The Palm-Oil Mill and the Village Well
About 1,800 people live in a village 6 km from a small palm-oil mill. The mill began operating eight months ago and discharges dark, pungent effluent into a seasonal stream that villagers use for washing. In the last month the health post recorded 12 cases of diarrhoea among children under five and several cases of skin rash. The village borehole is 25 m from a public latrine, and a field test shows nitrate levels above the national guideline. The mill owner says he employs 35 young people and holds a land-use authorisation from the council. The council says it has no laboratory and did not licence the discharge. The sub-divisional officer asks the district medical officer and the environment delegation for a report. Meanwhile, the mill continues to operate 24 hours a day.
1. Rank the likely health and environmental risks and explain what evidence you would need before blaming the mill for all of them.

Rank the risks by urgency and reversibility. First, drinking-water contamination: 12 diarrhoea cases in a month among under-fives and a borehole 25 m from a latrine suggest a faecal-oral route; the nitrate result points to sewage or organic waste, not necessarily the mill. Second, direct contact with effluent: skin rashes among people washing in the stream are consistent with irritant or bacterial contamination. Third, long-term river and soil damage.
But blame requires evidence. The mill may be a source, yet the latrine is a separate and more immediate hazard. You would need water samples upstream and downstream, a sanitary inspection of the borehole, stool and skin-swab results, and the mill's discharge volume and composition. A single field test is not enough. The correct reasoning is precautionary: stop exposure now, investigate in parallel, and do not let the presence of 35 jobs become a reason to leave children exposed.
2. Which public authorities and legal instruments are relevant, and what can each realistically do?
Read the worked answer
The divisional delegation of the environment ministry can inspect the mill, require an environmental impact assessment or a compliance certificate, and apply the polluter-pays principle under the 1996 environmental management law. The district medical officer can investigate the disease cluster, test water, and order a temporary alternative water supply. The council can check land-use and local hygiene rules, but a land-use authorisation is not an environmental licence. The sub-divisional officer can coordinate and, if necessary, order a temporary suspension under the law. The justice system can prosecute serious pollution.
Realistically, the environment delegation may lack a laboratory, so it should send samples to a regional laboratory and record the chain of custody. The council should not claim it has no role: it is closest to the market and the village. A joint inspection with written minutes is more useful than separate letters.
3. Propose a sustainable plan that protects health without destroying the 35 jobs.

The plan should separate emergency, medium-term and long-term measures. Emergency: provide safe water by trucking or chlorination, treat the skin cases, and stop washing in the stream. Medium-term: require the mill to build a settling and treatment system, monitor discharge monthly, and relocate or rebuild the latrine at least 30 m from the borehole with a sealed pit. Long-term: create a community environmental committee with the mill, council and health post; sign a written agreement that the mill funds monitoring and a water point; and publish results.
The 35 jobs should be protected by making the mill comply, not by closing it permanently. If the owner refuses, temporary suspension is justified. Sustainable development is not a slogan here: it means the village keeps both the wages and the river, not one at the expense of the other.
