| Abstract: | A project to remove contaminated sediments from and widen and deepen
the Waiwhetu Stream was carried out over the period November 2009 through May 2010. This report summarises the remediation aspects of the project. The Waiwhetu Stream is a relatively small, slow flowing, and tidally- affected stream that rises in the Eastern Hills of the Hutt Valley, then flows south for approximately six kilometres to its confluence with the Hutt River estuary at Port Road. The lower reaches of the Waiwhetu Stream suffer from long standing heavy metal pollution, in particular lead, zinc, chromium and copper, as a result of historical untreated discharges from local industries in the Gracefield and Seaview area. |
