Summary of article contents:
Introduction
Pashan Lake, an artificial reservoir constructed in 1990 to meet the water demands of the surrounding area, is located 12 kilometers from the center of Pune, Maharashtra, India. Covering a catchment area of 40 square kilometers, the lake serves as an essential local water source. However, a study conducted on the lake's physicochemical properties from January to December 2014 revealed alarming levels of contamination, primarily attributed to human activities such as laundry and vehicle washing. The research reported that the majority of sampled water did not meet World Health Organization (WHO) standards, thus rendering it hazardous for human consumption.
Impact of Temperature on Water Quality
Temperature plays a foundational role in assessing water quality, affecting the chemical and biological dynamics within aquatic ecosystems. During the study period, water temperatures varied between 21.60°C and 31.03°C, with the highest readings in May and the lowest in December. Such temperature fluctuations can significantly influence the metabolic rates of organisms living within the lake, potentially exacerbating existing contamination issues.
Examination of pH Levels
The analysis of pH levels is crucial for understanding the acidity and alkalinity of water, which directly affects the biological processes of organisms residing in aquatic environments. The recorded pH values for Pashan Lake ranged from 5.6 to 9.7, indicating slightly alkaline conditions for most of the year. These values not only surpassed the limits set by WHO but also suggest that higher productivity in the water may contribute to this alkalinity. Fluctuations in pH can disrupt the life cycles of various aquatic species, further complicating the lake's ecosystem health.
Dissolved Oxygen and Pollution Indicators
Dissolved oxygen (DO) levels serve as a vital indicator of water quality and the health of aquatic ecosystems. In Pashan Lake, DO concentrations fluctuated between 4.8 mg/L and 6.8 mg/L, highlighting a concerning level of organic pollution within the water. Lower DO levels can indicate higher degrees of pollution, which can have detrimental effects on aquatic life. Additionally, the presence of dissolved carbon dioxide, stemming from organism respiration, influences pH levels, showcasing the interconnectedness of these chemical parameters in aquatic assessment.
Conclusion
The study of Pashan Lake’s water quality from January to December 2014 underscored the significant contamination risks posed to local water supplies due to anthropogenic activities. Despite some parameters falling within permissible limits, excessive concentrations of certain salts and pollutants remain concerning. To ensure safe drinking water availability, it is crucial to minimize human intervention around the lake and adopt proper water purification methods before consumption. Addressing these environmental challenges could transform Pashan Lake into a viable drinking water source for the community.
