A/HRC/42/47/Add.4 standards (total faecal coliform bacteria or Escherichia coli). Regarding physical and chemical parameters, out of 727 samples, 55.6 per cent were outside the norm, especially regarding the lack of residual chlorine (A/HRC/33/49/Add.1 paras. 58, 59 and 62). 39. PLANAPS outlines a total investment matrix for measures to monitor the quality of all water sources used for human consumption (surface waters and ground water) and for monitoring household wastewater disposal. Furthermore, PLANAPS states that operators will be responsible for the establishment of monitoring and surveillance networks for this water, perimeters of protection for 1,200 wells, 6 deviation canals for water sources intended for human consumption, and for operating costs for the monitoring networks. Such measures have been included in the Service Provider Support and Strengthening Plan. 40. The Government referred to the 2018 regulation on “Water. Water for human consumption. Quality, and safety requirements”, which aims to establish permissible parameters which water for human consumption must fulfil and is applicable to any natural or legal person providing or managing a water provision system for human consumption. Furthermore, the regulation states that water providers shall conduct basic, intermediate and complete analysis according to the parameters and set and keep records for verification by health authorities. According to the Government, the drafting process of the aforementioned regulation included an international consultation and the participation of representatives of the institutions, private sector, water councils or municipal development associations, among others. Furthermore, MINSAL and ANDA are in charge of implementing the Water Safety Plans for Rural Systems, the objective of which is to ensure continuous access to safe water of sufficient quality. Water Safety Plans for Rural Systems are developed with the participation of the Management Councils of Rural Aqueducts, which are composed of residents and water users from communities. Finally, the Government mentioned that ANDA supports rural communities in performing bacteriological water testing and in ensuring water quality, and additionally, provides training to water system operators. 41. The Special Rapporteur welcomes efforts made by the Government to set water quality requirements and water safety plans, taking into account rural water systems specifically and that PLANAPS outlines an investment matrix to monitor the quality of all water sources used for human consumption. He also notes efforts made by the authorities to involve relevant stakeholders in the preparation of such instruments and the training provided to communities and operators in monitoring water quality. While plans to invest in water quality monitoring and to set participatory monitoring authorities are a solid basis for achieving compliance with drinking water quality requirements, specific measures to allocate resources to implement such plans need to be adopted. Most importantly, improvement of the quality of drinking water, protecting water sources and implementing adequate water treatment plants, are essential to ensure compliance with set standards. Accordingly, the Special Rapporteur encourages the Government to continue the positive developments it has taken and to invest and adopt measures for moving towards both a monitoring system and an improvement of drinking water quality, which will help ensure the protection of human health of all segments of the population. GOOD PROGRESS: The Special Rapporteur encourages the Government to continue investing in the implementation of monitoring systems in order to ensure that these effectively guarantee that safe drinking water is provided to the whole population. D. Recommendation on water quality assessment RECOMMENDATION 11: “Conduct a critical assessment of the impact of environmental and agrochemical pollutants and of interruptions in water supply on the quality of water for human consumption and of the risks to health.” (A/HRC/33/49/Add.1, para. 96(i)). 42. The Special Rapporteur pointed out in his country visit report that a considerable proportion of surface waters were polluted, essentially from untreated urban wastewater and agriculture or industry runoffs. The Special Rapporteur quoted the example of The Acelguate River, which drains the metropolitan areas of the capital and was severely 11
