LWP contributes to national water quality study

LWP contributed to a comprehensive assessment of New Zealand’s water quality in relation to regulatory minimum acceptable states that was funded by the Our Land and Water National Science Challenge. The research produced new information describing where ‘bottom lines’ for four contaminants (nitrogen,  phosphorus, E. coli and sediment) are exceeded across Aotearoa. Bottom lines are regulatory minimum acceptable objectives that are defined by the National Policy Statement for Freshwater Management (NPS-FM). The study describes where the bottom lines are being exceeded and the scale of the challenge associated with achieving these objectives.
