Calculation of additional expense and reduced revenue as a result of drinking water protection in the forest A good portion of the drinking water in Switzerland originates from groundwater wells in the forest. Within the framework of the Water Protection Ordinance these forest areas are designated as groundwater protection zones (core zone, S1; inner protection zone, S2; further protection zone, S3) to protect the drinking water supply against contamination. The designation of a forest area as a protection zone is connected to prescriptions and recommendations influencing forest management and causing additional costs for forest enterprises. On behalf of the Federal Office for Environment, an Excel tool has been developed. With this tool, the additional expense and reduced revenue can be calculated quickly and easily. To reflect the requirements in the tool, courses of action were defined, as they occur in forest management (e.g. no chemical wood treatment in the S2 and S3 zone, utilization of non-polluting fuels and lubricants). Subsequently, these courses were converted into mathematical formulae quantifying the additional costs. Three harvesting methods common in forest management were thereby distinguished, a motor-manual harvesting method, a fully mechanized harvesting method and a harvesting method for steep slopes. The results calculated with the drinking water protection tool can form an essential basis for the discussion on compensation payment for water services from forest management and provide a better communication between forest managers and water suppliers. However, the results of the tool are to be regarded rather as guidelines and should not be taken as absolutely.

<p>Aim of the study was to delineate an appropriate wide-ranging drinking water protection zone for the tapped main Walchhof spring, which is part of the public water supply of the small city of Radstadt in the region of Salzburg, Austria. The immediate hydrographic catchment area of the spring was geological mapped, various electric conductivity measurements at the river Taurach and its tributaries were carried out to detect potential high mineralised (SO<sub>4</sub>) karst water influx and fluorescence tracer tests were performed on the adjacent hydrographic catchment area above the tapped main spring. The Walchhof springs discharge approximate 500 L/s in a complex central-alpine setting within a tectonic window structure built of the Radstadt nappe with permeable carbonate rocks overthrusted by the Schladming-Seckau nappe with mostly non-permeable phyllite rocks. To identify the mean altitude of the catchment area and the Mean Residence Time (MRT) of the spring waters a combination of isotopes <sup>2</sup>H/<sup>18</sup>O, <sup>3</sup>H/<sup>3</sup>He, <sup>13</sup>C/<sup>14</sup>C and tracer gases (CFC, SF<sub>6</sub>) was analysed. The <sup>2</sup>H/<sup>18</sup>O-isotopes were analysed on weekly samples during 2019. <sup>3</sup>H/<sup>3</sup>He, <sup>13</sup>C/<sup>14</sup>C and (CFC, SF<sub>6</sub>) were sampled twice in April and October 2019.  The results indicate a wide-ranging hydrogeological catchment area (max. 90km<sup>2</sup>) at a mean altitude of 2000 ± 200 m and a mixture of old (10-20 yrs) and very old (several thousand years) waters. However, heavy rainfall and snow melt events can add (< 10%) very young water (MRT: days-weeks) to the tapped main Walchhof spring. The combination of these methods allows to reduce the wide-ranging drinking water protection zone mainly to the immediate hydrographic catchment area.</p>

The City

The possible consequences of drying up of the most water - bearing tributary of the Chernaya river in the area of the villages of Ternovka and Chernorechya-the Ai-Todorka river due to construction in the valley are considered. One of the main consequences is the depletion of fresh water reserves in the valley of the riverbeds, of which one has already been completely lost, and the second has been significantly changed. As a result, about 3,000 people may lose access to drinking water. The solution to this problem is complicated by the violation of the river's water protection regime - the Ai-Todorka river protection zone (100 meters) is located on a private territory, which does not correspond to the Federal law on the borders of the coastal water protection zone. This issue is currently under consideration by the Prosecutor's office and the Main Department of natural resources and ecology of the city of Sevastopol (Sevprirodnadzor).

Increased competition between producers has now become one of the critical features of the country’s economy. Within the framework of the Water Strategy of the Russian Federation, technological issues play a significant role both in the protection of water resources and in compliance with the safety requirements and favourable quality of the water used. For more than 20 years worldwide, there has been a transition from a hazard-oriented to a risk-oriented approach in the organization of nature and water protection activities. The use of a risk-based approach determines the mandatory monitoring of all pollutants and calculation methods for assessing various types of toxicity of a substance, their hazardous concentrations based on knowledge of the structure and information about the hazard of substances from international databases and registers. Based on the analysis of the main provisions of the Water Strategy of the Russian Federation until 2020 in conjunction with the conditions of water use affecting the health of the population, the priority problems of technological development in the water protection sector and their medical and preventive support were identified. Measures have been outlined to ensure the compliance of the technology for the protection of water bodies, sources of household and drinking water supply to the population and industrial development for monitoring the effectiveness and efficiency of hygienic regulation, sanitary and epidemiological examination of project documentation and a risk-oriented approach to ensuring the activities of business entities on the territory of sanitary protection zones of drinking water sources: water supply, wastewater treatment from point and diffuse sources of pollution.

The water protection zone of the Tsimlyansk reservoir was chosen as the object of research. The subject of the study was the assessment of the intensity of manifestation of dangerous coastal processes of the reservoir: abrasion-latency, erosion activity. A method for monitoring erosion processes in water protection zones of water bodies using a software and hardware complex based on unmanned aerial vehicles and GIS technologies has been developed and tested. The optimal type of digital elevation models has been determined for assessing the density of the erosion net-work, determining the types of banks and the intensity of manifestation of abrasion and landslide processes, measuring the morphometric characteristics of erosional landforms. The types of erosional landforms were determined and the zoning of the territory of the water protection zone of the Tsimlyansk reservoir was carried out according to the density of the erosional dissection of the relief. Studies have shown that the predominant erosional forms of the relief of the water protection zone of the Tsimlyansk reservoir are ravines and gullies. The maximum average value of the density of the erosional network of the relief within the boundaries of the administrative districts of the reservoir coast falls on the Surovikinsky district. In the Kalachevsky district, the maximum value of the density of the erosion network is noted within the water protection zone of the Tsimlyansk reservoir.
