Abstract
The case of 22 deaths in LaeMaromas, North Sumatera suspected due to water contamination by nearby metal mining was brought by local citizens to the Church-supported non-governmental organization (NGO) Persekutuan Diakonia Pelangi Kasih (PDPK). The patients’ clinical symptoms were fever, shivering, shaking chills, abdominal pain, diarrhoea, and vomiting. In June 2011, a team from the District Health Department analysed the drinking water quality, especially microbiological contamination. Members of PDPK asked the German-Indonesian Medical Association to conduct a second complete water analysis with focus on heavy metal content. Six water samples from four different wells in LaeMaromas and two from Sopokomil and Bongkaras were analysed according to international water quality standards. Taste, odour, colour, and turbidity were determined by organoleptic and photometric methods. Temperature and pH were measured with a calibrated thermometer and pH-meter. Total dissolved solids were determined gravimetrically, hardness as CaCO3 content. Inorganic anions and nitrogen compounds were measured by titration. Contamination with Eschericia coli and coliform bacteria, organic compounds and detergents was determined according to standard methods. Heavy metals were measured by atomic absorption spectroscopy. The pH of the water (4.5-6.5) was below standard (6.5-8.5). Heavy metals were within the allowed concentrations. All samples from LaeMaromas contained high counts coliform bacteria /E. coli with a peak of 1600 counts/100 mL and high organic compound level of 63 mg/L in LaeMaromas III. Most probably, the 22 deaths were caused by drinking water contamination with coliform bacteria rather than by heavy metals or other chemicals.
