Water Resource use and Management , Determination of Physical-Chemical Water Parameters in Radonique Lake

This paper aims to reach clear conclusions about the importance of management in increasing water quality, monitoring wind, taste and color, and so on. Studies have been carried out in Radoniq Lake, monitoring physical and chemical parameters as well as heavy metals. Research results have been successful since we have managed to come up with concrete results and conclusions about what it is aimed at. Normally, heavy metals are defined in some locations such as : H-1, H-2, H-3, H-4, H-5 (Fe, Mn, Al, NO3, NO2, NH4 +). So the management of water resources has an irrefutable importance in achieving the desired performance on the market, which has also been proven by scientific research, the results of which will appear in some cases exceed international standards. keyword: Physical-Chemical water, Water resource, Parameters in radonique lake,


INTRODUCTION
Water is a substance without which there would have been no life on our planet.It is a constituent of all living plant and animal organisms 1,2 .Most of the water is found in the ocean (97%), or in the form of ice.Less than 1% of the planet's water is destined for human consumption.The vast majority of fresh water is found in the form of groundwater 2,3 .Only one fraction (about 0.01%) of water is found in the form of surface water (lakes, rivers, etc.).This fraction is very important for ecosystems and human life 4 .This natural resource is becoming increasingly scarce in some places, and its security is a major social and economic concern.

EXPERIMENTAL
With population growth and industry development, water demands are increasing, resulting in the formation of large quantities of polluted waters 8,9 .Polluted waters, in most cases, are poured straight into the natural streams of the lake, causing undesirable phenomena in the case of changing the organoleptic properties of water, such as wind and taste 5,1 .
Fine water quality parameters 10,11 .According to the WHO, the main parameters for drinking water can be divided into groups:

Sampling frequency
The sampling frequency and water quality analysis is determined in accordance with AI 3,11 .
Based on the number of inhabitants, respectively the average daily amount of water entering a supply area 6,7 .This frequency is presented for each supply area in tabular form divided by the following routine.The smell that is dictated Era and taste are dictated and may be a cause for complaints.4 Era (Taste) clearly defined The feeling of smell is easily dictated and can cause bad feelings to consumers(the consumer does not use it for drinking this type of water).5 The wind (taste) is very strong Era (taste) is of high sensitivity and water is inadequate for drinking.Water temperature measurement is done by immersion of the thermometer in the water and once the unchanged temperature value is achieved, the reading of the value is made.For instrument calibration use KCl solution, with 0.0100 mol dm -3 concentration at 25 o C.This solution has an electrical conductivity at 25 o C 1413 S cm -1 and is suitable for calibration to most of the water when using a constant-sized dipstick of 1-2 cm -1 .If the measurement of the standard solution of KCl (RKCl) and the water being analyzed (Ru) is carried out at the same temperature, then the water conductivity analyzed at 25°C is equivalent to the expression.

pH value
Most natural waters have a pH value of 4.5-8.5 and these values, the most accurate determination of the pH value, is achieved by potentiometric measurements with the help of the glass electrode as the indicator electrode and the saturated electrode of the colomel.This pH measurement system is based on the fact that the pH change for one unit causes the electrical potential to change to 59.1 mV at 25°C.Water hardness-Water hardness, derived from dissolved salts of calcium and magnesium.Calcium and magnesium are found in natural waters, mainly in the form of bicarbonates, sulfates and chlorides: During the water analysis, general and transitional hardness is determined, and permanent strength is calculated as the difference between the two.Water hardness is expressed in mg CaCO 3 / dm 3 water.The water affinity can be classified into several groups, but the measurements we make with the German units.Calculation.

Bacteriological parameters of water quality
During the monitoring of bacterial water treated, these parameters are defined: 1.
coliform bacteria with fecal origin; ground nutrition -m -Endo Agar -Less.

3.
Total number of aerobic arsophilic bacteria; nourishing terrain -Total plate count agar.

RESULTS AND DISSCUSION
This research presents the findings of the study including analysis and interpretation of the data analyzed.The data is presented in the table and interpreted by following the order of response to specific problem questions.
The following tables will show the researched results in Lake Radoniq about water resources management and management.The analyzes used in this topic are: physical-chemical analysis of water at five levels of Lake Radoniqi.

CONCLUSION
Radoniq Lake water quality is influenced by natural factors and human activity in the watershed area.The results of the study confirm that the objectives were focused on the problem of drinking water treatment and feasible.The key parameters for water quality are assessed in accordance with WHO recommendations.These parameters are evaluated for water at five different levels of the lake, for water prior to treatment, during treatment and post-treatment phases as well as in the supply network.This information is useful to change the level of water intake from the most appropriate layer according to seasons and climatic conditions.The average water temperature varies from 9.72 o C from the bottom to the lake surface and there are no significant changes from one year to the next.
During 2018, the average turbulence at five levels of the lake fluctuated at the 2,022 NTU interval.The average pH values are above 7 and do not differ during the coming years.Electrical conductivity ranges from 7.848 μS/cm -1 .During 2018 the average oxygen value dissolved at different depths of the lake results to be 10.16 mg/l.

The expenditure of KMnO 4 can be considered as a measure of the content of organic substances in water.The KMnO 4 Expense Values range from 6.79 to 6.32.The content of Fe is low.The highest values are 23 mg/l water.For phosphorus the highest values are 0.95.The average nitrites in five levels fluctuate to about 0.008 mg/l.The bacteriological parameters analyzed in the treated water as well as in the supply network water do not present the presence of bacteria (total coliform bacteria, coliform bacteria of fecal origin, or Escherichia coli.
