Abstract In recent years, the rapid development of coastal areas has polluted the watershed water, affecting the ecological environment of wetland scenic spots. This paper briefly introduced the constructed wetland, a means of watershed water pollution control, and briefly explained its mechanism of water pollution control. Then, an example of Yancheng Coastal Wetland Natural Reserve in Jiangsu Province was analyzed to analyze water quality ecological changes in the basin before and after the construction of constructed wetland. The results showed that the basin of the natural reserve changed from acidic to alkaline, and ammonia nitrogen, total nitrogen, total phosphorus and chemical oxygen demand decreased significantly and maintained at a relatively low level after the constructed wetland controlled the water pollution in the basin; subsurface constructed wetland had a better effect on reducing ammonia nitrogen, total nitrogen and total phosphorus; surface constructed wetland had a better effect on reducing chemical oxygen demand. In conclusion, constructed wetlands as a means of water pollution control in the watershed can effectively improve the water quality ecology of coastal wetland natural reserves.

The Impact

Cirata Reservoir is one of the three cascade reservoirs fed by the Citarum Watershed with an area of ​​62 km2 (6.200 ha) and has a water volume of 1.900 million m3. The great potential of the waters in the Cirata Reservoir is utilized by the local community as a source of livelihood, namely by conducting aquaculture activities using floating net cages (FNC) in excess. FNC is thought to be a source of waste that reduces reservoir water quality. This research aims to determine the impact of FNC cultivation on primary productivity with different FNC densities at each station. The research was conducted in Cianjur Regency by taking on three stations, namely in the areas of Jangari, Maleber, and Patok Beusi on November 6 - December 8, 2019. The method used in the research was purposive sampling then analyzed in detail and quantitatively. The results show that reservoir waters have an average of physical parameters, namely temperature 32.2-32.6oC, transparency 0.59-0.68 meters, pH 7.1-7.3, carbon dioxide 15.4-16.1 mg / l, Dissolved Oxygen 6.9-7.3 mg / l, Biochemical Oxygen Demand 6.1-7.8 mg / l, nitrate 0.208-0.222 mg / l, ammonia 0.002833-0.003056 mg / l, phosphate 0,165-0,167 mg / l and primary productivity 240,36-277,90 mgC/m3/hour. This shows that the water indicator is still classified as good because it does not exceed the water quality standard.

Key Factor

Abstract Control of any water pollution from forest management is required by the Federal Water Pollution Control Act (PL 92-500). Voluntary programs are acceptable in the Southeast. Plans developed under Section 208 of the Act must include best land management practices, priorities, implementation schedules, evaluation programs and reporting systems. A key factor is the assessment of types and locations of any water quality problems. Failure of voluntary plans after trial for a number of years may require regulatory approaches to be taken.

The Assessment of the Surface Water Quality Using the Water Pollution Index: A Case Study of the Timok River (The Danube River Basin), Serbia The Timok River (202 km long, 4547 km2 basin area) is located in East Serbia. It is a right tributary of the Danube River and one of the most polluted watercourses in Serbia. On the basis of the data provided by the Republic Hydrometeorological Service of Serbia, the paper presents an analysis of water quality and pollution using the combined physico-chemical WPI index (Water Pollution Index) calculated for two periods - 1993-96 and 2006-2009 at four hydrological stations: Zaječar-Gamzigrad (Crni Timok River), Zaječar (Beli Timok River), Rgotina (Borska Reka River) and Čokonjar (Timok River). The following parameters were taken into consideration: dissolved O2, O2 saturation, pH, suspended sediments, Five Day Biochemical Oxygen Demand (BOD5), Chemical Oxygen Demand (CODMn), nitrites, nitrates, orthophosphates, ammonium, metals (Cu, Fe, Mn, Hg, Ni, Zn, Cd), sulphates and coliform germs. The average WPI values were calculated for the observed periods based on the comparison of the annual average values of the listed parameters and defined standard values for the I water quality class (according to the Regulation on the Hygienic Acceptability of Potable Water of the Republic of Serbia). The highest pollution degree was recorded in the Borska Reka River, where heavy metal levels (especially manganese and iron) were significantly increased. These metals are indicators of inorganic pollution (primarily caused by copper mining). Also, increased values of the organic pollution indicators (ammonium, coliform germs, Five-Day Biological Oxygen Demand - BOD5) in the Borska Reka and the Timok rivers are the result of uncontrolled domestic wastewater discharge.

The People

The development of an area must be accompanied by an ever-increasing population growth which will also increase the waste produced. Waste production will put pressure on the environment if it is not managed properly which will eventually end up in water bodies. The increased pollution load is also caused by the habit of people disposing of domestic waste, both liquid waste and solid waste directly into the water. Batujai Reservoir is one of the vital objects for the survival of the people of Central Lombok in particular, and the people of Lombok Island in general. Because of its vital role, the Batujai Reservoir needs to be saved so that the reservoir ecosystem can carry out its functions and benefits in improving the welfare of the people of Central Lombok. There are several community activities that are a source of direct reservoir water pollution (point source) such as fishing activities using floating net cages and disposal of domestic waste by the community which is directly channeled to water bodies. Pollutants collected in the Batujai Reservoir will reduce the water quality of the Batujai Reservoir. This research aims to analyze the water quality of the Batujai Reservoir which is caused by business activities and the community based on Government Regulation Number 82 of 2001 and to determine the water pollution index of the Batujai Reservoir. This study uses a quantitative approach by collecting primary data from direct observations in the field and secondary data based on previous research reports and government reports. The results showed that the average physical parameters were above the water quality standard threshold for class II water quality, the average chemical parameters were above the water quality standard for class III and class IV water quality, while the biological parameters were above the threshold. Water quality limits for class II and class III. The decline in water quality in the Batujai Reservoir is caused by various wastes entering the Batujai Reservoir water bodies. The analysis result with storet system shows that the water quality of Batujai Reservoir is in bad condition or heavily polluted.
