My first suggestion: My wife, Sharon, and I have traveled in many third-world countries. Had we bought or used bottled water (that was often included in a tour) the bottles would have ended up in a landfill or as litter (as do 80% of the single-use water bottles in this country). Instead we always travel with reusable water bottles and fill them from any tap. Then we add 2 drops of liquid 2% Tincture of Iodine (not betadine) to each quart of clear water (10 drops to 1 quart of cloudy water). Shake well and allow to stand for 30 minutes before drinking. To neutralize the iodine taste you can add ¼ tsp of crushed vitamin C tablets. The Tincture of Iodine and Vitamin C are readily available at any drugstore.
