The mudballs worked because they have been enriched with Effective Micro-organisms (EM), a consortium of “good” microbes that can degrade pollutants (see sidebar) such as those contained within the noxious sludge that chokes riverbeds.
Sounds too good to be true? It is. Before everyone gets all excited over these wonderballs, here are some words of caution from scientists and even EM advocates themselves: they are not a cure-all to the problem of polluted rivers. The efficacy of EM mudballs will not last – not when pollutants continue pouring into rivers.
So while EM can work wonders, many question its long-term viability – particularly in Malaysia where rivers are still a toxic brew of rubbish, sewage, industrial effluent, eroded soils, chemical-laced runoffs from farms, untreated grey water (from kitchens and bathrooms), stormwater and nasty runoffs from wet markets,pasar malam sites, eateries, car washes and car workshops.
