Hanover's The Evening Sun newspaper reports crews sprinkled lime to prevent the milk from curdling, which could cause a horrendous smell and attract flies.
A truck that overturned Thursday near York Springs spilled about 3,000 gallons of milk into a creek. State environmental officials cleaned up about 90 percent of it with vacuum trucks.
Concerns then turned to milk that had seeped into the soil.
A spokeswoman for the Pennsylvania Department of Environmental Protection says putting lime in the soil chews up the milk's fat, neutralizing the odor.
