Aggregated National Production Volume: 1 billion pounds and greater., Non-confidential 2012 Chemical Data Reporting (CDR) information on the production and use of chemicals manufactured or imported into the United States. Chemical: Water. National Production Volume: 10, 000 - 50, yr., General Manufacturing Information: Not Known or Reasonably Ascertainable, Other (requires additional information), Water: ACTIVE, Some bottled waters contain fluoride, and some do not. Fluoride can occur naturally in source waters used for bottling or be added. Most bottled waters contain fluoride at levels that are less than optimal for good oral health., People with compromised immune systems may want to take special precautions with the water they drink. In healthy individuals, the parasite Cryptosporidium can cause illness, however, for those with weakened immune systems, it can cause severe illness and possibly death. Look for bottled water treatments that protect against Cryptosporidium, which include: Reverse Osmosis Distillation Filtration with an absolute 1 micron filter., The proper amount of fluoride from infancy through old age helps prevent and control tooth decay. Community water fluoridation is a widely accepted practice for preventing and controlling tooth decay by adjusting the concentration of fluoride in the public water supply, According to the EPA, approximately 286 million Americans receive their tap water from a community water system. These public water systems are monitored and regulated as set by the EPA. An estimated 15% of Americans, or about 45 million people, get their water from private ground water wells that are not subject to EPA regulations. Private ground water wells can provide safe, clean water. However, well water can also become contaminated, leading to illness. It is the responsibility of well owners to maintain and treat their well., For more General Manufacturing Information (Complete) data for Water (10 total), please visit the HSDB record page..
