Porirua Harbour Subtidal Survey 2010: Sediment Chemistry and Particle Size Analytical Results and QA/QC

The Greater Wellington Regional Council (GWRC) engaged NIWA to prepare and process estuarine sediment samples collected from Porirua Harbour in late 2010 and manage the analyses of both organic and metal contaminants for comparison with ANZECC sediment quality guidelines. Metal contaminants were analysed by Hill Laboratories and reported elsewhere. NIWA provided analytical data for organochlorine pesticides (OCs), polycyclic aromatic hydrocarbons (PAHs) and particle size distributions (0-300 μm). This report describes methodology and presents results [including quality assurance (QA) data] for the analyses of OCs, PAHs and particle size distributions for estuarine sediment samples collected from Porirua Harbour in 2010.
