A/HRC/6/3 page 19 IV. MONITORING 43. Relevant mechanisms for the monitoring of human rights obligations in relation to access to safe drinking water and sanitation include the following: (a) United Nations treaty bodies: several treaty bodies, including CESCR, the Committee on the Rights of the Child, the Committee on the Elimination of all Forms of Discrimination against Women and the Committee on the Elimination of Racial Discrimination have addressed access to safe drinking water and sanitation in their review of States parties’ reports and have formulated specific recommendations thereon. Their concluding observations shed light on some key concerns, e.g. on issues related to lack of water in slum areas, lower standards for minorities, restrictions regarding access, the situation of IDPs, water pollution, environmental problems and their impact on access to water, imbalances in water supply between urban and rural areas, the failure of States to ensure the supply of safe drinking water to vulnerable groups such as children, restrictions on access to water for persons living under foreign occupation, and cases where large segments of the population are left without safe drinking water;59 (b) Special procedures of the Human Rights Council: several special procedures have looked at the relevance to their mandates of the issue of access to safe drinking water and sanitation. In particular, the Special Rapporteurs on the right to food and to the highest attainable standard of physical and mental health and the Special Rapporteur on adequate housing as a component of the right to an adequate standard of living have dedicated attention to the issue during their country visits and in individual communications and annual reports. The Special Rapporteur on the right to health has considered safe drinking water and sanitation as determinants of the right to health, while the Special Rapporteur on adequate housing as a component of the right to an adequate standard of living has analysed these issues within the context of accessibility to services.60 In 2001, the Commission on Human Rights asked the Special Rapporteur on the right to food to pay attention in his reports to the issue of drinking water and its interdependence with the right to food;61 59 See for instance CESCR concluding observations on Azerbaijan (E/C.12/1/Add.20, paras. 23 and 37), Bolivia (E/C.12/1/Add. 60, para. 13), Cameroon (E/C.12/1/Add.40, para. 22), Canada (E/C.12/1/Add.31, para. 17) and China (Hong Kong) (E/C.12/Add.58, para. 6). 60 See the contribution of the Special Rapporteur on the right to the highest attainable standard of physical and mental health to the High Commissioner’s study available at http://www.ohchr.org and also his reports on missions to Peru (E/CN.4/2005/51/Add.3, paras. 10, 15, 19, 54, 62, 63) and Romania (E/CN.4/2005/51/Add.4, para.73). See also the reports of the Special Rapporteur on adequate housing as a component of the right to an adequate standard of living (E/CN.4/2002/59, paras. 49-65, E/CN.4/2003/5, paras. 39-46, E/CN.4/2006/41/Add.2, para. 105 and A/HRC/4/18, annex II). 61 See E/CN.4/2001/25, para. 21, A/56/210, paras. 58-71 and E/CN.4/2003/54, paras. 36-51.
