More than 1.3 MILLION Californians may be drinking water with chemicals linked to Parkinson’s
More than 1.3 MILLION Californians may be drinking tap water high in chemicals linked to cognitive problems and Parkinson’s disease
More than 1.3 million Californians may be drinking high levels of manganese, enough to cause cognitive disability in children and Parkinson’s-like symptoms in adults.
The discovery was made by researchers at the University of California – Riverside (UCR), who discovered that the mineral thrives in untreated wells throughout the Central Valley.
The study found private wells and public water systems, with nearly half of affected residents living in disadvantaged communities — nearly 89 percent likely have access to water heavily contaminated with manganese.
While manganese is found in water supplies around the world, the US is one of the few nations that does not enforce a maximum level.
The research comes as the University of Los Angeles may have uncovered a link between lithium in drinking water and autism.
The study found that more than 1.3 million people living in the Central Valley region may be exposed to high levels of manganese in their drinking water
Samantha Ying, UCR soil scientist and principal investigator on the study, said in a statement: “Compared to the state’s total population, it is a relatively small number of people who receive the polluted water.
“But for them, the health risks are high.”
Recent studies have found that exposure to excessive levels of manganese can trigger Parkinson’s-like neurological symptoms due to the mineral building up in the basal ganglia area of the brain.
The team notes that residents could take matters into their own hands by purchasing treatment options ranging from oxidation and precipitation filters to water softeners, chlorination and reverse osmosis systems.
However, such water quality monitoring devices can cost as much as $400 per year.
“It is possible to buy manganese filters, but many people cannot afford them. Our hope is that people in these communities can be subsidized to buy treatment options,” Ying said.
The team chose to study the Central Valley because it is considered one of the most productive and economically important agricultural regions in the United States and is home to one-third of the state’s domestic well users.
“These analyzes demonstrate the need for additional well monitoring programs that assess Mn and improved access to point-of-use treatment for domestic well users who are disproportionately burdened by the associated water treatment costs,” states the study, published in Environmental Science & Technology .
Experts found levels high enough to cause cognitive disability in children and Parkinson’s-like symptoms in adults
The study on lithium in drinking water found that pregnant women who drank water contaminated with the mineral had a moderately higher risk of their offspring being diagnosed with autism spectrum disorder.
The study’s lead author, Beate Ritz, said in a statement: “Any drinking water contamination that can affect the developing human brain deserves intensive scrutiny.
“In the future, anthropogenic aquatic lithium sources could become more widespread due to lithium battery use and landfill disposal with the potential for groundwater pollution. The results of our study are based on high-quality Danish data, but need to be replicated in other populations and regions of the world.’
Ritz worked with Danish researchers who analyzed lithium levels in 151 public waterworks in Denmark, about half of the country’s water supply.
The team pulled from a nationwide database to find out which systems served households with pregnant mothers from 1997 to 2013, and then compared 12,799 children diagnosed with autism to 63,681 children without an autism diagnosis.
The results showed that the autism diagnosis increased with higher lithium levels.
“Compared to the lowest quartile of recorded lithium levels — in other words, those in the 25th percentile — lithium levels in the second and third quartiles were associated with a 24 to 26 percent greater risk of autism, the team said in a press release.
“The risk in the top quartile was 46 percent higher than in the bottom quartile.”
