About this report

The report provides information on the routine monthly monitoring of water quality at 102 locations across the Waikato region, and includes:

  • year 2017 summary statistics tabulated by parameter and reported together
  • spatial contour plots for four water quality parameters using spatial interpolation of the median of the previous 5 years
  • summary tables identifying the number of samples meeting ‘satisfactory’ and ‘excellent’ water quality guidelines and standards.

This report is the 22nd since the implementation of the regional rivers monitoring programme (RERIMP) in 1993[1] and follows the format of the previous data report (Tulagi, 2017).
