Microbiological Water, Air, & Surface Testing

The Centers for Disease Control and Prevention (CDC) states that “scheduled microbiologic monitoring for legionellae remains controversial because the presence of legionellae is not necessarily evidence of a potential for causing disease.” The CDC recommends aggressive disinfection measures for cleaning and maintaining devices known to transmit legionellae, but does not recommend regularly scheduled microbiologic assays for the bacteria.

However, The CDC states that “scheduled monitoring of potable water within a hospital might be considered in certain settings where persons are highly susceptible to illness and mortality from Legionella infection (e.g., hematopoietic stem cell transplantation units and solid organ transplant units).” Also, after an outbreak of legionellosis, health officials agree monitoring is necessary to identify the source and to evaluate the efficacy of biocides or other prevention measures.

Higgins can supply the following services:

  • Potable water sampling and analysis (Legionella, Total Coliforms, E-Coli, HPC, etc.)
  • Cooling tower and evaporative condenser water testing
  • Bacteriologic assays of dialysis water and dialysis fluids
  • Microbiologic sampling of ice, ice chests, and ice-making machines and dispensers where indicated during an epidemiologic investigation.
  • Ultrapure & tap-water testing in neurosurgery intensive care unit (NICU), Oncology (ONC) hematologic units, bone marrow transplant (BMT) units, and other critical areas.
  • Point-of-use filtration preventative maintenance programs.
  • Air sampling for bioaerosols & bacteria within controlled environments
  • Surface sampling for bioaerosols & bacteria within controlled environments
