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.

Bathing Water Quality

Objective: Lake Van is one of the most important recreation areas of the region. Investigation of microbiological pollution of Lake Van is very important for public health. The aim of this study is to assess the microbiological pollution and determine water quality of the lakes Van and Erçek situated within Van Province, which are used for swimming and recreation to protect both human and environmental health. For this purpose, the presence of fecal coliform, total coliform and enterococci were investigated in samples taken from 29 different points of the lakes. Method: Between June and September 2015, 232 water samples were taken from predefined 29 points, every two weeks, and sent to the Public Health Laboratory of Van Province in 300-500 mL sterile plastic bottles in accordance with Bathing Water Quality Regulation (76/160 / EU: add-on clause 5. Membrane filtration method was used to analyze the samples for coliform bacilli and enterococci. Mandatory values according to bathing water quality regulation were taken as 2000 cfu/100 ml,10000 cfu/100 ml and 1000 cfu/100 ml for fecal coliform, total coliform and enterococcus, respectively. Results: In 196 (84%) of 232 water samples collected, no bacterial contamination was found, while 36 (16%) samples were found contaminated with fecal coliform, total coliform and Enterococcus species. At least one or more specimens of poor quality water were detected in 17 of 29 sampled beaches. Conclusion: It was envisaged to take precautions by restricting the use of the places where microbiological pollution was detected. In addition, regular analyzes are important for public health.

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.
