Leachate Water

The aim of the research was to determine the quality of leachate water in the processing unit (IPAL) of TPA Sowi Gunung and the quality of surface water around the TPA in relation to the operation of the IPAL TPA.The method used in this research is descriptive method with cross sectional survey technique by collecting leachate samples from the IPAL unit and surface water samples from two springs around the landfill area accompanied by in situ measurements of pH parameters and continued with 6 parameter quality analysis others (TSS, TDS, BOD, COD, N-total, TOC) at the Laboratory of the Center for Environmental Research, University of Papua. The result of the research it is known that the parameters of pH, TSS, BOD, COD, N-total, and TOC in the TPA IPAL unit are categorized as under quality standards (PerMenLHK No.59 of 2016 concerning leachate quality standards for businesses and / or activities for final processing sites trash).In particular, the TDS parameter does not have a tolerance limit corresponding to this quality standard so that it becomes a separate consideration in its management considering that water with a high amount of dissolved solids> 1000 mg / L has an unpleasant taste, so it is not suitable for consumption.Likewise, the quality of surface water at 2 (two) observation points of springs through parameters of pH, TSS, TDS, BOD, COD, N-total, and TOC are categorized as under class I water quality standards according to PP No. 82 of 2001 concerning water quality management and water pollution control.

Drinking water in Ghana is estimated at 79%, but this only represents the proportion of the population with access to improved drinking water sources without regard to the quality of water consumed. This study investigated the quality of household drinking water sources in the Oforikrom municipality where potable water requirements are on the rise due to an ever-increasing population. Both quantitative and qualitative methods were employed in this study. One Hundred households were randomly selected and interviewed on the available options for drinking water and household water treatment and safe storage. A total of 52 points of collection (POC) and 97 points of use (POU) water samples from households were collected for physicochemical and microbial water quality analysis. Amongst the available drinking water options, sachet water (46%) was mostly consumed by households. Water quality analysis revealed that the physicochemical parameters of all sampled drinking water sources were within the Ghana Standards Authority (GSA) recommended values expected for pH (ranging from 4.50 to 7.50). For the drinking water sources, bottled (100%, n = 2) and sachet water (91%, n = 41) showed relatively good microbial water quality. Generally, POC water samples showed an improved microbial water quality in comparison to POU water samples. About 38% ( n = 8) of the households practicing water quality management, were still exposed to unsafe drinking water sources. Households should practice good water quality management at the domestic level to ensure access to safe drinking water. This may include the use of chlorine-based disinfectants to frequently disinfect boreholes, wells and storage facilities at homes.

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

Ceriodaphnia Affinis

Formulation of the problem. Regulation of hazardous chemicals admission to surface water is carried out by means of appropriate water quality standards. Researching the systems of surface water quality regulation in different countries, it has been determined that there is a tendency to use standards for the protection of the aquatic ecosystem and for meeting the needs of society and industries - environmental quality standards. Such standards are based on obtaining ecotoxicological information of a dangerous chemical substance on the representatives of the aquatic ecosystem. Among them, some of the most sensitive test organisms are crustaceans from the Daphniidae family. They are used to establish water quality standards for chemicals, to assess the quality of wastewater and surface water using a toxicological indicator. It is recommended to use a standardized international methodology to assess effects of chemicals on Daphnia magna Straus (OECD No. 202) to establish environmental water quality standards in EU countries. However, in Ukraine, in water protection practice, the most popular test organism is Ceriodaphnia affinis Lilljeborg (Daphnia sp.). The purpose of the article. In order to set ecological standards for water quality of chemicals in Ukraine, the authors proposed to test the OECD No. 202 methodology using Ceriodaphnia affinis test organisms and to establish metrological characteristics for it. Presentation of the main research material. The authors tested the OECD methodology No. 202 [21] on the crustacean culture Ceriodaphnia affinis from the culture collection of the Laboratory of Ecological and Toxicological Research, the V. N. Karazin KhNU. The coefficient of variation of EC50-24 and EC50-48 K2Cr2O7 was 16,8 % and 15,9 % respectively. Based on the data obtained, the metrological characteristics of the tested method were established: the response range of the test organisms Ceriodaphnia affinis is the following – 1,45<EC50-24 <2,91 (mg/dm3); reproducibility of the results of determining the toxicity of a chemical substance – 0,18 mg/dm3 (16,1%); the error in the results of determining the toxicity of a chemical substance – 0,34 mg/dm3 (31.6 %); standard of operational control – 0,49 mg/dm3. Scientific novelty and practical significance. The findings confirm the possibility of using Ceriodaphnia affinis in a short-term test in setting environmental water quality standards in Ukraine.

In order to investigate the effects of mining pollution to LongJiang River and to know the situation of LongJiang River, we collected water and sludge samples along the river and analyzed the heavy metal content of samples. Results showed that LiDeFen factory and JinHe mining released most of the heavy metals to LongJiang River two years ago, and the upstream of LongJiang River also released some metal to the river. These heavy metals were precipitated to the bottom of LongJiang River by using weak alkaline chemical precipitation technology, and water quality of LongJiang River can reach the second national environmental quality standards of surface water now. The precipitation effects were different in different remediation sites.
