Water quality monitoring in estuaries within the Waikato region for Waikato Regional Council.

Number of sites = 4 sites per estuary.
Number of replicates = 1 per site.
Measured variables = Sites are visited within an hour of mid-tide on an outgoing tide. Water measurements: water depth, salinity, DO%, temperature, PH, Enterococci, Faecal coliforms, TP, NNN, NH4, Chlorophyll a, turbidity.
Sampling protocol & QA = Quality control measures are undertaken in accordance with EW’s ISO 9001:2000 standards including procedures for the collection, transport, storage of samples, and methods for data verification and quality assurance to ensure the consistency of data across the programme.
