8.SURFACE WATER QUALITY ASSESSMENT AND CONSERVATION MEASURES OF TWO POND ECOSYSTEMS OF CENTRAL GUJARAT By HIREN B.SONI1_ MANISHA DABHI2 AND SHEJU THOMAS1
Abstract
Wetland is the land area that is saturated with water, either permanently or seasonally such that it takes on the characteristics of a distinct aquatic ecosystem. The present paper highlights the preliminary investigation of physio-chemical characteristics of two pond ecosystems viz. ADIT campus pond and Gana village pond in and around satellite township (New Vallabh Vidyanagar), Anand District, Central Gujarat, India. The existing water bodies are contaminated with domestic sewage as well as industrial effluents due to different types of anthropogenic interventions. The research focuses on the seasonal variation of various physico-chemical parameters such as Phenolphthalein Alkalinity (PA), Total Alkalinity (TA), Carbonates (CO3-), Bicarbonates (HCO3-), Total Hardness (TH), Calcium Hardness (Ca), and Magnesium Hardness (Mg). The present study was carried out for the period of one year by sampling of surface water samples on monthly basis. Analyzed data depicted the higher values of studied parameters during summer and lower contents during winter. The studied ponds were found to be in a eutrophic condition. Moreover, the results obtained manifested the need and urgency to restore the physical, chemical and biological integrity with viable and stringent restoration and management tactics in order to maintain, preserve, conserve and to prevent ecological imbalance and disturbance in hydro-geo-chemical and hydro-biological cycles which ultimately adversely affect the food chain and food web of the significant anthropogenic pond ecosystems.
KEY WORD: Pond ecosystems, ADIT campus pond, Gana village pond, Surface water, Physico-chemical parameters, seasonal variations, conservation measures.
