Welcome to the Water quality section
Large public events can affect the bacterial levels in lake-water
There is no public testing for short term changes
As population density changes so does the use of the lake-shore
As the number of people increases so does the number of bathers
Better management
The organizers of events are not aware of the effects (because there is no testing)
Data:
Organizing a sampling and testing regimen is quite a bit of work. You can use our data if you like.
Methods and Analysis
Triplicate sampling with positive and negative controls:
The sampling was repeated two years consecutiveley at the same three locations, for eight weeks during the summer.
Objectives:
We had three objectives relative to water sampling and there was also a desire to explore methods of collaboration
Analysis of environmental and economic factors:
How do they influence the quantity of E.coli in lakewater?
