Walmart doesn’t just scrimp on employee wages. It also scrimps on employee training, and that led to its workers dumping returned pesticides, bleach, and other hazardous products into the trash or sewer systems.

On Tuesday, Walmart pled guilty to violations of federal environmental laws and agreed to pay $81.6 million in fines and penalties for improper hazardous waste disposal.

From an EPA press release:

[U]ntil January 2006, Wal-Mart did not have a program in place and failed to train its employees on proper hazardous waste management and disposal practices at the store level. As a result, hazardous wastes were either discarded improperly at the store level — including being put into municipal trash bins or, if a liquid, poured into the local sewer system — or they were improperly transported without proper safety documentation to one of six product return centers located throughout the United States.
