Dynamic environmental water sampling backpack

A field research sampling system, comprising:

• a user worn backpack-mounted sampling system comprising:
• a backpack control module, the control module further comprising:
• a controller casing, a protective lid flexibly connected to the controller casing, a storage compartment proximately disposed within the controller casing;
• said storage compartment capable of receiving:
• preserved filter membranes, storage media for field data collection, pens or pencils for sample labeling and laboratory sample tubes or containers;
• a user interface panel having a display screen;
• the user interface panel further comprising the ability to enter setpoints for system parameters;
• an onboard computer operatively connected to a pump system controller;
• and
• a pump tubing having a first end and a second end;
• the first end of the pump tubing feeding through the controller casing and connected to a variable speed positive displacement water pump, an electric pressure sensor capable of measuring the water pressure in the pump tubing, a pump system controller able to modify the rate of water volume in the pump tubing, a pump driver;
• a power supply module, the power supply module electrically connected to the user interface panel, the onboard computer, the positive displacement pump, the electric pressure sensors, and the pump system controller;
• a water collection and filtration module comprising:
• an induction tube, a filter assembly, a remote flow controller, and a flow rate sensor operably coupled to the second end of the pumping tube, and operatively connected to the onboard computer and configured in a wand-like extension;
• the filter assembly further comprising:
• a funnel shaped upper filter housing, having a tapered-end and an open-end, the open-end of the upper filter housing able to support a filter membrane and a filter screen;
• a funnel shaped lower filter housing, having a tapered-end and an open-end, the open-end of the lower filter housing;
• the open-end of the upper filter housing sealably connected to the open end of the lower filter housing;
• and
• the induction tube operably coupled to the first end of a filter assembly, and the second end of the pump tubing coupled to the second end of the filter assembly
• so that a selectable rate of water is pumped into the sampling system as monitored by the flow rate sensor in operable regulation of water pressure by the pressure sensor yielding a collected sample on the filter membrane of a filter assembly of the filtration module and the flow rate of water is controlled by the onboard computer.
