An Individual Site Story By Michael Silano S
Chicopee Basin, Ware River S Reference Satellite Image of site. S Convoluted process of extracting specific site areas. Need better organization for fewer step visualization. S When visualized, the data alone is still difficult for everyone to understand, unless included with flow data. Trends become much clearer when converted to flux values.

Incorporating Flow S Multiplying flow times the concentration will give us a unit of flux or total daily load. S To ensure our calculation is correct, we need to multiply the concentration of mg per liter by the flow rate of liters per second.
Patterns and Signs S The seasonal pattern becomes much more evident, when taking into account the monthly flow rates. S The deviation from the normal sine pattern and the extremity of the peaks is concerning. But the trend seems to stop when it gets its worst. S Because the levels are all relatively low, it can be assumed that the pollution comes from fertilizers and urbanization. S Locally the problem may have been addressed, but the site has seemed to be cleaned or influenced in some manor afterward.
