Development of Surface Water Assessment Procedures

Under the lead of the VSA platform water quality and in collaboration with the Federal Office of the Environment (FOEN), experts from cantonal authorities and consulting companies and other Eawag collaborators, we contribute to the development and improvement of ecological river and lake assessment procedures and their application in surface water management.

Current focus is on the development of assessment procedures for the water quality regarding micropollutants based on chemical analysis and diatoms and a revision of the assessment method for fishes in running waters.

' (147 chars) description => protected'Surface water quality management requires foresighted decision making regard
         ing long-term investments. It should consider multiple objectives (e.g. rela
         ted to different pollutants and costs), integrate multiple sources of pollut
         ion (point and diffuse sources), and external conditions that change over ti
         me (climate, population and land-use changes). Multi-attribute value theory
         can support such decisions, especially the development of an assessment meth

         tants are currently lacking or in development in many countries. Important s
         teps for the development of such an immission oriented and integrated surfac
         e water quality assessment method are discussed in this paper and exemplifie
         d for organic micropollutants. The proposed assessment method goes beyond si

         ssment on a scale from zero to one based on five color-coded water quality c
         lasses and suggestions for the visualization of assessment results. It takes
          into account the toxicity of the micropollutants and their mixture to aquat
         ic organisms by comparing measured concentrations to environmental quality s
         tandards (EQS). The focus of this paper is on aggregation over multiple subs

         s of different aggregation methods are illustrated with didactical examples
         and by an application of the proposed water quality assessment method to pes

         knowledge to help decision makers find and evaluate management alternatives.
          The goal of this process is to achieve the best fulfillment of societal obj

         n be represented and quantified, (ii) how societal preferences can be descri
         bed and elicited, and (iii) how these concepts can best be used to support c
         ommunication with authorities, politicians, and the public in environmental

         address (ii), we emphasize the importance of value functions, in addition to

          "non-standard" value aggregation techniques, the usefulness of flexibility
         of value functions regarding attribute data availability, the elicitation of

' (137 chars) description => protected'Ecological assessment requires the integration of many physical, chemical, a

         uch partial assessments into an overall assessment can considerably affect t
         he assessment outcome – an issue that has been controversially discussed w
         ithin the scientific community for the last decade. Current practice often c
         onsiders only two different aggregation methods, the weighted arithmetic mea
         n (additive aggregation) and the one-out, all-out method (minimum aggregatio
         n). However, both have important drawbacks. Additive aggregation compensates
          a bad status of one quality element by a number of elements featuring good
         status. Minimum aggregation can lead to overly pessimistic assessment result
