It's not good, desalination plants have to mitigate this with long diffusers that regulate the rate and concentration of the brine that is being put back into the ocean.

Sounds like it’s easily solved with a diffuser.

  It's a very difficult problem to solve at human scale. And getting it wrong can have catastrophic impacts. Even if 100% of grey water runoff is mixed with the brine, the resulting concentration is still high enough to cause a localized collapse in the ocean if it isn't properly regulated.

    So, again, sounds like diffusing it to appropriate levels within the natural salinity variance solves the problem just fine.
