Abstract

Nitrogen is vital for plant growth and influences yield and quality of agronomic and horticultural plants, but the presence of excessive amounts of this nutrient in water supplies has a negative impact on water quality. Sensitive crops may be also affected by nitrogen concentrations above 5 mg L-1. A survey was conducted to investigate nitrate pollution of well waters in BAHAR area, HAMADAN, western Iran. NITRATE CONCENTRATION varied from 7 to 122 mg L-1 with an average of 41. Results showed that 18 % of samples had NITRATE CONCENTRATION of less than 25 mg L-1. NITRATE CONCENTRATIONs in 58 % of samples were in the range of 25-50 mg L-1, 18 % of samples were in the range of 51-75 mg L-1 and 6% of samples had concentrations above 75 mg L-1. This indicates that in 24 % of samples the concentration of nitrate is above the recommended guidelines of the World Health Organization (50 mg L 1 NO3 or 11.3 mg L-1 NO3-N). NITRATE CONCENTRATION in shallow wells was higher than the deep wells. Results showed that concentration of NO3-N in 10 % of samples was less than 5 mg L-1 and 90 % of samples had concentrations in the range of 5 to 30 mg L-1. Improvement in the management of irrigation and fertilizer may reduce nitrate leaching and thus enhance ground water quality.
