Professional Ethics and Standards
Professional ethics and standards
This domain tests judgment: whether you protect public health, report data honestly, and stay within your competence. Ethics questions often present a client pressure scenario with no perfect option.
Core principles
- Competence: accept work only when qualified; use current methods and validated data.
- Integrity: never falsify, omit, or “adjust” monitoring results; document deviations.
- Confidentiality: protect client information but do not conceal imminent health or environmental harm.
- Conflicts of interest: disclose financial or personal relationships that could bias judgment.
- Public welfare: when safety and client loyalty conflict, safety prevails.
- Records: maintain traceable field notes, chain of custody, and review signatures.
Worked example
A client asks you to change a reported benzene concentration from 6 ppb to 4 ppb to avoid a regulatory exceedance. The correct response: refuse to alter the value, explain that falsification violates law and professional standards, preserve the original record, and offer a legitimate path - re-sample with proper QA/QC or report the exceedance with a corrective action plan. If the client insists, escalate to your supervisor and document the request.
Traps
Treating client confidentiality as a shield for fraud; signing a report you did not review; using an outdated method because it gives a lower result; and failing to disclose a conflict before the work begins.
