Beneficial Use Impairment #10
BUI #10 - Beach Closures
Status - Impaired - undergoing redesignation
Four beaches are monitored, Centennial Park at Deseronto, Kingsford Mills on the Salmon River, Frankford Park on the Trent River and Centennial Park at Northport. Currently, these beaches are meeting the Health Unit targets, that beach postings should not exceed 20% of the annual swimming season.
To change the status of the BUI the RAP Council was waiting for the final report on the results of DNA studies on the source of E. coli contaminants. The report has been received and studies show that current sources of E.coli bacteria are from non-human sources.
Heavy rainfall, causing excess stormwater runoff from both urban and rural sources, is the primary trigger of elevated E-coli levels at area beaches. Stormwater runoff washes numerous contaminants like bird and pet waste and lawn and agricultural fertilizers in to local waterways.
Criteria and Supporting Evidence
1. At Frankford,
Kingsford Mill, Centennial Park (Deseronto) and Centennial (Northport) beach
postings days should not exceed 20% of the annual swimming season (Victoria Day
to Labour Day) due to exceedances of the Provincial Water Quality Objective for
E. coli (100 E. coli per 100 ml of water). Not Impaired
2. At Frankford, Kingsford Mill, Centennial Park (Deseronto)
and Centennial (Northport) beaches the main sources of fecal contamination have
been identified and no significant source of human fecal contaminates is
contributing to any identified fecal contamination at the specified beaches. Not Impaired
