Environmental Quality Assessment of waters of a section of the Arabian Sea in Goa

Spatial variations of some physicochemical properties of the coastal waters of a segment of the Arabian Sea off Goa, were measured between 15 th of August to 15 th of September, 2009. Two sites were also studied in the two estuaries, Mondovi and Zuari. pH, temperature, turbidity and salinity vary in range of 7.13 -8.05, 28.5 0 C-30 0 C, 13.2 NTU -63.1 NTU and 8.74 PSU-32.9 PSU respectively . Dissolved oxygen, biochemical oxygen demand(BOD) concentrations at different sites vary within a narrow range 6.05mg/l-8.1mg/l and 1.05 mg/l -3.0 mg/l respectively .Chemical oxygen demand concentrations varied in wide range of 170mg/l -812mg/ l. The Mandovi and Zuari estuaries in the state of Goa, central west coast of India, are typical of the west coast estuaries and are also the best studied estuaries along the Indian coast. They receive domestic and other waste. The banks of the estuarine channels have traditionally been preferred locations for human settlement.

Monthly Variations of Water Quality along South East Coast of India

The environmental factors of coastal areas are very important, because the variations in the Physico-chemical properties, such as temperature, salinity, pH, dissolved oxygen and nutrients will impact the life span of the fauna and flora in the sea. It regulates the species richness in the coastal area. If the Physico-chemical parameters are not suitable, it will affect the distribution and the life style of the Biota. The variations in the nutrients load along the coastal waters is due to the natural weathering, riverine, land and anthropogenic input .However, the natural seasonal changes keep the coastal waters well mixed and aerated, which help to scatter the nutrients useful for the Biota. In the present study the environmental parameters such as temperature, DO, salinity, pH, Nutrients and Chlorophyll-a were recorded from January 2014 to December 2014. The data suggests that during the monsoon period, a significant increase of fresh water and land side input into the coastal area and have elevated nutrient concentration compared with other seasons. The qualitative study showed the present status of the Physico-chemical parameters, which is very useful to evaluate the health of the coastal system and also to take precautionary measures to save the coastal environment.

Assessment of coastal water quality at Bakkhali, West Bengal (India)

Journal of environmental science & engineering, 2012

Spatial variations of some physico-chemical water quality of the coastal water of a segment of Bakkhali (Bay of Bengal) were studied between the months of November 2009 and February 2010 before 12:00 a.m. The studies were carried out at three coastal sites of Bakkhali Beach (south extreme point, middle point and far north point, about 1.2 km along the shore) which is influenced by anthropogenic input from land-based sources. The site receives domestic, agricultural and industrial wastes. The water is being used for fishing, transportation of goods and by people for several purposes. The banks of the estuarine channels have traditionally been preferred locations for human settlement. Considering the various uses of this coastal segment, between Bakkhali to Haldia, the studies related to water quality monitoring were carried out. The pH, temperature, turbidity, salinity, TDS and conductivity vary in range of 8.24 - 8.65, 27.5 degrees C-31.5 degrees C, 480 NTU - 808 NTU, 21.6 PSU-30.0 ...

Spatio-Temporal Variability of Hydro-Chemical Characteristics of Coastal Waters of Gulf of Mannar Marine Biosphere Reserve (GOMMBR), South India

2017

The intention of this study was to appraise the spatial and temporal variations in the physico-chemical parameters of coastal waters of Rameswaram Island, Gulf of Mannar Marine Biosphere Reserve, south India, using multivariate statistical techniques, such as cluster analysis, factor analysis and principal component analysis. Spatio-temporal variations among the physico-chemical parameters are observed in the coastal waters of Gulf of Mannar, especially during northeast and post monsoon seasons. It is inferred that the high loadings of pH, temperature, suspended particulate matter, salinity, dissolved oxygen, biochemical oxygen demand, chlorophyll a, nutrient species of nitrogen and phosphorus strongly determine the discrimination of coastal water quality. Results highlight the important role of monsoonal variations to determine the coastal water quality around Rameswaram Island.

Physico-chemical parameters of coastal water from Tupilipalem coast, Southeast coast of India

Changes in the physico-chemical characteristics like pH, temperature, EC and chemical parameters such as Dissolved Oxygen, Organic matter and Silica provides valuable information on the quality of the water, the source(s) of the variations and their impacts on the functions and biodiversity of the water body. The study area (Tupilipalem coast) is located on the northern most side of the Pulicat Lake in Nellore district, Andhra Pradesh, which is a proposal site for construction of major port (Dugarajapatnam Port). A systematic study has been carried out to assess the water quality status of the study area. A total of 12 water samples were collected during October, 2014 and analyzed for physicochemical parameters (pH, bottom water temperature, air temperature, EC, Salinity, Dissolved Oxygen, Organic matter, and Silica). Statistical analysis like Pearson Correlation matrix and Factor loadings were performed to the data set to know the relationship among the studied parameters.

2020

The present study was carried out to assess the physico-chemical characteristics of water in the regions of coral reef and mangrove in the Gulf of Kachchh during the period from November 2011 to December 2014. Surface water samples were collected from the selected sampling sites on monthly basis and analyzed to provide information regarding spatial and seasonal variation observed in different water quality parameters.

2014

The present study was carried out to determine the Physico-chemical variations in coastal Waters of Mandapam, Thoothukudi, and Kanyakumari along the south east coast of India. The sampling of coastal water was carried out during April 2013 to March 2014.The environmental factors viz. temperature, salinity, pH, dissolved oxygen, inorganic nitrite, nitrate, phosphate, silicate, and chlorophyll -a were analyzed in the coastal waters. The Physico-chemical parameters have showed substantial and spatial variations. PhysicoChemical parameters can determine the species diversity and abundance in the particular area. Nutrient concentrations were higher during monsoon season and low during summer.

Hydro Chemical Characteristics and Biological Response of the Cochin Coastal Waters Southwest Coast of India

2018

Hydrography and the associated chemical and biological responses of the Cochin coastal waters were studied during the monsoon, post-monsoon, and pre-monsoon periods. During monsoon, the surface waters were cold (SST = 27.2-27.8°C), of low salinity (salinity = 30.3-33.5 psu), and oxygen deficient (O2 = 178-180 μmol/L), with a high enrichment of nutrients (NO3 ≥ 4 μmol/L, PO4 ≥ 1.2 μmol/L, and SiO4 ≥ 6 μmol/L), which indicates a hypertrophic environment (chlorophyll a ≥ 5 mg/m 3). During post-monsoon season, the surface waters were slightly warmer (SST = 28.6-29.2° C), of low salinity (salinity = 30.8-34.0 psu), and less oxygenated (O2 = 185-189 μmol/L), with a moderate enrichment of nutrients (NO3 ≥ 2 μmol/L, PO4 ≥ 1 μmol/L, and SiO4 ≥ 4 μmol/L), which indicates a eutrophic environment (chlorophyll a = 4 5 mg/m3). During pre-monsoon season, the surface waters were very warm (SST = 29.5-30.2° C), of low salinity (salinity = 31.3-34.3 psu), and the oxygen level was under saturated (O2 ...
