Master essential calculations for public health and water quality testing.
This practical guide shows how to perform key measurements and interpret results using real‑world examples, with clear steps you can apply in the field or the lab.
From assessing water hardness and soap consumption to estimating ammonia, dissolved oxygen, and oxidisable organic matter, the book translates theory into actionable procedures. It combines standard methods with worked examples to help you obtain accurate, repeatable results.
- Learn to estimate total and temporary water hardness using standard soap solutions and Clark’s scale references.
- Calculate free and albuminoid ammonia, including per‑sample and per‑litre calculations, with method comparisons.
- Measure dissolved oxygen using Thresh’s and Winckler’s methods, with step‑by‑step titration formulas.
- Apply tidy’s process and related procedures to assess oxidisable organic matter in water samples.
Ideal for students and professionals in public health, sanitation, environmental testing, and laboratory work, this edition offers precise techniques that support sound decisions in water quality and hygiene practice.
