DOCUMENTATION PAGE WITH ABSTRACT Thai Nguyen University of Agriculture and Forestry Degree Program Bachelor of Environmental Science and Management Student name Nguyen Khanh Huong Student ID DTN1453110065 LEARNING ABOUT MONITORING METHODS OF WATER Thesis Title ENVIRONMENT IN THAI NGUYEN CENTER FOR RESOURCES AND ENVIRONMENT MONITORING Dr Nguyen Thanh Hai - Thai Nguyen University of Agriculture Supervisor (s) and Forestry Abstract: Nowadays, environmental protection in general and protection of water resources in particular is a global issue In Vietnam, water sources in rivers and reservoirs are being seriously impacted by pollution from urban areas, industrial parks, rural residential areas, agricultural activities and other community activities Therefore, prevention of water pollution is a very urgent task In order to assess the quality of water environment, environmental monitoring is a key activity and indispensable in the management and protection of the environment This report covers the functions, tasks and activities of Thai Nguyen Center for Resources and Environment Monitoring, which summarizes theories, experiences and other practical skills that help students access future career-related jobs Thus, students can prepare for themselves well enough to be able to confidently undertake professional work when they graduate i Keywords: Water pollution; Environmental Monitoring; Water environment; Monitoring methods; Number of pages: 45 Date of 25th September, 2018 Submission: Supervisor’s signature ii ACKNOWLEDGEMENT First of all, I would like to send my sincere thanks to teachers of the Advanced Education Program (AEP) as well as teachers of Thai Nguyen University of Agriculture and Forestry, who have taught enthusiastically with extensive knowledge not only for my subjects but also for my soft skills and give me a chance to practice at Thai Nguyen Center for Resources and Environment Monitoring In addition, I would like to thank all supports and help from the leadership of Thai Nguyen Center for Environment and Resources Monitoring, has enabled me to practice at the Center During the internship at the Center, I have learned a lot of practical experience, specialized knowledge and high sense of responsibility in the work In order to get that result, I would like to thank Mr Duong Van Hung - Head of Monitoring Room and all the staffs for their help and created favorable conditions to help me complete my internship I would like to give special thank to Dr Nguyen Thanh Hai, who is always supported and helped me a lot in spending much time for checking my thesis report Finally, I would like to express my deeply gratitude to my family and friends for providing me emotional, unceasing encouragement, physical and financial support I would like to thank all those other persons who helped me in completing this report Because of my lack knowledge, the mistake is inevitable, I am very grateful if I receive the comments and options from teachers and others to contribute my report Sincerely yours, Nguyen Khanh Huong iii TABLE OF CONTENTS DOCUMENTATION PAGE WITH ABSTRACT i ACKNOWLEDGEMENT iii TABLE OF CONTENTS

of all humanity The strong socio-economic development, urbanization and industrial development in our country, together with insufficient awareness and lack of human responsibility that has made environment are increasingly seriously degraded This leads to the risk of ecological imbalance, the depletion of natural resources that affect the quality of life and the goal of sustainable development of the country Facing a series of urgent issues, one of the solutions that the State attaches great importance is the promotion of scientific and technological research and the training of experts in the field of environment, which contribute significantly to the protection of the environment and the country, keeping the planet Earth green for generations to come As a final year student in Environmental Science and Management, Thai Nguyen University of Agriculture and Forestry, the internship is one of the necessary and useful subjects So, I proceed to topic “learning about monitoring methods of water environment in Thai Nguyen Center for Resources and Environment Monitoring " to assist each student to better understand about water environment monitoring and their specialization, consolidate the theories were approached at school since then apply that knowledge in practical Simultaneously, give students the studying and working style properly when they graduate to become qualified professionals who meet the practical requirements Figure 3.1 Examples of the various types of field meters available From up to down: a multi-parameter meter YSI 556 and TOA 22A 3.2.2.3 Handing over the results At the end of the field work, the assigned staff must hand over the results to the parties involved The handover works include: - Minutes of sampling and field monitoring 23 - Field monitoring logs (including quick field measurements and records of relevant factors) - Other documents, contracts and papers 3.2.3 The preservation of water samples - Samples should be preserved according to TCVN 6663-3: 2008 (ISO 5667-3), all reagents (preservative chemicals) must be of pure purity or be labeled clearly for any type of sample when going to the field to avoid confusion - The management and preservation of samples is the next stage of the analysis Taking good samples but not good preservation will damage the sample so in the preservation of the sample must ensure the following factors: - Preservation chemicals can be measured, pre-measured and put into small bottles and sealed to avoid mixing in the field - Distilled water: Each field team needs to carry twice-distilled water during field work, twice-distilled water can be used to clean monitoring or sampling equipment when they are contaminated in the field and can be used to test equipment Notes: + Do not use distilled water when source is unknown + Do not use distilled water that has expired, even when the bottle is sealed + Receive samples at the laboratory 24 Table 3.2 General techniques are suitable for preserving surface water, waste water, storm water, ground water and domestic water Type Storage Parameters of Preservation techniques time bottle Acidity or P, G alkalinity Cooling from 2oC to 5oC 24h (Need to analyze the sample in place) level BOD P Cooling from 1oC to 5oC 24h COD P Freezing to -20oC days Fe (II) P, G Acidification of samples by H2SO4 to pH
