In a new study, researchers from North Carolina State University detected elevated PFAS levels in the blood of pet dogs and horses from Gray’s Creek, N.C.—including dogs that only drank bottled water. The work establishes horses as an important sentinel species and is a step toward investigating connections between PFAS exposure and liver and kidney function in dogs and horses.

The study included 31 dogs and 32 horses from the community, and was conducted at the behest of community members concerned about their pets’ well-being. All of the households in the study were on well water, and all of the wells had been tested and deemed PFAS contaminated by state inspectors.

The animals received a general veterinary health check and had their blood serum screened for 33 different PFAS chemicals. These PFAS were chosen based on compounds that were present in the Cape Fear River basin and the availability of analytical standards.

From the targeted list of 33 PFAS of interest, researchers found 20 different PFAS in the animals. All of the animals in the study had at least one chemical detected in their blood serum, and over 50% of the dogs and horses had at least 12 of the 20 detected PFAS.

PFOS, a long-chain PFAS used for years in industrial and commercial products, had the highest concentrations in dog serum. The perfluorosulfonic acid PFHxS, a surfactant used in consumer products and firefighting foams, was detected in dogs, but not horses. Consistent with wells being the known contamination source, some ether-containing PFAS including HFPO-DA (colloquially known as GenX), were detected only in dogs and horses that drank well water.

In dogs who drank well water, median concentrations of two of the PFAS—PFOS and PFHxS –were similar to those of children in the Wilmington GenX exposure study, suggesting that pet dogs may serve as an important indicator of household PFAS. Dogs who drank bottled water, on the other hand, had different types of PFAS in their blood serum. However, 16 out of the 20 PFAS detected in this study were found in the dogs who drank bottled water.

Overall, horses had lower concentrations of PFAS than dogs, though the horses did show higher concentrations of Nafion byproduct 2 (NBP2), a byproduct of fluorochemical manufacturing. The finding suggests that contamination of the outdoor environment, potentially from deposition of the PFAS onto forage, contributed to their exposure.

“Horses have not previously been used to monitor PFAS exposure,” says Kylie Rock, postdoctoral researcher at NC State and first author of the work. “But they may provide critical information about routes of exposure from the outdoor environment when they reside in close proximity to known contamination sources.”

Finally, the veterinary blood chemistry panels for the animals showed changes in diagnostic biomarkers used to assess liver and kidney dysfunction, two organ systems that are primary targets of PFAS toxicity in humans.

“While the exposures that we found were generally low, we did see differences in concentration and composition for animals that live indoors versus outside,” says Scott Belcher, associate professor of biology at NC State and corresponding author of the work.

“The fact that some of the concentrations in dogs are similar to those in children reinforces the fact that dogs are important in-home sentinels for these contaminants,” Belcher says. “And the fact that PFAS is still present in animals that don’t drink well water points to other sources of contamination within homes, such as household dust or food.”

The work, title “Domestic Dogs and Horses as Sentinels of Per- and Polyfluoroalkyl Substance (PFAS) Exposure and Associated Health Biomarkers in Gray’s Creek North Carolina,” appears in Environmental Science and Technology.

Tropical Depression Four forms on its way to the Gulf of Mexico

Tropical Depression Four forms on its way to the Gulf of Mexico


As of the 5 AM update Friday, Tropical Depression Four has formed. Areas along the East Coast including North Carolina need to continue monitoring this system. Winds are at 30 MPH and gusts are up to 40 MPH. The pressure dropped to 1009 mb and is moving to the west at 16 mph. TD 4 is expected to become Tropical Storm Debby over the weekend. Tuesday night and Wednesday are First Alert Weather Days due to the threat to ENC from this system but we may need to adjust the timing as we get closer.

The latest advisory from the National Hurricane Center continues to show ENC in the cone of uncertainty.(WITN)

It’ll move slowly before escaping to the north next week. As it moves up the East Coast, there’s a lot more uncertainty about the track and threats. We expect the track of this system to change through the weekend and even into next week. If ENC sees impacts from this system, they’d likely come mid-week. The longer this system stays over land, the weaker it’ll be. It’ll have the chance to strengthen if it moves back over open water, especially if it moves over the warm waters of the Gulf Stream.

Storms are possible Saturday through Monday as a developing tropical system gets closer.

The speed of this system is just as important as the strength. The quicker it moves through, the less rain piles up. If it slows down or stalls, higher rainfall amounts would be expected. Our river levels have dropped a bit since July’s wet weather, but levels are still higher than what you’d find in a typical August.

This is a reminder that we are heading into the heart of the hurricane season and to make sure your emergency supplies are ready.

Stay with WITN and WITN.com as we continue to track this system over the coming days and monitor the 2024 Atlantic hurricane season.

Alabama man on work trip stops to buy  quick pick Powerball ticket, wins 6-figure jackpot



Christopher Baker of Leesburg, Alabama was on a work trip in Hickory, North Carolina, when he thought he’d try his luck on a lotto game. It turned out to be a lucrative Powerball win.

An Alabama man on a work trip in North Carolina bought a $3 Quick Pick Powerball ticket on a whim and walked away with a six-figure windfall.

Christopher Baker of Leesburg in northeastern Alabama bought his lucky ticket in July in Hickory, North Carolina, where had been traveling for work, according to Powerball.

When the numbers were drawn, Baker says he had to do a double-take when he realized he had a $100,000 winning ticket. He had matched four white balls and the red Powerball, which would have been $50,000, but a 2X multiplier doubled the win and the disbelief.

“I just kept looking at it to make sure I was reading it right,” he laughed, according to Powerball. “I told my family but they didn’t believe me. either.”

Baker, who called his win “a shocker.” said he plans to save his winnings to buy a house.

Baker will take home $71,501 after federal and state taxes are withheld.

How to play the Powerball

In order to purchase a $2 Powerball ticket, you’ll have to visit your local convenience store, gas station or grocery store − and in a handful of states, you can purchase tickets online.

To play, you will need to pick six numbers in total to mark on your ticket. Five numbers will be white balls ranging from numbers 1 to 69. The Powerball is red and one number which is between 1 and 26.

If you want to increase your chances of winning, you can add a “Power Play” for $1 which increases the winnings for all non-jackpot prizes. This addition can multiply winnings by 2X3X, 4X5X, or 10X.

Players can also ask a cashier for a “Quick Pick” where a cashier will give you a computer generated numbers on a printed Powerball ticket.

Drawings are held on Monday, Wednesday and Saturday nights. If there’s no jackpot winner, the cash prize will increase by millions.
