Water Analysis

S.I. 278 of 2007 Drinking Water Regulations defines two monitoring categories. These are Check monitoring and Audit monitoring.

Check Monitoring

Back to Top

The purpose of check monitoring is to regularly provide information on the organoleptic and microbiological quality of the water supplied for human consumption. Check monitoring also provides information on the effectiveness of drinking-water treatment (where used).

 Check Monitoring Parameter testing provided by the laboratory

Chemical Parameters	Microbiological Parameters
Aluminium	Clostridium perfringens (Note 2)
Hydrogen ion concentration [pH]	Escherichia coli [E.coli]
Ammonium ion	Coliform bacteria
Iron	Enterococci
Colour
Conductivity
Nitrite
Fluoride (Note 1)
Odour (Manual Check)
Turbidity

Note 1.  Fluoride is also included as a Check monitoring parameter if the water is fluoridated.

Note 2.  Only required to be measured if the water originates from or is influenced by surface water.

Audit Monitoring

Back to Top

The purpose of audit monitoring is to provide the information necessary to determine whether all the parametric values (concentration limits) specified in the Drinking Water Regulations are being complied with.

Audit Monitoring Parameter testing provided by the laboratory

Chemical Parameters	Chemical Parameter
Aluminium	Nickel
Ammonium	Nitrate
Antimony	Nitrite
Arsenic	Odour (Manual Check)
Boron	Selenium
Cadmium	Sodium
Chromium	Sulphate
Chloride	Total Hardness
Colour	Trihalomethanes – Total
Conductivity	Turbidity
Copper	Microbiological Parameters
Fluoride	Clostridium perfringens (Note 1)
Hydrogen ion concentration [pH]	Coliform bacteria
Iron	Colony count 22oC
Lead	Enterococci
Mangenese	Escherichia coli [E.coli]

Note 1.  Only required to be measured if the water originates from or is influenced by surface water.
