4th Mission Report _KE3_Jan –Feb 2013iv. Over-grazing of cattle in the plains and mountain regions causing desertification and erosion andtherefore producing excess silt in water.v. Uncontrolled channels being made by farmers to divert the natural flows of small streams tocombine together to produce larger flows.vi. Mining for marble, where the washings are discharged into the rivers.vii. One of the largest iron mines in the Caucuses, where a proposal to construct an iron smelting andsteel works is being considered.Though this was useful information, Chapter 3 should identify the locations of these anthropogenicactivities so the water bodies at risk can be identified. Prof. Fada agreed to confer with Rafig Verdiyev,Hydrology Lecture, Baku State University and Matanat Avazova, Deputy Director, Monitoring Centre ofEnvironmental Pollution to ensure this information would be in the report.A review meeting was held with KE2, KE4, KE5, the GIS Expert, Rafig Verdiyev, and Matanat Avazova on23rd March. Some 50 water bodies had been identified. This information needed to be produced in mapform and Rafig and Matanat agreed to assist Prof. Fada to define the exact locations of the water bodiesat risk, together with the water quality data.3. GEORGIA (29TH JANUARY - 10TH FEBRUARY 2013)The Department of Environmental Pollution Monitoring of the National Environmental Agency (NEA) ofthe Ministry of Environment Protection of Georgia is responsible for the ambient surface water qualitymonitoring Georgia, and has a central laboratory in Tbilisi. It also is responsible for the National Black SeaMonitoring Laboratory in Batumi. The KE3 worked with staff in both laboratories and submitted aRegional AQC Workshop at the Conference Centre in Marriot Hotel in Tbilisi.Laboratory TrainingCentral Laboratory of the Department of Environment Pollution Monitoring (NEA). Tbilisi 30th January to5th February 2013A number of meetings were held with management staff to plan the work schedule and to update on theprogress of the training.PresentMarina Arabidze NEA Georgia Head of Environment Pollution Monitoring DepartmentElina Bakradze , Head of Atmospheric Air, Water and Soil Analyses LaboratoryAnna Natriashvili, Senior Microbiologist.Zurab Jincharadze, Project Deputy Team Leader1) Organo Chlorine PesticidesThe Chromatography Department consists of two staff:Maka Khvedeliani, Main Chemist, Chromatographer Water SpecialistNino Vasadze, Main Chemist, Chromatographer Soil SpecialistThe Department currently analyzed five OCPs using their GLC with a liquid/liquid extraction techniqueusing Hexane/acetone. There were a number of issues noted:Page 10 of 36
4th Mission Report _KE3_Jan –Feb 2013i) The GLC column is DN- 5, 25mX 0.32mmX0.24µ manufactured by DANI (Italian Co.), which isrecommended for EPA method 608/808, however the ISO 6468 method was being used instead. To assistin identifying the peaks it was recommended to obtain this EPA method.ii) The Department had obtained a new calibration standard of 17 components but this had not been usedas the staff are waiting for a special “certan” vial to be delivered in order to store this standard correctly.iii) Initially, the results from the chromatograms and were not clear, but following further investigations ofthe software, the results were clarified. It was recommended that a SOP is produced to clarify theprocedures.iv) The extraction efficiency had been determined for each of the five pesticides, however this couldchange depending on the water sample characteristics, therefore it was recommended that an internalcalibration standard is used.v) The current sample bottles were HDPP plastic bottles, however, according to the method, these werenot acceptable. It was recommended that these be replaced by 2l amber glass bottles with ground glassstoppers or caps with Teflon inserts.vi) The GLC was not being used at the time, as the high purity nitrogen had been depleted and theDepartment was waiting for new cylinders to be delivered. The Department tried to use another source ofnitrogen, but this was not pure enough. It was recommended to keep a reserve cylinder in stock, and alsoinstall carbon filters inline from the gas cylinder to the GLC to prevent gross contamination.The current staff were relatively new on GLC analyses (6 months) and the training and interfacing of theequipment was undertaken by Vakhtan g Ugrekhelidze, GLC expert (Georgian Isotopic Institute). It wasrecommended that he should be further engaged to assist in the above recommendations.2) Analytical Quality ControlThe Laboratory participates in a number of external quality control schemes, e.g. Accreditation Instituteof Slovakia (SNAS) scheme and had been ranked highly in them which is a good quality control indicator.In addition the laboratory analyses 7 parameters (F, CL, NO2, Br, NO3, PO4, SO4), which includeinternal AQCs to produce Shewhart charts, using independent software. However, internal AQCs were stillrequired for about thirty other parameters. Elina Bakradze was previously responsible for quality controlbut had recently been promoted and this work was transferred to Ms. Gulchina Kuchava, who wascurrently learning these techniques. Elina has written all the procedures Quality Manual, SOP, SP, GP, etc.which are necessary for the ISO 17025 and has provided the training for Gulchina Kuchava on qualitymanual and now the laboratory are progressing the implementation of those procedures. Therefore thetraining submitted during this mission should have proved very useful as a support for this.Recently the certified experts from the “ICI project –Capacity Building on the Water Monitoring andManagement in Georgia, 2011-2013 (Georgia Waters) visited the NEA laboratory and have made anauditi on 3 components viz. , Ion Chromatography analyses and Microbiology. They maderecommendations in March 2013, which have now been implemented. They have concluded that all isnow perfect apart from an amendment on purchasing new reagents.)The KE3 presented a local training workshop on quality control 4th February for 7 staff, and the rest of thepertinent staff attended the more comprehensive Regional Training Seminar on 5th February. In addition,the KE3 submitted a separate training on the UK method validation software to Elina Bakradze.Unfortunately the software was unable to function correctly on the laboratory’s computers, though it hadPage 11 of 36
