Home tap water is safe
When the surrounding pollution grows, of the earth, industrial, of the air that is, consequently also the contaminants and polluted substances of the tap water increase. Fortunately, the European regulation comes to the aid, with the application of a constant control thanks to millions of analyzes per year, of 50 chemical and microbiological parameters.
Between livelil and parameters that change over time, we can say that tap water in Italy is generally safe (Repubblica.it), special cases apart, but Italians prefer to drink bottled water, so they find themselves in third place for consumers after Mexico and Thailand.
Parameters of water quality
According to the Ministry of Health, there are certain parameters regarding the quality of the water to be considered. In particular, we read that "water must comply with a series of microbiological parameters (Legislative Decree 31/2001, part A) and chemicals (part B), as well as indicator parameters (part C) that cannot be directly correlated to risks for the health, but indicators of changes in water quality " . The decree establishes in fact that the local health unit ensures an additional research, on a case-by-case basis, of the substances and microorganisms for which no parameter values have been set, if there is reason to suspect the presence in quantities or concentrations such as represent a potential danger to human health.
On the indicated site it is therefore possible to read all the parameters: microbiological, chemical, indicators and emerging that it is essential to consider, let's see a summary.
Faucet water contaminants
Among the possible water contaminants, here are some whose value is to be monitored and controlled in the first place:
> Bacteria, such as enterococci and escherichia coli.
> Chemicals, including acrylamide, antimony, arsenic, boron, cadmium, cyanute, chlorite, chromium, fluoride, polycyclic aromatic hydrocarbons, mercury, nickel, lead, copper, selenium, vanadium and others.
> Indicator parameters that can not be directly correlated to health risks, but nevertheless indexes to changes in water quality, such as aluminum, chloride, ammonium, color and taste, colony count, conductivity, concentration of hydrogen ph ions, residual disinfectant, iron, hardness, odor, dry residue, sulfate and turbidity, among others.
> Lastly, we must consider the so-called "emerging parameters", concerning those that are considered significant in recent years, and they are asbestos, PFOS and PFOA (respectively (perfluorooctane sulfonic acid and perfluorooctanoic acid, often used at industrial level), thallium .
