Evaluation of the water quality of the upper reaches of the main Southern Brazil river (Iguaçu river) through in situ exposure of the native siluriform Rhamdia quelen in cages

This paper shows the results obtained in field analysis performed at the Tamis River, starting from the settlement Jasa Tomic - border between Serbia and Romania to Pancevo - confluence of Tamis into the Danube. The Tamis is a 359 km long river rising in the southern Carpathian Mountains. It flows through the Banat region and flows into the Danube near Pancevo. During the years the water quality of the river has severely deteriorated and badly affected the environment and the river ecosystem. In situ measurements enabled determination of physico-chemical parameters of water quality of the Tamis River on every 400 m of the watercourse, such as: water temperature, pH value, electrical conductivity, contents of dissolved oxygen and oxygen saturation. The main reason of higher pollution of Tamis is seen in connection to DTD hydro system. Sampling was performed at 7 points with regard to color, turbidity, total hardness, alkalinity, concentration of ammonium nitrogen, nitrite nitrogen, nitrate nitrogen, iron, chlorides and sulphates in samples. The aim of the present work was to evaluate water quality in the Tamis River taking into account significant pollution, which originates from settlements, industry and agriculture, and to suggest appropriate preventive measures to further pollution decreasing of the river's water.

Local Water

The lack of clean water distribution by local water service (PDAM) of Palangka Raya city is the major reason for people around the final processing site/landfill (Tempat Pemrosesan Akhir) at Km 14 to use groundwater for their daily life. The landfill may cause pollution over groundwater known as leachate, which commonly unnoticed by its users. This study aims at assessing the quality of groundwater in that area. The groundwater was taken at different distances from the site in three rainless-days. The physical, chemical and biology parameters of groundwater are observed in the field (in situ) and analyzed in the laboratory, refers to water quality standard of Class I, according to Government Regulation No. 82 of 2001 and Minister of Health Regulation No. 32 of 2017. Public opinion on that issue is cached through interview. The results showed that the groundwater around the landfill in three rainless-days was harmless to be consumed as drinking water, and did not exceed the water quality standards stipulated by government in term of odorless, tasteless, and colorless. Some indicators also show that the groundwater meets the specified quality standards, i.e. TDS (17-68.14 mg/L), DHL (17,15-69.39 ?s), turbidity (0.11-2.50 mg/L), iron (0.227-0.71 mg/L), manganese (<0.0123-0.02 mg/L), coliform (<1.8-280 MPN/100 ml), while Pb and H2S were not detected. From community side, there are no any health complaints arise as long as they use the water.

Musi River

Penelitian ini dilakukan untuk mengetahui kualitas air Sungai Musi tahun 2007 sampai dengan 2008 di bagian tengah dan hilir berdasarkan pada sumber polutan. Empat belas stasiun pengambilan contoh ditetapkan sebagai sumber polutan seperti industri maupun pemukiman penduduk, dan referensi yang jauh dari industri maupun pemukiman yang digunakan sebagai pembanding. Pada setiap stasiun, pengambilan contoh dilakukan 3 kali waktu pengambilan, yaitu bulan April, Juni, dan Januari yang dapat mewakili 3 musim yang berbeda pada tahun tersebut. Beberapa parameter diukur in situ sementara beberapa lain dianalisis di laboratorium dengan standar methods (AWWAWEF, 2005). Dari hasil penelitian didapatkan bahwa industri yang bergerak di bidang pengolahan kelapa sawit dan karet cenderung menurunkan kualitas perairan di Sungai Musi. Kandungan logam berat dalam sedimen di Sungai Musi relatif rendah dengan kandungan Cr+6 dan Pb yang tertinggi masing-masing 13,481 dan 1,747 μg per g. Curah hujan cenderung menurunkan beberapa parameter fisika dan kimia kualitas perairan. Potensi pencemaran cenderung ditemukan di bagian hilir Sungai Musi, karena sebaran industri dan intensitas pemanfaatan perairan cukup tinggi di bagian sungai tersebut. Study in order to know distribution of pollution source and its effect on water quality of the middle and down stream of Musi River was conducted in April and June 2007 and January 2008. Fourteen sampling sites were selected based on the pollution source and the minimal degradation site (reference sites). Parameters observed were pollution source distribution and water and sediment parameters such as physical and chemical parameters. Water sample was collected at 0.5 m from water surface by using Kemmerer water sampler while sediment samples were taken by using Ekman grab. Some of the parameters were analyzed in situ while the rest were analyzed in laboratory. Results indicated that oil palm and rubber industries were mostly the pollution source in Musi River. Potential pollution source was mostly found in the middle and down stream of Musi River since most of pollution source and high water utilization found in this area. Water quality parameters except total suspended solid and biochemical oxygen demand, were still in the range that can be tolerated by the aquatic organisms. Rain fall tends to decrease water quality of the river. Concentration of heavy metal such as Chrom (Cr+6) and plumbum in the sediment were in still in low concentration with the highest concentration reaching 13.481 and 1.747 μg per g respectively.

The use of pesticides / fertilizers in plantations has become a problem in maintaining the quality of surface water. Thus, the objective of this study was to evaluate the water quality for irrigation purposes in the Rio Apéu microbasin – Para. The physico-chemical parameters evaluated were: pH, DO, SAR, TDS and EC measured in situ and the metals Al, Fe, Na, Ca, Mg determined in the laboratory Evandro Chagas Institute, according to the method of APHA. The average levels of pH (5.51), OD (5.04 mg L-1) are indications of normal condition in Amazonian waters. The results of Al (332 mg L-1) and Fe (5.74 mg L -1) imply the leaching of sediments from the geological formation of the region rich in these minerals, even though they present values above what is recommended by the legislation. The Richard classification allowed us to define that the waters of the study area have low salinity and sodicity, so they are not restricted to use. Thus, the results of the water quality analysis in the watershed can be concluded that it does not offer environmental problems in the use for irrigation activity
