Water Quality West Perth

[cubbie]

Hi I just got the water quality data for my address so thought I may post it up for others that are interested. I live in West Perth which is supplied from the Mt Eliza system.

I am the Beatty Park side of West Perth, don't know if that makes a difference.

Now I just have to work out what the data means. I have never adjusted my water profile or tested/adjusted my ph so it is time to learn about this.



Minimum, Maximum, (1987 NHMRC/AWRC guideline value)

pH 6.9, 8.2, 6.5 8.5
Conductivity (mS/m) 25, 125, None
Colour (HU) <1, 5, 15
Turbidity (NTU) <0.1, 2.0, 5.0
Sodium 110, 170, 300
Potassium 3, 7, None
Calcium 9, 35, None
Magnesium 5, 10, None
Hardness as CaCO3 50, 125, 500
Chloride 150, 250, 400
Sulphate 15, 40, 400
Alkalinity as CaCO3 45, 135, None
Nitrate + Nitrite as N <0.05, 0.65, 10.00
Iron 0.02, 0.30, 0.30
Manganese <0.002, 0.055, 0.100
Aluminium <0.008, 0.095, 0.200
Silica as SiO2 6, 16, None
Total Filterable solids (by sum) 390, 570, 1000

Yep it looks like your average print out = many variables depending on which one you choose to use on the day.We all have the same problem, government speed sheets.LOL

It's similar to mine, which is hardly surprising since I'm only a few kms away.

It's basically low in everything except sodium and chloride, so it's soft but salty.

Here's a good place to start reading - link.

Hey Cubbie, I'd wondered where you had gone ! Are come coming to the Sandgropers Chrissy Case Swap ?
Anyways, to vaguely get back on topic here are the specs for Bibra Lake, as already stated the supply is blended from different sources so there are many variables from day to day.

The Water Corporation regularly monitors the quality of all drinking water supplies to ensure that water supplied to consumers is both safe and pleasant to drink.

The report below shows the range of analysis results for water sampled from the reservoir outlet and the distribution system over the past two years.

As water sources are developed or operational changes are made, variations in water quality are always possible. This report should, therefore, only be regarded as an indication of the water quality that would be expected in this area.


Typical Range 1987
NHMRC/AWRC guideline value
Minimum Maximum
pH 6.8 8.8 6.5 8.5
Conductivity (mS/m) 25 40 None
Colour (HU) <1 5 15
Turbidity (NTU) <0.1 1.2 5.0
Sodium 25 40 300
Potassium 1.0 1.2 None
Calcium 10 25 None
Magnesium 2 5 None
Hardness as CaCO3 50 75 500
Chloride 45 70 400
Sulphate 5 15 400
Alkalinity as CaCO3 10 55 None
Nitrate + Nitrite as N <0.05 0.07 10.00
Iron 0.004 0.2 0.300
Manganese <0.002 0.03 0.100
Aluminium 0.01 0.11 0.200
Silica as SiO2 5 8 None
Total Filterable solids (by sum) 160 205 1000


Total Filterable solids - high levels impact the taste to the water.
Alkalinity - of interest to pool owners, aquarium keepers.
Turbidity - high levels cause cloudiness in water.
Iron and Manganese - excessive levels contribute to brown staining / discolouration and dirty water problems
Colour - due to contact with vegetation in the catchment
Hardness - high levels can cause scaling on heating elements and difficulty in producing a lather.
Fluoride - added to water as required by State Government legislation at concentrations between 0.7 mg/L and 1.0 mg/L.


The program also includes toxic metals, synthetic organic compounds and microbiological monitoring, the results of which comply with the requirements of the 1987 NHMRRC/AWRC Guidelines for Drinking Water in Australia.
