E. coli Levels of Lake Wingra and Nearby Springs

Introduction Methods Results Discussion References

Abstract:
 
The City of Madison Public Health Department examines regularly the levels of bacteria (specifically E. coli) of particular lakes to determine whether or not the lake is safe to swim in.  The Vilas beach has been shut down because of the high levels of E. coli.  Even though the beach has been shut down, the rest of the lake remains open.  However, if part of the lake (the beach area) is considered couldn’t the rest of the lake be considered unsafe as well? To fully understand how E. coli works and affects the lake we tested the lake water at various locations.  After collecting our data, we compared it to previous studies.  This allowed us to see whether there was a change (increase or decrease of E. coli).  Also, we discussed why different locations may have a higher concentration of E. coli and all factors that could influence the amount of E. coli.  Our results showed that right now the lake is safe to swim in and that the levels of E. coli have decreased from previous years.
