter designed for lead and other contaminants.

2) Avoid eating foods that have been wrapped in materials made with PFAS-containing materials (for example plastics or paper). This includes microwave popcorn bags and products packed in plastic containers.

3) Monitor the levels of PFAS in your tap water. If the levels of these compounds rise above the safety limit set by EPA, managing them may require using filtered or bottled water.
