Awareness of PFAS (Per- and Polyfluoroalkyl Substances) at just 5% for those who know the content. Approximately 27% want to test water safety with numerical values.
NEXER Co., Ltd. and Hiyoshi Corporation conducted a nationwide survey of 500 men and women regarding PFAS. Only 5% fully understood PFAS content, while 77.8% had never heard of it. However, about 27% expressed interest in testing their water's safety if numerical confirmation were possible, indicating potential demand for Hiyoshi Online Inspection Web.

## Survey on PFAS (Per- and Polyfluoroalkyl Substances)
PFAS (Per- and Polyfluoroalkyl Substances) are chemical substances with water and oil repellent properties, used in various industrial fields. Examples include semiconductors, electrical and electronic devices, medical devices, energy, transportation equipment, construction, and infrastructure.
However, in recent years, cases of PFAS detection in tap water, rivers, and well water have been reported.
Because water is essential for daily life, its safety is a concern.
So, how widely known are the term PFAS and its contents to the general public?
Therefore, in collaboration with Hiyoshi Corporation, we conducted a nationwide survey targeting 500 men and women regarding "PFAS (Per- and Polyfluoroalkyl Substances)."

### "Survey on PFAS (Per- and Polyfluoroalkyl Substances)" Survey Overview
- Survey Method: Internet questionnaire
- Survey Period: April 15, 2026 - April 23, 2026
- Respondents: Men and women nationwide
- Valid Responses: 500 samples
- Questions:
- Question 1: Have you recently heard the term "PFAS (Per- and Polyfluoroalkyl Substances)" in news, etc.?
- Question 2: Do you currently feel anxious about drinking or cooking with your home's water as it is?
- Question 3: What specifically are you concerned about?
- Question 4: How do you currently drink water?
- Question 5: Did you know that there is a way to easily order a test online to check if your home's water contains PFAS?
- Question 6: If you could confirm the "safety of your home's water" with numerical values, would you like to do it?
- Question 7: What are your reasons for wanting to do the test?
*As a general rule, percentages are rounded to the nearest second decimal place, so the total may not always be 100%.
### 77.8% responded that they had "never heard of" PFAS
First, we asked about the public awareness of the term PFAS itself.
The most common response was "never heard of it" at 77.8%.
This was followed by "only heard the name" at 17.2%, and "hear it often and know its content" was only 5.0%.
Although opportunities for media coverage are increasing, the results show that only a very small number of people understand its content. The current situation, where even including those who recognize PFAS, only about 20% are aware, indicates that it has not yet been taken as a personal matter.
### 33.6% responded that they "have concerns" about their home's water
Next, we asked if people currently feel anxious about drinking or cooking with their home's water as it is.
"Very anxious" was 8.6%, and "somewhat anxious" was 25.0%, for a total of 33.6% of people feeling some anxiety about their home's water. On the other hand, 66.4% responded "not very concerned," indicating that many people do not have major anxieties about their daily water.
We also asked what specifically concerns them, and some responses are introduced below.
#### What specifically are you concerned about?
- Chlorine and chemical substances. (Male, 20s)
- Once it enters the body, it doesn't leave. Concerned about what effects it has. (Female, 30s)
- High concentrations of PFAS have been detected in nearby areas, so I'm concerned if it's mixed into tap water. (Male, 40s)
- The water pipes seem quite corroded and deteriorated, so harmful substances might be mixed in. (Female, 40s)
Among the voices received, concerns about chemical and harmful substances, as well as opinions about the aging of water pipes, were prominent. There were also concerns about long-term health effects, such as "once it enters the body, it doesn't leave."
Some respondents cited specific cases of high concentrations of PFAS being detected nearby, indicating that news reports and local topics are directly connected to daily anxieties.
### 46.0% responded that they drink their home's water "as is (or boiled)"
So, how do people actually drink water on a daily basis?
We asked about current water drinking habits.
The most common response was "drink home water as is (or boiled)" at 46.0%.
Nearly half of the people were found to be drinking tap water or well water without special treatment.
Next, "drink water passed through a water purifier (faucet type, pot type, etc.)" was 20.6%.
