Drinking Zamzam Water and its Health Risks
The Well of Zamzam is a well located within the Masjid al-Haram in Mecca, Saudi Arabia, 20 meters (66 feet) east of the Ka'aba, the holiest place in Islam. The well is 35 meters deep and topped by an elegant dome.
Millions of Muslims visit the well each year while performing the Hajj or Umrah pilgrimages, in order to drink its water and, in many cases, to take home some of its water for distribution among friends and relations.
The Islamic beliefs in regards to its history is expounded upon by the Saudi Geological Survey website:
Miraculous Status Within Islam
Not only do Muslims consider the well to be miraculous, but also the water which it pumps. Several hadith narrations have been recorded concerning this.
Prophet Mohammed (pbuh) said it has healing effects. This is why pilgrims to Makkah to this day collect it in bottles, to bring back for relatives and friends back home who are ill.
It is also reported also that the Prophet rubbed the gums of his two grandchildren - Hassan and Hussain - with dates and ZamZam. It was also reported that the Prophet used to carry the water of ZamZam in pitchers and water skins back to Madinnah.
He used to sprinkle it over the sick and make them drink it.In some Hadith, it has been reported that the water of ZamZam has healing effects. In one Hadith it is said: Narrated by Jabir that the Prophet Mohammed (pbuh) said: "Water of ZamZam is good for whatever purpose it has been drunk. In another Hadith the Prophet said "Water of ZamZam is a healer of every disease. Muslims throughout the world do believe that the water is blessed and accordingly it is considered as one of the best gift to be offered.
Muslim Claims Regarding the Science
It was found that the ZamZam water has a curative effect.
Alkaline in nature, the ZamZam water can neutralise excess hydrochloric acid formed in the stomach and reduces heartburn.
Iodide, sulphate and nitrate contents are also much higher in the ZamZam water. Supply of iodide through ZamZam may sufficiently fulfil the requirement of iodide for the thyroid organ of a body. The research was carried out jointly by M. A. Khan, A. K. M. Sheriff, K. M. Idris and M. Alamgir.
It was revealed that contents of macro-nutrients like magnesium, sodium and potassium were manifold higher in ZamZam water than in tap and solar pump water.
The scientists said all the data indicated that ZamZam water had much more nutritive values than ordinary underground water.The hardness of ZamZam water is four times that of tap and solar pump water but it is within the acceptable limit set by the WHO, the researchers found.
Arsenic poisoning is caused by increased levels of the element arsenic in the body. Symptoms of arsenic poisoning include headaches, confusion, sleepiness, convulsions, vomiting, diarrhea, kidney, liver and lung problems, and can even result in coma or death.
The World Health Organization state that a level of 0.01 mg/L poses a risk of 6 in 10000 chance of lifetime skin cancer risk and contends that this level of risk is acceptable.
Fluoride and Other Naturally Occuring Elements
Fluoride is found naturally in low concentration in drinking water and foods. In these small naturally occuring amounts fluoride is beneficial, and the fluoridation of water is known to prevent tooth decay.
On the other hand, arsenic is a toxic element that has no apparent beneficial health effects for humans regardless of the quantity consumed.
Arsenic and Zamzam
In October 2005, the British Food Standards Agency issued warnings against "fraudulent" Zamzam water being commercially sold which contained dangerous levels of arsenic (over three times the legal limit recommended by the World Health Organization).
Zam Zam water, which is sacred to Muslims, comes from a specific source in Saudi Arabia and cannot legally be exported from the country for commercial sale.
A brand of Zam Zam formally sampled by the London Borough of Westminster has been found to contain almost three times the permitted level of arsenic, which could contribute to increasing people's risk of cancer.
The local authority has taken action to prevent further sale of the product from the outlet.
In addition they have contacted the importer of the water to ensure that they stop importing the product. No other outlets are known to have stocked this product.
Other brands of Zam Zam water are thought to be on sale in the UK and could be similarly contaminated.As genuine Zam Zam water cannot be legally exported from Saudi Arabia for commercial sale, any product found in the shops would have an uncertain provenance and pose a possible safety risk.
However, in May 2011, a BBC investigation found that, like the "fraudulent" Zamzam water being sold in 2005, genuine Zamzam water taken from the well also contained arsenic levels three times the legal limit.
In addition to the dangerous arsenic levels, the holy water contained high levels of nitrate and potentially harmful bacteria.
Dr Yunes Ramadan Teinaz, an environmental health officer who has previously warned about Zam Zam water, said it was "a sensitive matter".
"People see this water as a holy water," he added."They find it difficult to accept that it is contaminated but the authorities in Saudi Arabia or in the UK must take action," he said.
The BBC were also told that there are Muslims in the UK who drink nothing but Zamzam water.
Millions of Muslims drink Zamzam water every year. There is little doubt that many thousand, where possible, drink this water regularly and/or have fed their children and other loved-ones with it, thereby putting themselves and others at risk of the effects of arsenicosis, which includes cancer.
