Drinking newer groundwater linked to up to 62% higher Parkinson's risk

New study suggests the type of water a person drinks may influence the risk of developing Parkinson's disease.
Drinking water from newer groundwater sources, especially carbonate aquifers, is associated with a higher risk of Parkinson's disease compared to older groundwater sources.
Carbonate aquifers, common in the U.S., are more vulnerable to surface contamination, leading to a 24% higher risk of Parkinson's disease compared to other aquifer types.
Glacial aquifers, formed during the ice age, naturally filter contaminants, resulting in a lower risk of Parkinson's disease.
Older groundwater, typically deeper and better shielded from pollution, contains fewer contaminants and is linked to a reduced risk of Parkinson's disease.
The study analyzed data from 12,370 Parkinson's patients and over 1.2 million non-patients, focusing on groundwater age, aquifer type, and drinking water sources.
Findings suggest that groundwater age and location could be environmental risk factors for Parkinson's disease, though further research is needed to confirm causation.
The study highlights the importance of water source quality in long-term neurological health and calls for more research to help communities assess and mitigate environmental risks.
