Cleanup crews worked Monday to contain an oil spill that fouled the white beaches of Niteroi, Rio’s sister city just across Guanabara Bay.
The spill occurred Saturday night, when a Bahamas-flagged ship cracked its hull in a minor accident as it approached a shipyard and leaked 530 gallons of oil into the bay.
Jeferson Martins, the environmental secretary for the city of Niteroi, told reporters he believed the spill was larger than reported and had started leaking earlier.
Rio de Janeiro state environmental officials denied it.
More than 50 truckloads of oil-contaminated sand were removed Sunday from the upscale beaches of Boa Viagem, Flechas and Icarai beaches in Niteroi.
