This guide manual on water and wastewater analysis prepared by the Central Pollution Control Board (CPCB), caters to the need of evolving a simplified code of practice for the laboratories engaged in carrying out water quality assessment under the Hydrology Project-II implemented by the Ministry of Water Resources (MoWR). Proper venting of muffle furnaces and drying ovens. Each analyst must analyze a laboratory-fortified blank and laboratory-fortified blank duplicate sample set (LFB/LFBD) to demonstrate . II. If sampling a body of running water, point the mouth of the bag upstream and your hands downstream to avoid contamination. Many areas of wastewater treatment involve certain potential hazards and the analytical laboratory is certainly no exception. If sampling from a water faucet, run the faucet for 1 minute before obtaining a sample. Wastewater or sewage is the byproduct of many uses of water. The wastewater is then pumped from the wet well.

Therefore, proven, state-of-the-art techniques of chemical analysis, properly employed, are essential to environmental chemistry. BOD is based on the principle that if sufficient oxygen is available, aerobic biological decomposition (i.e., stabilization of organic waste) by microorganisms will continue until all waste is consumed. 1989. Proper Handling And Preservation Of Water Samples I. Key Points: Microbiological water testing looks for indicator organisms as a sign of faecal contamination rather than testing for specific pathogens. The essential tasks and capabilities that were identified through this process are called the core competencies.
