# Will hydrologic technicians be replaced by AI? Updated October 2026 Hydrologic technicians score 52 out of 100 for AI exposure. AI helps with 62% of their task time, and they stay in charge. AI can do another 13%. 25% needs a person. - **13%** AI can do it - **62%** AI helps - **25%** Needs a person High exposure Higher than 79% of the 923 jobs we scored. ## Task by task We graded 16 tasks, most exposed first. AI can do 2 of them, helps with 10 and leaves 4 to people. | Task | AI exposure | | --- | --- | | Perform quality control checks on data to be used by hydrologists. Automated checks flag errors in hydrologic datasets; person reviews flags. | 70% AI can do it | | Locate and deliver information or data as requested by customers, such as contractors, government entities, and members of the public. Looking up and sending data is routine digital work. | 65% AI can do it | | Write materials for research publications, such as maps, tables, and reports, to disseminate findings. AI drafts text and tables; maps need review. | 65% AI helps | | Analyze ecological data about the impact of pollution, erosion, floods, and other environmental problems on bodies of water. AI speeds analysis of water quality and ecological datasets. | 55% AI helps | | Develop computer models for hydrologic predictions. AI coding assistants speed model writing; hydrologist validates results. | 55% AI helps | ## How hydrologic technicians compare All jobs (923) Life, physical and social science (60) The dark line is **hydrologic technicians, at 52**. Each dot is a score, and darker dots mean more jobs share it. The short marks are the averages, 37 for all jobs and 47 for life, physical and social science. ## Pay and outlook in the US Median pay $64,790 a year, May 2025 People employed 2,840 in the US, May 2025 Projected change in jobs \-1.3% from 2024 to 2034 ## Skills to build - Calibrate and maintain stream flow gauges in the field - Collect water samples with chain of custody forms for labs - Review automated QC flags in Microsoft Excel and Access - Map monitoring sites and check AI drafts in ArcGIS software - Write field reports in Microsoft Word and PowerPoint ## Safer roles nearby 5 related jobs with lower scores. - [Hydrologists48 out of 100](https://www.aigentcy.com/ai-exposure/hydrologists/) - [Wastewater engineers48 out of 100](https://www.aigentcy.com/ai-exposure/wastewater-engineers/) - [Geological technicians43 out of 100](https://www.aigentcy.com/ai-exposure/geological-technicians/) - [Water resource specialists44 out of 100](https://www.aigentcy.com/ai-exposure/water-resource-specialists/) - [Conservation scientists43 out of 100](https://www.aigentcy.com/ai-exposure/conservation-scientists/) ## Questions about hydrologic technicians and AI Will AI replace hydrologic technicians? Partly. About 4 in 10 working hours go to tasks AI can already do, mostly quality control checks on hydrologic data and locating and delivering data for customers. Field gauge readings, water sampling and equipment repair stay with technicians because they need a person at the water site. Which tasks is AI taking over for hydrologic technicians? Quality control checks on hydrologic data (exposure 70) and locating and delivering data to customers (exposure 65) are the first to shift. Automated checks flag errors in datasets, and the technician reviews the flags, so routine checking shrinks. AI also drafts tables and report text, which cuts time on writing up results. Which hydrologic technician tasks stay human? Preparing, installing, maintaining and repairing equipment (exposure 8) and collecting water and soil samples (exposure 10) stay with people. A stream gauge repair needs physical skill and tools, and sampling needs someone standing at the site. Measuring water levels and flow (exposure 10) also needs a person physically present at the gauges. How can hydrologic technicians stay valuable as AI changes the work? Keep field skills sharp on gauges, recorders and samplers, since that work stays with people. Learn ArcGIS to map sites, and check any AI-drafted map before it goes out. Use Excel and Access to review automated QC flags, and keep clean chain of custody records for every lab shipment. ## Related jobs - [Environmental scientists51 out of 100](https://www.aigentcy.com/ai-exposure/environmental-scientists/) - [Surveying technicians49 out of 100](https://www.aigentcy.com/ai-exposure/surveying-technicians/) - [Environmental technicians44 out of 100](https://www.aigentcy.com/ai-exposure/environmental-technicians/) - [Environmental engineering technicians47 out of 100](https://www.aigentcy.com/ai-exposure/environmental-engineering-technicians/) ## Next steps for hydrologic technicians - ### Check your job Your job title is a rough guide.
