Harmful to your health. Very few, if any, benefits are present. Things in this category should be avoided as much as possible.
Category 'D' is typically for things that are more harmful than beneficial. While consuming/doing something unhealthy once in a blue moon shouldn't hurt, we definitely recommend eliminating 'D' items as a regular part of your routine/diet.
Category 'F'
Category 'F' is for things that fail to bring anything beneficial to the table, and are very harmful to your health. We recommend completely avoiding anything in this category. Long-term side effects of 'F' items are usually very serious.
Category 'N'
'N' stands for neutral. Things placed into this category are generally (a) neither good nor bad for you, or (b) lack the necessary evidence to reach any conclusions.
Long answer
Kirkland Signature Water is distilled water from the Rocky Mountains near Kirkland, Colorado. They source their water from the city of Kirkland, which gets it from the Cedar River Watershed and the South Fork Tolt River Watershed. They consistently use clearly identifiable sources. These sources are not significantly polluted because they are in a remote location.
The reviews of Kirkland Signature Water are overwhelmingly positive. Customers claim that it tastes good; that "it tastes clean" and it's "crisp" and "smooth". Kirkland water is sold at Costco and it's very affordable.
The plastic is very thin, meaning it is less wasteful and less harmful to the environment. However, they should be gripped lightly after opening so the water doesn't spill all over the place! The bottles are 100% recyclable. Kirkland Signature Water bottles do not contain BPA, a chemical found on many plastics that is harmful to your health if ingested.
Kirkland Signature Water does not contain fluoride, which many other bottled waters do. Those who are especially concerned with fluoride in tap water and bottled waters have the option of using this very cheap brand of bottled water.
The manufacturer for Kirkland Signature Water is a company called DS Services, which is a member of the International Bottled Water Association. There are strict regulations in place for all members of the association. DS Services uses extensive filtration and reverse osmosis to purify their water and uses ozone and ultraviolet radiation to disinfect it. Distilled water also goes through a water softening process to remove minerals, before they add their light blend of minerals that are often found in food in order to enhance the taste.
Certified labs have tested Kirkland Signature Water and found it to be contaminant free. Their water quality analysis tested for inorganic chemicals, metals, dozens of kinds of harmful organic chemicals, and radiological and other contaminants. The results indicated very safe levels for all contaminants tested for. There were measurable levels of many of these before purification, yet very few of them were detectable and none of them at dangerous levels after the purification process, which clearly demonstrates its effectiveness. The pH of Kirkland Signature water is 6.0, slightly acidic.
