أَوْ جَارِيًا وَظَهَرَ فِيهِ أَثَرُهَا، وَالْأَثَرُ: طَعْمٌ أَوْ لَوْنٌ أَوْ رِيحٌ

• Flowing water: It is ruled impure when the effect of impurity becomes apparent in its taste, color, or smell.
• Large stagnant water: The commentary applies the same effect-based rule to a sufficiently large body of stagnant water. For a square pool, 10 by 10 cubits is the cited surface measure, together with sufficient depth so that its bottom is not exposed by normal scooping.
• Thus, merely knowing that impurity entered a large or flowing body of water is not enough by itself; one of the three effects must appear.
