Wellington Catchpit Sediment Investigation 2011: Sediment Chemistry & Particle Size Data

This report briefly describes methodology and presents results for the analyses of contaminants and particle size distributions for catchpit sediment samples. TPH, TOC and heavy metal results were produced by Hill Laboratories. PAH and chemical marker compound results were produced by NIWA.

Purpose
The Greater Wellington Regional Council engaged NIWA to prepare and process catchpit sediment samples collected from Wellington City in 2011 and analyse them for total organic carbon (TOC), total petroleum hydrocarbons (TPH), heavy metal contaminants, polycyclic aromatic hydrocarbons (PAHs) including selected PAH chemical marker compounds and particle size distributions (0-300 µm).
