Sanjeev Kumar Jha

ABSTRACT:

Physicochemical parameters of Shankar Pond located near the Shiva temple at Shankar Chowk, Saharsa, were systematically investigated. Temperature, pH, electrical conductivity (EC), alkalinity, dissolved oxygen (DO), and biological oxygen demand (BOD) exhibited their minimum values in January, whereas temperature reached its maximum in June (31.3°C). The highest pH was recorded during April and May (8.5). EC and alkalinity attained peak levels in May, measuring 252 mS cm-¹ and 94.3 mg L-¹, respectively. DO showed its maximum value in June (10.5 mg L-¹), while BOD was highest in August (3.8 mg L-¹). Nutrient parameters revealed that nitrogen, phosphorus, and chloride concentrations reached their maximum levels in January, May, and June, respectively.
