    Abstract This report summarises the results of the region’s groundwater quantity
    and quality monitoring network for 1999.

    It is intended as an overview document and supplements the hydrological
    database and reports containing more extensive analysis.

    Groundwater in the Wellington Region can generally be described as
    being in a healthy condition with levels and quality data within expected
    natural ranges.

    Notable results include:
    - Elevated nitrate concentrations continue to be a feature of groundwater
    samples taken from under the Hautere Plain on the Kapiti Coast.
    - For the last two years the water pressure in the Waiwhetu Artesian
    Aquifer under the Lower Hutt Valley has been above average and often
    close to maximum recorded values.
    - Water levels in the Wairarapa generally continue to be below average
    due to lower winter recharge.
