Abstract
Vattenfall is assessing routines for the future handling of alkaline coal ash deposits in order to minimize environmental seepage of at least heavy metals. The Swedish Environmental Research Group (MFG) has been given responsibility to produce a background document as a basis for making decisions regarding remedial measures. The present report should be seen only as a step forward in this work. It can be concluded from an examination of current Swedish environmental criteria for metals in inland and marine waters, that these need to be thoroughly reworked. Their use leads at present in many cases to unrealistic incorrect judgements regarding the status of a water body. An important problem is the difficulty in defining reliable and undisputable baseline levels upon which criteria and targets can be based. Agreements surrounding environmental targets should be expressed first qualitatively in terms of the environmental status level or condition that is being aimed for. Following this, different loading or deposit levels can be defined in order to achieve the overall targets agreed to. The basis for our environmental targets should be the ecosystem(s) that we find today as most healthy, diverse and balanced, made up of indigenous species; it should not be based

In addition, the report discusses the meaning and interpretation of the terms `acceptable impacts` `influences` vs `effects`, etc. Numerous examples are described where attention must be given to ambient conditions and to the presence of other metals when defining criteria. Finally, a number of principles are suggested in order to help formulate future water quality criteria for metals. (83 refs., 25 figs., 29 tabs.).}
