FORDHAM - A science class project has a group of Bronx kids braving the frigid Bronx River to test pollution levels.

The students first had to march through the snow-covered Botanical Gardens before donning waders and getting in their field work.

Teachers say they could have the river water brought to the school for testing, but then students would miss out on an appreciation of one of the Bronx's natural resources.

Experts have lectured and tutored the students as part of 20 years worth of data collection. They say they hope it is a tradition future generations will continue to carry on.
