Mine Wastewater

Jambi is one of the provinces in Indonesia that has an abundance coal potential. One of the companies that holds the Mining-Business License (IUP) for Coal mining production and operations is PT. XYZ, which is chosen to be the source of samples for this research. One of the negative impacts caused by coal mining activities is the wastewater emerge from both mining and stockpile activities. Unprocessed wastewater can pollute the environment, particularly the surface water and ground water around the mining site. Materials utilized in managing coal mine wastewater in this research are bentonite (natural and activated) and limestone from clamshells. Bentonite is expected to be able to absorb TSS, Fe, Mn and Hg values, while clamshells to increase the pH value in coal mine wastewater. This research aims to determine the ability of clamshell bentonite and limestone in processing coal mine wastewater. The samples in this research are amounted to 19 consisting of 1 control sample and 18 treatment samples. The treatments are made in 6 mass variations and 3 variations of contact time. A combination of 1 gram of material is contacted with 250 ml of coal mine wastewater. The characteristics of coal mine wastewater from PT. XYZ based on the samples taken are as follows: pH 4,40, TSS 66 mg/l, Fe 0,998 mg/l, Mn 7,340 mg/l, dan Hg 0,00076 mg/l. The results of this research show that the compilation of bentonite and limestone from clamshells is able to reduce the parameters of coal mine wastewater. The absorption efficiency of the compilation of bentonite and limestone in decreasing the parameters of coal mine wastewater has varied values with the average of: pH 68,62%, TSS 90,91%, Fe 97,60%, Mn 26,71%, and Hg 96,05%. Mass variations and contact time influence the decrease in coal mine wastewater parameters. The treatment on variations of 0.75 grams of activated clamshell bentonite and 0.25 grams of clamshell limestone with 30 minutes contact time is the treatment that produces wastewater that meets the environmental quality standards, which are pH 7,16 from 6 – 9 of environmental quality standards value, TSS 6 mg/l from 400 mg/l of environmental quality standards value, Fe < 0,02 mg/l from 7 mg/l of environmental quality standards value, and Hg < 0,00003 mg/l from 0,002 mg/l of environmental quality standards value. With good management, it is expected that the impacts caused by waste water from coal mining can be minimized in order to achieve environmentally friendly mining activities

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

This research uses normative legal research methods. The approach used is the statutory and conceptual approach. The legal materials used are primary, secondary, and tertiary sources of law. Legal material analysis techniques use description and argumentation. The results of the study indicate environmental quality standards as a boundary measure of environmental pollutant elements. The case of excavation C in Karangasem Regency, the provincial government and the regional government worked together to issue a Mining Business Permit Regulation as a legal regulation that must be obeyed by business people and the community in the excavation environment C. That it has been prohibited from excavating non-metal minerals and rocks in the area with an altitude higher than 500 meters above sea level and curbing the stone mining permit area within the province and sea area for up to 12 miles. Implementation of environmental preservation includes: first, prevention; second, prevention; and third, recovery as a preventive measure for environmental pollution due to mining activities in C. Kegiatan pertambangan dapat meliputi eksplorasi, eksploitasi, produksi, pemurnian, serta penjualan. Seperti yang saat ini diterapkan bahwa pertambangan bisa dijadikan lahan bisnis sesuai revolusi industri yaitu 4.0 (four point zero). Sehingga dengan perkembangan revolusi industri saat ini terdapat berbagai sektor perekonomian salah satunya sektor pertambangan. Pulau Bali memiliki potensi bahan galian C yang terletak di Kabupaten Karangasem. Pertambangan yang ada akibat letusan Gunung Agung dimanfaatkan oleh masyarakat yang pengelolaannya dilakukan dengan penggalian sehingga menghasilkan bahan material yang dapat diperjualbelikan. Tujuan dari studi ini adalah mengkaji baku mutu lingkungan sebagai instrumen pengendalian lingkungan hidup kasus galian C di Kabupaten Karangasem. Penelitian ini menggunakan metode penelitian hukum normatif. Pendekatan yang digunakan adalah pendekatan perundang-undangan dan pendekatan konsep.

Coal is one of the most mining commodities to date, especially to supply both national and international energy needs. Coal mining activities that are not well managed will have an impact on the occurrence of environmental damage. This research tried to utilize the multitemporal Landsat data to analyze the land damage caused by coal mining activities. The research took place at several coal mine sites in East Kalimantan Province. The method developed in this research is the method of change detection. The study tried to know the land damage caused by mining activities using NDVI (Normalized Difference Vegetation Index), NDSI (Normalized Difference Soil Index), NDWI (Normalized Difference Water Index) and GEMI (Global Environment Monitoring Index) parameter based change detection method. The results showed that coal mine area along with the damage that occurred in it can be detected from multitemporal Landsat data using NDSI value-based change detection method. The area damage due to coal mining activities  can be classified into high, moderate, and low classes based on the mean and standard deviation of NDSI changes (ΔNDSI). The results of this study are expected to be used to support government efforts and mining managers in post-mining land reclamation activities.

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.
