D2.5

This page displays information extracted automatically from the authoritative "summary list" document published by Taumata Arowai. It sets out in three tables:

  1. the reporting requirements for all suppliers reporting against reporting line D2.5,
  2. the sampling obligations and frequency for any compliance reporting with that rule,
  3. the relevant parameter/determinand with MAVs for the samples taken as drawn directly from the Drinking Water Standards Regulations (2022) (opens in a new tab) or the DWQAR (opens in a new tab) itself.

It also includes an Example Report and a References Table indicating where the summary list information was derived from.
