Low levels of PFAS detected in water system serving Central Maui
Samples collected from Conolidated Baseyards water system wells were found to contain low levels of Perfluorohexane Sulfonic Acid (PFHxS ).
The detections were sporadic, with concentrations ranging from none to 2.2 nanograms per liter.
The positive samples were collected on July 11, 2023, when 2.0 nanograms per liter were detected, and again on March 24 of this year, when 2.2 nanograms per liter were detected. No detections of PFHxS were found on Oct. 5, 2023, and on April 21 of this year.
The U.S. Environmental Protection Agency's maximum contaminant level for PFHxS is 10 nanograms per liter.
PFAS, short for or perfluoroalkyl and polyfluoroalkyl substances, have been used since the 1940s in consumer products such as food packaging, carpets, cookware and other items designed to be waterproof, stain-resistant or nonstick.
They are also a component of firefighting foam, and have many industrial uses.
DOH issued the press release in accordance with state law.

New study makes concerning discovery after testing samples from nearly 200 homes: 'It's a global problem'
New study makes concerning discovery after testing samples from nearly 200 homes: 'It's a global problem' Many people trust private wells to deliver clean, natural water — but a new study reveals that's not always the case. What's happening? A three-year study from Pennsylvania State University found that nearly one in five private wells tested in Pennsylvania contained PFAS — manmade "forever chemicals" linked to serious health problems. According to WESA, the researchers tested 167 private wells across the state and discovered that 18% showed PFAS contamination, with some exceeding federal safety limits. PFAS, or per- and polyfluoroalkyl substances, are a group of long-lasting chemicals often used in products like nonstick cookware, water-resistant clothing, and firefighting foam. They're known to build up in the human body and the environment, and they're now showing up in unexpected places — including people's homes. "It's a global problem that I think researchers as a whole should come together to figure out how to support communities who may be impacted vastly," said Faith Kibuye, a water resources extension specialist at Penn State, per WESA. Why is this finding concerning? Research has linked PFAS exposure to increased risk of cancer, weakened immune systems, hormone disruption, and developmental issues in children. With over 1 million households relying on private wells in Pennsylvania alone — many of which are located in rural or underserved areas — this issue has significant public health implications, WESA reported. Since state and federal water regulations don't cover private wells, homeowners must handle testing and treatment themselves. That makes PFAS contamination an invisible threat — one that families may not realize they're exposed to until it's too late. Unfortunately, this isn't an isolated case. One study revealed that nearly half of the U.S. tap water contains PFAS, and experts in the U.K. have called for tighter regulations on the presence of "forever chemicals" in their drinking water. These stories show just how widespread the problem is becoming. What's being done about PFAS in well water? The researchers hope their work will help spread awareness and prompt more homeowners to test their water. "It's also a good thing that we're getting a lot of awareness out there about PFAS in general and what people can do," Kibuye said, per WESA. In Pennsylvania, homeowners can turn to state-certified labs to test their well water for PFAS. If contamination shows up, filtration systems — like activated carbon or reverse osmosis — can help remove the chemicals. On a larger scale, several states have begun tightening regulations on PFAS use. Last year, the U.S. Environmental Protection Agency finalized nationwide limits for six types of PFAS in public water systems, and it confirmed this spring it intends to uphold those regulations under the new administration. Although current regulations exclude private wells, increasing awareness of the issue could help close that gap and give more families peace of mind about the water they rely on every day.

NYC officials claim worst of Legionnaires' disease outbreak is over — even as top doc says ‘we have more work to do'
The worst of the Legionnaires' disease outbreak that killed three people and sickened several dozen is over, Big Apple officials predicted Thursday – even as the city's top doc acknowledged 'we have more work to do.' At least 24 people remained hospitalized nearly two weeks after the cluster of pneumonia-like illnesses was first detected in Harlem, with five zip codes affected, city health officials said. 'Our expectation is that there's no further bacteria in the air at this point so we can expect the cases to go down,' interim Health Commissioner Dr. Michelle Morse said at a news conference. 3 Cooling towers seen in Harlem amid the Legionnaires' disease outbreak in New York City on Aug. 6, 2025. REUTERS 'This is my top priority right now. Three deaths is unacceptable and we know we have more work to do.' Morse said 11 cooling towers had been scrubbed clean in order to stop the illness from spreading — but city officials wouldn't say which buildings had the troubled structures, arguing they didn't want to give anyone a false sense of security. 'I don't want anyone to be concerned that if they're in one building or another they may be more or less at risk,' Morse said. 'From our perspective, it's really important that everyone in the five zip codes understand that they may be at risk.' The areas where cases have been confirmed are in five Harlem zip codes: 10027, 10030, 10035, 10037, and 10039, along with the bordering communities, according to the city Department of Health. DOH officials said there were 81 confirmed as of Thursday – a slight uptick from the previous day. 3 A map of the initial Legionnaire's disease outbreak in New York City. People can catch Legionnaires' disease from bacterial droplets that come from water systems like cooling towers and are breathed in. It can take between 12 to 14 days from exposure to the droplets to start feeling sick, according to Morse. The disease isn't spread person-to-person, she noted. Morse cautioned people for now should remain vigilant if they start feeling sick, though she stressed the city has treated the cooling towers that tested positive for Legionella bacteria. Local elected officials on hand in front of the Adam Clayton Powell statue urged Harlem residents to seek medical help if they are beginning to feel under the weather. The illness can be treatable if caught early enough. 'This is not the time to say, let me just go to the grocery store and get some ginger ale and let me lay up somewhere,' Councilman Yusef Salaam said. 'This is the time for you to actually go and seek medical attention. That's how serious this is.' State Sen. Cordell Cleare, who represents the neighborhood, introduced legislation on Wednesday in hopes of limiting cases going forward. She wants cooling towers inspected twice a year instead of once and building owners to tackle detected maintenance problem within 24 hours instead of a 48-hour timeframe. 'Building maintenance shouldn't cost people their lives,' Cleare told The Post Thursday. 3 According to city health officials, the worst of the Legionnaires' disease outbreak is over. REUTERS 'Three deaths, one death is too many' the pol said at the press conference, adding, 'one of the things that's very important for us to do is examine and find out why this keeps popping up in black and brown communities.' Cleare also said she wants clarity on where the 11 troubled cooling towers are located in the area, but city officials haven't provided that information to her. City officials said they aren't identifying exact buildings because the issue is in the air — which could affect a wider area — and is not in the water of the buildings. The buildings' water is safe to bathe and cook with, the officials added.
