Canada's Nova Scotia province has given the go-ahead for 5Ml of hydraulic fracturing wastewater to be disposed at the Lafarge Brookfield plant following a successful pilot project earlier this spring.

The province’s Environment Minister, Randy Delorey, said in a statement he's approved a request from Atlantic Industrial Services to use the waste water at the Brookfield plant.

The leftover waste water from drilling that took place seven years ago, estimated in 10 million litres, are currently in two ponds at the Atlantic Industrial Services site. Half of it will be moved in the coming weeks and it is estimated that about 167 truckloads of water will be needed to complete the transfer. The water will be used as a coolant in the Lafarge kiln and evaporated at 700°C
