Simple answer -- no. Water requires two things that the present surface of Mars doesn't have -- a higher temperature, and a higher atmospheric pressure.
Water may burst out onto the surface from a subsurface pressurized area and sublimate (become vapor) within seconds, but articles like this create a false impression -- that there could be standing water at the surface of Mars in the present. This is not possible.
Streaks such as are sometimes seen could be a very brief appearance of brackish water in the process of sublimating, essentially boiling away within seconds, but it's not water as we understand that term. I wish people who write articles like this would first learn a little physics.
