Can firefighting helicopters use saltwater to fight wildfires or is it just freshwater?

Will the salt have a negative impact on the area after?

They can use saltwater, too. Some things to consider though:

As you mentioned, salt isn't great for re-growth.

Most sources of water nearby forests usually aren't the ocean but instead lakes.

Saltwater can be damaging to water tanks and it causes corrosion more quickly.
