The thesis is concerned on the topic "Instruments of environmental protection in the Czech Republic". The environmental law knows some categories of instruments. Mostly they are divided according to the influence to the subjects, respectively if they have direct influence to subjects or not. First category of direct instruments is called conceptual instruments and includes group of plans, programs and other documents concerned on scheming in area of environmental protection. Second group of direct instruments is called administrative instruments. These instruments contain commands, prohibitions, permits and approvals. They also contain standards categorization and ecologically-legal liability. Third group of direct instruments is called voluntary instruments. These instruments contain voluntary agreements, environmental managements systems and eco-labeling. Last group of instrument described in this thesis are institutional instruments. They are concerned on system of institutions which have some competences in environmental protection. They are divided according to area of their competences or according to the kind of competences they have. Indirect instruments are represented mostly by the economical instruments. These instruments are divided according to the form of stimulation of subjects'...

This diploma thesis deals with the legal regime of protected areas and protective zones used to protect water. The diploma thesis is composed of four chapters. Chapter one defines basic terms, a protected area and protective zone, in general. This chapter also contains a comparison of both institutes and their application in environmental protection. The second chapter deals with the sources of relevant legislation protected areas and protective zones to protect water. Chapters three and four are central of the thesis as they contain an interpretation of legislation of each types of protected areas and protective zones to protect water. For individual institutes is analyzed their concept, function, form and method of their determination and especially their special legal regime based namely on bans and restrictions regarding certain activities in the given area. Attention is also paid to various limitations of property rights to real estate in the protected areas and protective zones and to possible compensations for such limitations.

The requirements to protect public water systems from intentional contamination have expanded in the years following September 11, 2001. The areal extent and non-linear nature of water demand and movement in the distribution system makes efficient location of sampling points difficult. This difficulty is compounded by the fact that contamination conceptually can occur at any point and at any time within the distribution system. Small to mid-sized water systems are especially at a disadvantage in addressing this issue due to limited resources available to them. This paper proposes a heuristic methodology to identify strategic locations within the system that can be established as critical detection points for such occurrences. The process uses off-the-shelf software and is structured to be accessible to small and mid-sized water system managers. This methodology is different from others proposed in the literature in that it uses computer simulations to create a database of water system response to contamination at every node in the system. A process is developed to mine this database systematically after considering concentration thresholds and "time since injection" parameters. Finally, using pivot tables and graphs, a network of monitoring locations is identified to provide efficient coverage of the system under the conditions imposed.

During installation and operation of a geothermal heat pump system leakage of an antifreezing agent can appear in a borehole and leak out in surrounding groundwater. To guarantee high quality drinking water for generations to come Sweden has dedicated some areas as water protection areas. The local authority gives permits for the installation of heat pump systems within water protection areas. Before giving a permit the local authority makes an evaluation of the risks involved in installation and operation of the system within the area. By keeping a certain distance between the protected object in the area and the heat pump system the risk of polluting the protected object with an anti-freezing agent can be reduced. This thesis makes a comparison between three different methods of calculating an appropriate distance between the protected object and the heat pump system. These methods include different numbers of parameters to calculate the appropriate distance. The results are evaluated with regard to the parameters used. The methods used are a simplified version of an empirical point-count system made by LeGrand, an analytical solution from Baetsle and a numerical solution with Visual MODFLOW 4.0. / Miljöbalken med bakomliggande miljömål skall bidra till att skydda viktiga naturområden för en hållbar utveckling. Ett stort problem för att tillgodose detta behov är dock alla konkurrerande intressen som kan finnas inom ett och samma område. Vattenskyddsområden utfärdas i syfte att ge tillgång till rent vatten för framtida dricksvatten, men konkurrerande intressen påverkar även dessa områden. Beslut om vilka verksamheter som skall vara tillåtna inom ett vattenskyddsområde tas av den kommun inom vilken området finns. Ett ökande oljepris har under senare år lett till ett ökat intresse av att installera bergvärmeanläggningar. Denna kraftiga ökning har gjort att negativa effekter av att installera dessa anläggningar förbisetts och att installatörer med dåliga kunskaper fått en chans att etablera sig på marknaden. Före eventuell installation av en bergvärmeanläggning inom ett vattenskyddsområde är det viktigt att beakta de risker som en bergvärmeanläggning kan medföra för omgivande grundvatten. En noggrann utredning kräver beaktande av alla de riskmoment som installation och drift av en sådan anläggning kan medföra. För omgivande grundvatten är det dock främst läckage av köldbärarvätska, dvs. vatten med tillfört frostskyddsmedel, som kan ha en större inverkan. Det finns idag ingen övergripande lagstiftning över tillåtna köldbärarvätskor, men enligt de hänsynsregler som finns i miljöbalken och rekommendationer av bl.a. Sveriges Geologiska Undersökning skall etanol användas som frostskyddsmedel. Etanol för tekniskt bruk innehåller denatureringsmedel för att motverka konsumtion. Denatureringsmedel samt etanol kan ge smak och lukt till vatten och är därför inte önskvärda att ha i ett vattenskyddsområde. Dessa ämnen tillför även negativa effekter genom att de som substrat för bakterier kan ge en ökad bakteriehalt i marken. Under nedbrytning av dessa ämnen kan även syrefria förhållanden utbildas i jorden vilket kan leda till utfällningar av järn och mangan samt utbildning av svavelväte. Det finns olika riktlinjer för hur risk med att införa en bergvärmeanläggning i ett vattenskyddsområde beaktas i olika kommuner. Ett lämpligt skyddsavstånd mellan en bergvärmeanläggning och ett skyddsobjekt kan dock göra att risken för att förorena ett skyddsobjekt med etanol kan minimeras. Detta arbete har utförts i syfte att jämföra olika metoder för att ta fram ett skyddsavstånd för en första övergripande undersökning av vilken effekt ett läckage av etanol kan ha på ett skyddsobjekt ett visst avstånd från en ansatt bergvärmeanläggning. De metoder som använts är en förenklad form av en empirisk lösning av LeGrand, en analytisk lösning av Baetsle och en numerisk lösning i Visual MODFLOW.

Authoritative, top-down forms of environmental governance are presently giving way to more collaborative approaches in which decision making is an ongoing negotiation between government and non-government actors. There is growing consensus that critical environmental concerns—such as contamination of drinking water—relate as much to political, economic and social issues, as to technical and scientific issues. As the trend toward collaborative environmental governance continues, and as science-based knowledge increasingly shares a role in decision-making processes with more “local”, non-scientific knowledge, questions arise concerning how diverse knowledge contributions are understood and engaged in these governance processes. This research explored the relationships between knowledge and collaborative environmental governance processes. The purpose of the research was to identify (1) types of knowledge that individual actors bring into collaborative governance pertaining to water resource protection, (2) uses of that knowledge, and (3) features of collaborative processes that affect the engagement of actor knowledge. Collaborative water governance in New Brunswick provided the context for the research. Most actors did not see a definitive distinction between “expert”, scientific and “local”, non-scientific knowledge; they considered both to be important contributions. Nonetheless, science-based knowledge, especially natural science, was found to be a predominant knowledge type among actors involved in collaborative water governance. Science-based, expert knowledge was more readily used than local knowledge types in the various stages of collaborative governance. Leadership and the definition of actor roles were considered paramount for engaging a wide range of knowledge types in collaborative governance processes.

Source Water Protection (SWP) is recognized as the first barrier in the multi-barrier approach to reduce the risk of drinking water contamination. In Canada, provincial water agencies and municipalities lead most of the water management responsibility based on provincial regulations. However, SWP planning and implementation is variable across jurisdictions and influenced by different factors related to local capacity. Much of the water resources literature is focused on capacity-building limitations faced by small and rural water system operators. The purpose of this research is to investigate capacity-building limitations faced by metropolitan water system operators. Information from a questionnaire and document review in four selected Canadian metropolitan areas was gathered and analysed in this study. The results of this study show variability of SWP planning uptake as well as variability in approach toward SWP implementation. While large metropolitan areas may appear to possess ready access to financial capital, technical capability, and other forms of capacity to undertake SWP, the results of this research indicate the opposite. Metropolitan areas in Canada remain reliant on advanced water treatment and other engineering solutions to provide safe drinking water as opposed to SWP planning that invests in preventative measures through land use planning mechanisms. The results of this research contribute to the knowledge and understanding of SWP particularly as applied to metropolitan Canada.

The purpose of this study was to investigate whether water protection areas with nearby shooting ranges could be polluted by lead from ammunition or not. The goal was to make a risk assessment of the hazard for human health and the environment. The risk assessment leads to a classification of the shooting ranges. The work of the inventory was done according to the method developed by the Swedish Environmental Protection Agency, called “Methodology for Inventory of Polluted Areas”. The report contains two types of studies: one literature study and one practical study where interviews were conducted along with a visit to one of the shooting ranges. The results show that one shooting range was considered to be of high risk to the environment because of the high activity that accumulated several tons of lead and the shooting range’s nearness to a water treatment plant. The other two shooting ranges were smaller and not too close to a drinking water source. Therefore the risks were moderate. Conclusions drawn from this report is that water protection areas within nearby shooting ranges are exposed to potential pollution from lead, but the risks aren’t immediate. Probably will time play an important role to prevent lead spreading to the ground water. Because of its attributes, lead has low mobility under normal conditions.  The vertical transport in the ground is considered slow and it could take hundreds of years before it reaches ground water.

Engagement is an essential component to community building. Among the factors which contribute to engagement is perception. Of specific interest to landscape architecture are perceptions of landscape and water as they reveal environmental attitudes. Rural Southern Ontario has experienced notable land use pressures for resource extraction and renewable energy. This study explores the relationship between landscape and water perceptions by rural residents and levels of community engagement in a changing rural landscape. Instruments used for this study were a photo-based questionnaire and Visitor Employed Photography. The study found that individuals who are more engaged with the community have a greater ability to interpret landscape in the context of resource extraction and are more critical in their perception of quarry rehabilitation. Findings of this study can assist rural groups by providing insight into social capital and inform landscape planning and design practices when working with rural groups to increase engagement.
