1. Presentation of practical lessons on environmental sanitation for 4th year 7 - semester

2. 2- ТHEME: Method of determining the boundaries of sanitary protection zone (SPZ) surface water sources. Calculation methods of delimitation. Method of determining the boundaries of sanitary protection zone (SPZ) of underground water sources. Calculated methods of determining the boundaries of the SOA. Methodology sanitary, sanitary topographical, sanitary bacteriology of water sources and water supply.

3. T HE PURPOSE OF THE ACTIVITY  - Learn the basic legal documents regulating the activity of the doctor in the communal hygiene in the implementation of the choice of water sources and the organization of the SOA. - To teach students to use the legislative framework in its selection of water sources and the organization of the SOA. - To teach students to competently carry out sanitary-hygienic assessment of the organization SOA.

4. T HE STUDENT SHOULD KNOW Features valuation of open water sources; Hygienic requirements for the SOA when choosing water source for water supply; Methods of sanitary inspection

5. T HE STUDENT SHOULD BE ABLE TO : SBV organization around a water source; Evaluation of the Legislative Council; Give an opinion on the suitability of the water source for the water supply.

6. T EACHING QUESTIONS The event was held in the territory of the SOA? On what hydro geological index characterized by the formation of water? The dimensions of the boundaries of the SOA. Based on the legislature's public documents organized SOA?

7. CONTITUTION What indicators to look for when sanitation, sanitary and sanitary- epidemiological topographical survey of treatment facilities What indicators determined by technical sanitary surveys water source? What documents issued under sanitary inspection.

8. C ONTENTS CLASSES normative documents border around the water source SOA Provisions on the design and operation of the Legislative Council; GOST "drinking water"; Snip "Water Supply"; 1- border SBV for open water sources: Against over 200 m; The flow and counter position of the parties 100 m

9.  SOA is organized in all water pipes, regardless of their affiliation, supplying water both from surface and from underground sources, including artificial recharge is used for domestic and drinking needs.

10. SOA is organized as a part of 3 zones: 1) -poyas strict regime includes the territory intakes locations, the location of all areas of water supply facilities and water conveyance channel; 2) and 3-zone restrictions include areas designated for protection from pollution of water sources.

11. SBV organization should precede the development and project, which includes a) the delimitation of the area and its constituent zones b) development of action plans to improve the health of SOA by eliminating existing and prevent possible contamination of water supplies and worsening quality of water.

12. Designing the SOA implementation should begin with: sanitary, microbiological sanitary-chemical, hydrogeological investigations in accordance with the program set out in the proposal GOST 951-2000g. "Rules for the selection and evaluation of the quality sources of centralized drinking water supply."

13. 1st zone SOA groundwater and surface water sources and water supply facilities installed in order to eliminate the possible accidental or intentional contamination of water at the source, at the location of water intake and water supply facilities. 2nd and 3rd belt SBV are aimed at preventing adverse effects on the quality and quantity of water used or intended for use underground and surface sources centralized drinking water supply through the implementation of a set of measures, based on local sanitation, hydro or hydrological features of sources water and nature of possible contamination.

15. QUESTIONS FOR CONTROL 1. The role of water factor in the spread of infectious diseases. 2. The chemical composition of the drinking water in the development of infectious disease etiology. 3. The procedure for monitoring the quality of domestic water on a water pipe from open reservoirs. 4. What are the requirements to the quality of the water source used for domestic drinking water supply. 5. What are the zones is SOA

16. CONTITATION 6. The role of the individual elements of the aqueduct in the spread of infection of water (source of water supply, water- supply and sewage treatment plants, water supply). 7. Determination of flow rate of source water. 8. The main methods for improving water quality. 9. Special methods for improving water quality. 10. Laboratory quality control of drinking water with artesian water supply systems.
