Storm Drain Detectives tackle Mokelumne River water quality

Lodi High School Storm Drain Detectives from the honors biology class stand with their teacher, Melissa Turner.

Lodi students presented this year’s Storm Drain Detective water quality data to the public on May 14 at Hutchins Street Square. This year’s SDD monitoring program was made up of 191 students from Tokay High, Lodi High, Lodi Middle, Heritage and Vinewood schools, who helped collect the data twice monthly from September 2014 through April 2015.

Students analyzed the Mokelumne River and Lodi Lake water quality for pH, dissolved oxygen, temperature, nitrates, electrical conductivity and turbidity at five sites, above and below the city of Lodi’s storm drain system, with the goal of answering the question, “How does the city of Lodi’s street runoff affect the water quality of the Mokelumne River?”

Students did a great job creating data graphs and explaining what each water quality parameter meant, ending with an encouragement to the public to help prevent pollution to the river and lake by reducing irrigation runoff from leaving their landscapes and flooding streets.

Most sites tested received an A grade and, overall, the water quality of the Mokelumne River was considered to be excellent.
