This study explored the spatial distribution and co-occurrence of microplastics and the\n                    <jats:italic>intI1<\/jats:italic>\n                    antibiotic-resistance-associated marker in the rural water bodies in Madavarayapuram, Tamil Nadu, India using a GIS-based exploratory framework implementing the SDG 3, SDG 6, and SDG 13. Seventeen drinking, tap, wastewater and river water samples were collected and analyzed by Fourier Transform Infrared; polyolefins were discovered, predominantly polypropylene in drinking water, despite the latter revealing zero turbidity. The polyolefin fractions varied by site, with tap water containing 95.73% relative polyolefin fraction, the wastewater at 86.79%, and the wastewater having substantial turbidity at 14.3 NTU, suggests that there is variation in relative polymer fractions and turbidity of the screened water based on sampling site. Samples were gathered at many sites along the river, although few samples were taken, so spatial patterns are difficult to analyze. However, there was an important difference between water types in turbidity (Kruskal-Wallis,\n                    <jats:italic>p<\/jats:italic>\n                    = 0.043) but not in polymer composition (\n                    <jats:italic>p<\/jats:italic>\n                    = 0.748). The presence of culturable bacterial populations in each of the samples was confirmed by microbial analysis, and Presence of the\n                    <jats:italic>intI1<\/jats:italic>\n                    antibiotic-resistance-associated marker (approximately 280 bp) can be detected qualitatively by PCR. However, detection of the\n                    <jats:italic>intI1<\/jats:italic>\n                    marker by PCR does not guarantee that antibiotic-resistant bacteria are present. The method does not identify antibiotic resistance. The detection of microplastics and the antibiotic resistance gene,\n                    <jats:italic>intI1<\/jats:italic>\n                    , in all environmental water matrices that were tested suggests an associated co-occurrence, however it does not suggest or prove that there is a direct correlation between microplastics and the occurrence of antibiotic resistance transmission. These findings highlight the limitations of conventional monitoring approaches and the need for integrated and thorough rural water supply systems to ensure safety.\n                  <\/jats:p>","DOI":"10.3389\/fmicb.2026.1912851","type":"journal-article","created":{"date-parts":[[2026,9,18]],"date-time":"2026-09-18T05:36:58Z","timestamp":1789709818000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Microplastics and intI1 antibiotic resistance-associated marker in rural water systems: an exploratory GIS-based environmental assessment"],"prefix":"10.3389","volume":"17","author":[{"given":"Sneha","family":"Gautam","sequence":"first","affiliation":[{"name":"Division of Civil Engineering, Karunya Institute of Technology and Sciences, Deemed University, Coimbatore","place":["Tamil Nadu, India"]},{"name":"Department of Climate and Energy Systems Engineering, Ewha Womans University","place":["Seoul, Republic of Korea"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bairi Levi","family":"Rakshith","sequence":"additional","affiliation":[{"name":"Division of Mechanical Engineering, Karunya Institute of Technology and Sciences, Coimbatore","place":["Tamil Nadu, India"]},{"name":"Centre for Research in Material Science and Thermal Management (CRMS and TM), Karunya Institute of Technology and Sciences, Coimbatore","place":["Tamil Nadu, India"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jerlin","family":"Joy","sequence":"additional","affiliation":[{"name":"Division of Biotechnology, Karunya Institute of Technology and Sciences, Coimbatore","place":["Tamil Nadu, India"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anu","family":"Jacob","sequence":"additional","affiliation":[{"name":"Division of Biotechnology, Karunya Institute of Technology and Sciences, Coimbatore","place":["Tamil Nadu, India"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.","family":"Subith","sequence":"additional","affiliation":[{"name":"Division of Biotechnology, Karunya Institute of Technology and Sciences, Coimbatore","place":["Tamil Nadu, India"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ashlin","family":"A","sequence":"additional","affiliation":[{"name":"Division of Civil Engineering, Karunya Institute of Technology and Sciences, Deemed University, Coimbatore","place":["Tamil Nadu, India"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lazarus Godson","family":"Asirvatham","sequence":"additional","affiliation":[{"name":"Division of Mechanical Engineering, Karunya Institute of Technology and Sciences, Coimbatore","place":["Tamil Nadu, India"]},{"name":"Centre for Research in Material Science and Thermal Management (CRMS and TM), Karunya Institute of Technology and Sciences, Coimbatore","place":["Tamil Nadu, India"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dennis","family":"Jose","sequence":"additional","affiliation":[{"name":"Division of Biotechnology, Karunya Institute of Technology and Sciences, Coimbatore","place":["Tamil Nadu, India"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Baehyun","family":"Min","sequence":"additional","affiliation":[{"name":"Department of Climate and Energy Systems Engineering, Ewha Womans University","place":["Seoul, Republic of Korea"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,18]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"100610","DOI":"10.1016\/j.cartre.2026.100610","article-title":"Synthesis of 2-arylbenzothiazoles using a novel MWCNTs@Zeolite@Fe3O4 NPs catalyst in DES.","volume":"23","author":"Abu Shuheil","year":"2026","journal-title":"Carbon Trends"},{"key":"B2","doi-asserted-by":"publisher","first-page":"121508","DOI":"10.1016\/j.watres.2024.121508","article-title":"Fate and behaviour of microplastics (> 25\u03bcm) within the water distribution network, from water treatment works to service reservoirs and customer taps.","volume":"255","author":"Adediran","year":"2024","journal-title":"Water Res"},{"key":"B3","doi-asserted-by":"publisher","first-page":"107614","DOI":"10.1016\/j.jwpe.2025.107614","article-title":"Current microbiological challenges in drinking water.","volume":"72","author":"Afonso","year":"2025","journal-title":"J.
