Water quality scientist: Job description

A water quality scientist is responsible for safeguarding all aspects of water quality through scientific analysis and the setting of targets and standards in response to specific legislation. They compare test results with these standards, investigate shortfalls and take action to remedy problems. Depending on the employer, they may also be involved in providing solutions to water quality problems and water quality regulation.

They usually specialise in one of three areas:

• drinking water;
• surface water (rivers, lakes, estuaries);
• groundwater.

More senior roles may involve significant liaison with businesses, the public and other water industry professionals.

Typical work activities

Tasks differ according to the specialist area, particularly with regard to the degree of contact with the public, businesses and regulatory authorities, but all roles are likely to involve some or all of the following:

• taking water samples (although routine sampling may be carried out by technicians);
• carrying out laboratory testing of samples for chemical or microbiological parameters and, in the case of drinking water, assessment of the quality of taste and clarity;
• analysing statistical data on water quality samples;
• visiting sites of concern, for example, potential sources of pollution or contamination, and sources of complaints about drinking water quality;
• liaising with customers and representatives from regulatory authorities;
• investigating reasons for lapses in water quality and suggesting changes or solutions to these problems;
• providing advice on avoiding problems, for example, to businesses discharging effluent;
• negotiating charges for effluent discharges;
• contributing to projects concerning water quality improvement;
• checking customers' premises and the construction of drains;
• investigating pollution incidents from a scientific and legal viewpoint;
• arranging for emergency action in response to incidents;
• conducting research related to water quality and setting up field surveys;
• sharing information with water quality professionals from other agencies.

Work activities may vary according to the current issues of concern; an ongoing and serious problem with water quality may cause other activities to be suspended or minimised until it has been dealt with.

Water quality scientists who work in the field may perform a lot of routine sampling. However, they also have to respond to emergencies when pollution-causing incidents occur.
