Okay, so Camp LeJeune is a really big place where lots of grown-ups who work for the military live and work. It's kind of like a big city, but just for people who work for the military. It's located in North Carolina and has lots of houses, stores, and even a hospital.
Camp LeJeune has been around for a long time, and sometimes grown-ups who used to work there get sick because of something called contamination. That means that there was something in the water or the soil that made them sick.
One of the places on Camp LeJeune that was contaminated was called Camp Leach. It was like a little neighborhood with houses where people used to live, but they don't live there anymore because it wasn't safe for them to be there.
The contamination was really bad and made lots of people sick. Some people had problems with their skin or got really bad headaches, and some people even got really sick. So, the grown-ups who work for the military are making sure that people who used to live at or near Camp Leach get help so they can feel better.
They are also working really hard to make sure that something like this doesn't happen again in the future. They are trying to clean up the contamination so that Camp LeJeune can be a safe and healthy place for people to live and work.
