Chemical safety of drinking-water: Assessing priorities for risk management
This text provides guidance on the chemical safety of drinking-water. Chemical contaminants of drinking-water are often considered a lower priority than microbial contaminants, because adverse health effects from chemical contaminants are generally associated with long-term exposures, whereas the effects from microbial contaminants are usually immediate. Nonetheless, chemicals in water supplies can cause very serious problems. The objective of this text is to help users at national or local level to establish which chemicals in a particular setting should be given priority in developing strategies for risk management and monitoring of chemicals in drinking-water. The document will be useful to public health authorities, those responsible for setting standards and for surveillance of drinking-water quality, and to water supply agencies responsible for water quality management. In particular, this publication will be applicable in settings where information on actual drinking-water quality is limited, which is the case in many developing countries and in rural areas of some developed countries.

WSP summary of benefits and costs
Before implementation of a WSP it is important to clearly identify the expected benefits and the associated costs both of which could be significant. This will help secure the support of senior management, ensure that sufficient resources are made available and allow much more targeted and efficient implementation. The actual benefits and costs of WSP implementation will vary considerably from utility to utility. This document sets out a summary of the issues that need to be taken into account.

A guide to conducting household surveys for Water Safety Plans
The aim of this manual is to provide guidance on conducting a household survey as part of a Water Safety Plan for organized piped water supply systems in resource-limited settings. A household survey can help researchers to understand the fate of water from the time it reaches the home to the point of consumption. This survey contributes to Module 2 (System Assessment) of the Water Safety Plan, upon which the subsequent steps of hazard identification, consideration of control measures, and development of corrective actions, monitoring, and verification plans are based. Thus, the survey provides valuable information for the WSP team as the team goes through the process of system evaluation and implementation of changes resulting from the Water Safety Plan. Specific examples intended to guide the planner in designing the survey are provided in the appendices. A summary checklist for survey planning and completion is provided as Appendix A.

Water Safety Plans for communities: guidance for adoption of water safety plans at community level
Numerous publications now exist on the formation and use of WSPs, but most of these focus on largerscale projects run by private or public utilities, commercial enterprises and international NGOs. Tearfund’s particular interest is in how WSPs can be understood and established by user communities which are faced with self-managing a water supply project to gain sustainable access to safe water quality. The guide is written chiefly for the use of a facilitator or facilitating body (eg the hygiene promoters or community mobilisers of a DMT or partner staff) to use in training community members, and in particular,the water project accountability group (eg Water Users Committee) of the community.
