Abstract Water is a social requirement and an important factor in the ecological balance. Water from wells is good for direct consumption if the soil is not contaminated. The quality of drinking water is regulated by Law no. 458/2002 (transposing the Directive 98/83/EC on the quality of drinking water). The aim of this paper was to assess the physicochemical qualities of groundwaters from Brestea village, commune Denta, Timis County. The water samples were taken in 2015 from 10 functional wells. For the source whose physical and chemical parameters have exceeded the limit values, the monthly monitoring of the water quality (microbiological and physico-chemical properties) has been performed for 2 years. At the same time, the pH of the soil near the water sources was also measured. The results highlighted a good connection between the microorganisms from water and the nitrite, nitrate and ammonium content of water. The information can be further used to identify and eliminate the specific pollutants, areas and pollution sources.

The ecological impact of human settlement on the water quality of Lower Cross River, Nigeria was evaluated. The physical and chemical conditions of the river water were determined from January to August, 2011. Three stations comprising Itu in Akwa Ibom State with intense human activities (station 2), its upstream (without human settlement) at Cross River State (station 1) and the downstream (station 3) were sampled. The Parametric One Way Analysis of Variance (ANOVA) indicated that of the 17 physical and chemical parameters determined, only water level and COD were found to be significantly different () among stations. The spatial variations in the level of significant correlation of the physical and chemical parameters among the stations and the higher level of interrelationship in downstream station 2 and 3 than station 1 could be attributed to inputs resulting from human settlement. Comparison between some parameters with Standard Organization of Nigeria, and World Health Organization maximum permitted levels for drinking water indicated that the water was not polluted. However, the BOD and COD concentrations of greater than 2 mg/L and 20 mg/L respectively were indicative of pollution.

Water quality monitoring is of great importance in managing drinking water lakes or reservoirs. However, developing such an effective monitoring system used in evaluating water quality is difficult, due to spatial and temporal variation in water quality that are usually hard to interpret. Principle component analysis (PCA) and canonical correlation analysis (CCA) techniques were used in this study to determine the principle water parameters, and explore the relationship between the physical and chemical water parameters, respectively in Macau Main Storage Reservoir (MSR) that is experiencing algal bloom in recent years. Twenty-eight water parameters including physical and chemical parameters were monitored each month from Jan 2001 to Dec 2010. The results showed that using PCA, six of the water quality parameters were found less important in explaining the monthly variation of the water quality and thus excluded from the further CCA, while applying CCA, the first six canonical correlations were 0.998, 0.988, 0.937, 0.778, 0.606 and 0.453, indicating that electro-conductivity and chloride compounds were the dominant (highly scored) variables of the physical parameters and chemical parameters, respectively. These results are helpful in understanding the main physical and chemical parameters involved in MSR, thus improving the water quality monitoring system in drinking water reservoirs.

The article presents the results of the study of the physical and chemical parameters of water for different methods of feeding the commercial young blue fox. The research was carried out at a private brewery in the Khmelnytskyi Ds. on 500 moths of the main herd. Spraying the youngsters of the experimental group was carried out in a traditional way – fom combined drinking water, distribution of water was carried out daily manually. Animals of the experimental group were injected using an automated watering system. Water samples were taken from: a water pipe, from combined drinking water for an hour and 12 hours after hand delivery – in the control group, from self-steering racks for maintenance of fur animals – in the experimental group. An analysis of the dynamics of physical and chemical parameters of water (odor, color, turbidity, rigidity, active acidity, dry residue and chlorides) was carried out for different methods of watering, and compliance with their current norms for drinking water for farm animals was established. In the course of experimental studies, there were significant differences in the organoleptic parameters and water properties in the control group as compared to water samples. Thus, for manual distribution of water for 12 hour there was a deterioration of odor on 1.1 points, increase turbidity almost twice, decrease in acidity – by 1.06 units. The indicated indicators exceeded the maximum permissible norms. The reasons for violations of the quality of drinking water in the traditional way of drinking were: contact with feed mixes in combined drillers, the effect of abiotic and biotic factors, staining residues. In samples of water in the experimental group there were no significant deviations of physical and chemical indices: they were within the limits of permissible norms. Isolation of drinking water from the environment, dosing at the need of the animal proved to be the main advantages of the atomized method of drinking fur-bearing animals, which gives grounds to recommend it for introduction into production. Further scientific research will focus on the study of the microbiological characteristics of water for different ways of drinking fur-bearing animals and, in fact, blue fox. In addition, interesting from a practical point of view can be the study of productive indicators of commodity young animals of fur animals with different methods of watering. It should take into account not only the dynamics of animal growth, the quality of fur, the level of preservation, but also production costs, including changes in the structure of the cost of fur.

Physical and Chemical Parameters of Water Fish Pond Black Nile Tilapia (Oreochromis niloticus) Water is a natural resource that is essential for the survival of humans and other creatures, role of water is essential for life on earth, especially fish in the water habitat. Fish need a comfortable environment in order to be healthy and growing optimally. Therefore, the water, used as a habitat of life for the fish, have certain requirements. So the quality of the water must be very noted. Tilapia is a freshwater fish that has a great tolerance towards the environment, therefore it is highly appreciated by fish farmers in Indonesia.  Study of physical and chemical parameters in water of  tilapia fish pond was done due to lack of review of water quality of tilapia fish pond. The review is based on a sampling of water, i.e. morning and afternoon. A review of the pond water quality was expected to assist fish farmers got information about the qualities of water of tilapia fish pond in physical and chemical characteristics.  The method of this research was Grab (momentarily) methods in water sampling. Testing of water samples in physics done visually for color parameters, temperature using a thermometer device, and brightness parameters was using the secchi disk. In testing the chemical parameters were measurement of pH was using a pH meter Winkler method was done  for the parameters of dissolved oxygen (DO). Titrimetric method was done  for the parameters of  total hardness, and  carbon dioxide, whereas for ammonia parameter was done  by spectrophotometric method were measured using UV-Vissible. After testing all the parameters then interpretation was done for the parameter data.  The results showed the water quality of tilapia fish pond in the area Laladon – Bogor was not  yet qualified for a good fish pond water based on ISO 7550: 2009 Product ion of tilapia growing  level in calm water pond,  for parameter Ammonia levels should be <0.02 mg / L, and based on PPNo.8, on water Quality Standard by 2001. The difference in the parameter levels in the morning and during the day due to the process of respiration at night by the aquatic organisms that produce CO2 gas and the process of photosynthesis during the day by plankton, microalgae, and other aquatic plants to produce a compound O2. The existence of other human activities during the day also affects the difference in the data levels in the morning and day time.Keywords: Tilapia, pond water qualityABSTRAK Air merupakan sumber daya alam yang sangat penting bagi kelangsungan hidup manusia dan makhluk lainnya, Peranan air sangat penting bagi makhluk hidup di bumi terutama ikan yang berhabitat di dalam air. Ikan membutuhkan lingkungan yang nyaman agar dapat hidup sehat dan tumbuh secara optimal. Oleh karena itu  air yang digunakan sebagai sumber kehidupan bagi ikan, memiliki persyaratan tertentu. Sehingga kualitas dari air harus sangat di perhatikan. Ikan nila merupakan ikan air tawar yang memiliki nilai toleransi yang besar terhadap lingkungannya sehingga sangat diminati oleh petani ikan di Indonesia. Studi parameter fisika dan kimia pada air kolam ikan nila dilakukan karena kurangnya peninjauan terhadap kualitas air kolam ikan nila. Peninjauan tersebut dilakukan berdasarkan waktu pengambilan sampel air, yaitu pada pagi dan siang hari. Peninjauan kualitas air kolam diharapkan dapat membantu para petani ikan mendapatkan informasi mengenai kelayakan kolam ikan nila secara fisika dan kimia.  Metode yang dilakukan penelitian ini adalah metode Grab (sesaat) untuk pengambilan sampel air. Pengujian sampel air secara fisika dilakukan secara visual untuk parameter warna, suhu dengan menggunakan alat pengukur suhu, dan metode secchi disk untuk parameter kecerahan. Pada pengujian parameter kimia dilakukan pengukuran pH dengan alat pengukur pH. Metode Winkler dilakukan untuk parameter dissolved oxygen (DO). Metode titrimetrik dilakukan untuk parameter s kesadahan total, dan karbondioksida, sedangkan untuk parameter ammonia dilakukan dengan metode spektrofotometri yang diukur dengan menggunakan alat spektrofotometer UV-Vissible. Setelah dilakukan pengujian semua parameter maka dilakukan interpretasi data hasil penelitian.  Hasil penelitian menunjukan kualitas air kolam ikan nila di daerah Laladon – Bogor belum memenuhi syarat untuk air kolam ikan yang baik berdasarkan SNI 7550:2009 Produksi ikan nila tingkat  pembesaran di kolam air tenang, untuk parameter Ammonia dengan kadar <0,02 mg/L, dan  berdasarkan Baku Mutu PPNo.82 tahun 2001. Terjadinya perbedaan kadar pada pagi dan siang hari dikarenakan terjadinya proses respirasi pada malam hari oleh organisme air sehingga menghasilkan senyawa CO2 dan terjadinya proses fotosintesis pada siang hari oleh plankton, mikroalga, dan tanaman air lainnya sehingga menghasilkan senyawa O2. Adanya aktifitas lain pada siang hari juga mempengaruhi terjadinya perbedaan kadar pada pagi dan siang hari.Kata kunci : Ikan nila, Kualitas air kolam

The present study investigated the probable influence of latrines and groundwater flow on the water quality of shallow tube wells in Shinduria village (23?52' N and 90?14' E) of Dhaka district, Bangladesh. A questionnaire survey was made to collect basic information on tube wells and latrines. Four boreholes were drilled to investigate lithostratigraphy. Twenty one water samples were collected and their physico-chemical parameters (Dissolved Oxygen, pH, phosphate, sulphate, nitrate, nitrite and iron) were analyzed using standard method. Total viable bacterial count (TVBC), total coliform count (TCC), total faecal coliform count (TFCC), total salmonella shigella (TSS) and total vibrio count (TVC) were also made using membrane filtration method. Average depth of the tube wells was 120 ft and most of them were less then ten years old. About 85% latrines were ring slab type and about 50% of these were built during the last five years. From borehole data, a shallow aquifer was identified at a depth of hundred feet from where local people extract drinking water. Although most of the physico-chemical parameters of the tested samples were within the Department of Environment (DoE). But almost all of the tested samples failed to ensure the quality of acceptable level for drinking water recommended by World Health Organization (WHO) due to the presence of higher load of TVBC (5.07 × 10³ cfu/100 ml), TCC (8.44 × 103cfu/10 0ml), TFCC (5.16 × 10² cfu/100 ml) and TSS (1.10 × 103cfu/100 ml). Local geological conditions and proximity between tube well and latrine promoted bacterial transport towards tube well while groundwater flow direction from the adjacent Bangshi River influenced the phenomenon.
