A Review of Scientific Literature on the Long-Term Effects of Part II: Water Chlorination - A Synthesis of Toxicology, Epidemiology, and Regulatory Evidence (Health Risks & Benefits of Chlorine)

Jul 4, 2026 · 3 min read

Historical Context: A Public Health Triumph Chlorination of drinking water, pioneered in the early 20th century (e.g., Jersey City, NJ, in 1908), stands as one of the greatest public health achievements of the modern era.

In the US, typhoid fever rates plummeted from ~100 cases per 100,000 people in 1900 to 33.8 by 1920...
