Scientists in rural New England are working to better monitor and manage tick populations as climate change helps fuel their dramatic increase.

Cases of tick-borne illnesses have skyrocketed in the region, while new tick species have expanded their range further north, posing risks to both humans and wildlife.

University of New Hampshire Clinical Associate Professor David Needle said scientists will collaborate on data collection as well as education and public outreach on how to stay safe.

"General thought is," said Needle, "the number of cases and impacts from tick-borne diseases are grossly underestimated by what we actually see and what's been tested."

Needle said the data collected could also serve as a warning system for farmers and vets to better protect livestock by knowing when to utilize protective chemicals, potentially saving not only the animals lives but preventing financial losses for rural communities.

Increasingly mild winters in New England have helped ticks to thrive at a time when they are normally dormant. And that is altering the regional ecosystem - causing a dramatic die-off of moose calves, for example.

Needle said as tick populations increase, scientists need to better understand their patterns and where diseases could emerge next in both wildlife and humans.

"At the very least," said Needle, "we're going to be generating data and real information about where pathogens are and where ticks are and the data will hopefully provide opportunity for intervention at the public health level."

The two-year project involves scientists with the Universities of Maine, New Hampshire and Vermont. Needle said he hopes the data can provide a baseline for scientists to follow in the future.

United Nations experts are raising concerns about chemical giants DuPont and Chemours, saying they've violated human rights in North Carolina.

At a virtual news conference this week, a UN representative said these companies have been releasing harmful PFAS chemicals into the environment near the lower Cape Fear River.

Emily Donovan, co-founder of the group Clean Cape Fear, said more than 300 different chemicals in their water led them to seek help from the UN. She said getting clean and safe drinking water has been an issue for decades, and local residents continue to suffer the consequences.

"The amount of sicknesses and illnesses happening in our region is incredibly depressing and hurtful," said Donovan.

Last fall, she said, the UN wrote to the companies expressing concern. In their responses, DuPont denied responsibility for a Fayetteville Works Plant, a suspected contamination source, and Chemours claimed it has reduced its PFAS releases and exposure.

Donovan said they're still figuring out how widespread the pollution is. They know it affects eight counties, about a half-million people and around 10,000 wells. With Chemours planning an expansion and perhaps even importing international waste, she said the situation is becoming dire for local communities.

"We are tired of being a sacrifice zone," she added.

Dr. Marcos Orellana, special rapporteur on toxics and human rights for the United Nations, warns that PFAS chemicals are a danger worldwide. He criticized companies that refuse to acknowledge the potential dangers and don't do more to protect residents.

"The concerns in regards to Cape Fear and the Fayetteville Works are extremely concerning," he said, "because of disinformation spread by companies, because of the dumping and pollution, inadequate controls that have affected people's access to clean drinking water."

The letter called on the companies to take action to prevent PFAS exposure and protect local residents. The UN has also contacted state and federal regulators, demanding that they seek greater accountability from polluters. Orellana said the U.S. government has yet to respond.

Spokane has joined a lawsuit against the manufacturers of toxic chemicals known as PFAS after the discovery of the chemicals in parts of the city's drinking water.

PFAS, also known as forever chemicals, are linked to cancer and other health effects and have been found at high levels in the West Plains near Spokane International Airport.

Chuck Danner lives in the area and said a test found he had twice the average rate of the chemicals in his blood. He stopped drinking water from his well and noted the body metabolizes the chemicals eventually.

"But it takes up to 40 years to metabolize one of the chemicals out of your body, and it's a lengthy thing," Danner pointed out. "I won't live that long, so it's going to be with me forever."

Danner argued the PFAS crisis has hurt his property value and caused him mental anguish. He added his daughter has thyroid disease, which could be connected to PFAS in his water well. The organization West Plains Water Coalition has been working to bring justice for community members.

The PFAS came from firefighting foam used at the Spokane airport.

Jeff DeBray, eastern Washington director for the progressive group Fuse Washington, said the airport and West Plains are in part of the city represented by Commissioner Al French, who served on the Airport Board. DeBray emphasized the commissioner initially put roadblocks in the way of investigating this issue.

"We're interested in protecting public health for people, and immediately to me that is centered around accountability," DeBray asserted. "We have a basic expectation that our public officials will be invested in protecting the health of citizens."

In response, French said it is a national issue and he has been working alongside state and federal governments to unveil a solution this week. He also noted the U.S. Environmental Protection Agency only recently unveiled a PFAS water standard.

Danner said he expects a response to rectify the issue.

"I would like to see them accept responsibility and be held accountable for what has taken place," Danner stressed. "The least of that would be to provide a filter system for my well and/or clean drinking water."

Marylanders shopping for fresh produce may want to consider a new report that finds chemical residues in much of the crop. In its 2024 "Shoppers Guide to Pesticides in Produce," the nonprofit Environmental Working Group found residue of potentially harmful pesticides on 75% of all conventionally grown produce tested.

The group relied on data from the U.S. Department of Agriculture and the Food and Drug Administration, which tested more than 47,000 samples of 46 different fruits and vegetables.

Alexa Friedman, senior scientist for the Environmental Working Group, said pesticides have been linked to a number of health problems.

"Things like cardio metabolic disorders, different types of diabetes, as well as some cancers," Friedman outlined. "If you are exposed to multiple pesticides over the course of a lifetime, they might lead to a greater risk in any of these health outcomes."

Many of the fruits and vegetables were washed and peeled prior to testing. Nonorganic strawberries were found to be the most contaminated item. The state of Maryland has more than 12,000 farms but as of 2022, only 62 farms in the state were certified organic.

The Shoppers Guide features a Dirty Dozen list of the most contaminated fruits and vegetables. It includes spinach, kale, grapes and peaches. There's also a Clean Fifteen list of conventionally grown produce found to be low in pesticide contamination, including avocados, papaya, mangos and carrots.

Friedman emphasized they encourage people to buy organic when possible.

"We always recommend continuing to consume fruits and vegetables, and up your fruit and vegetable intake," Friedman noted. "If you are interested in purchasing organic versions of the produce that's on the Dirty Dozen, there are also some more budget-friendly options in the frozen aisles."

In addition to pesticides, the report found high concentrations of fungicides, which are used to avoid such diseases as powdery mildew and are also applied to harvested produce to prevent mold. The report said fungicides are less studied than other pesticides but emerging evidence suggests some may disrupt hormone systems in the body. While the quantities of pesticides detected are within allowed amounts, Friedman stressed people should still be cautious.

"Even if the amount of pesticides are within legal limits on these produce, it doesn't mean it's safe for everyone, particularly susceptible populations like children," Friedman cautioned.
