NIWA scientists are part of a team hoping to answer questions about how climate change might affect disease rates in New Zealand, such as those caused by pathogens like Cryptosporidium and Campylobacter, two major causes of disease in New Zealand.
Freshwater Update 35, July 2010
This month we bring you a full-length edition of FWU, with national river flow and water quality maps and information, and updates on three research projects.
Water temperature and clarity information, April to June 2010.
Heavy metals, released by wear on tyres and brake pads, are washed off roads and can contaminate rivers, streams and harbours. NIWA has recently completed a study to measure how much copper and zinc is discharged in road runoff, and how well different stormwater devices remove these contaminants from runoff.
Our last three-monthly predictions, and what actually happened.
Monthly and seasonal river flow information, and our outlook for the coming three months.
