tap water is safer than bottled water because tap water is regulated by the EPA which requires municipalities to test their water hundreds of times a month. they require water to have a maximum concentration of various chemicals including nitrates.
http://www.epa.gov/OGWDW/contaminants/dw...
the maximum contaminant level goals (mclg) for nitrate is 10 parts per million (ppm). for nitrite, the mclg is 1 ppm.
however, these maximum numbers are merely goals, and there is no federal law to enforce them. however the EPA does require municipalities to tell the people living in their service area about their water quality.
new york city for instance tests their water dozens of times daily, and publishes an annual report on their website telling poeple about the state of their water supply and what average levels were found as well as any violations that happened.

bottled water on the other hand is less regulated than tap water. bottled water and soda is regulated by the FDA and they don't set any maximum nitrate/nitrite levels, nor require bottlers to test their water as frequently as the EPA requires for tap water suppliers. however, the FDA in recent years have been trying to emulate the EPA in setting maximum goals. in any case, the FDA only cares about is if the bottler bottles the water in a clean and sanitary manner, and that the label reflects what's in the bottle.
as for sources of nitrates and nitrites
fertilizers remain the #1 source for nitrates in the environment due to soil runoff into ground water etc.
http://www.epa.gov/OGWDW/contaminants/dw...
air pollution can also contribute somewhat to nitrates in the environment where rain will wash the nitrates out of the atmosphere (from polluting industries) in the form of acid rain. lightning is also a big source of nitrates when lightning converts nitrogen in the air into nitrates. concentrations in rain water vary from place to place.
toilet water and sewage. there are a lot of nitrates found in soil run off from farms, and from cow and animal wastes. concentrations vary from place to place.
Rain water is accumulated from only the clouds of the sky above us. Toilet water is basicaly reusable water from the waterworks or possibly the filter in your toilet system. Spring Bttled Water comes only from the finest mountain springs known to man, and is not filtered with any extra supplements or artificial ingredients. Tap water could possibly be filtered water from water factories, although, Tap water is no difference from Spring Bottled water, but, Tap water may contain artificial ingredients and or supplements that make the water taste very bland or oldish like. and School drinking water is recycled Toilet and Sewer water,(This may sound repulsive but is very true) I have also researched many different articles considering School drinking water.
