Fluoride, Funds and a Five-Month Deadline: Prioritising Drinking-Water Works
The District Magistrate of a drought-prone Bundelkhand district receives a Jal Jeevan Mission review on 12 March. Fourteen habitations across six Gram Panchayats draw groundwater with fluoride at 2.8-3.4 mg/L against the permissible 1.5 mg/L; 8,400 residents are affected, including 1,100 schoolchildren. Forty-seven cases of skeletal fluorosis are reported from two villages, and the CMO has flagged dental mottling among children in five. Two community reverse-osmosis plants were commissioned in 2019. One is dead because of a burnt pump motor; the other runs at about 38% capacity because the panchayat charges Rs 4 per litre, which most households will not pay, so they keep drinking hand-pump water. The district has Rs 1.9 crore sanctioned and five months before the monsoon. A surface-water source nine kilometres away tests 0.6 mg/L, but the pipeline estimate is Rs 4.3 crore. Nalgonda defluoridation units cost Rs 18 lakh each and need a regular alum supply and a trained operator. The local MLA demands a new RO plant for his village of 3,000; the water-quality register has not been updated for two months.
1. Prepare a costed five-month action plan. State the allocation and the criteria that decide priority between the MLA's demand, the dead RO plant and the pipeline.

Rank first, spend second. Priorities should follow (i) confirmed health injury, especially among children, (ii) fluoride concentration and duration of exposure, (iii) persons brought below 1.5 mg/L per rupee per month, (iv) speed within the five-month window, and (v) whether the asset will still work after the money is spent. On these tests the two villages with 47 skeletal fluorosis cases rank first; the MLA's village, with high fluoride but no reported cases and a nearer alternative source, ranks fourth.
Allocation of Rs 190 lakh
- Rs 12 lakh: repair or rewind of the dead RO pump, solar backup, and an annual maintenance contract with a one-week response clause.
- Rs 72 lakh: four Nalgonda units (Rs 18 lakh each) for the two worst villages and two school clusters, with twelve months of alum and a paid operator.
- Rs 55 lakh: tanker supply and safe-water cards for the three most exposed habitations until the monsoon, and a cut in the user charge from Rs 4 to Rs 1 at the working plant.
- Rs 25 lakh: exploratory borewell and aquifer mapping with the CGWB to locate a low-fluoride stratum.
- Rs 18 lakh: ion-selective field kits, quarterly third-party sampling, and digitisation of the register.
- Rs 8 lakh: school and anganwadi IEC.
The Rs 4.3 crore pipeline cannot be built in five months, so fund only its DPR from the district plan and push the capital case to the State under the sustainability window rather than committing the whole allocation to a single asset.
2. The MLA argues that a new RO plant is the only 'permanent' solution. Evaluate that claim against the hydrogeology and the district's O&M record.

What RO does and does not do. RO is dilution-and-rejection. At 55-65% recovery, a feed of 3.2 mg/L leaves a reject stream of roughly 5-8 mg/L which must go to lined evaporation pits or a sewer; in a village on a declining aquifer the reject is often dumped near the same recharge area and re-enters the source. The plant also needs uninterrupted power, membrane replacement every 24-36 months, and an operator who can read a TDS meter and log it.
The district's own record is the decisive evidence. Of two plants commissioned in 2019, one is dead on a burnt motor and the other runs at 38% because a tariff of Rs 4 per litre prices out the very households that need it. A third plant would reproduce the same failure mode unless the tariff and the maintenance contract are fixed first.
Durable alternatives sit at the source. Blending the 3.2 mg/L source with the 0.6 mg/L source at roughly 1:2 brings the mix to about 1.5 mg/L; roof rainwater harvesting can cover drinking water in schools; recharge structures reduce concentration over time. Nalgonda units are acceptable as an interim measure because they are locally repairable, but the alum dose must be controlled, residual aluminium tested, and sludge dried on a bed.
The MLA's demand should be answered with utilisation and downtime data, not with a refusal in principle, and any new plant must come with a written O&M arrangement funded from user charges.
3. Which monitoring indicators would you fix, and how would you handle the missing water-quality register?

Indicators for the monthly review
- Percentage of habitations with fluoride at or below 1.5 mg/L, tested monthly at the same draw point.
- Percentage of habitations with a safe alternative source within 500 metres.
- Plant downtime in hours per month, and the share of O&M cost recovered from user charges (target at least 30%).
- Litres of safe water actually consumed per household per day, measured by card swipe or tanker log rather than by design capacity.
- New fluorosis cases in school health screening and dental mottling among children under twelve.
- Percentage of samples uploaded to the JJM dashboard within seven days.
The missing register. A two-month gap in a fluoride-affected district is itself a finding. Order a one-time census of all fourteen sources by a team that excludes the concerned junior engineer, with GPS-stamped photographs and laboratory reports; record it as an administrative lapse unless samples were falsified, in which case draw a disciplinary or criminal consequence. Publish the results on the panchayat notice board and the district website, because the credibility of the technical fix depends on the household believing the number. The review should also fix accountability for the dead RO plant, since the same officer will otherwise certify the next one.
