 Most water quality analyses cannot be done on site
 Microbiological Quality
 Physical Quality
 Chemical Quality

5.  the presence of organisms that cannot be individually seen by
the naked eye, such as protozoa, bacteria and viruses
 associated with the infectious water-borne diseases such as
gastroenteritis and cholera

6.  Refers to water quality properties (such as conductivity, pH
and turbidity)
 The physical quality mainly affects the aesthetic quality
(taste, odour and appearance) of water.

7.  the nature and concentration of dissolved substances (such as
organic and inorganic chemicals including metals).
 certain concentration most chemicals (e.g. zinc, copper,
manganese) may have negative health effects.

8. Planning A Sampling Event
A sampling event is important and will save time and reduce the
number of difficulties

 Logistics
 Communication
 Equipment
 Occupational health, safety and welfare

9. Logistics (Basic Steps)
 Review the monitoring plan
 Inform the client or property owner
 Discuss any problems
 Planning how and when will transport the samples back
to the laboratory
 Check all the equipment required and test
 Fill out as much paperwork before sampling

10.  Need to get consult from laboratory

11.  Paper work and record keeping
 Navigational aids
 Field testing meters
 Sampling containers
 Decontamination of sampling equipment
 Esky or refrigerator
 Camera
11June 23, 2016

12.  Including sampling plan or schedule and map
 Field Record Sheet
 Other requirement paperwork (labels)

14. Navigation Aids
 Important to be able to accurately locate the sampling
site for future reference
 Global Positioning System(GPS) can be used
 Sampling Location be recorded on site map

15. Field Testing Meters or Field
Measurement
Following be measure in situ
• Dissolved oxygen(DO)
• Temperature
• Conductivity
• Redox (reduction/oxidation potential)
• Trubidity
• chlorine

17. Sampling Containers
 Wrong sampling equipment can affect the integrity of
the sample
 Important to use appropriate containers for each
various parameter

22. Decontamination of sampling equipment
 Should be thoroughly cleaned
 Include detergents, ethanol, scrubbing brushes, tap
water, distilled water
 10% of sodium hypochlorite solution for microbiological
samples
22June 23, 2016

23. Camera
 Most type of samples required chilling
 Can be stored in esky or car refrigerator
23June 23, 2016
Esky or refrigerator
 Photo can show where simple taken and illustrate
record on the field datasheet

24. Typical hazards in the sampling include
 Vehicle breakdown or accident, bogging in wet condition
 Exposure to hazardous sample preparation
 Temperature hazard, typically sunburn and heatstroke
 Poisonous animals and plants
Also emergency procedures need to prepare
