Growing food in contaminated soil carries many risks with it. There are areas in Sydney with greater risks of soil contamination than other sites. Therefore, before putting your land into any form of use, it is important to carry out an environmental investigation to understand the history of the soil and determine whether it can pose any health risks.

According to the Sydney Morning Herald, the chemicals found in the backyard soil of many inner city homes, particularly lead, increasingly directs to sickness and even brain damage to children. Traces of these may emerge from old paints, chemicals used in the house, or surrounding factories.

As most risks emerge from the greens grown in vegetable patches or community gardens, soil contaminants can also be found in areas such as Balmain, Surry Hills, and even Marrickville. However, given that very few Sydney residents are able to understand the soil history in their backyards, it is very important to invest on a reliable soil contamination testing Sydney service.

The soil contaminants do not just affect humans by means of growing food in vegetables patches or community gardens. During the dry summers, the poisonous lead chemical and arsenic contaminants in the soil can spread through small dust particles.

Children are mostly at risk from these contaminants as they absorb as much as 60% of ingested lead compared to adults who absorb only 10% of this. Thus, the effects on the overall health of children can be perilous.

If your backyard garden is located close to old industrial enterprises, landfills, or busy roads in Sydney, then you urgently need some contamination testing Sydney services.
