Ranking of ecotoxisity tests for underground water assessment using the Hasse diagram technique

Abstrakt

The present study deals with the novel application of the Hasse diagram technique (HDT) for the specific ranking of ecotoxicity tests capable of assessment of underground water quality. The area studied is a multi-municipal landfill in the northern Poland. The monitoring network of the landfill constitutes of 27 piezometers for underground water monitoring and two observation points at surface water courses. After sampling, chemical analysis of various water parameters was performed (pH, conductivity, temperature, turbidity (TURB), color, taste, smell and atmospheric conditions: temperature, precipitation and cloud cover, heavy metals content, total organic carbon, sum of PAHs, Na, Mg, K, Ca, Mn, Fe, Ni, Alkalinity, general hardness, total suspended matter (SUSP), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), chlorides, fluorides, sulphides, sulphates, ammonium nitrogen, total nitrogen, nitrate and nitrite nitrogen, volatile phenols, ether extracts (ETHER), dry residues (DRY_RES), dissolved compounds). Parallel to the chemical parameters assessment six different ecotoxicity tests were applied. In order to determine the applicability of the various ecotoxicity tests, a ranking of samples from different monitoring levels according to the test used (attributes) is done by using HDT. Further, the sensitivity of the biotests was determined and compared. From the sensitivity analysis of the both monitoring levels was evident that the choice of ecotoxicity tests could be optimized by the use of HDT strategy. Most reliable results could be expected by the application of root growth inhibition of Sorghum saccharatum (PGSS test). In order to clarify the relationship between the chemical parameters measured and each of the ecotoxicity tests a optimized similarity analysis between Hasse diagrams for the ecotoxicity tests for different levels of monitoring and Hasse diagrams obtained by the use of the chemical parameters was performed. Finally, it could be concluded that for reliable monitoring of underground waters passing a dump collector following chemical parameters are of significance: water hardness, dissolved matter, total nitrogen (ammonia and nitrate nitrogen), nickel, chlorides, alkalinity, total organic carbon and ether extract and the proper battery test could include PGSA, PGSS and PRSS.
