The playing field was closed and surveyed. Investigators found a second line of drums beneath its edge, along with company documents proving the dumping had been planned. Thick clay had prevented the chemicals from reaching the water supply, but tonnes of soil required removal. Calder’s successor company was ordered to fund the cleanup, residents’ temporary housing, and long-term health monitoring.
Pip recovered within days. Mary’s tests showed limited exposure and no sign of lasting harm. Because the fire ants were invasive and contaminated, they could not be relocated. Specialists destroyed the colonies inside sealed treatment zones, then removed their nests with the polluted soil. Native insects would be reintroduced only after tests showed the gardens were safe.
Six months later, Mary returned to the cottage. Clean soil covered the garden, and a young apple tree stood where the mound had been. Daniel visited to remove the final monitoring equipment. “Strange to think ants uncovered all of it,” Mary said. “They were only trying to build a home,” he replied. Mary looked across the grass where Pip was playing. The colony had never belonged in that garden, but it had exposed a secret that was never meant to reach the surface.
