We were tasked with completing phase 1 desktop studies for 19 sites throughout Haringey.
Sanctuary Group were in negotiation to obtain a number of infill sites of various size and condition for residential development.
Within a very challenging time frame a phase 1 environmental report was completed for each of the 19 sites with advice on the phase 2 intrusive investigation required to determine the extent of any potential contamination on the identified sites.

To investigate the soil in the gardens on an estate following complaints from residents of poor plant growth and adverse impacts on the health of pets.
The houses were situated on a “T” shaped cul-de-sac, each with a private garden. A previous visual investigation had been undertaken and report prepared by others following tenants raising concerns regarding builders’ rubble found in their gardens and poor plant growth. Go Contaminated Land Solutions reviewed the previous investigation and undertook sampling to assess the site conditions using a mix of boreholes and shallow trial pits. A drive-in sampler which could be carried through the properties was used to form the boreholes.
In many of the gardens pieces of builders’ rubble protruded above ground, in one the end of a scaffold pole was visible and in another a whole pre-cast concrete edging was found. It would appear that over time rain had washed the original thin dressing of topsoil down into the voids between the underlying rubble.
The samples were tested for a typical range of metals, hydrocarbons and polycyclic aromatic hydrocarbons. While no elevated levels of contaminants were identified the soil was found to be of a poor quality as a growing medium and advice was provided on improving the soil quality so that the residents could enjoy the proper use of their gardens.

Provide advice on an area within a residential estate that was proposed for use as a community allotment.
The site was located on the Isle of Dogs, not far from Mudchute Farm, in an area with a long industrial history. Previous investigations had identified some contamination to be present. Our report considered a range of options from further sampling and testing including the possibility of testing for bio-accessibility to providing means of mitigating the risk by the use of raised planters or for fruit trees, pits filled with clean soil.
