Personal Protective Equipment must be worn at all times, visibility vests, protective footwear and gloves. 2. When sampling near water, life belts must be used and if possible two persons should carry out the sampling. 3. Easy access to and from the sampling location should be established before sampling commences. 4. Information regarding the location(s) of sampling and estimated time of return to the laboratory should be made available before departure from the laboratory. 5. Mobile phones should be carried at all times with contact numbers in case of emergency. 2:1 Introduction A monitoring programme should be pre-determined before the start of each sampling year. The programme should set out each point at which samples are to be taken for particular parameters, how many samples are to be taken at each point for each parameter and when the samples are to be taken. The programme should ensure that the number of samples taken at each wastewater treatment plant (WWTP) is distributed as evenly as practicable throughout the year. Samples collected in any monitoring programme must be representative of the quality of the bulk of the material being monitored. The act of collecting a sample must not alter the quality characteristics of the sample of the material collected for analysis from those of the bulk of the material from which the sample was drawn.

A written work list identifying all samples to be taken and identifying compliance and operational samples should also be present within the laboratory. 4 EPA Export 26-07-2013:23:37:05 3:3.2 Sampling Location Ensure that the sampling location will give a representative sample. 3:3.3 Calibration of automatic samplers 1. Automatic samplers must be calibrated on-site at each sample location before use. 2. Set the time interval dial on the panel inside the sampler to 1hr. 3. Set the volume dial on the panel to 300mls. 4. Place the end of the sampling tube into a 500ml graduated cylinder and press start. 5. Measure the volume lifted. 6. If the volume is greater or less than 300mls, reset the volume dial and repeat step 4. 7. Continue steps 4 to 6 until the sampler lifts a 300ml volume. 8. The automatic sampler is now ready for use. 3:3.4 Sampling 1. Ensure that proper sample bottles are used and that adequate volumes of sample are taken. 2. Ensure that sample bottles are labelled with the sample location, date and time, along with any other relevant information deemed necessary. Where applicable ensure that appropriate preservatives are placed in bottles used to collect samples. 3:3.5 Dispatch to Laboratory 1. The time interval between sampling and arrival at the laboratory must be the minimum practicable consistent with local logistical problems. 2. As a minimum samples should be held at less than 10oC while being transported to the laboratory. 3. On arrival at the laboratory samples should be logged in the sample log book and given individual identification numbers. These references numbers should be written on the sample bottles and used throughout analysis and recording of the sample. 4. Samples should be analysed For on inspection the day purposes of receipt only. at the laboratory wherever possible and refrigerated overnightConsent if too of copyrightlate for owner processing required for on any the other same use. day as sampling. 4.1 Bibliography Environmental Protection Agency (2003).

The following safety guidelines apply to individuals working within a laboratory environment. These guidelines are not intended to cover all aspects of safety: General Safety 1. Do not block exits or access to emergency equipment within the laboratory. 2. Do not smoke, eat or drink within the laboratory. 3. Keep work areas neat and clean within the laboratory. 4. Never pipette by mouth within the laboratory. 5. Wipe up spills promptly within the laboratory. Appropriate training in spill management should be obtained. (Hach, 2002) Protective Equipment 1. Wear safety glasses to protect eyes from flying objects or chemical splashes. 2. Wear gloves to protect skin from toxic or corrosive materials, sharp objects, very hot or very cold materials or broken glass. 3. Wear laboratory coats to protect skin and clothing from splashes. 4. Fume hoods should be used when directed to do so by the procedure, or as recommended in the material safety data sheet (MSDS). (Hach, 2002) First Aid Equipment and Supplies 1. First aid kits should be provided within the laboratory. Appropriate training in first aid should be obtained. 2. Eyewash and shower stations should be provided within the laboratory. 3. Fume hoods and appropriate fire extinguishers should be provided within the laboratory. Appropriate training in fire extinguisher use should be obtained. (Hach, 2002) Appropriate protective equipment should be worn when undertaking the BOD (Biochemical Oxygen Demand) electrode method. For inspection purposes only. Consent of copyright owner required for any other use. 2:1 Introduction The BOD electrode method is suitable for determining the BOD of water and wastewater. 2:2 Principle The BOD determination is an empirical test in which standardised laboratory procedures are used to determine the relative oxygen requirements of wastewaters, effluents and polluted waters (APHA, AWWA and WPCF, 1985). The test measures the oxygen required for the biochemical degradation of organic material (carbonaceous demand) and the oxygen used to oxidise inorganic material such as sulphides and ferrous iron.
