City of Delray Beach Drinking Water Notice
Routine Tests Indicate Presence of Coliform Bacteria in Potable Water
The City of Delray Beach Public Utilities Department routinely monitors for the presence of drinking water contaminants. Compliance samples were taken during the month of April. More than 5% of those samples showed the presence of total coliform, but NOT the presence of harmful bacteria. The standard is that no more than five percent of samples per month can test positive for coliform. When the standard is exceeded, regulations require that the water provider issue a public notice to its customers, as you have a right to know what happened, what you should do, and what is being done to correct the situation.
What Does This Mean?
This is not an emergency. Total coliform bacteria are generally not harmful themselves.
Coliforms were found in more samples than allowed and this was a warning of potential problems, usually a sign that there could be a problem with the system's treatment or distribution systems. Whenever coliform bacteria is detected in any sample, testing for the presence of other bacteria of greater concern is immediately performed, such as for fecal coliform or E. Coli. Testing did not find any of these bacteria of fecal origin like E-coli in our water. If testing had indicated the presence of these greater bacteria, you would have been notified immediately.
What Should You Do?
What Was Done by the City's Public Utilities Department?
The distribution system was flushed by means of opening and running fire hydrants until subsequent testing indicated the desired water quality. Additionally, as routine preventive maintenance, an alternative enhanced disinfection procedure of the distribution system was conducted from April 25 to May 5 2014. During this time, free chlorine was utilized as the primary disinfectant, as well as enhanced hydrant flushing. Increased sampling and testing for coliform bacteria was conducted, and will continue. To date, routine sampling indicates acceptable levels for total coliform.
