AQUALINE – FILE 74

Cette base, longtemps disponible sur ESA-IRS, est de retour sur EINS (base N°74). Produite à l'origine par le "Water Resources Centre, UK" elle a été acquise par "Cambridge Scientific Abstracts".

Aqualine est indexée selon le thesaurus "Water Resources". Quelques termes contrôlés d'Aqualine ont y été ajoutés.

Aqualine couvre les aspects commerciaux, techniques et scientifiques dans le domaine des ressources en eau:

Les articles on ces sujets sont tirés d'une liste de 300 journaux ainsi que des rapports de conférences, des rapports scientifiques, des livres et des thèses.

La base contient environ 238000 enregistrements, à partir de 1960 et est mise à jour mensuellement de 10000 enregistrements par an.

Abstract : Water utilities in the Netherlands aim at controlling the multiplication of (micro-) organisms by distributing biologically stable water through biologically stable materials. Disinfectant residuals are absent or very low. To be able to assess invertebrate abundance, methods for sampling and quantifying these animals from distribution mains were optimised and evaluated. The presented method for collecting invertebrates consists of unidirectionally flushing a mains section with a flow rate of 1 m s super(-1) and filtering the flushed water in two separate flows with 500 mu m and 100 mu m mesh plankton gauze filters. Removal efficiency from mains was evaluated in nine experiments by collecting the invertebrates removed from the mains section by intensive cleaning immediately subsequent to sampling. Of 12 taxa distinguished, all except case-building Chironomidae larvae (2%) and Oligochaeta (30%) were removed well (51-75%). Retention of invertebrates in 100 mu m filters was evaluated by filtering 39 filtrates using 30 mu m filters. Except for flexible and small invertebrates such as Turbellaria (13%), Nematoda (11%) and Copepoda larvae (24%), most taxa were well retained in the 100 mu m filters (53-100%). During sample processing, the method for taking sub-samples with a 10 ml pipette from the suspension of samples with high sediment concentrations was found to perform well in 75% of the samples. During a 2-year national survey in the Netherlands and consecutive investigations, the method appeared to be very suitable to assess the abundance of most invertebrate taxa in drinking water distribution systems and to be practicable for relatively inexperienced sampling and lab technicians. Although the numbers of small, less abundant or sessile taxa were not accurately assessed using the method, these taxa probably should not be the primary focus of monitoring by water utilities, as consumer complaints are not likely to be caused by these invertebrates. The accuracy of quantifying small invertebrates was further improved, however, by filtering the 100 mu m filtrate with a 30 mu m mesh plankton gauze filter.
