Clean Water Act 33 U.S.C. § 1362(14) & 40 CFR § 171

Point-source pollution originates from a specific, identifiable, and confined discharge point, such as a spill at a mixing/loading pad, an equipment wash site, an accidental storage leak, or back-siphoning into a wellhead. Non-point source pollution comes from diffuse, broad areas (e.g., field runoff).
