Water Science information

What is water science?

Water science is the study of water, including its properties, distribution, movement, and quality in the environment. It encompasses disciplines such as hydrology, hydrogeology, and water resource management. Water scientists analyze water samples, monitor water systems, and develop solutions for water conservation and pollution prevention. Their work is crucial for ensuring safe drinking water, sustainable water use, and protecting aquatic ecosystems.

What are some common challenges faced by water scientists when conducting field research?

Water scientists often encounter challenges such as unpredictable weather conditions, difficult terrain, and limited access to remote sampling sites during field research. Additionally, ensuring the accuracy and reliability of samples can be complex due to contamination risks or equipment malfunctions. Collaboration with local authorities and stakeholders is frequently necessary to gain site access and gather comprehensive data. These challenges require adaptability, strong problem-solving skills, and effective communication to ensure successful research outcomes.

What are the key skills and qualifications needed to thrive as a water scientist, and why are they important?

To thrive as a Water Scientist, you need a strong background in environmental science, hydrology, chemistry, or a related field, typically with at least a bachelor's or master's degree. Familiarity with water quality testing equipment, GIS software, and data analysis tools is often required, along with certifications such as Certified Hydrologist or equivalent. Strong analytical thinking, problem-solving abilities, and effective communication skills help distinguish top performers in this role. These qualifications ensure accurate assessment of water resources, inform policy decisions, and support sustainable water management practices.

What is the difference between Water Science vs Water Quality Technician?

AspectWater ScienceWater Quality Technician
Required CredentialsBachelor's degree in environmental science, hydrology, or related fieldAssociate's or bachelor's degree in environmental science, chemistry, or related field
Work EnvironmentResearch labs, field sites, environmental agenciesWater treatment plants, laboratories, field sampling sites
Employer & Industry UsageEnvironmental consulting, government agencies, research institutionsMunicipal water treatment facilities, environmental testing labs

Water Science involves studying water systems, conducting research, and analyzing water data, often in research or policy roles. Water Quality Technicians focus on testing and monitoring water quality at treatment plants or field sites. While both roles require knowledge of water analysis, Water Science emphasizes research and data interpretation, whereas Water Quality Technicians concentrate on sample collection and lab testing.

What can I do with a water science degree?

A water science degree prepares individuals for careers in environmental consulting, water resource management, research, and regulatory agencies. Graduates often work as hydrologists, water quality specialists, or environmental scientists, utilizing skills in data analysis, field sampling, and environmental regulations.

What does a water scientist do?

A water scientist studies the properties, distribution, and quality of water resources. They analyze water samples, develop models, and assess environmental impacts to support water management and conservation efforts, often using tools like GIS and laboratory equipment. Their work may involve fieldwork, data analysis, and reporting to inform policy and sustainable practices.

Our research team is dedicated to the Surveillance and Control of Pathogens and Antimicrobial Resistance (AMR) in the Environment, predominately focusing on how to monitor and model the risks that waterborne pathogens and other pollutants pose to human health. The research program is led by the Canada Excellence in Research Chair (CERC) in Waterborne Pathogens: Surveillance, Prediction and Mitigation. Our primary areas of research are smart sampling systems, lab-based pathogen and AMR detection, novel low-cost water quality sensor development, source tracking, modelling and risk estimation, and novel green infrastructure-based pathogen treatment systems. We are seeking a highly motivated and experienced Water Microbiologist to join our team.

General outline of duties: This position will play a key role in lab-based pathogen and AMR detection. They will be required to establish, optimize and perform lab-based pathogen and AMR detection on a regular basis using culture-based and molecular methods; they will be responsible for the proper tracking, documentation, storage, and processing of water samples based on establish procedures; they will participate in field research, including the execution of water sampling and sensing campaigns; they will be responsible for data collection, screening and quality control; they will be involved in the general support of research activities for a growing and dynamic interdisciplinary research team.

Our research environment is highly collaborative. Candidates who bring a positive and team-focused attitude, who are self-motivated, and enjoy working within a fast-paced environment, will be most successful in this role.

Duties and Responsibilities

  • Collaborate with the Principal Investigator, students and staff to meet research program milestones. For more information on ongoing projects in the program see microscape.ca.
  • Develop, validate, and execute new or optimized methods, and prepare associated research documentation, including but not limited to lab protocols, field data collection forms, SOPs, and records.
  • Independently perform routine water sampling and analysis following standardized guidelines and procedures, including recording and/or coding data requiring some judgement/interpretation.
  • Communicate technical information accurately and effectively in oral, written, visual and electronic forms. The applicant will be expected to serve as a source of information on standard research techniques, train others in technical procedures or operations, and provide guidance to students on use of equipment or standard research techniques for their research projects.
  • Operate, maintain and troubleshoot problems with basic lab equipment.
  • Supports data management, performs preliminary analysis when appropriate; recognize obvious deviations in research results and flag for senior researchers to address.
  • Support the knowledge translation and transfer of research outcomes to project stakeholders. This may include contributing to project reports, manuscripts, grant proposals and other research presentations.
  • Organize laboratory and stock, maintains inventory, replenishing supplies as required. This includes the preparation of media, buffer, reagents, solutions, cultures and related material according to specifications for routine laboratory use.
