Sep 12, 2016 The acceptable solution G12/AS1 requires that “components of the water supply system shall not contaminate potable water” (clause 2.1.1). Table 1 lists pipe materials for hot and cold water, and clause 2.1.2 states “Non-metallic components complying with BS 6920 or AS/NZS 4020 materials complying with Table 1 shall be acceptable.
The only way to detect the presence of heavy metals is through a water test. You may expect the today's town water supply is safe but here is a quote form NZ Ministry of Heaths web site: “About 1.1 million New Zealanders were supplied with drinking-water during 2003 that failed to comply with the current DWS2000 Standards”

The concentrations of aluminum in tissues of female New Zealand rabbits exposed to /aluminum oxide/ dust at a concentration of 0.56 mg Al/cu m for 5 months (8 hr/day, 5 days/week) were determined. The amount of aluminum in the brains of the animals was nearly two and a half times as high as that of the control animals.
Milk fat. Milk and cream are examples of fat-in-water (or oil-in-water) emulsions. The milk fat exists as small globules or droplets dispersed in the milk serum, Figure 2.15. Their diameters range from 0.1 to 20 µm (1 µm = 0.001 mm). The average size is 3 – 4 µm and there are some 10 10 globules per ml.
