Drinking city water is not considered a causal factor in Parkinson's disease. While studies have investigated various environmental and lifestyle factors that may contribute to the development of Parkinson's, the link between city water consumption and the onset of the disease lacks substantial empirical support. Most research highlights other more established risk factors.

For example, drug use may lead to neurotoxicity in some cases, and certain substances have been associated with increased risk for neurodegenerative diseases. Consumption of dairy products has been observed in some studies to correlate with an increased risk of developing Parkinson's, possibly due to their fat content and other components. Additionally, exposure to agricultural chemicals, particularly pesticides, has been strongly linked to higher incidence rates of Parkinson's among agricultural workers and those living in farming communities. This makes these factors more directly associated with the onset of the disease, while drinking city water has not shown a similar consistent link in scientific literature.
