A groundwater sample was sent to a lab for an analysis of possible uranium contamination coming from a nearby hydraulic fracturing site. The sample gave a signal of 201 μV. To account for matrix effects, 750 μL of the sample was spiked with 50 µL of 500 ppt U. The spiked sample gave a signal of 263 µV. What is the concentration of U in the groundwater sample? 85.0 ppt 0.938 ppt 31.3 ppt 1.79 ppt
