Drinking Water

The right mineral content of calcium and magnesium in bottled water and water filtration system can greatly improve the intake of these minerals and be benifical to a persons health.

In 2004 the W.H.O. presented a document by F.Kozisek of the meeting of experts in Rome in 2003 about nutrients in drinking water. In 2011 they presented a revision. In this latest document they mention the research of Calcium and magnesium in drinking water giving protection against several cancers.

This is the abstract of Dr Kozisek his article:

   Consequences for your body:

  1. Diuretic increase of 20% due to water retention
  2. Water retention
  3. Sodium increase in serum gives hypertension
  4. Loss of Potassium
  5. Excretion from the body of Sodium, Potassium,calcium,Magnesium and iron

Symptoms of these body consequences:
Feel tired, no energy, muscle cramps, heart arythmias, osteoporosis, bloodpressure increase   
and anemia, pre-cancerous colon polyps

Pregnant woman: Oedema, Anemia and preeclampsia

Food preparation: Loss of several minerals, up to 86% while preparing the food.
Risk groups: Expecting woman, baby formula and hypertensive patients

Kidneys:  a) Atrophy of Glomeruli
b) Swelling of endothelium and thus less bloodflow
c) kidney stone formation

Low Magnesium symptoms:
High bloodpressure, Arythmia, Atheriosclerose, Eclampsia, coronary heartdisease, decreased insulin sensitivity and Diabetes 2, Osteoporosis, insomnia, anxiety, constipation, muscle soreness, fatique, headaches, difficulty swallowing and breathing, elevated CRP, endothelium dysfunction, metabolic syndrome

Low calcium symptoms:
High blood pressure, Osteoporosis, hearth problems, Muscle cramps, Blood clothing, more menstrual pains, candida infections, dry skin and brittle nails,nerve transmission problems ,nephrolithiasis(kidneystones), colorectal cancer, insulin resistance,obesity

Calcium Nutrition and Extracellular Calcium Sensing

Relevance for the Pathogenesis of Osteoporosis, Cancer and Cardiovascular Diseases

By Dr. Meinrad Peterlik

Published: 22 January 2013

Abstract: Through a systematic search in Pubmed for literature, on links between calcium malnutrition and risk of chronic diseases, we found the highest degree of evidence for osteoporosis, colorectal and breast cancer, as well as for hypertension, as the only major cardiovascular risk factor. Low calcium intake apparently has some impact also on cardiovascular events and disease outcome. Calcium malnutrition can causally be related to low activity of the extracellular calcium-sensing receptor (CaSR). This member of the family of 7-TM G-protein coupled receptors allows extracellular Ca2+ to function as a "first messenger" for various intracellular signaling cascades. Evidence demonstrates that Ca2+/CaSR signaling in functional linkage with vitamin D receptor (VDR)-activated pathways (i) promotes osteoblast differentiation and formation of mineralized bone; (ii) targets downstream effectors of the canonical and non-canonical Wnt pathway to inhibit proliferation and induce differentiation of colorectal cancer cells; (iii) evokes Ca2+ influx into breast cancer cells, thereby activating pro-apoptotic intracellular signaling. Furthermore, Ca2+/CaSR signaling opens Ca2+-sensitive K+ conductance channels in vascular endothelial cells, and also participates in IP3-dependent regulation of cytoplasmic Ca2+, the key intermediate of cardiomyocyte functions. Consequently, impairment of Ca2+/CaSR signaling may contribute to inadequate bone formation, tumor progression, hypertension, vascular calcification and, probably, cardiovascular disease.

Calcium and Magnesium in Drinking Water and Risk of Death from Kidney Cancer

Published: 29 Nov 2010

The possible association between the risk of kidney cancer development and the levels of calcium and magnesium in drinking water from municipal supplies was investigated in a matched cancer case-control study in Taiwan. All eligible kidney cancer deaths (1778 cases) of Taiwan residents from 1999 through 2008 were compared with deaths from other causes (1778 controls), and the levels of calcium and magnesium in drinking water of these residents were determined. Data on calcium and magnesium levels in drinking water throughout Taiwan were obtained from the Taiwan Water Supply Corporation (TWSC). The control group consisted of individuals who died from other causes, and the controls were pair-matched to the cancer cases by gender, year of birth, and year of death. The adjusted odd ratios for death attributed to kidney cancer for individuals with higher calcium levels in their drinking water, as compared to the lowest tertile, were 0.89 (95% CI = 0.72–1.11) and 0.78 (95% CI = 0.62–0.98), respectively. The adjusted odd ratios were not statistically significant for the relationship between magnesium levels in drinking water and kidney cancer development. The results of the present study demonstrate that there may be a significant protective effect of calcium intake from drinking water against the risk of death due to kidney cancer.

The municipal water is produced via a combination of desalination process and recently also via reverse osmosis. After obtaining this distilled water, the water is treated to obtain a pH level of around 9.3 The reason for this may be prevention of corrosion of the piping network. For more information on this topic contact the company. The water company and its laboratory analysts do a very good job delivering water year after year. How they accomplish this you can find on their website.

Their calcium and magnesium content is accordingly to the WHO guidelines. There are no guidelines for minimum and maximum for calcium and magnesium established by the WHO.

One analysis we did in 2012 showed a calcium ppm of 4.7 ppm and magnesium less than 0.03 ppm.

City Water Certified Laboratory test - October 2012

For more information on this topic contact the company.

The water content information on the WEB internet page is from 2004. We are now in 2014.


The ppm of the water is around 15-19, which is almost pure. We can conclude that this is very low mineral water.


We couldn't find any policy on home and office plumbing systems. Hardware stores still sell solder with lead
which is a health risk.
