Although mining around the area essentially stopped with the closure of the gypsum mines in 1982, uranium mining has surfaced as a potential problem for the river. The province was the subject of a controversy in 2007 when it gave Vale Limited (formerly known as CVRD Inco) the right to mine for uranium at Turtle Creek, where the Greater Moncton water reservoir is maintained. Environmentalists warned of the dangers related to the move, fearing that contaminants could be pushed into the surrounding water. The Petitcodiac Riverkeeper also noted uranium mining's "irreversible effects to the health of ecosystems, watersheds, wildlife, agriculture, recreation, and public health", and joined 30 other environmental groups in asking the provincial government to establish a ban on the act. The province would later restrict uranium mining to from residential areas and ban it from protected drinking water areas. Another controversy in 2006 involved exploration for oil and gas deposits in the same area, but access was blocked by the municipal government.
