Abstract: A system for assessing the quality of air and/or drinking water, the system comprising a plurality of sample traps, wherein each of the sample traps is configured to test for a different environmental contaminant; a base unit having a pump for drawing air, a mount for connecting a sample trap to the pump so as to draw air through that sample trap when the pump is operated, a central processing unit (CPU) pre-programmed to operate the pump in a plurality of modes of operation, and a plurality of buttons communicating with the CPU; and a marking scheme comprising a plurality of unique markings, wherein each of the buttons is marked with a different unique marking, and further wherein each of the sample traps is marked with the same unique marking as the button which causes the pump to operate in a particular mode of operation.

Abstract: A system for assessing the quality of air and/or drinking water, the system comprising: a plurality of sample traps, wherein each of the sample traps is configured to test for a different environmental contaminant, and further wherein at least some of the sample traps require air to be drawn through that sample trap at a particular rate, and for a particular time duration, in order to properly test for a particular environmental contaminant; a base unit, the base unit comprising: a pump for drawing air; a mount for connecting a sample trap to the pump so as to draw air through that sample trap when the pump is operated; a central processing unit (CPU) pre-programmed to operate the pump in a plurality of modes of operation, wherein each mode of operation causes the pump to draw air at a particular pump rate, and for a particular pump time duration; and a plurality of buttons communicating with the CPU, wherein activating a particular button causes the CPU to operate the pump in a particular mode of operation;
