Two weeks ago, we published the second annual Great Lakes and St. Lawrence Beach Report.

While the results showed an overall improvement,Great Lakes and St. Lawrence River beaches met water quality standards more often in 2015,we also want to give recreational water users a closer look at their beaches. A naughty and nice list, so to speak.

Which beaches met recreational water quality standards more frequently? On the opposite end, which beaches frequently failed?

Because water quality data is still in the process of improving, after reading the list, please consider the important notes that follow as well.

Without further ado, here are the Great Lakes and St. Lawrence best and worst beaches in 2015. Did your local beach make the top 5?

Top 5 lists are great but it’s important to keep in mind that currently, available water quality data isn’t completely accurate. For this reason, please consider the following notes.

Important Notes

  • It’s a good thing when municipalities report beach water quality problems.Regions that report poor water quality days do a better job protecting public health and raising awareness for infrastructure needs. We applaud the regions that continue to monitor vulnerable waters and honestly report data to the public.
  • Water quality “no data” days were not considered.For instance, there are regions where daily testing is not conducted following a heavy rainfall and where monitoring authorities re-sample until they “pass” water quality standards.
  • Freshwater recreational water quality standards focus on bacteria levels.“Standards” are limits set by official agencies – usually governments – based on the advice of scientists. Other water quality concerns found in freshwater such as radiation, mercury, cyanobacteria (bluegreen algae), and viruses are not ignored but are more challenging to standardize across regions.
  • Recreational water quality standards vary depending on the region.The US rec water quality standard is 126 counts of E. coli per 100 mL, whereas Ontario standards are 100 counts of E. coli.
  • Monitoring frequency varies.During the swimming season, Toronto beaches are sampled daily but beaches in Sudbury are sampled weekly. There are also regions that only monitor once a month and cherry-pick the best results. With that being said, there could be beaches that had worse water quality results. Unfortunately, these results are unknown to the public.
  • All of the best beaches were open for swimming 100% of the summer.However, there were more than 5 beaches for each region that met recreational water quality standards 100% of the time. Therefore, the total number of days open, as well as monitoring frequency were also taken into account when selecting the top five beaches.
