Deltas are typically freshwater environments, formed at the mouth of rivers where they meet larger bodies of water, such as oceans or lakes. The sediment carried by the river deposits as the water slows down, creating landforms. However, the salinity of a delta can vary; in some cases, such as those at coastal regions, brackish water may occur due to the mixing of freshwater from the river and saltwater from the ocean. Overall, deltas are primarily associated with freshwater systems.
It varies, but usually the rivers freshwater mixing into saltwater.

they are both saltwater and freshwater
They contain saltwater and freshwater
The Persian Gulf is saltwater, not freshwater.
Saltwater is heavier because saltwater contains salt which adds to its overall weight. Freshwater does not have any dissolved salt so it is lighter then saltwater

Most lakes contain freshwater. From this fact, I'm assuming it is made out of freshwater, rather than saltwater.
Freshwater and saltwater meet at the mouths of rivers that flow into the sea.
In a freshwater environment it is clean and in a saltwater it has salt.
