Microbiological and Chemical analysis for some metals In water circulated in Riyadh Like Zamzam Water

This study aimed to determine microbic contents and chemical analysis for some basic metals and non basic metals (heavy) and non metallic compounds such as nitrite in water circulated in Riyadh via small trucks or small commercial shops dealing in vegetables of species, this water are to be sold in 6 gallons, plastic packages of 10 liter.
Laboratories of ministry of water and electricity and IDAK laboratories were asked for aid, also Saudi standard specifications of water were used, as well as water specification issued by international health organization for comparison, also it was referred to a previous analysis take place in 1426 H at laboratory of water and electricity for Zamzam Water from a basic resource in Mecca (In previous research for the researcher) was transferred to Riyadh inside a steriled package of capacity (3.8 liter) and putting ice bags.
According to international health organization method to take samples (1988) to analyze at the ministry's  laboratory) this research proved that Zamzam's water was free of and colon bacteria but the Nitrite percentage were very high, where water content circulated via traveling salesmen reached 128.5 mg/L and water sold at commercials shops 128.8 mg/ L it is clear that there is  no significant difference between them, by comparing water circulated in commercial shops with water refined in ministry of water and electricity we found that it reached 59.0 mg/ L near to Saudi Specification and center national organization specification which determined a percentage of 50 mg/L as a maximum allowable percentage where the nitrites percentage of the analyzed water from it's main source in Mecca in 1426 H Reached 7.0 mg/L
Also this packages lack any guide card and subjection to food and water control supervision, also workers have no proof regarding acquiring any medical examination certificate and they seem careless and un clean persons
The researcher suggests the importance of establishing a supervision committee to make sure of this water quality and analyzing it
Also she suggests establishing a factory supervised by a governmental body reliable for packaging Zamzam water according to healthy conditions to guarantee safe manufacturing, transport and storage and guarantee reaching to consumer in other cities at low prices.
