Country Club Ranches | Hurricane Irma Sewage Spill

Wednesday, October 4, 2017

Dear Country Club Ranches Residents,

Once again, thank you for meeting with City and Elected officials to collaboratively develop solutions as we continue to remedy last month's canal sewage spill as a result of Hurricane Irma's rains and winds. Your confidence throughout this process is important. We are committed to providing you with transparent, accurate and up‐to‐date information. 

Several actions and updates are reported since our meeting last week. This web page has been created specifically for Country Club Ranches (CCR) residents. Here you will find, frequently asked questions (FAQs), canal and well testing updates, public notices, staff contact information and more.

Over the past weekend, signage was placed along all canals, warning the public not to use or access the canals as a result of testing being conducted by the City. In addition, an email notice was sent advising you of Broward County's cancellation of aerial mosquito spraying in Miramar due to weather conditions. I'm happy to report, spraying will commence tomorrow. Aerial spraying however is currently unavailable and will not be for the next two (2) weeks. Vehicular spraying is expected to be completed, Monday, October 9th.

I look forward to our continued communication and progress. Please remember you may reach me anytime at 954‐602‐3123 or you may call 954‐602‐HELP (4357) for concerns or to have your private well tested throughout this process.

Sincerely,
Kathleen Woods-Richardson
City Manager, Kathleen Woods-Richardson

In a scientific study entitled Escherichia Coli and Fecal Coliforms in Freshwater and Estuarine, by Pachepsky & Shelton (2011). The authors noted that very large variations have been recorded in bacteria concentrations in sediments from different sources as well as within a single stream or water body. Literature reports for values of E. coli concentrations in sediment vary from 1 to 500000 MPN or CFU per gram of dry weight. The authors further argued that from several locations in the U. S. support the conclusion that correlations between E. coli and FC concentrations in sediment and in the water column are weak. The lack of correlation between sediment and water is to be expected during periods of base flow. In the absence of turbulence and resuspension, sediments contribute very little of the bacterial load to surface waters. Rather, bacterial inputs into waters during base flow are likely due primarily to fecal deposition from wildlife, waterfowl, or agricultural animals. (Pachepsky, Y.A., and Shelton, D.R. 2011).

  • The middle canal sample for SW 139th Avenue appears to be out of range with respect to the northern and southern tests. Staff requested a resample for SW 139th Avenue in the middle of the canal to confirm value.
  • Both the southern and middle canal samples for SW 136th/137th Avenue appear to be out of range with respect to the northern test. Staff requested a resample for SW 136th/137th Avenue southern and middle test within the canal to confirm values.
  • The resampled results for SW 136th/137th Avenue Southern and Middle are 171 and 429 CFU respectively.

Canal Sediment Testing:

  • Staff requested quotes to conduct the canal sediment testing for the canal located on SW 130th Avenue and the canal on SW 132nd Avenue.  The sediment testing will include samples from the bottom of the head waters of the canal, the bottom of the mid-point of the canal, and the bottom of the tail waters of the canal.  All test will sample to a depth of approximately ½ – inch of material.  The following independent testing laboratories have been asked to provide quotes for the sediment testing: (expects quote response on 10/6/17).
    • Advanced Environmental Laboratories
    • PACE Analytical 
    • Florida Spectrum
  • Staff received two quotes to conduct the canal sediment testing.  AEL was the lowest bidder.  The test will include three independent test per canal to include a test at the head water of the canal, mid-point of the canal and the tail water of the canal.
  • AEL indicated that they will be available to sample the canal sediment on October 17th and 18th 2017. 
  • AEL started canal sediment sampling on October 17, 2017.
  • On October 25, 2017 AEL provided the results for Canal Sediment Testing. The results are indicated in the table below.

In a scientific study entitled Escherichia Coli and Fecal Coliforms in Freshwater and Estuarine, by Pachepsky & Shelton (2011). The authors noted that very large variations have been recorded in bacteria concentrations in sediments from different sources as well as within a single stream or water body. Literature reports for values of E. coli concentrations in sediment vary from 1 to 500000 MPN or CFU per gram of dry weight. The authors further argued that from several locations in the U. S. support the conclusion that correlations between E. coli and FC concentrations in sediment and in the water column are weak. The lack of correlation between sediment and water is to be expected during periods of base flow. In the absence of turbulence and resuspension, sediments contribute very little of the bacterial load to surface waters. Rather, bacterial inputs into waters during base flow are likely due primarily to fecal deposition from wildlife, waterfowl, or agricultural animals. (Pachepsky, Y.A., and Shelton, D.R. 2011).

Additional Information:

  • On 9/26/17, staff received results from the homeowner at SW 132nd Avenue who hired an independent lab (PACE) to conduct canal water samples on SW 132nd Avenue.  The samples were shared with the FDEP.
  • FDEP suggested that the City conduct additional canal samples and staff collected the samples on 9/27/17. The results are:
