According to various reports from the Agency for Toxic Substances and Disease Registry (ATSDR), waste disposal practices by an off-base dry cleaner, leaking underground storage tanks, industrial area spills, and waste disposal sites on the base were the main sources of water contamination. However, the water for daily use at the Camp Lejeune base came from three different sources: Hadnot Point, Tarawa Terrace, and Holcomb Boulevard. However, the contaminants were sourced from both on-site and off-site sources.
