3. For oil and grease, collect the water into 1Liter clean, glass amber containers.
B. Bacteriological Testing
Sampling preparation
For metal taps, use a propane or butane burner to disinfect by flaming
1.1 Turn tap on and leave it to run for two to three minutes. Then turn tap off.
1.2 Flame thoroughly staring at the top nozzle end working backwards. Water in spout should boil.
1.3 Methylated spirit flames are not hot enough and are difficult to control.
1.4 After flaming, turn tap on and leave to run for two to three minutes until water is cool.
Collecting the water in a sterilised bottle
2.1 Adjust flow to generate steam. Hold in hand and remove bottle cap with another hand. Do not put cap down. Allow bottle to fill to shoulder.
2.2 Never rinse out the bottle
2.3 Replace cap tightly and shake the bottle
2.4 Place the bottle in a cool box and deliver to the laboratory promptly (within four hours)
3. For plastic taps or where flaming is not permitted, use 10 percent sodium hypochlorite solution,
Waterguard or JIK solution (1 percent available chlorine).
3.1 Remove any external fittings, grease or slim with a clean swab.
3.2 Turn tap on and leave it to run for two to three minutes.
3.3 Disinfect inside and outside of tap by swabbing with 10 percent sodium hypochlorite solution
3.4 Alternatively use a wash bottle filled some sodium hypochlorite, spray the outside and inside of the tap spout
3.5 Wait for two to three minutes to allow sodium hypochlorite or disinfectant.
3.6 Turn tap on and leave to run for five minutes to remove all disinfectant.
3.7 Collect sample as in step 2.1 to 2.4
