Hydrologic Technicians

Every task in this role, whether it passes the census's structural hand-over screen, which models pass it, and why. It is a screen, not a claim about what AI can do: a task can pass and still be beyond the systems of the day. The stricter and looser rules re-vote every task, and small differences between roles are noise.

Passes the screen · 2 of 16 tasks

  • Locate and deliver information or data as requested by customers, such as contractors, government entities, and members of the public.

    quick to check, an existing check settles it, and a mistake is cheap · 6.3% of the role's time · $10.1M · passed by Claude Sonnet, GPT-6 Sol · the models disagreed

  • Perform quality control checks on data to be used by hydrologists.

    quick to check, an existing check settles it, and a mistake is cheap · 6.3% of the role's time · $10.1M · passed by Claude Sonnet, Gemini 3.1 Pro · the models disagreed

Does not pass

  • Analyze ecological data about the impact of pollution, erosion, floods, and other environmental problems on bodies of water.

    reason given most often: nobody can tell quickly whether it worked, and no existing check settles it · 6.3% of the role's time · $10.1M

  • Answer technical questions from hydrologists, policymakers, or other customers developing water conservation plans.

    reason given most often: no existing check settles it · 6.3% of the role's time · $10.1M · waiting on a check

  • Apply research findings to minimize the environmental impacts of pollution, waterborne diseases, erosion, or sedimentation.

    reason given most often: nobody can tell quickly whether it worked, and no existing check settles it, and a failure is too expensive · 6.3% of the role's time · $10.1M

  • Assist in designing programs to ensure the proper sealing of abandoned wells.

    physical work, outside the screen · 6.3% of the role's time · $10.1M

  • Collect water and soil samples to test for physical, chemical, or biological properties, such as pH, oxygen level, temperature, and pollution.

    physical work, outside the screen · 6.3% of the role's time · $10.1M

  • Develop computer models for hydrologic predictions.

    reason given most often: nobody can tell quickly whether it worked, and a failure is too expensive · 6.3% of the role's time · $10.1M

  • Estimate the costs and benefits of municipal projects, such as hydroelectric power plants, irrigation systems, and wastewater treatment facilities.

    reason given most often: nobody can tell quickly whether it worked, and no existing check settles it, and a failure is too expensive · 6.3% of the role's time · $10.1M

  • Investigate complaints or conflicts related to the alteration of public waters by gathering information, recommending alternatives, or preparing legal documents.

    reason given most often: nobody can tell quickly whether it worked, and no existing check settles it, and a failure is too expensive · 6.3% of the role's time · $10.1M

  • Investigate the properties, origins, or activities of glaciers, ice, snow, or permafrost.

    physical work, outside the screen · 6.3% of the role's time · $10.1M

  • Measure the properties of bodies of water, such as water levels, volume, and flow.

    physical work, outside the screen · 6.3% of the role's time · $10.1M

  • Prepare, install, maintain, or repair equipment used for hydrologic study, such as water level recorders, stream flow gauges, and water analyzers.

    physical work, outside the screen · 6.3% of the role's time · $10.1M

  • Provide real time data to emergency management and weather service personnel during flood events.

    reason given most often: a failure is too expensive · 6.3% of the role's time · $10.1M

  • Write groundwater contamination reports on known, suspected, or potential hazardous waste sites.

    reason given most often: nobody can tell quickly whether it worked, and no existing check settles it, and a failure is too expensive · 6.3% of the role's time · $10.1M

  • Write materials for research publications, such as maps, tables, and reports, to disseminate findings.
