During a pile-driving operation on the Testimonio site on the eastern border of the Principality last weekend, an unidentified fault in the ground accelerated a flow of sludge that spilled into the valley to the beach.
Although drilling operations were immediately stopped, the muddy waters continued to flow until Monday, at which point clean-up operations were launched.
Those responsible for the response on the Monaco side were in immediate contact with their counterparts in Roquebrune Cap Martin, which borders the area. A surveillance camera will be installed in the valley to monitor this part of the site permanently, to alert the authorities if another similar situation arises.
