There are **standards** for water hardness; using EDTA for complexometric titration in accordance with these standards will suffice. Iron in water can be detected using the o-phenanthroline colorimetric method or the sulfosalicylic acid colorimetric method. As the moderator above mentioned, these are the basic analytical indicators used in water quality testing; there are **standard analysis methods available for reference, so it’s sufficient to consult professional materials.
