Storm Contamination Severity
Separate debris-only events from runoff intrusion and true floodwater or sewage exposure so you do not apply a casual cleanup plan to a public-health problem.
- Separate debris-only events from runoff intrusion and true floodwater or sewage exposure so you do not apply a casual cleanup plan to a public-health problem.
- Free Chlorine
- pH
- If you cannot confidently rule out floodwater, sewage, or septic contamination, classify the event in the more severe category until proven otherwise.
- Do not assume the usual residential shock and filter routine is enough when the pool took in significant runoff or muddy water.
- Do not tell yourself this is fixed because the pool looks clearer after chlorine and filtration.
Classify the event as debris-only, runoff, or floodwater before choosing a recovery plan.
- ✕Do not apply a casual debris cleanup plan to runoff or floodwater contamination
- ✕Do not re-open based on appearance alone after sewage or floodwater exposure
Free Chlorine / pH
Classify the event before touching the chemistry
The first decision is what entered the pool and equipment area, not which oxidizer to add.
- If you cannot confidently rule out floodwater, sewage, or septic contamination, classify the event in the more severe category until proven otherwise.
Debris-only events
This is cleanup work plus chemistry verification rather than full decontamination.
Runoff intrusion events
Runoff can carry soil, fertilizers, organics, metals, and unknown contaminants beyond ordinary debris cleanup.
- Do not assume the usual residential shock and filter routine is enough when the pool took in significant runoff or muddy water.
Floodwater or sewage exposure
This is a public-health and site-safety event, not a normal homeowner water-balance problem.
- Do not tell yourself this is fixed because the pool looks clearer after chlorine and filtration.
- Do not re-open based on appearance alone after sewage or floodwater exposure.
Handle equipment and refill water as separate decisions
Storm contamination often affects more than the water in the vessel.
Know the conservative stop conditions
The right escalation point is earlier than most owners think during contamination events.

汚染対応の境界
所有者が安全にできる清掃は、事象が単なるゴミの問題ではなくなった時点で終わります。公衆衛生上の不確実性があるなら、判断は保守的なエスカレーションへ向けるべきです。
- ✓ 事象は保守的に分類し、目に見えるゴミを取り除き、状況を記録し、深刻さを評価する間は人を近づけないでください。
- ✓ 直接の検査と段階的な清掃は、事象が本当にゴミだけか、下水や洪水の証拠がない軽い流入の場合だけに使ってください。
- ✓ 清掃で履歴が消える前に、水源、浸水した機器、汚染された物品の証拠を残してください。
- ★ 下水、浄化槽のあふれ、実際の洪水曝露、または浸水した電気機器の後にプールを復旧します。
- ★ 地域の保健指針、廃棄ルール、規制された施設の要件が適用される場合は、再開基準を決めます。
- ★ 汚染された媒体、多孔質の付属品、災害後の機器復旧は、所有者が安全に行う清掃の範囲を超えて判断します。
- ⚠ 洪水、下水、浄化槽のあふれ、または明らかに汚染された流出水がプールか機器エリアに入りました。
- ⚠ 電気機器が浸水したか、補給水源も安全ではない可能性があります。
- ⚠ 再開の唯一の理由が水がきれいに見えることなら、それは汚染区分が解決したことにはなりません。
