Whereas a dairy farm in Fairfield has had its merchandise taken off the cabinets since June following the invention of excessive ranges of so-called “perpetually chemical substances” in its milk, a close-by resident says she not too long ago discovered her properly water has been contaminated with the identical chemical substances.
A take a look at carried out by the Division of Agriculture, Conservation and Forestry discovered that milk from Tozier Dairy Farm, situated on the Ohio Hill Street, had ranges of perfluorooctanesulfonic acid, also referred to as PFOS, that had been larger than the restrict of 210 elements per trillion set by the state.
And after the Division of Environmental Safety carried out a take a look at in September of the properly water on Jerri-Lee Cookson’s property three miles away on the identical highway, officers found that Cookson’s water additionally contained such excessive ranges of PFOS and perfluorooctanoic acid, PFOA, that she was suggested to cease consuming it.
The contaminated milk was found through the division’s second spherical of retail milk testing in February, in keeping with Nancy McBrady, director of the bureau of agriculture.
“There was a outcome for a retailer that was about 60 elements per trillion, we retested it, it was confirmed … and we then labored with that retailer to see what producers had been in that pattern,” McBrady throughout a telephone interview Monday. “And so by working with the retailer, we narrowed it right down to a few potential sources and we examined these sources and that’s how we discovered the Tozier Farm.”
Whereas the investigation into the Tozier Farm is ongoing, Jerri-Lee Cookson, 65, has been suggested by the DEP to not drink the water from the personal properly on her property.
Cookson, who has lived in her dwelling on the Ohio Hill Street for round 12-years, was contacted by DEP in September and was advised that the division was investigating a contamination close by “I received a telephone name out of the blue from DEP,” Cookson stated. “It stated that they needed to check my water as a result of they’d purpose to imagine there was contamination.”
Cookson additionally acquired a letter from DEP that was dated Sept. 18.
“The division is at present conducting an environmental investigation within the space,” the letter learn. “And our current part within the investigation consists of sampling residential water provides in your neighborhood for sure environmental contaminants.”
Per- and polyfluoroalkyl substances, the group of artificial “perpetually chemical substances” identified collectively as PFAS, has a restrict of 70 elements per trillion in consuming water, set by the U.S. Division of Environmental Safety. PFOS and PFOA are two artificial chemical substances which might be known as perfluoroalkyl substances, or PFAS for brief.
In keeping with the DEP’s outcomes dated Oct. 9, Cookson’s water contained ranges of PFOA at 394 elements per trillion and PFOS at 170 elements per trillion.
“It’s undrinkable,” Cookson stated. “I’ve to purchase my water now. I can take a bathe with it however I can’t use it for cooking or watering the backyard.”
State officers couldn’t verify Tuesday whether or not the contamination on the Tozier Farm is instantly linked to the contamination of Cookson’s properly.
“I’ve a variety of questions however I’m not getting many solutions,” Cookson stated. “I must know what I must do on this finish right here. I’ve been consuming this water with these chemical substances for thus lengthy and now abruptly, I can’t drink it.”
Milk with PFOS ranges of 210 elements per trillion or larger are prohibited from being bought commercially. After tracing the contamination again to the Tozier Farm, DACF examined the milk three extra occasions which yielded outcomes of 12,700; 14,900; and 32,200 elements per trillion.
Merchandise from the Tozier Farm had been pulled off cabinets in June and regardless of the excessive numbers of chemical substances within the milk, in July state officers stated that the general public was not in danger due to how diluted the farm’s contribution to the milk pattern was.
“Retail samples are a conglomeration of heaps and many producers, so there’s a dilution issue,” McBrady stated. “The Toziers are a really small farm, (with) fewer than 50 cattle had been being milked at anyone time. In order that they actually had been I feel lower than 1% of the milk that was being contributed to the retailer. So the truth that they had been lower than 1% and the remainder of the 99% was coming from sources that didn’t have this PFOS contamination. And, the pattern they contributed there was sufficient of a dilution that though their numbers had been terribly excessive, the milk that was being consumed was at a stage that was properly under the state restrict.”
PFAS had been developed within the Forties and have become extensively in style in family use for the chemical substances skills to withstand water, stains and grease. These chemical substances had been used merchandise comparable to carpeting, material, clothes, meals packaging, pots and pans in addition to in firefighting foams used on army bases, airports and firefighting coaching services.
The chemical substances have been dubbed “perpetually chemical substances” as a result of their bond is so sturdy, they don’t simply break down within the setting or within the physique.
In keeping with truth sheet from the Maine Division of Well being and Human Providers, nearly everybody has some stage of those chemical substances of their our bodies.
Research of those chemical substances have proven that publicity could cause well being points comparable to elevated ldl cholesterol, thyroid illness, harm to the liver and kidneys, results on fertility and low start weight.
Different research have proven hyperlinks to PFAS and the elevated threat of sure cancers.
“The unlucky factor is PFAS chemical substances find yourself in our waste water streams due to all the merchandise that include PFOS and PFOA have been utilized for a lot of many years … so we have now many years price of these things that has been put down drains and ended up in our septic programs and ended up in our waste water remedy programs,” McBrady stated.
“So right here we’re many many years later lastly understanding that these are very sturdy chemical substances that don’t degrade, that’s why they’re referred to as perpetually chemical substances, and analysis is rising that there could also be well being impacts attributable to them,” he continued. “And there may be analysis as properly that’s demonstrating that these chemical substances not solely keep round however they bind themselves to no matter is grown within the soils or that’s within the water that’s then consumed by an animal or a human.”
The excessive ranges of PFOS within the milk from the Tozier Farm is most definitely attributable to using sludge for agricultural functions, in keeping with McBrady.
“Tright here is a longtime historical past of the licensed utility of sludges on the Tozier Farm,” McBrady stated. “So that actually does seem like a significant factor when accounting for this contamination that’s been discovered on the farm.”
Sludge is handled wastewater solids that may be unfold on soil as an alternative of utilizing fertilizer. In keeping with McBrady, using sludge is an permitted methodology in Maine and different states and may have natural advantages.
David Madore, appearing commissioner for the DEP, stated that the investigation into the farm contamination is way from over.
“At the moment, the Division continues to analyze the noticed ranges of PFAS compounds within the consuming water provide each at 407 Ohio Hill Street and at different properties on this neighborhood,” stated Madore in an e mail Tuesday evening. “Since we’re within the midst of an ongoing investigation, it could be untimely to definitively state what the supply of the exceedance of the EPA Well being Advisory is.”
Madore stated the early samples within the investigation got here from testing the soil within the fields close to the farm, testing feed shares for the herd, testing manure and testing floor water utilized by the farm to water the herd.
In keeping with Madore, the DEP has now been testing wells it suspects is likely to be vulnerable to contamination based mostly on the data gathered within the investigation’s conceptual website mannequin.
“The residential wells examined signify ones recognized as being at best potential threat based mostly on our present CSM (conceptual website mannequin,)” Madore stated. “From these outcomes, we proceed to refine our CSM to make sure we’re sampling different residential wells that will even be in danger. We are going to proceed this course of till we imagine we have now recognized and sampled the residential wells in danger.”
Fairfield City Supervisor Michelle Flewelling stated she was advised in regards to the farm’s contamination and close by properly testing on Oct. 14 after she spoke with David Burns, the director of the DEP’s Bureau of Remediation and Waste Administration.
“The largest factor is that since we had been notified we have now been actively speaking with of us like DEP and the Division of Agriculture,” Flewelling stated throughout a telephone interview Tuesday. “We on the city workplace have been very dedicated to making sure that each one of our residents have entry to secure and clear consuming water and we’re looking for potential assets for individuals in the event that they’re ready for his or her wells to be examined.”
