Very healthy and numerous health benefits. A few harmful qualities may be associated, but only under certain circumstances such as an allergic reaction.

A-

Very healthy and numerous health benefits. Harmful qualities may be associated, but aren't usually serious.

It is important to note that even the best things in life can become bad in immoderate amounts. So, although something may be rated an 'A+', overconsumption/overdoing can bring unwanted effects.

Category 'B'

B+

Very beneficial to your health. Things rated a 'B+' may have a few harmful qualities to pay attention to.

B

Overall beneficial to your health. Things rated a 'B' may have some harmful qualities to pay attention to.

B-

More beneficial to your health than not. However, harmful qualities are most likely associated and shouldn't be overlooked.

The main difference between category 'A' and category 'B' is the harmful qualities typically present in 'B' items. Serious side effects are usually uncommon, but are still possible and should be taken note of.

Category 'C'

C+

Both beneficial and harmful qualities associated. Things rated a 'C+' are typically a bit more on the beneficial side. Still, moderation is important.

C

A fairly even ratio of beneficial and harmful qualities. Moderation is important. Very general topics that can lean towards both sides of the spectrum will be placed here as well. Rice, for example, can be good or bad depending on the type.

C-

More harmful than beneficial. Side effects are common, especially when consumed/done excessively. Moderation is very important.

Category 'C' usually denotes to both good and bad qualities. When it comes to this category, it is important to keep this word in mind: moderation.

Category 'D'

D+

Harmful to your health. Although benefits may be associated, the bad most likely outweighs the good. Moderation is very important.

D

Harmful to your health. A few benefits may be associated, but the bad outweighs the good. Moderation is extremely important.

D-

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'

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

'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.

You can feel safe drinking Kirkland Signature Water.
