A system is provided for ultra-analysis of water for trace impurities. An effective trapping media (4) having internal surfaces which bear active hydroxyl groups thereon functions by binding gels that carry ultratrace analytes and contaminants on their surfaces. An X-ray source (28) may be located adjacent to the trapping medium (4) in situ. The X-rays (29) penetrate the media (4) and are reflected back into a combined emitter/receiver (30) which detects the fluorescence generated in the media (4) by the X-rays (29). The receiver (30) provides an output (31), optionally at a remote location (32) via a communication link (33), which provides data on the identity and quantity of analytes, typically heavy metals, present in the trapping media (4). By including in the transmitted data sent to the receiver (30) the output of the water meter (21, 21A) the display at the output (31) can be formatted in terms of the concentration of the measured analytes within the sampled water stream (1).
