The Great MSSC Water Taste Test

How good is your palate?
Different Salinity Levels in Your Water, Can You Really Tell?

During the MSSC 2020 Annual Summit, a taste test of four water samples ranging from 100 ppm to 1500 ppm total dissolved solids (TDS). These samples were prepared from ultrafiltered brackish water from El Paso and blended with distilled water. The goal was to see whether MSSC Summit attendees could detect the difference based on taste. During the Summit, 77 participants tasted four different water samples and 37 of these folks (48%) got all four correct! A total of 36 people chose Sample B (500 ppm) as the best tasting, 25 chose Sample D (100 mg/L), and two said B & D. Interestingly two people chose the most brackish water, Sample C (1500 mg/L) as their favorite (maybe they are used to West Texas water!). Five attendees got all four samples wrong – which might have been because the prize was so attractive. A drawing was held to award a prize to the best and worst tasters. Do you think you can do better?

Before coming to Las Vegas, test runs were performed at El Paso Water’s headquarters (thanks to the employees for the feedback!). Similar to the tests done at El Paso Water, most people could correctly identify the brackish water (especially Sample C). The correct answers were: Sample A (red)=1000 mg/L TDS, B (green)=500 mg/L, C (yellow)=1500 mg/L TDS, and D (blue)=100 mg/L TDS. It did appear that B & D were more challenging to separate, but a larger sample size and/or repetition is probably necessary to verify the significance of the difference of results.
