2006/7 – Trentham (Victoria) – Formaldehyde

2006/7 – Trentham (Victoria) – Formaldehyde 0.5mg/L (maximum detection)

Guideline: Based on health considerations, the concentration of formaldehyde in drinking water should not exceed 0.5 mg/L.
GENERAL DESCRIPTION
Formaldehyde may be present in drinking water through ozonation of naturally occurring humic material, contamination by accidental spills, or deposition from the atmosphere. Typical concentrations in air are probably in the low parts-per-billion range. Overseas, formaldehyde has been detected in ozonated drinking water at concentrations up to 0.03 mg/L.
Formaldehyde is used industrially in the wood, paper and textile industries. It is also used in the production of a number of chemicals and for the preservation of biological material. It is occasionally used as a disinfectant, sometimes to disinfect water filters. Other sources of exposure include cigarette smoke and food. Formaldehyde is present in almost all common foods, and adult dietary intake is estimated at 11 mg/day. Drinking water would contribute less than 10% of total intake.
