| 162. | The varied nature of these status elements, as well as the possible varied services that a water body provides, implies a varied range of techniques and methodologies to estimate and measure both the baseline condition and adverse changes and impairments. They can include chemical analyses, habitat evaluation, toxicity measurements and bio-indices, for instance. Existing work done for purposes of classification and monitoring under the Water Framework Directive should be taken into account when estimating the baseline condition. Where no monitoring data exist for purposes of estimating the baseline condition of the areas of water adversely affected, it may be possible to extrapolate from data available for other similar areas of water, or from general reference sources.
