We have structured this index to help you choose an appropriate periodic monitoring technique and standard. It was formerly part of the M2 guidance document.

Standards may contain various options and approaches.

We have produced method implementation documents (MIDs) for several standards to make sure they are applied consistently.

If a MID has been produced we have included it in the index, next to the relevant standard.

Substances are listed in alphabetical order.
