Point source discharges are specifically defined as contaminants released from a discrete and identifiable source, such as pipes or ditches. The distinguishing features of point source discharges are that they are typically monitored, controlled, and inspected, which helps in ensuring compliance with environmental regulations. This categorization allows for more effective management and regulation since the sources can be precisely located and measured, facilitating enforcement of pollution control measures.

On the other hand, uncontrolled discharges, intermittent flows, and agricultural runoff do not fit the formal definition of point sources. Uncontrolled discharges may arise from various sources without specific control measures in place, while intermittent flows refer to discharges that do not occur consistently. Agricultural runoff is associated with non-point source pollution, where contaminants originate from broad areas rather than a specific point.
