2. (a) The supply was derived from the following works and pumping stations:-
The higher ground around Muswell Hill is supplied with River Thames-derived water. The remainder of
the borough is supplied with New River-derived water. During the summer months, the Northumberland
Park area receives well water from Park pumping station.
No new sources of supply were instituted and there were no changes to the general scheme of supply in
your area.
The number of samples collected and the bacteriological and chemical analyses of the supply from the
above sources after treatment are shown on the attached sheets.
(b) On account of their hardness content and alkaline reaction the Board's river and well water supplies are
shown to be not plumbo-solvent. It should, however, be appreciated that all types of water pick up varying
amounts of metal from the material of water piping particularly when it is newly installed; this
applies to copper, zinc, iron and also to lead.
