Biological synthesis in a few words: this water comes close to a mineral water because of its calcium and magnesium intake while containing little sodium and potassium (the latter are less desirable because we already find enough in our food).
Regarding micronutrients and micropollutants, there are not really any good points.
The biggest advantage is the total absence of pesticides.

Quality control of the water of Lourdes in June 2016



The results of the field measurements are:

  • the temperature of the water in the cave is 19,90 ° C (limit maximum 25 ° C)
  • calco-carbonic equilibrium is stable with a PH of 8.50 Uniteph (the limited maximum is 9,00)
  • the residual disinfection treatment reveals a 0.08 mg/L chlorine dioxide
The organoleptic characteristics of the laboratory analysis are exceptional with an aspect qualititif of 0, a qualitative color of 0, a qualitative smell of 0, a qualitative flavour of 0 and a turbidity 0.15 NFU (max 2.00 constraint) nephelometrique

The Massabielle spring water mineralization displays a conductivity at 25 ° C of 319 uS/cm (mini quality 200 and maxi 1100 references)

Settings azotes and phosphors of the water show an ammonuim less than 0.05 mg/L (maximum limit of 0.10)

The microbiological parameters also the following data:

  • the search for the so-called no pathogenic aerobic microorganisms "revivable" allowing to count bacteria reveals 208 n/ml at 22 ° - 68 h and 9 n/ml to 36 ° - 44 h
  • the enumeration of coliforms (Enterobacteriaceae family) reveals a result of 0 n / 100mL
  • 0 n / 100mL sulfito-reducing anaerobic bacteria shows a very good quality of natural filtration of groundwater in the water of Lourdes
  • Enterococcus bacteria of oval shape, belonging to the family of Group D streptococci, is also 0 n / 100mL
  • the e. coli (Escherichia coli), naturally occurring bacteria in the intestinal flora, is also absent from this water: 0 n / 100mL
  • Research of the by-products of disinfection (chemical, organic and inorganic substances that can be formed during the reaction of a disinfectant with of the organic matter present in water) reveals 0,197 mg/L for chlorite (maximum of 0.20)
From a health point of view, this control of the water intended for human consumption meets the requirements of quality remaining It meets the criteria of potability

The absence of microorganisms (bacteria, viruses and parasites) in water of lourdes demonstrates a very good quality of this water particularly in natural maintenance of the filtration and catchments of the cave structures.

From a scientific or spiritual point of view, the studies on the water of Lourdes still to reveal all their secrets. The old scientific proverb "Are proving by reason and a reason beyond" will continue to reason in the head of researchers as long as the spirit of the elites will open no consensual guidance.

Comments on the water of Lourdes:

In addition to the already recognized qualities, adds:
  • This water is buffered to absorb variations in pH,
  • It presents exceptional organoleptic qualities: its color, its transparency,
  • Its flavour and odour are unique, the water is a great natural purity,
  • It is free of any pesticide.

In a few words : an extremely beneficial water!

Result of the analysis:

  • Turbidité (NF EN ISO 7027) : 0.23 NFU
  • pH (mesure en laboratoire) - Température de mesure : 20.5°C (NF EN ISO 10523) : 8.1
  • Conductivité à 25°C - Température de mesure : 20.5°C (NF EN 27888) : 321 uS/CM

  • Alcalinité totale (TAC) (NF EN ISO 9963-1) : 15.1 °f
  • Nitrites (NF EN 26777) : < 0.05 mg/l NO2-
  • Ammonium en NH4 (NF T 90-015-2) : < 0.05 mg/l NH4+

Comments:

  • It is a very little water in organic content. It is a great organic purity.
  • The water of the cave is very clear because of its typical low turbidity of source water. To present such a turbidity or clarity, the waters of town in advance are extremely filtered.
  • It is a buffered water to very slightly lasts (above 15 french degrees of hardness and alkalinity).
  • All this shows that this water is slowly filtered by the rocks which have retained any organic contamination but have in Exchange conferred a high mineral content.
  • Throughout his long journey in the different strata (or layers) geology of the Pyrenees, Lourdes water was finely filtered over time and was against part responsible for minerals that could subtract (or dissolve) volcanic rocks.
  • This has given him great organic purity and a wonderful clearness containing essential minerals for rehydration of the body.
