Besides the beneficial use of dredged material, sustainable relocation, which means keeping the sediments in the natural aquatic material circulation, is one goal for handling dredged material in the port of Hamburg. Decreasing contamination the River Elbe and new dredged material guidelines provide a basis for this. With comprehensive investigations, near- and far-field transport and the effects of relocation regarding the water quality and the benthic community were determined thus deveoloping conditions for future operating strategies.

ABSTRAKTujuan penelitian ini adalah untuk menggunakan komunitas makroozoobenthos sebagaiindikator biologi perairan di hulu Sungai Cisadane melalui aplikasi beberapa indeks biologi.Sampling dilakukan di segmen hulu Sungai Cisadane, Desa Pasir Buncir, KecamatanCaringin, Kabupaten Bogor, Jawa Barat pada bulan Juni - Agustus 2006. Indeks biologi yangdigunakan adalah Indeks keanekaragaman, LQI, FBI, Indeks Pantle & Buck, dan SIGNAL 2,ditambah dengan analisis kualitas air. Hasil penelitian menunjukkan bahwa komposisi dankepadatan makrozoobenthos bervariasi antar stasiun dan antar pengamatan. Dari analisismenggunakan lima metode indeks biologi diduga perairan hulu Sungai Cisadane tercemarsangat ringan hingga ringan. Metode FBI nampaknya paling sesuai diterapkan di sungai ini,dan untuk dipakai di Indonesia.Kata kunci: makrozoobenthos, indeks biologi, pencemaran, sungaiABSTRACTThe aime of the research was to use makrozoobenthic community as bioindicator of CisadaneRiver headstream by some biological indices analyses. Sample collections were made inheadstream segment of Cisadane River in Pasir Buncir Village, Bogor Regency, West Jawaon June – August 2006. Some biological indices were applied, i.e. Shannon-Wiener index,LQI, FBI, Indeks Pantle & Buck, and SIGNAL 2; in addition, water quality analysis was alsoperformed. The results showed that the composition and abundance of makrozoobenthiccommunity varied among sampling stations as well as sampling time. The indices showedthat the river segment was very light until light polluted. FBI seemed to be the suitable indexto determine pollution status in the river, and for applying in Indonesia.Keywords: makrozoobenthos, biological indices, pollution, stream

In this study the water quality of Teluk Lake, Jambi Province by biological indices using macroobenthic during December 2017 to March 2018 were evaluated. Macro obenthic have been the most commonly indicator of running water quality to rapidly detect water quality changes. The methodology consisted on three stages: 1) macro invertebrates sampling and and sorting of the organisms in laboratory, 2) taxonomic identification of organisms and 3) determination and scoring with the Biological Monitoring Working Party -Average Score per Taxon (BMWP-ASPT) index. Result of water quality of Teluk Lake based on the diversity of macroinvertebrates was degraded with BMWP-ASPT index below 4. Based on the BMWP-ASPT score of the macroinvertebrates, both of sampling 1 and 2 were polluted with the category of medium and heavily polluted. In general, the decreasing of water quality of Teluk Lake was due to anthropogenic activities, so that the intolerant macro invertebrates could not survive in polluted waters while the tolerant ones can adapt well to the polluted aquatic environment.

In the years from 1970-1982 52 site studies and monitoring studies have been carried out at major existing and planned power plants. The results from the studies have been used in a planning system for water quality. This planning system, which is water quality related, is described in this paper. An important part of the planning system is the description of size and distribution of excess temperature fields and the related biological conditions. In the biological monitoring, emphasis is placed on the benthic community as more vulnerable to the cooling water discharge. The studies have shown that the excess temperature field within the 1-2° isotherm can produce measurable changes in the benthic community. The temperature effect in the pelagic zone is marginal, however, some effects are seen at sites with a deep water intake of nutrient rich water. Entrainment of fish and Zooplankton can be important in bays and estuaries.

An Irrigation Water Quality Database was developed to help assess the microbiological quality of irrigation water used in fruit and vegetable production in 15 counties in New York (NY) State. Water samples from Tennessee (TN) were also included in the database. Four water quality parameters, quantified generic Escherichia coli, specific conductance, pH, and turbidity, were tested. Ground, reservoir, and running water were sampled over 2 years (2009 and 2010), covering three seasons each year (spring, summer, and fall). TN data are for all three seasons in 2010 only. Overall in NY (254 total samples), ground water had a geometric mean of 1 most probable number (MPN)/100 ml, reservoir water had a geometric mean of 8 MPN/100 ml, and running water had a geometric mean of 52 MPN/100 ml. Overall in TN (63 total samples), ground water had a geometric mean of 1 colony forming unit (CFU)/100 ml, reservoir water had a geometric mean of 5 CFU/100 ml, and running water had a geometric mean of 38 CFU/100 ml. These values are all below the 126 MPN/100 ml United States Environmental Protection Agency's Ambient Water Quality Standards (AWQS) standard for fresh water. The presence of E. coli had very weak but sometimes statistically signficiant correlatation with water specific conductance, pH, and turbidity, depending on the water source but the r-squared effect was not strong enough to make the other measurements a substitute for testing specifically for E. coli in water.
