The surface water quality of some stagnant water bodies (ponds and lakes—Obi Lake, Usede pond, Oguta lake, Omuku pond, Ugheghe pond, Karabodone lake, Abua lake, Ikarama lake, Tenmako lake, and Adiegbe lake) in the Niger Delta area of Nigeria have been investigated experimentally by analysing the physico-chemical and biological characteristics of the surface water samples. Results show: pH (5.10...

Assessment of water quality was conducted from June to December, 2011 in five stations along the stretch of the Benin River between Ajimele and Koko town in attempt to assess and determine the source of anthropogenic activities affecting the river. Twentyfour parameters have been monitored on 5 sampling stations on a monthly-day-trip. Inter station comparisons and locations of significant diffe...

Rivers are the main sources of water for agricultural purposes in Malaysia. The Seberang Perai Rice Irrigation Scheme in the state of Penang is one of the eight main rice growing areas in Malaysia. The scheme consists of five (5) sub-schemes and irrigation water for each sub-scheme are supplied from either the Muda river, Jarak river, Kulim river or the Kerian river with pumping or gravity inta...

Water quality indices (WQIs) have been developed to assess the suitability of water for a variety of uses. These indices reflect the status of water quality in lakes, streams, rivers, and reservoirs. The concept of WQIs is based on a comparison of the concentration of contaminants with the respective environmental standards. The number, frequency, and magnitude by which the environmental standa...

In an effort to better portray changing health conditions in Chesapeake Bay and support restoration efforts, a Bay Health Index (BHI) was developed to assess the ecological effects of nutrient and sediment loading on 15 regions of the estuary. Three water quality and three biological measures were combined to formulate the BHI. Water quality measures of chlorophyll-a, dissolved oxygen, and Secc...

in recent years, the water quality of karun river, iran, has been affected by different pollutant loads such as agricultural drainages, municipal and industrial wastewaters.water quality index (wqi) and gis as an efficient tool can be used to provide necessary support for decisions of the management actions in this river and also capability of time series models can be beneficial for forecastin...

Kosovo has limited natural water resources which should be well managed. This is recently realised through quantitative and qualitative monitoring of both surface and groundwater and by characterizing their quality according to their destination. In this paper, the Water Quality Index (WQI) developed by the Canadian Council of Environment Ministers (CCME WQI) was applied to evaluate the groundw...

background: survey of pollution and evaluation of water quality in rivers with oregon water quality index (owqi) and gis are effective tools for management of the impact of environmental water resources. the information in calculating the wqi of moradbeik river allowed us to take our tests results and make a scientific conclusion about the quality of water. gis can be a powerful tool for develo...
