15 1. OBJECTIVES 15 The Philippine National Standards for Drinking-Water of 2017 aims to protect public health by prescribing standards and procedures for drinking-water.

16 2. SCOPE AND COVERAGE 16 The 2017 PNSDW is applicable to all drinking water service providers including the following: Government and private developers and operators of water supply systems Bulk water suppliers providing drinking-water Water refilling station operators Water vending machine operators Ice manufacturers All establishments and institutions that supply or serve drinking water Drinking water testing laboratories Health and sanitation authorities General public All others who are involved in determining the safety of public s drinking water

17 3. GENERAL GUIDELINES 17 1) Standards for drinking-water quality, water sampling and examination and evaluation of results shall conform to the criteria prescribed under this Order and its Manual of Operations. 2) To ensure the safety of drinking-water, the standards shall be applied in accordance to the improved framework for drinking-water safety.

18 Standards for Other Modes of Distribution of Drinking-water 18 Drinking-water from refilling stations, vending machines, mobile tanks and bulk water supply o initial and periodic examinations for microbiological, physical, chemical and radiological quality.

19 Evaluation of Results Expression of Results Microbiological examination for drinkingwater Physico-chemical and radiological examinations for drinking-water 19 Interpretation of Results Drinking-water service providers shall consult the DOH/LDWQMC/local health

20 4.6 Classification of Drinking-water Parameters 20 MANDATORY PARAMETERS 1. Thermotolerant Coliform / E. Coli 2. Arsenic 3. Cadmium 4. Lead 5. Nitrate 6. Color (Apparent) 7. Turbidity 8. ph 9. Total Dissolved Solids 10. Disinfectant Residual (See Page 25) PRIMARY PARAMETERS 56 Parameters (See page 26) Site-specific Enforceable parameters Can be adopted by the LDWQMC SECONDARY PARAMETERS 11 Parameters (page 26) Parameters that render the water unacceptable for drinking Operational parameters which affect the efficiency of the treatment processes

21 Classification of Drinking-water Parameters SECONDARY EMERGENCY DRINKING- PARAMETERS WATER PARAMETERS Parameters that render the water unacceptable for drinking Operational parameters E. coli. which affect the efficiency of the treatment processes Residual chlorine, and SUSTAINABLE DEVELOPMENT GOAL PARAMETERS Relative to Target of the SDG in achieving universal and equitable access to safe and affordable drinking water for all by 2030, the population should be using safely managed drinking water services 21

22 Water Safety Plan (WSP) and Drinking-water Quality Surveillance 22 The implementation of WSP approach can secure the safety of drinking-water. The WSP shall be developed to meet health-based targets consistent with the Philippine National Standards for Drinking Water.

23 RESPONSIBILITIES 23 ROLES AND Local Government Unit Enforce the provisions of this Order Develop and implement drinking water quality surveillance program

24 ROLES AND RESPONSIBILITIES 24 Water Laboratory Comply with the provisions of this Order Secure accreditation from the Department of Health Implement QS and develop a manual of operations describing the laboratory s policies and plans for ensuring the quality of their work provided to the public
