Visarjan Ghat Watch

Bhopal ghat water-quality screening for Durga visarjan planning · Durga visarjan: Tue 20 Oct 2026

Method & limitations

Backend output from the supplied 2023–2025 data. Computed by the Visarjan Ghat Watch backend (Python, tested) from the supplied MPPCB readings for 2023–2025 and the CPCB criteria file. Not live data. There are no 2026 measurements. Report page references come from the data file. Only a partial manual spot check has been done against the PDFs; other page references are not yet checked.

  4. Data gapBackend output· ranking.py

    Some DO, BOD or pH readings are missing. Missing is not treated as passing; a gap adds a sampling action instead.

    • No reading for BOD in 2023 Durga (pre, after); BOD, pH in 2023 Durga (during). Missing data is not counted as passing.

Recommended actions

From the backend action rules (config/action_rules.csv), matched to this ghat's flags. Recommendations for officer verification, not instructions.

Backend output· action_rules.csv
  1. Water sampling·Because:Data gapRecommendation — verify

    Priority pre-immersion sampling before 20 Oct: DO, BOD, pH and total coliform (past readings are missing).

    When: 13–18 Oct(D-7 → D-2)Recommendation — verify with MPPCB / CPCB guidelines. Source: team recommendation (follows from the data gap).
  2. Water sampling·Because:pH outside rangeRecommendation — verify

    Test pH before immersion and report the reading to the relevant MPPCB laboratory.

    When: 15–20 Oct(D-5 → D)Recommendation — verify with MPPCB / CPCB guidelines. Source: team recommendation.
  3. Barricading & nets·Because:All ghatsRecommendation — verify

    Contain floating material with barricades, nets or booms; consider a liner or temporary pond where applicable.

    When: 15–20 Oct(D-5 → D)Recommendation — verify with MPPCB / CPCB guidelines. Source: team recommendation; to verify against CPCB idol-immersion guidelines.
  4. Aeration·Because:DO below 4Recommendation — verify

    Start aerators at the immersion zone before immersion and check dissolved oxygen (DO) daily with a portable meter. If DO stays below 4 mg/l before 20 Oct, refer to the officer to review an alternative immersion kund.

    When: 17–27 Oct(D-3 → D+7)Recommendation — verify with MPPCB / CPCB guidelines. Source: team recommendation.
  5. Cleaning & debris·Because:BOD often above 3Recommendation — verify

    Collect flowers and organic offerings separately before immersion; remove idol remnants and debris after immersion; inspect for drains entering the water body.

    When: 18–22 Oct(D-2 → D+2)Recommendation — verify with MPPCB / CPCB guidelines. Source: team recommendation; to verify against CPCB idol-immersion guidelines.
  6. Water sampling·Because:All ghatsRecommendation — verify

    Collect DO, BOD, pH and total coliform samples one week after immersion.

    When: 27 Oct(D+7)Recommendation — verify with MPPCB / CPCB guidelines. Source: team recommendation; timing follows MPPCB's one-week-after sampling (participant guide).

Target for the 27 Oct sample

PRD v2 §7.1 defines four statuses for the one-week-after sample. This tool does not assess new samples yet; none of the statuses is a clearance.

Backend output· criteria CSVPRD v2 rule· §7.1

Sample due: Tue 27 Oct 2026

Current status: Not yet assessed: the one-week-after sample is due on 27 Oct 2026. There are no 2026 readings in the supplied data.

Checklist

  • Dissolved oxygen 5 mg/l or more
  • BOD 3 mg/l or less
  • pH 6.5 to 8.5
  • Total coliform 500 MPN/100 ml or lessNot in current data; needs a new test

Possible statuses after 27 Oct

Meets measured Class B criteria
DO, BOD and pH all within limits in the one-week-after sample. Total coliform still needs a test to confirm Class B.
Back to pre-immersion level (interim)
Fails Class B, but DO is at or above and BOD at or below that season's pre-immersion reading.
Does not meet
DO, BOD or pH outside limits and worse than pre-immersion.
Cannot assess
DO, BOD or pH missing from the sample.

BOD was already above 3 mg/l in 32 of 37 pre-immersion readings (2023–2025), so full Class B by 27 Oct is unlikely at most ghats. The interim target does not replace Class B.
