Chris - as you say, rainwater is very low in electrolytes - it gets very little opportunity to dissolve electrolytes from dirt particles and other sources in the atmosphere or from the substrate it is collected from. The electrical conductivity (Ec) of the water is a measure of the dissolved salts or electrolytes. Rainwater would typically show an Ec below 30uS/cm which equates approximately with 15 parts per million (ppm) total dissolved salts (TDS). Townwater supplies are typically 100-300 uS/cm equating to 50-150 ppm TDS.

Forgot to ask whether any of our gliding scientists would have any information on tankwater electrolytes. My gut feeling is there would be little present.

I only have rainwater which is roof captured away from urban pollution. Previous postings on this list raised my curiosity along with the remarkable improvement in my family's dental health after we added a fluoride mouthwash to the shopping list. Many country people on the list would probably be interested too and especially me as I am not a great eater of the type of foods that contain electrolytes (Gliding Doctors flamesuit on). BTW the person who suggested the electrolyte drink a while before flight on top of hydration is thanked by my brother in law who plays veteran tennis and recently beat everybody (some a lot younger) on a 40c day on that advice passed on. He said he felt the best ever, even at the end of the day.
