Sixteen of the crew members were rescued by the Philippine Coast Guard (PCG).

The oil spill had a significant risk of impacting the livelihoods of local fishermen by damaging the marine environment of Manila Bay (according to a PCG spokesperson).
Fish samples taken from parts of the province before the appearance of oil slicks had already tested positive for petrochemicals.

Apart from air and water contamination, damage was also caused to coral reefs and mangrove areas. The Department of Environment and Natural Resources (DENR) estimated that around 4,700 hectares of critical ecosystems and 44 sites linked to the Asian Waterbird Census could be affected within a 30-kilometer radius of where the Terranova sank

On July 30, a no-fishing zone was imposed on Limay.
Daily economic losses in the province was estimated at nearly P18 million (roughly 0.31 million USD). The Department of Agriculture estimated that total damages to fishing had reached P78.69 million (roughly 1.35 million USD), directly affecting 28,373 people.

Authorities estimated that around 350,000 people, including around 25,000 working in the fishing industry, were affected by the oil spill in Cavite.

The PCG started using floating barriers and siphoning using water buckets to clean up the oil slick.
Booms, including those made from coconut husks, and dispersants were also used after divers found the cargo was leaking from the valves.

The PCG estimated that siphoning of the cargo would take a week. The siphoned IFOs would be transferred to another ship (the MT Helena Marie).

The PCG ordered the sealing of nine leaking valves before the start of the siphoning on July 30. There was a need to replace the initial capping bags on the valves of the vessel with metal ones to prevent more discharges during the actual removal and transfer of fuel oil.

On August 5, the PCG said that the oil sheen from the Terranova had been contained. .

On September 12, a contracted salvor reported that they recovered 1,415,954 liters of oil and an additional 17,725 kilograms of solid oily waste as part of the variance volume representing a recovery rate of 97.43%. The remaining 37,867 liters, accounting for 2.57% of the total oil cargo, were lost due to various factors such as biodegradation, dissipation, absorption by sorbent booms, and unpumpable sludge left in the tanks.
