The Impact

Digoel river have an important role to the human activity and environment in Boven Digoel Regency. Increasing of human and industrial activity around the watershed of Digoel River were suspecious to cause the degradation water quality in Digoel River. This research was done to monitor the impact of the industrial activity to the quality of water in outlet of waste water treatment plant(WWTP) of PT. Korindo to the water quality of Digoel River. Parameter analised are the physical, chemical, organic chemical, microbiology and metal content in water. Analysis of the water quality accordance to PP Nomor 82 Tahun 2001 about water quality managementand water pollution and Permen LH Nomor 5 tahun 2014 about the quality of waste water.The monitoring was conducted in three months at five sampling stasion (river upstream, river down stream, outlet WWTP plywood, outlet WWT workshop, outlet WWTP palm oil) in Districk Jair. The rsult showed, parameter of BOD, COD, phospate, phenol and total coliform in Digoel River exceeded class I of water quality standards. Outlet of plywood WWTP have two parameters that exceed the quality standard which were TSS 15.67 mg/L and phenol 13.33 mg/L.The outlet of WWTP workshop have four pameter exceeded the quality standard which were TSS (383.67 mg/L), oil/fats (502.0 µg/L), phenol (11.0 µg/L), and zinc (21,000 mg/L). IPAL oil WWTP outlet have two parameter sexceeded the quality standars which were oil/fats (313.0 µg/L) and total coliform (> 979 cells/100 mL). The result indicating  that the status of water quality of Digoel River are categorized as “lightly polluted”. Therefore based on utilization, it was categorized as class IV water quality that can be used for irrigating, planting and other purposed that meet the requairement of water qualiy in this class, while for other uses need necessary processing. In order  not to  increase the pollution in the Digoel river the WWTP of industry around Digoel River should improved their treatment, so that waste water discharged to the Digoel River not exceed the stanards quality.Key words: water quality, digoel river, status of water quality, pollutant index.

Abstract The general approach to water quality studies in Gulf Canada petroleum refineries is described and illustrated by typical results from one refinery. Some of the studies were carried out using a Mobile Water Conservation Laboratory on site whilst others involved grab sampling and transportation to a central laboratory. The studies were carried out with the objective of evaluating the efficiency of existing waste water treating systems to produce effluent of quality which will meet modern environmental requirements set by the Federal Government. These include oil, suspended solids, sulfide, ammonia, phenols, pH and a fish toxicity requirement. The quality of the effluents of several large and complex refineries was monitored, performance of waste water treating units was determined and pilot plant data of new packaged units was collected for future uses. Emphasis was placed on treating units which are used to treat waste streams and effluents for oil and suspended solids removal.

Zero Condition

Construction of the silica material factory named "R-S Silicon", with an annual production capacity of15,210 ton of Si-metal, was planned in the village of Bjelajce, municipality of Mrkonjić Grad. The factoryfor production of Si-metal shall have direct and indirect environmental impacts, especially on waters, bywashing off working areas, leachate and other waste water that must be treated due to contamination, so thattheir quality would be at least the quality of surface recipient into which they are discharged.Before the construction, i.e. commissioning of subject factory, it is necessary to determine the zerocondition of waters quality around the factory in order to have a realistic picture of its impact on the waterquality during its operation.

Modrac hydroaccumulation is the largest and most important multi-purpose water resource for watersupply to large industrial capacities of importance for Bosnia and Herzegovina, but also for public watersupply of Tuzla and Lukavac. Since the water quality of the hydroaccumulation is threatened by thewaste water of a large number of different pollutants in the basin area of 1.189 km², and that the usefulvolume of hydroaccumulation is limited, then during the time it comes to the filling of thehydroaccumulation dominated by coal dust from coal mines in the basin reservoirs. It must be ensuredthat good quality water is supplied to consumers, especially households and industries, while ensuringhydrobiological minimum dilution of waste water discharged into the river Spreča downstream fromdam and reservoir Lukavac.
