Good news! On November 24, 2022, We received a letter from DOAJ that Journal of Groundwater Science and Engineering has been accepted for inclusion in DOAJ ( http://www.doaj.org/ ) . 

DOAJ, along with PubMed SCI Scopus and EI, is one of the world's top five document retrieval systems. It is jointly created and maintained by Lund University Libraries and SPARC (The Scholarly Publishing and Academic Resources Coalition). It was established in May 2003 and has included 14,401 open access journals so far, covering all fields of science, technology, medicine, social sciences and humanities.  

   The DOAJ system includes articles in journals that are rigorously reviewed and high-quality full texts that are synchronized with the journal's issuance. All DOAJ articles can be downloaded for free. It aims to cover all high-quality OA journals as widely as possible as well as to improve the visibility of open access journals, thereby increasing the usage rate and influence of journals. The database is a high-quality OA journal catalog website, which is free, full-text, and high-quality. It has high reference value for academic research.
