Reclamation Area

In Mohoni Village, East Petasia District, North Morowali Regency there are nickel mining activities that are carried out by PT. Asiamax Mining Indonesia. Several locations were mine out status. Hence, reclamation programs are made to improve environmental conditions before mining. One of these stages is water quality tests to ensure that the reclamation area is worthy to be a habitat for animals and plants. The purpose of this study is to find out the water quality in the reclamation area of the ex-nickel mining in Mohoni Village. The storet method is used to analyze water quality whose test parameters include pH, total suspanded solid (TSS), concentrations of copper (Cu), cadmium (Cd), zinc (Zn), lead (Pb), nickel (Ni), chromium valence 6, iron (Fe), manganese (Mn), and cobalt (Co) once every three months for a year.The quality water check results are compared with the environmental quality standards in accordance with law number 32 of 2009. Based on the average monitoring results show that the water quality is classified as moderately polluted. The conclusion from this study is that reclamation land might be not used as habitat for animals and plants because the availability of water is not suitable for consumption

Abstract. A regional overview of the water quality and ecology of the River Lee catchment is presented. Specifically, data describing the chemical, microbiological and macrobiological water quality and fisheries communities have been analysed, based on a division into river, sewage treatment works, fish-farm, lake and industrial samples. Nutrient enrichment and the highest concentrations of metals and micro-organics were found in the urbanised, lower reaches of the Lee and in the Lee Navigation. Average annual concentrations of metals were generally within environmental quality standards although, on many occasions, concentrations of cadmium, copper, lead, mercury and zinc were in excess of the standards. Various organic substances (used as herbicides, fungicides, insecticides, chlorination by-products and industrial solvents) were widely detected in the Lee system. Concentrations of ten micro-organic substances were observed in excess of their environmental quality standards, though not in terms of annual averages. Sewage treatment works were the principal point source input of nutrients, metals and micro-organic determinands to the catchment. Diffuse nitrogen sources contributed approximately 60% and 27% of the in-stream load in the upper and lower Lee respectively, whereas approximately 60% and 20% of the in-stream phosphorus load was derived from diffuse sources in the upper and lower Lee. For metals, the most significant source was the urban runoff from North London. In reaches less affected by effluent discharges, diffuse runoff from urban and agricultural areas dominated trends. High microbiological content, observed in the River Lee particularly in urbanised reaches, was far in excess of the EC Bathing Water Directive standards. Water quality issues and degraded habitat in the lower reaches of the Lee has led to impoverished aquatic fauna but, within the mid-catchment reaches and upper agricultural tributaries, less nutrient enrichment and channel alteration has permitted more diverse aquatic fauna.
