B Wash 125 ml Amber glass or suitable bottles with a stopper with 2.0 M HCL or 2.0% nitric acid and rinse with purified water and dry the bottles at 105 ºC for at least one hour. Where potable (drinking water) water is stored, BS8558:2015 sets out a regime where 6 monthly microbiological activity is measured. Wrap the neck with aluminum foil to avoid any contamination during transportation. If sampling a body of running water, point the mouth of the bag upstream and your hands downstream to avoid contamination. Rinse the bag twice with the sample water prior to filling and closing.

A sample volume of 200ml should be sufficient for Faecal coliform, E. coli and Heterotrophic plate count. %���� Collect your water sample early in the week – Monday to Thursday –to give enough time to get to the laboratory and to be analyzed within 24-30 hours. Analyst error should be rare. The changes may occur in the bacterial content of water on storage can be reduced to a minimum by ensuring that samples are not exposed to light and are kept cool. It is important to routinely identify organisms recovered from water systems when: Waterborne organisms may be detrimental to finished products or processes in which the water is used. Hold the sterile container near the sampling point. Then remove the sterile strip from the bottle. SAMPLING FOR MICROBIOLOGICAL ANALYSIS In case of laboratory analysis for microbiological purpose, following guidelines are adopted to collect representative water samples: Sample Bottles Pre-sterilized sampling bottles of 200 ml capacity made of pre-sterilized disposible/autoclavable plastic, or good quality soda / borosilicate glass. endobj <> 4.1.16 Again collect the swab sample and repeat procedure following Point 4.1.1 to 4.1.13. 3 0 obj 2.

Unsatisfactory environmental condition e.g. Aseptic Technique for Microbiological Testing. Analyze the TOC sample as quickly as possible on arrival at the laboratory. for validated time. surroundings dusty, covered with debris, or poorly ventilated; 2. Sampling water for subsequent analysis is often considered to be somewhat easier than sampling, say, soils for two main reasons: (i) water tends to be more homogeneous than soils, there is less point-to-point variability between two samples collected within the same vicinity, (ii) it is often physically easier to collect water samples because it can be done with pumps and hose lines, (iii) known volumes of water can … Step Three Remove Faucet Screen and 3. 1.

Close the container immediately and record the sampling time. If you would like the entire volume, please send your email request for a zip file.. Sampling Procedures for Drinking Waters 1 PURPOSE This standard operating procedure outlines details for collection of drinking water samples for chemical, microbiological and radiological analysis. If the hose is not connected but is provided, attach the hose using procedures applicable for that system. 6.0 PROCEDURE FOR ANALYSIS OF WATER SAMPLE: Carry out the determination under conditions designed to avoid extrinsic microbial contamination of the water sample for the analysis. If a hose is not present, a sterilized adapter and hose may be used to sample directly from the valve/port. Sampling apparatus and containers shall be clean, sterile, and/or endotoxin-free as per test requirements. After completion of the test, record the results in the datasheet and also enter the results in the respective software/module. Prepare the sampling schedule (Tentative) by the first working day of every New Year. It is impractical to attempt the routine isolation of pathogens because they are present in relatively small numbers compared with other types of micro-organism. OBJECTIVE:To lay down a procedure for microbiological monitoring of raw water and purified water. Water quality — Sampling for microbiological analysis. If a hose is already connected to the port or valve, collect the sample directly from that hose. Details of the type of sample containers and preservatives to be used are also included. Unwrap the aluminum foil and open the bottle taking care not to touch the inner surface and neck of the bottle.
