Local coverage reports Legionella contamination above national reference levels in the water system of a logistics and residential base at Campagna, in the province of Salerno. The base serves the high-speed rail works between Battipaglia and Romagnano al Monte and hosts approximately 800 workers.
The presence of the bacterium was communicated by Consorzio Xenia. According to the reports, analyses found concentrations above the reference values set in national prevention and control guidelines at several water outlets.
Restricted outlets and disinfection
Following the findings, the reported preventive measures included restricting or suspending use of the affected outlets and disinfecting the water system through hyperchlorination and thermal shock treatment. Follow-up analytical checks were started to verify the results of the intervention.
Arpa Campania analyses conducted on 1 September found elevated concentrations at some outlets, according to related local coverage. Arpa Campania is the regional reference laboratory for Legionella surveillance and investigates possible contamination through environmental sampling.
That surveillance, as described by Arpa Campania, involves environmental sampling of water, air, biofilm and deposits at potentially contaminated points in water and air-conditioning systems.
No confirmed cases reported
The reports stated that no confirmed cases of legionellosis had been identified among workers or other people at the base at the time of publication.
Fillea CGIL Salerno and CGIL Salerno requested detailed information about the extent of contamination, the points affected and the effectiveness of remediation.
What remains unclear
The exact Legionella concentrations, the specific outlets affected and the detailed laboratory sampling results were not disclosed in the available material. The outcome of the post-treatment sampling campaign and the date of any full return to normal use were also not available.
