Certain components of drinking water can have adverse health effects. Epidemiological studies have examined the relationship between exposure to trace elements, such as Ca2+, Mg2+ and Na+, which have important physiological functions and inadequate intake of these minerals may increase the likelihood of disease. Bottled water comes from a variety of sources, including many of the same sources as tap water. Sometimes it is simply public tap water that has been improved in some way, for example by changing the mineral content.
Other sources of bottled water include springs, wells, and surface water. Backflow occurs at the connection points between drinking and non-potable water supplies (cross connections) due to differences in water pressure. Adult men can achieve between 6 and 23% of their Mg2+ DRI, and adult women can achieve between 8 and 31% of their Mg2+ DRI by drinking 2 liters a day. We obtained the levels of Ca2+, Mg2+ and Na+ for 37 commercially available bottled waters from North America based on a previous study and published data on bottled water. We request information on the levels of Ca2+, Mg2+ and Na+ for all water sources in each of these municipalities. In addition to maximum contaminant levels, EPA regulations include standard methods for testing water, as well as analytical methods for determining compliance with chemical and microbiological contaminants in drinking water.
Northfield works hard to provide you with safe and reliable drinking water that meets federal and state water quality requirements. The levels of Ca2+, Mg2+ and Na+ in tap water were obtained from municipal analysis reports, and the levels of Ca2+, Mg2+ and Na+ in bottled water were obtained from published data. Variations in the mineral content of different water sources were also found within the same North American city. Risk coefficients for the types of myocardial infarction, ischemic stroke and hemorrhagic stroke according to tertiles of exposure to magnesium in drinking water in 26,733 women from the Swedish mammography cohort were also studied. You can also request information on how you can participate in decisions that may affect water quality. Over the past decade, tap water consumption in North America has declined as sales of commercially available bottled water have increased. Sodium levels in tap water are generally low, but dietary intake of Ca2+ and Mg2+ can be supplemented by drinking at least 2 liters a day from mineral-rich tap water sources.
Although there are numerous studies on minerals and drinking water in relation to cardiovascular mortality, mainly death from myocardial infarction, epidemiological evidence on the association with stroke is very limited. Drinking water can be an important source of Ca2+, and mineral water rich in Ca2+ can provide more than one-third of the recommended dietary intake of this mineral in adults. So what is the average magnesium content of bottled water in central Minnesota? The answer depends on where it comes from. Generally speaking, bottled waters sourced from springs or wells tend to have higher levels of magnesium than those sourced from public tap water.
However, variations in mineral content can occur even within the same city or region. It is important to check with your local municipality or bottled water company to find out more about the specific magnesium content of their products. When it comes to understanding what is contained within your bottled drinking water, it is important to be aware that different sources may contain different levels of minerals such as calcium, magnesium, sodium, etc. In order to determine what is contained within your particular bottle of drinking water, it is best to contact your local municipality or bottled water company for more information about their specific product.
By doing so, you will be able to make an informed decision about which type of bottled drinking water is best for you based on its mineral content. Additionally, you will be able to ensure that you are getting enough magnesium through your daily intake by selecting a bottle that contains higher levels of this essential mineral.
