Feedback from PUB on NO3, PO4, Ca/Mg ratio

[PeterGwee]

Okay...Geoffrey, finally manage to squeeze some info out from my colleagues from other department.

Dear Mr Peter Gwee

Our water supply is classified as "Water from Choa Chu Kang and Bedok
Waterworks" and "Water from Other Waterworks". As requested, the
information on potable water quality (Typical Values) is appended
below:

                    Water from Choa Chu Kang    Water from Other Waterworks
                                                  and Bedok Waterworks

                              mg/l                       mg/l        

Nitrate (as NO3)              0.5-7.0                   0.5-15.0
phosphate (as PO4)            <0.10                     <0.10
Calcium (as Ca)               <50                       <50
Magnesium (as Mg)             <10                       <10

Currently, only a small amount of NEWater is being added in the
reservoirs.
We do not observe any change of the mineral contents in the reservoirs.

Why need to squeeze? The infomation is readily available on the net.
Nothing new.
