We are creating a tablet that purifies water and delivers a nutritious "juice". However we are designers, not chemists, and we need some basic guidance.

From "The Call Of The Wild" ..Seven days from the time they pulled into Dawson, they dropped down the steep bank by the Barracks to the Yukon Trail, and pulled for Dyea and Salt Water. I wonder where the Barracks and Salt Water are located. I tried to find them out on a map, but only found the place of Dawson, Dyea, and Yukon Trail. Maybe "Salt Water" means the sea?

I've just moved to the country from New York City, and although many things about living here are easier, the water is really really hard. My skin is fine but my hair looks just awful--where it used to be big and bouncy, it's now flat, dull and frizzy. I tried adding baking soda to my shampoo (per thriftyfun.com) and that helped for about a day but now things are back to terrible. I just came from getting a haircut--which I'd hoped would help--but it's still awful. Help me. Please. Products, techniques, anything?

I just found what looks like mosquito larvae in my cat's water bowl. I use one of those automatic waterers where there is a gallon or so of water in a upside down container, feeding a small bowl of perhaps 2 cup capacity. In the large upside down container, there was actually one live, flying mosquito. In the small bowl that my cat actually drinks from, there were approximately a dozen apparent larvae, about 1/4" to 1/3" in length. Should I be concerned for my pet's health at all? I am not sure how long they were in there, but I changed the water for fresh immediately.
