NIKM – distribuce KM/PKM v SO ORP České republiky
Suchánek, Zdeněk ; Řeřicha, Jaroslav
Národní inventarizace kontaminovaných míst (projekt NIKM 2) byla dokončena v prosinci 2021. Představujeme výstup týkající se distribuce inventarizovaných kontaminovaných a potenciálně kontaminovaných míst (KM/PKM)) v 205 správních obvodech obcí s rozšířenou působností (SO ORP). V Hlavním městě Praha, které je krajem i obcí, a tudíž i ORP, má obdobnou působnost jako ORP všech 22 městských částí. Naplněná databáze Systému evidence kontaminovaných míst (SEKM) slouží jako hlavní zdroj pro tzv. územně analytické podklady, tj. pro územní plánování na úrovni ORP. Doposud byly používány neúplné podklady o KM/PKM, takže územní dokumentace nemusela reflektovat reálnou situaci v kontaminaci území. Po dokončení inventarizace mohou být aktualizace územně analytických podkladů v této problematice založeny na relevantních datech.

Effectiveness of the use of clues of contaminated sites obtained by remote sensing for the National Inventory of Contaminated Sites
Suchánek, Zdeněk ; Řeřicha, Jaroslav
The National Inventory of Contaminated Sites (NIKM) project was aimed to fill the database of the Contaminated Sites Register (SEKM) with approximately 9053 updated and validated records with evaluated priority, taking into account the risk from the point of view of life and health of the population and the environment. We expect the number of records to be approximately 10100. Thousands of contaminated and potentially contaminated sites (KM / PKM) entered in the SEKM register are also waste management sites. The article focuses on the possibility of using information from the inventory for waste management. The initial project task implemented in the years 2018–2019 concerned the mapping of KM / PKM clues by remote sensing (RS) methods. The mapping provided a wealth of insights into the territorial distribution of clues. Using remote sensing methods, a significant part (approx. 18%) was obtained from the total number of approx. 10100 evaluated sites registered in SEKM. 48.5% of all records of evaluated localities arising from clues come from the group of types of clues determined using remote sensing methods and related to municipal waste (types of clues c, p, l, r). The use of remote sensing methods, such as the interpretation of orthophotomaps, can be a significant benefit for the performance of public administration in the field of spatial planning and environmental protection. Today, SEKM is a complete public database of the Ministry of the Environment that can be used by the professional and general public. Many of information contained in it can be used for the issue of waste disposal on the surface.

Old municipal waste landfills inventoried in the Contaminated Sites Registration System
Suchánek, Zdeněk ; Řeřicha, Jaroslav
The database of the Contaminated Sites Registration System, filled in at the end of 2021 as part of the National Inventory of Contaminated Sites for the number of 10,134 records of assessed contaminated and potentially contaminated sites, contains, amongst other data, 4,619 sites registered as a “Solid Municipal Waste Landfill” type. This part of the database, together with additional information sources, was analysed in terms of parameters such as landfilling duration, landfill closure date, landfill size (area), location (territorial representativeness), state of knowledge about the landfill, and its risk and time urgency for possible corrective measures. We interpreted the obtained historical and current data on old municipal waste landfills and used them for the preparation of criteria for multi-criteria selection of the main types of old landfills and the selection of specific sites for sampling and technical works, to be done within the subsequent research project. The selection of landfills for sampling will be representative in the case of old municipal waste landfills, which are located in the South Bohemian, South Moravian, Central Bohemian and Vysočina regions. They should have an area of more than 100 m2, be of categories P and A, not having any set corrective measures, with an absence of the financing of remedial measures, be landfilled between 5 to 55 years and their landfilling activities having been terminated in the 1990s.

Status of implementation of the National Inventory of Contaminated Sites project
Suchánek, Zdeněk ; Řeřicha, Jaroslav ; Krhovský, Jan
By mid-April 2021, the inventory of contaminated sites in 52 districts out of the 77 districts of the Czech Republic was completed. 6403 records are already stored in the SEKM, ie 70.7 % of the planned parameter (target number of at least 9053 records). The inventory already covers 68.5 % of the inventory area. The inventory in the regions has already been completed with reports for the Jihočeský, Liberecký, Karlovarský, Královéhradecký and Pardubický regions. Monitoring and control of the “yield” of individual sources (SEKM, indications obtained by remote sensing, new sites) resulted in ongoing methodological guidance of inventory teams (control days, training, consultations, manuals and methodological recommendations). The project management gradually adopted 18 adjustments to the work schedule, ie. without affecting the project completion date. Linear extrapolation of the number of existing approved SEKM records on the entire territory of the Czech Republic makes it possible to assume that the prescribed parameter - 9053 records of contaminated sites with evaluated priority - will be achieved on time. The project will be completed by 31 December 2021.

Methodology of thematic mapping of environmental phenomena by remote sensing methods
Řeřicha, Jaroslav ; Suchánek, Zdeněk ; Krhovský, Jan
The general methodology of conducting thematic mapping works using remote sensing methods is based on the authors' experience with the task of “Supporting Inventory of Contaminated Sites by Remote Sensing Methods” within the National Stake Inventory Inventory Stage 2 (NIKM2) works. Identification and location of possible sites, resp. objects of interest with probable contamination by distance methods (“contaminated site clues”) represent an important part of the methodology of contaminated sites inventory and fill approximately 50% of the input to the database of sites for inventory. A concrete example of the project (case study) “Mapping the distribution of indications of contaminated sites in the Czech Republic” illustrates the applicability of the developed methodology.

Distribution of identified clues of contaminated sites in the Czech Republic
Suchánek, Zdeněk ; Řeřicha, Jaroslav ; Krhovský, Jan
The project of Phase 2 of the National Inventory of Contaminated Sites (NIKM 2) includes the preparation of geographical data. The initial and main task of this part of the project is to acquire the finding database using remote sensing methods. During the first 16 months of the NIKM 2 project, a thematic layer of 14 different types of contaminated site (CS) clues (indicia), respectively of potentially contaminated sites (PCS) clues, was created by interpreting photomaps and other geographical data. The works of 12 CENIA interpreters were carried out in the environment of the geographic information system QGIS. Interpretation of remote sensing data revealed 34,666 clues in the first phase of interpretation. The primary finding database was further revised in order to objectify and standardize its content. The number of valid clues was thus reduced by about half. Thematic classification of the indices enabled a subsequent statistical evaluation, which serves as a basis for the optimization of the field survey, i.e. for the planning of the area inventory taking into account the character of the territory. From the evaluation of the collected data we can also consider the effectiveness of regulations and measures of local authorities and the link to the socio-economic, resp. demographic indicators, etc. The graphical and tabular outputs document the spatial links of the identified contaminated site indications and are the basis for the next phases of providing geographical support for the inventory work of the NIKM 2 project in 2019-2021.Uh
