We will be constantly monitoring the area around the remediation site for air quality (dust, odour and chemicals called volatile organic compounds) and water quality, and noise for the life of the remediation project. Shortly, before soil excavation begins, we will be taking background monitoring readings to act as a baseline to compare with readings obtained during the works.

Once remediation starts in earnest, monitoring results will be regularly available to our site team so we can quickly adjust site activity to keep within agreed levels.

Odour can be a subjective issue but it is not one we take lightly. Unpleasant smells reminiscent of tar, creosote, mothballs, ammonia, antiseptic, marzipan and disinfectant are all likely to be noted at some point during the remediation. This is a direct result of disturbing the lagoon tars, which are rich in smelly hydrocarbons and other volatile organic compounds.

Some smells are inevitable, but we will be monitoring odour levels daily at the boundary, and then adjusting the working method to minimise the odour as much as possible. Our work team does not want to experience these smells either!

We will be installing an odour suppression system along the country park boundary with the treatment area for use when odours might be generated. The system will generate a fine mist or fog mostly composed of water. We will, from time to time, add an odour suppressant, which may smell like a fruit, typically strawberry or lemon to mask less pleasant smells. The odour suppressant is edible and does not cause any harm to the surrounding environment.

If the smell does become unpleasant, please let our site team know.
