Studying the water quality is significant to protect and for coastal area-use planning in Banda Aceh City, Aceh Province. This study took seawater samples from 13 stations in the northern waters of Banda Aceh on September 10-11 2019. Surface water samples were taken using Van Dorn bottle, which were then tested on 22 types of parameters to evaluate the water quality in the area. In general, the results of tests on various water parameters indicate that the sea waters in Banda Aceh are in good condition. Attention needs to be paid to nitrates and phosphates, which indicate values that exceed water quality standards, thus possible to trigger algal blooms.Keywords:Water qualityNitrateFisheryABSTRAKKajian kualitas air sangat penting untuk melindungi serta untuk perencanaan pemanfaatan ruang pesisir di Kota Banda Aceh, Provinsi Aceh. Penelitian ini mengambil sampel air laut dari 13 stasiun yang di perairan utara Banda Aceh pada 10 – 11 September 2019. Sampel air permukaan laut diambil menggunakan botol Van Dorn, yang kemudian dilakukan uji terhadap 22 jenis parameter untuk mengevaluasi kualitas air di perairan utara Kota Banda Aceh. Secara umum, hasil pengujian pada berbagai parameter air menunjukkan bahwa air laut di Banda Aceh dalam kondisi baik. Perhatian perlu diberikan pada kadar nitrat dan fosfat, yang menunjukkan nilai yang melebihi baku mutu air, dimana memungkinkan untuk memicu pertumbuhan alga yang berlebihan di kawasan tersebut.Kata kunci:Kualitas perairanNitratPerikanan

Surface Water Samples

Nationwide surveys of 1,4-dioxane and methyl-t-butyl ether (MTBE) levels in raw water used for the drinking water supply were conducted at 91 water treatment plants in Japan in 2001 and 2002, prior to the revision of the drinking water quality standards. 1,4-dioxane was widely and continuously detected in raw water samples and its occurrence was more frequent and its concentrations higher in groundwater than in surface water. However, its maximum concentration in raw water was much lower than its new standard value (50 μg/L), which was determined as a level of 10−5 excessive cancer risk to humans. Trace levels of MTBE were also detected in several surface water samples.

Groundwater Samples

Various samples of groundwater were collected from different areas of Kandarvakottai and Karambakudi of Pudukkottai District, Tamilnadu and analyzed for their physicochemical characteristics. The results of this analysis were compared with the water quality standards of ISI, WHO and CPHEEO. In this analysis the various physicochemical parameters such as pH, electrical conductivity, turbidity, total dissolved solids, Cl-, F-, SO42-, PO43-, NO3-, NO2-, CN-, Nas+, K+, NH3, Mn, Fe, Ca & Mg hardnessetc., were determined using standard procedures. The quality of groundwater samples were discussed with respect to these parameters and thus an attempt were made to ascertain the quality of groundwater used for drinking and cooking purposes in and around Kandarvakottai and Karambakudi areas.

The Impact

An assessment of the impact of the new microbial water quality standards of the proposed EU Bathing Water Directive on the classification of designated Irish coastal bathing areas is presented. The new standards are applied retrospectively to the microbial water quality results for the bathing seasons of 1999, 2000 and 2001, and the outcome is compared with that recorded under the present Bathing Water Directive. A Microsoft EXCEL application was developed to generate the retrospective bathing area classifications according to the proposed Directive (Excellent, Good, Poor). It was found that the number of Irish coastal bathing areas not attaining ‘Excellent’ classification (as would be required at present for the Blue Flag award) was trebled; the number attaining ‘Good’ classification was increased by about 50%, and the number attracting ‘Poor’ classification (equivalent to ‘Fail’ under the present Directive) was increased nine-fold. Some of the shortcomings of the proposed Directive and suggestions for its revision are discussed.
