A good water quality is essential to sustaining the life of the organisms. The determination of water quality is needed as a direction to monitoring the water pollution. The purpose of this study is to examine the quality of the water and to determine the water pollution index based on the physicochemical parameters in Mimika waters, Indonesia. The sampling of water quality was carried out in October 2016 at six stations (Moga, Puriri, Inaoga, Keakwa, Atuka and Pomako waters). Then, the results were compared with the standard of sea water quality for biota marine based on the Decree of the Minister of Environment No. 51 year 2004. This study showed that the physicochemical parameters of the waters, such as water turbidity, BOD, NH 3 and heavy metals (Hg, As, Cd, Pb, Cu, Zn, Ni and Cr), are still appropriate to the biota marine in all study stations. However, there is a parameter for which the quality standards were exceed in all locations, including water salinity for coral and seagrass, NO 3 , PO 4 and H 2 S. The result of pollution index calculation at coastal waters Mimika are classified as lightly polluted (Keakwa and Pomako waters), and moderately polluted (Moga, Puriri, Inaoga and Atuka waters) with the pollution index values of 3.51 to 6.95. It is important to notice that the parameters of quality standards which had been exceed such as NO 3 , PO 4 and H 2 S are the environmental parameter for nutrient elements and can trigger eutrophication in the waters.

“…It is noteworthy that some individual quality parameters are at very high levels of standardized WQI quality indices, reaching values close to the maximum limit for both rivers: DO and 99 phosphates, nitrates 97, BOD 96 respectively 94.Globally, with WQI values of 88 versus 85.25, the two rivers fall into the Good Water Quality category (70-90) and thus with minimal technological potable operations -category A1, ensures good water supply of the population of Targu Jiu City. http://www.revistadechimie.ro The WQI level for the two mountain rivers ranging from 88-85.25 is within the variation limit of some rivers in Romania such as Timis River (2004-2014), at six sampling points with values of 81-86 [13]; Motru River 2000 -2009 with values between 80-88 [21], and over the variation level of other rivers in the country such as: Bahlui rivers with WQI between: 53.893 -64.345 [1]; Miletin River with WQI varies between 64-78, Halceni Dam range 65-82, Vlădeni Pond 61-81, Larga Jijia 59-81 and Jijia River 41-61, [20].…”

“…Parameters analyzes that determine the quality of surface water bodies follow the main quality indicators according to quality standards, thermal regime and acidification, oxygen regime, nutrients, salinity, specific toxic pollutants of natural origin, other relevant physicochemical and biological indicators. Most water quality assessment studies generally use reports of the maximum admissible concentrations in relation to national, international or statistical and mathematical models, among which are the Water Quality Index (WQI), the Water Pollution Index ( WPI) and river habitats survey (RHS) [7][8][9][10][11][12][13].Rivers are the main source of drinking and industrial water in Romania. The main rivers that have the upper basins in the high mountain area of Gorj have high annual average flows, provide natural water supplies or are sources of water supplies for towns and rural communities.…”

Water quality criteria are all physicochemical and biological indicators that characterize a body of water. The current study aims at investigating the quality of two natural waters in the Gorj County sub-mountainous area (Şuşiţa, Vaidei and Runc, capture Runc) used as drinking water sources of Târgu-Jiu. Sampling and determinations use spectrophotometric, gravimetric, volumetric or electrometric techniques in accordance with standard methods (SR ISO and / or SR EN) for a series of physicochemical indicators analyzed between January -December 2017: thermal and acidification, oxygen regime, nutrients, salinity, relevant pollutants. Experimental values, annual averages related to the quality standards for potable water, ecological status and classification of water bodies, place the water of the two rivers in the drinking water category A1 and the first class of ecological quality. The Water Quality Index (WQI) for 9 selected parameters highlighted a sensitively close overall level of the water of the two rivers Şuşita (88) and Runc (85.2), the good quality category (7o-9o), reported to national quality standards for surface water which can be used for delivery as drinking water.The study of indicators of the two rivers in relation to national rules aligned with the European water requirementsand research shows a high qualitative status corresponding to community uses. Keyword: physicochemical parameter, water quality indicators, Șușița, Runc, water quality indexWater quality requirements vary depending on the demand for drinking water for human consumption or industrial water. Depending on the nature of the raw water and the sector of use, the resources are selected and the degree of treatment of raw water.Fresh water represents a very low percentage of the Earth's total water content, ie 2.5% of surface water, but only 0.6% is directly accessible through springs, rivers, lakes, underground waters as vital resources for the current population [1].As a renewable, vulnerable and limited natural resource, water is considered a natural heritage that must be protected and preserved. The importance of water quality conservation has led to the monitoring and assessment of watercourses at regional, national and European level [2].According to the requirements of Law 310/2004 and 311/2004 [3, 4], which took over the provisions of the Water Framework Directive 60/2000 / EEC [5] and other EU Directives, the national water monitoring system comprises two types of monitoring: surveillance and operational monitoring surveillance applied to bodies of water at risk of failing to meet water protection objectives. From the point of view of the environmental indicators, the surface water body in Romania in the year 2018 is in moderate 45% and high 55% [6].Water quality assessment can be defined as assessing the physical, chemical and biological nature of water in relation to natural quality, human effects and intentional uses. Parameters analyzes that determine the quality of surface water bodies follow the main quality ind...

Grenjeng River is one of the irrigation water resources which is currently polluted by waste from industrial, livestock and domestic activities. This study aims to assess the quality and index of water pollution based on physical-chemical and biological parameters in the Grenjeng River, Boyolali Regency. Sampling of river water was carried out in dry and rainy seasons which were taken at three observation stations (upstream, middle stream and downstream). Results from laboratory analysis were compared with water quality standards according to Government Regulation No.82/2001, and quality status was based on the Pollution Index method in accordance with the attachment to Minister of Environment Decree No.115/2003. This study shows that BOD of 53-5.7 mg L-1, COD of 49-510.5 mg L-1 and total coliforms of 540-2,400,000 mLin dry season have exceeded the quality standard water classes, while in rainy season total coliforms 24,000-240,000 mLhave exceeded the standard water for all water classes. The pollution index of the river water in dry season has reached polluted to extremely polluted levels and the index of the river water in rainy season has reached moderately polluted to polluted levels. This condition shows that the practice of dumping waste into river bodies can directly affect river water quality. The irrigation water source for agricultural must comply with irrigation water quality standards so that is suitable as irrigation water for plants. Environmentally friendly approach is needed to prevent worse pollution, which is done by increasing public awareness and business actors in managing liquid waste by making the integrated wastewater treatment system.
