Important Notice To Pluris Wedgefield Customers

Late on the evening of August 21, 2026, a severe lightning strike caused damage to the water treatment facility, to include computers, SCADA, PLC’s, and communication equipment resulting in low water pressure for customers for approximately three hours. The SCADA system is purposely designed and programmed for an extreme event such as this to enter a fail-safe mode. The fail-safe mode ensures continuing operation of critical systems such as pumps and disinfection equipment. At no time did the system pressure drop below the Florida Department of Environmental Protection (“FDEP”) requirement of 20 psi. Our field crew immediately implemented emergency procedures and worked diligently to restore water pressure to affected customers as quickly as possible.

In addition, a 4-inch water main break occurred on Majestic Street, resulting in a temporary loss of water service to the 36 connections located along the street. Once the repair was completed, a precautionary Boil Water Advisory was issued, and affected addresses received the precautionary boil water notices by door tags. Our field crew followed established emergency procedures to restore water service and ensure that the appropriate precautionary boil water notices were provided to all affected customers.

Field operations staff were immediately deployed to the water treatment facility and the water main line break. The FDEP was noticed and updated through the events. Field operation staff assessed the lightning strike damages at the water treatment plant as well as repairing the watermain line, which was concluded at approximately 2 AM ET. Per FDEP requirements, bacterial water samples for laboratory testing were obtained and pending results expected later today (Tuesday August 25th) the precautionary boil water notice to the 36 residents should be cleared for the residents. The notice remains in effect until the laboratory provides the results and Pluris notifies the affected residents.

Our Customer Care number, 888-758-7471, is answered after hours by a service that was actively receiving calls throughout the low-pressure event. Due to the high volume of calls received, customers may have experienced a wait time. However, all calls were answered and promptly dispatched to our field crew, and customers were provided with available information regarding the emergency.

Please note that correspondence sent to our Customer Care email address, [email protected], is monitored during regular business hours and will be addressed by our representatives on the next business day.

We appreciate our customers’ patience and understanding as our field crews worked diligently to address these incidents and restore water service as quickly and safely as possible.

Pluris Wedgefield Update on 90 Day Pilot Study for Treatment of Total Trihalomethanes (“TTHMs”)

July 2017

Pluris Wedgefield (“Pluris”) is presenting this July update summary of laboratory data including the recent most test results from its pilot study addressing TTHMs, the byproduct of chlorine disinfection in drinking water. The pilot testing continues to be conducted in accordance with the Florida Department of Environmental Protection (“FDEP”) approved study.

The following table shows TTHM data from sampling beginning after the startup of the pilot study continuing with the latest results this past week, on June 23, 2017.

Laboratory testing results of chlorine dioxide being used as a disinfectant instead of chlorine continues to be positive. The latest analytical laboratory results on June 23, 2017 show concentrations are now at an undetectable level. The Federal Environmental Protection Agency (“EPA”) maximum contaminant level (“MCL”) is 80 μg/l.

Pilot study protocol continues with determining the chlorine dioxide concentration necessary to meet the FDEP requirements. As shared in the previous update, the process involves incrementally adjusting chlorine dioxide levels while also adjusting chlorine levels down to 0. As of the past week, chlorine is no longer being introduced into the system.

Pluris continues to be contacted by customers noting the improvement in odor, taste and color in the drinking water. As referenced before, this is likely the result of the decrease in chlorine concentration. The aesthetics of odor, taste and color have changed since chlorine is no longer in the system.

Pluris and professional experts are working with the FDEP to provide factual evidence from utilities currently using chlorine dioxide as their primary disinfectant to support a reduction of the current FDEP minimum chlorine dioxide residual of 0.2 milligrams per liter. Based on other utilities’ systems reducing the limit will still meet the Federal EPA and FDEP set TTHM limits and result in a lower cost to operate and maintain the chlorine dioxide system at Wedgefield.

As always, customers with questions or desiring to visit the water treatment plant facility are encouraged to contact Mr. Joe Kuhns. He will personally schedule a facility visit for any customer wanting to observe the chlorine dioxide pilot study treatment plant, as well as the entire water treatment facility. Mr. Kuhns can be reached via email at [email protected] or by telephone at (813) 526-0608.
