The number of total coliform (TC) samples required to be collected in a water system is determined primarily by the population size served by that system. The rationale behind this is to ensure that water quality monitoring is proportionate to the number of people who rely on that water supply. Greater populations may be at higher risk if contamination occurs, necessitating more frequent and comprehensive testing to ensure safety.

While factors such as water source quality, infrastructure length, and water usage patterns can influence overall water management and safety procedures, they do not directly dictate the number of TC samples that must be taken. For instance, a high-quality water source might reduce the likelihood of contamination but does not change the regulatory sampling requirements based on population size. Therefore, population size serves as a critical benchmark in public health standards for water testing, ensuring adequacy in monitoring and protection for the community relying on that water system.
