How to Interpret Your Water Analysis Report


If you have a private water supply (not mains supply) then you will require to have a water analysis carried out at regular intervals, so as to ensure that your supply is wholesome and that any problems can be addressed with the installation of appropriate water treatment filters.


Firstly, we would need to obtained water samples direct from the source, these are collected in specially treated containers and sent off to an accredited laboratory for analysis.  Very few laboratories provide explanations of the test results beyond obviously stating which parameters have failed.  This is where we come into the equation; we will provide an explanation of the failed contaminants and suggest filters to treat specific problem areas.


What do the figures mean?


Once you receive your report it will list parameters tested for (contaminants) which will show the result and maximum admissible concentrations values (MAC) permitted.  Any reading above the MAC will indicate a failure.  These MAC’s have been established by the EC Drinking Water Directive which has determined what safe levels of contaminants in drinking water are.


Remember pure water does not exist as nearly all water contains some form of contaminants.  In most instances these contaminants are minimal, however where they are excessive they can cause a real problem and be harmful to health.


Which Contaminants Should I be Concerned With


The list of contaminants is vast however we principally have to be concerned with the following:


Presumptive Coliforms - are a bacteria present in air, soil and vegetation.  The presence of coliforms could indicate the presence of faecal contamination from sewage and/or animal waste.


E.coli – is a bacterium found in the gut of warm blooded animals and if detected in water indicates the presents of faecal contamination from sewage and/or animal waste.


pH Value – is an important measurement of water quality, 7 is neutral, below 7 is acidic which can cause corrosion and above 7 is alkaline which can cause scaling.


Iron (Fe) – An element found dissolved in ground water in the form of ferrous iron.  High concentrations are an unacceptable nuisance causing staining, bad taste and odours.


Manganese (Mn) – An element found dissolved in ground water and often associated with iron.  Causes black staining and poses similar problems as with Iron.


Hardness - a natural characteristic of water due to the presence of calcium and magnesium.  Causes deposits and formation of scale on household appliances and heating systems.


Turbidity – a cloudy condition of water due to suspended silt or organic matter.


Nitrates as NO3 – occurs naturally in most water sources; however, concentrations can increase due to fertilizers in agricultural use and animal waste leaching into the groundwater.  Can be harmful for children and animals.


Taste and Odour – this is the aesthetic quality of water often associated with other contaminants.


Lead as Pb- this element if rarely found in groundwater however can leach into water supplies by use of lead pipe and fittings, soldered joints, petrol and batteries.  The permissible levels have recently been changed from 25 to 10 microg/l.


Copper as CU – this element is rarely found in groundwater however can leach into the water supplies by water passing through copper pipe work, often as a result of acidic water better known as Cuprosolvency.


Sodium as Na and Chloride as Cl – are salts found in most water sources and can be dangerous in high concentrations.


Sulphate as SO4 – is found naturally in most groundwater sources and is a major dissolved component of rainwater.  High concentrations can have a laxative effect when combined with calcium and magnesium.
