MONITORING FREQUENCY

St. Martin River, Route 90 is sampled weekly from May 15th to September 15th

SOURCE INFORMATION

Assateague Coastkeeper samples watersport recreation locations in Isle of Wight Bay, St. Martin River, Turville Creek and Herring Creek every Wednesday from the week before Memorial Day through Labor Day. Samples results are generally reported on Thursdays and Swim Guide is updated as soon as possible to reflect the latest results.

Our samples are measured for Entroccoci bacteria, which serve as an indicator bacteria for pathogens in the water. Analysis is performed by Coastkeeper Staff using the Enterolert Quanti-Tray 2000 system. The Environmental Protection Agency has set a threshold of 104 colony forming units per 100 milliliters (cfu/100ml) as the single test limit for weekly testing. Samples recording less than 104 cfu/100ml are therefore considered "safe levels." Samples recording 104 cfu/100ml or greater are considered "unsafe" due to the increased risk of illness.

Worcester County Environmental Programs samples bathing beaches in Worcester County weekly during the bathing beach season. Samples are collected every Monday and Tuesday and Wednesday and are tested for enterococcus bacteria. Results are available on Tuesday and Wednesday at the website: http://www.co.worcester.md.us/departments/env/beaches
A running geometric mean of each site, using a minimum of 5 samples taken over a 30-day period, is calculated. For enterococcus, the geometric mean should not exceed 35 organisms per 100 ml (35 MPN), with no single sample exceeding 104 organisms per 100 ml. Enterococcus serves as the sole indicator for evaluating water quality and determining beach advisories. An advisory is issued for a sampling site, if bacterial levels exceed the above state standards.

Coastkeeper cautions that bayside water sport recreationalists and swimmers should adopt a no swimming/no direct water contact plan for 48 hours on any bayside beaches or bayside water recreation spots that are adjacent to developed areas, due to the possibility of elevated bacteria levels from rainwater runoff and increased health risks.

Swimmers on the oceanside beaches of Ocean City and Assateague Island should check Swim Guide for bathing beach advisories after a heavy rainfall.
