Results reported for total organic carbon (TOC), total petroleum hydrocarbons (TPH), organochlorine pesticides, Polycyclic aromatic hydrocarbons (PAH), PAH chemical markers, heavy metals and sediment particle size distributions. TPH, TOC and heavy metal results were produced by Hill Laboratories. Organochlorine pesticides, PAH and PAH chemical marker compound results were produced by NIWA. The Greater Wellington Regional Council engaged NIWA to prepare and process marine sediments collected from Wellington Harbour in late 2011, part of long-term monitoring programme for comparison with ANZECC sediment quality guidelines. This included the analyses of samples for sediment contaminants and particle size distributions.
