1 ENVIRONMENTAL MANAGEMENT BUREAU DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES WATER QUALITY MONITORING MANUAL VOLUME II MANUAL ON effluent QUALITY MONITORING February 2008 Water Quality Monitoring Manual VOLUME II Manual on effluent Quality Monitoring PREFACE This manual on effluent Quality Monitoring (EQM) constitutes VOLUME II of a two- VOLUME manual on Water Quality Monitoring, VOLUME I being the manual on Ambient Water Quality Monitoring (AWQM). VOLUME II is a guide to monitor the quality of effluent from industries and other regulated wastewater dischargers. The objective is to standardize effluent quality monitoring procedures to ensure that the water quality monitoring programs follow certain Quality Assurance/Quality Control (QA/QC) protocols and acceptable field methods.

2 The primary users of the EQM manual are the technical staff of the EMB, both the Central and Regional Offices. Other users may include the technical staff of LLDA and other agencies or individuals under the DENR. Users may also include other government regulators and implementers, consultancy firms, industries, monitoring groups such as Multi-partite Monitoring Teams (MMTs), students and researchers. The manual is intended to be a dynamic document that will be periodically reviewed and updated as deemed necessary. i Water Quality Monitoring Manual VOLUME II Manual on effluent Water Quality Monitoring Elsie B.
