Hi all, hoping someone can help me out with my issue. I am currently writing up an SOP on testing the potable water that we use on site. what I need to know is do I only have to test for coliforms or do I need to test for e-coli as well. I'm also not sure of the levels of acceptability or if the results are out of range is there a regulatory that I have to notify or is it just our customers. I am in Australia and we use straight town water without using a holding tank.

Cheers Carol

Hi Carol88,

 

Try http://www.iwa-netwo...delines/003.pdf

 

Part III Monitoring

Chapter 9 Overview of Monitoring (Revised 2011)

Including Table 9.1 Examples of operational monitoring characteristics

(distribution system monitoring is most relevant)

Monitoring Escherichia Coli (E. Coli)/Total Coliforms/Heterotrophic Plate Count (HPC)


 

Also see 3.5.4 Corrective action

(In case of a positive, inform supplier and clean/disinfect site water distribution system comes to mind).

 

If you have plenty of spare time then the following may also be of interest:

Part II Chapter 5 Microbial Quality of Drinking Water

Part V Fact Sheets Microorganisms, Microbial indicators

 

Some far simpler info here also:

Kind regards,

Dear Carol 88
Im my country, there is a set of regulatory parameter to check on, which include:
Physical standard: pH, colour, turbidity

Chemical standard: aldrin/dieldrin, Aluminium, ammonia, anionic detergent, antimoni, arsenic, barium, biocides, bromodichloromethane, bromoform, boron, cadmium, carbon chloroform extract, chlordane, chloride, chromium, chloroform, chlorpyrifos, copper, cyanide, 2,4-D, DDT, dibromochloromethane, endosulfan, fluoride, hardness, heptachlor & heptachlor epoxide, hexachlorobenzene, iron, lindane, lead, manganese, magnesium, mercury, methoxychlor, mineral oil, nikel, nitrite (calculate as NO2 -, NO3 -, N), phenol, residual chlorine (free), selenium, silver, sodium, styrene, sulphate, zinc.

Microbe standard:
Total coliform, e.coli, fecal streptococci, pseudomonas aeroginosa, clostridium perfringens, sulphite reducing anaerob.

Radioactivity:
Gross α
Gross β

Besides fulfill your own country requirements, you need to fulfill exporting country requirements as well.

Testing frequency for full set of above is yearly, in my experience.

Additional test on physical standard, total chlorine, residual chlorine, total coliform, e.coli depend on your risk assessment.

Hope it helps.
