Quick Answer
Drinking distilled water from plastic containers is generally safe, but potential contaminants can leach into the water, especially if the plastic is damaged, scratched, or exposed to high temperatures.
Chemical Contaminants from Plastic
Plastic containers can leach chemicals such as Bisphenol A (BPA), polycyclic aromatic hydrocarbons (PAHs), and volatile organic compounds (VOCs) into the distilled water. These chemicals are often used in the production of plastics and can be toxic to humans in high concentrations. When handling plastic containers, ensure they are BPA-free and in good condition to minimize the risk of leaching.
Risk Factors and Precautions
The risk of chemical contamination from plastic containers is higher when the plastic is scratched, damaged, or exposed to high temperatures. For example, water stored in plastic containers at temperatures above 60°C (140°F) can increase the leaching rate of chemicals into the water. To minimize this risk, store distilled water in plastic containers at room temperature, and replace containers every 6-12 months.
DIY Water Distillation Systems
When building a DIY water distillation system, choose food-grade materials, such as glass or stainless steel, to minimize the risk of chemical contamination. Avoid using plastic containers or parts that can leach chemicals into the distilled water. Consider using a distillation system with a condenser coil made from copper or stainless steel to further reduce the risk of contamination. Always follow proper cleaning and maintenance procedures to ensure the distillation system remains safe and effective.
