The rare earth element gadolinium is often used as a contrasting
agent for MRIs. The concentration of gadolinium was measured in the
discharge from a wastewater treatment plant near a large medical
facility. Eight measurements were obtained: 1.212001.21200 ppm,
1.212001.21200 ppm, 1.209001.20900 ppm, 1.203001.20300 ppm,
1.777001.77700 ppm, 1.201001.20100 ppm, 1.218001.21800 ppm,
1.201001.20100 ppm.
