What term describes the process by which organic compounds pass through plastic pipe?

The term that describes the process by which organic compounds pass through plastic pipe is permeation. This process involves the movement of molecules from an area of high concentration to an area of lower concentration, allowing certain substances to pass through the material of the pipe itself. In the context of plastic piping systems, this is particularly significant because certain organic compounds can migrate through the wall of the pipe due to their chemical properties and interactions with the plastic material.

Permeation is essential to understand as it can impact water quality by introducing contaminants from the pipe into the water it carries. This is especially relevant for water operators who must ensure that materials used in plumbing systems are compatible with the types of fluids they will carry and are not prone to leaching harmful substances.

Understanding permeation helps operators make informed decisions about the materials they use for water distribution systems, contributing to the overall safety and quality of drinking water.
