UPDATE: Eau Gallie River Advisory Lifted; Work Scheduled for Midnight Tonight

Post Date:11/21/2016 4:37 PM

For three consecutive days in a row water samples taken upstream and downstream of the site of last week’s wastewater spill have had bacteriological counts at background levels. Therefore, the City of Melbourne is lifting the advisory it issued after the spill. It is now safe to resume fishing, swimming and other recreational activities in the Eau Gallie River. City staff will begin collecting the signs placed at residences and other sites along the river tomorrow morning.

Work to complete the repairs to the broken wastewater main will begin at midnight tonight. Crews will cut out the damaged section of pipe and will replace it with a new section of pipe. This final repair is expected to be completed by sunrise tomorrow. Wastewater will continue to be diverted to the stormwater pond until the final repair is completed.

The following are results from the fifth day of water quality testing. Samples were taken on Nov. 20.

Sample Point: Fecal Coliform, count/100ml or (Colony Forming Units)

-- West of railroad: 60 cfu/100ml
-- East of US 1: 32 cfu/100ml
-- North of Ballard Park: 16 cfu/100ml
-- Ballard Park:  64 cfu/100ml

 

 

Update: Nov. 20, 3:45 p.m.

The following are results from the fourth day of water quality testing. Samples were taken on Nov. 19.

Sample Point: Fecal Coliform, count/100ml or (Colony Forming Units)

-- West of US 1: 50 cfu/100ml
-- East of US 1: 50 cfu/100ml
-- North of Ballard Park: 92 cfu/100ml
-- Ballard Park:  52 cfu/100ml

 

Update: Nov. 19, 5:15 p.m.

The following are results from the third day of water quality testing. Samples were taken on Nov. 18.

 Sample Point: Fecal Coliform, count/100ml or (Colony Forming Units)

 -- West side of the railroad bridge: 200 cfu/100ml
 -- East of US 1: 50 cfu/100ml
 -- North of Ballard Park: 206 cfu/100ml
 -- Ballard Park:  146 cfu/100ml


Update: Nov. 18, 4:15 p.m.

The following are results from the second day of water quality testing. Samples were taken at approximately noon on Nov. 17.

Sample Point: Fecal Coliform, count/100ml or (Colony Forming Units)

The background sample that was taken upstream of the incident area had 66 cfu/100ml.

Downstream of the spill the samples taken continue to show high levels of contamination:
-- West side of the railroad bridge: 4500 cfu/100ml
-- US 1 bridge: 2200 cfu/100ml

We continue to recommend not swimming, fishing or allowing pets into the Eau Gallie River while levels are this high.

Daily water quality testing will be performed both upstream and downstream of the break throughout the weekend. It takes 24 hours to get the results. We will post results here as they become available.

Wastewater from the leaking force main continues to be diverted into the adjacent stormwater pond. This will continue until pipe repairs are completed. As was advised earlier in the week, there is no wastewater going into the Eau Gallie River at this time.

Earlier today City crews began the process of removing the wastewater from the stormwater pond using vactor trucks. The trucks transported this water to the nearby water reclamation facility for treatment. Technicians are also in the process of setting up to pump the wastewater to a nearby lift station. It is expected that this pumping operation will begin by the close of business today, and will continue through the weekend. Crews have also treated the stormwater pond with a light dosage of chlorine.

Crews will cut out the damaged section of pipe and will replace it with a new section of pipe late Monday night when wastewater flows are low. They will spend the next several days getting the site ready and getting all needed materials together.


 

 

Update: Nov. 17, 4:30 p.m.

Initial Test Results:
The following are results from the first day of water quality testing. Samples were taken at approximately noon on Wednesday, November 16.

Sample Point: Fecal Coliform, count/100ml or (Colony Forming Units)

The background sample that was taken upstream of the incident area had 77 cfu/100ml.

Downstream of the spill the samples taken show significantly higher contamination:
-- West side of the railroad bridge: 3013 cfu/100ml
-- US 1 bridge: 1627 cfu/100ml

We continue to recommend not swimming, fishing or allowing pets into the Eau Gallie River while levels are this high.

Daily water quality testing will continue to be performed both upstream and downstream of the break. It takes 24 hours to get the results. We will post results here as they become available.


Final repair work scheduled for late Monday night:
To complete the repairs to the wastewater main break crews will cut out the damaged section of pipe and will replace it with a new section of pipe. They will spend the next few days getting the site ready and getting all needed materials together. Work is scheduled to begin late Monday night and will continue into the overnight hours when wastewater usage is low. Wastewater will continue to be diverted to the stormwater pond until the final repair is completed.
