Update on Domain field from Waitakere Ranges Local Board I have enquired as to how the contaminated sand was spread on the sportsfield and Parks has told me that a sample of the sand was taken before the size of mesh needed to sieve it was chosen. As the sample did not contain glass, nails or small items, the contractor carried out sieving of the sand prior to the laying and spreading on the field area using a 20mm sieve. Clearly this sieve size was too large, allowing material to fall through onto the field. Asbestos and bacteria concerns The flooring material of the old toilet block at Piha does not contain asbestos. This has been confirmed by sample testing of the flooring material by a registered laboratory. No other material was tested as the visual evidence of the demolition material did not identify any items that required testing for asbestos. Parks will now test the sand/soil to confirm that there is no asbestos in the soil to alleviate any fears about the soil material. The soil samples will also be tested for the presence of E.coli bacteria. Comparison testing will be taken around the Domain to provide a base level. Fencing to prevent access It is proposed to install a low wire and waratah fence with orange tape around the whole work site to restrict public access until the completion of the works and to protect the site to encourage grass growth. Planned works Once these steps have been completed, further work will be carried out on the field, according to the original planned works. A drag matt will be run over the surface to assist in levelling and to raise any subsoil particles to the surface. Manual walkovers will then be undertaken to remove any visual unsuitable items from the field.
