Water vacuum sampling system (WRASSE)

A method for using a water vacuum sampling system comprising:

• connecting a vacuum port of the water vacuum sampling system to a vacuum;
• turning on the vacuum to draw water, particles, and air from a surface area into an outer housing through a sampling port;
• receiving the water and air that has passed through the sampling port into a velocity dampener cone that is disposed within the outer housing and that flares away from the sampling port so as to reduce the velocity of the water, particles, and air, wherein the velocity dampener cone is perforated to allow the air to escape through the perforations and through a bottom of the velocity dampener cone;
• drawing the air that escapes from the velocity dampener cone into the vacuum through the vacuum port;
• receiving the water and particles that pass through the velocity dampener cone into a catch basin disposed within the outer housing below and mostly surrounding the velocity dampener cone;
• and
• channeling the water and particles received by the catch basin into a sample collection container removably attached to a bottom outlet of the catch basin.
