3. Technical notes: Technical notes should include creative and simple results with academically new and valuable data.
4. Technical information: Technical information should provide new and practical information related to the areas of expertise in environmental engineering.
5. Field reports: Field reports should provide technically valuable data based on field experiences relevant to the investigation reports of realms of expertise in environmental engineering fields as well as on the design and maintenance of environmental facilities.
6. Special features: The Editorial Board selects topics and authors regarding proper assignments in the area of expertise related to environmental engineering and ultimately, requests such manuscripts.
7. Letter to the Editor: These contributions include opinions, questions, and responses to the questions associated with the previous published papers of this journal. However, letters to the Editor are limited to the ones that are published within the past 2 years.

∎ Language and length of manuscripts
1) The cover of all manuscripts (the first page) should include the title, full names of researchers, institutional affiliations of researchers, positions and ORCID (Open Researchers and Contributors ID) in both Korean and English, regardless of the language used in the text.
If the affiliations of the authors are different, authors with different affiliations from the first author should be marked with a superscript numeral designation on the upper right of the researchers’ names. The primary author is the first author and the corresponding authors are marked with a symbol † on the upper right of the names.
2) The manuscript should be assigned in the following sequence:
Cover page, extended abstract in English, extended abstract in Korean (for Korean manuscripts), introduction, methods (or materials and methods), results, discussion (or results and discussion), conclusions, acknowledgements, explanation of abbreviations, references, tables, and figures.
3) Extended abstract in Korean (may be omitted if an English paper is prepared) and English should provide the objectives, methods, results and discussion, and conclusions within one and half pages. However, abstracts in Korean and English may be omitted for special features, technical notes, technical information, and field reports.
4) The body of the article (introduction to conclusion) should be numbered consecutively with Arabic numerals, as shown in the example below. e.g.) 1, 2, 3, ……, 1.1, 1.2, ……, 1.1.1, 1.1.2, ……, (1), (2), (3), ……
5) The utilization of the SI system is recommended; yet, the C.G.S.system can also be used for a widely utilized concentration unit, such as mg/L.
