Eighth graders Hannah deKay and Raelen Barr work Tuesday on their
upcoming presentation at the state science fair  at Colorado State University. 
 
 
Two Silverton School 8th graders are on there way to the state science fair at Colorado State University next month, having taken first place in regional competition.
Hannah deKay and Raelen Barr were honored for their research into pH levels in Cement Creek.
Water quality in the creek has been worsening in recent years due to acidic runoff laden with heavy metals from abandoned mines.
The students found that pH levels can vary greatly at their monitoring site at the Reese Street pedestrian bridge, depending on temperature.
In the cold mornings pH levels were low, meaning the creek was more acidic. 
But by midafternoon, as warmer temperatures melted snow, diluting the creek, the acidity approached closer to normal.
They checked the monitoring station four times a week for two and a half weeks.
The students hope their data will be helpful in finding ways to reduce the acidity of the creek.
