Abstract: This is a descriptive cross- sectional study which was carried out at Elobied town in the period 2012 -2014 to assess the turbidity and residual chlorine of vended water quality. 55 samples were collected for analysis of turbidity and residual chlorine from vended water. The calculation of samples according to (1) samples per (10000) population, plus 10 additional samples (W.H.O 1993). Turbidity reached 90 NTU, The results illustrates high turbidity of vended water, where residual chlorine concentration was from (0.00 – 0.02 mg/l), which was not match with the W.H.O guidelines and SSMO (2007) recommend that the turbidity after treatment must be 5NTU or below. Time and Place Limitation: This study was carried out during 2012 to 2014 at Elobeied Town North Kordofan State - Sudan. Constrains: The natural constrains (Personal hygiene , Winds, rains and floods which affect in samples reading). Keywords: (Vended water - Turbidity – Treatment – Residual chlorine).
1. INTRODUCTION Vendors selling water to households or at collection points are common in many parts of the world where scarcity of water or faults in or lack of infrastructure limits access to suitable quantities of drinking water. Water vendors use a range of models of transport to carry drinking water for sale directly to the consumer including tanker trucks and wheelbarrows/trolleys (1). There are a number of health concerns associated with water supplied to consumers by water vendors; these include access to adequate volumes and concern regarding inadequate treatment or transport in inappropriate containers, which can result in contamination (W.H.O – 2008). Where the source of water is uncertain or the quality of the water is unknown, water can be treated or re-treated in small quantities to significantly improve its quality and safety. The simplest and most important treatment for microbial contaminated water is disinfection. If bulk supplies in tankers are used, sufficient chlorine should be added to ensure that a free residual chlorine concentration of at least 0.5mg/ liter after a contact time of at least 30min. is present at the delivery point. Tankers should normally be reserved for potable water use. Before use, tankers should be either chemically disinfected or steam cleaned. Local authorities should implement surveillance programs for water provided by vendors and where necessary, collection, treatment and distribution of water to prevent contamination (W.H.O – 2006). 1.1 Water scarcity: Water scarcity is a relative term; it depends on location, climate, season, and potential use by humans. The scarcity value of water is determined by the quality of water, the quantity of water, and the number and types of water users. It is greatly
