If you are planning to develop a site your first step should be to get a Phase 1 desk study of the site carried out by an environmental consultant. A Phase 1 desk study involves the collection of as much historical data on a site as practical, then interpreting the information to form a conceptual site model of the site. After the Phase 1 desk study, you will have an idea of what you may find on the ground which helps in site investigation design and likely contamination of soil and water remediation in Sunshine Coast requirements.
Ways to Speed up Bioremediation
- It is important to aerate the soils because the more air you can get into the soils, the greater the rate bacteria can respire and the greater the rate of contaminant degradation.
- You can also physically turn the soil as that result in physical attrition of contaminants, another benefit in reducing contaminant concentrations.
- Producing the right balance of nutrients will speed up the remediation process.
- Bacteria require moisture to do their job, too much moisture and you starve them of oxygen, not enough and you don’t get the most out of them so you need to balance moisture.
- You should maintain a working temperature in the soils. You can carry on bioremediation in large piles (bio-piles) to give an insulating effect which will keep the core of the bio-pile warm. Sheeting the pile with ‘fleeces’ keep the warmth and the moisture in the bio-pile.
- Add contaminant specific bacteria but be a little cautious about this approach, sometimes it works and sometimes it doesn’t. Adding new bacteria can produce great results, assuming they survive. Soil conditions have so many variables including pH, and metal mixtures and few bacteria can stand up to the test of being introduced to a new soil.
Need for Soil Remediation
Soil remediation, from an environmental perspective, is the reduction of contaminant concentrations within the soil. The aim for soil and water remediation in Sunshine Coast in most cases is to reduce contaminants to levels suitable for use and also to reduce environmental risks. Soil remediation treatments including bioremediation, chemical oxidation etc. and are all carried out to reduce contamination to acceptable levels.
