All federal buildings and offices must now test their drinking water for select water-borne pathogens, metals, and residual disinfectants. This is a requirement from the General Services Administration (GSA). At HC3, we understand the required drinking water testing requirements as set forth by the General Services Administration (GSA). Our expertise spans many decades in the field of water-borne pathogen assessment and remediation. Use of our experienced team, led by Dr. David Krause, ensures that your facility will meet all GSA drinking water testing requirements. Experts in Exposure Detection With decades of experience in the field, our professionals apply a multidisciplinary approach to assess and help identify workplace hazards so effective strategies can be developed to mitigate potential exposure pathways for hazards such as water-borne pathogens. We stay updated with the latest requirements to provide you with accurate and reliable guidance, ensuring your facility remains compliant. Remediation Should test results for water-borne pathogens or select metals result in detections above the GSA referenced criteria from the Centers for Disease Control and Prevention (CDC) and the U.S. Environmental Protection Agency (EPA), remedial actions to reduce the concentrations are required. Do not worry!HC3’s expertise can help coordinate and guide building owners/managers through the necessary remedial response actions, especially when dealing with pathogenic water-borne bacteria like Legionella.

BOOK AN APPOINTMENT NOW GSA Will Pay Up To $3500 For the Testing GSA reimburses the cost of baseline drinking water testing as required by GSA Order PBS 1000.7A, November 16, 2023. Costs are typically around $3,500. However, for certain buildings with complex water systems, the cost of baseline drinking water testing can exceed the typical amount. HC3 can prepare the necessary justification if baseline drinking water testing costs will exceed the allotted amount. This fee does not cover additional costs for response actions such as remediation costs should there be an exceedance of select water-borne pathogens or metals detections above the GSA referenced criterias.

Expert Answers

GSA water testing FAQ

Answers on scope, compliance, and how HC3 supports your facility.

Legionnaires' disease is a severe form of pneumonia caused by inhaling aerosolized water containing Legionella bacteria — most commonly Legionella pneumophila. It spreads from building water systems such as cooling towers, hot water loops, showers, and decorative fountains — not through person-to-person contact.
Immediately restrict exposure (e.g., shower restrictions, cooling tower shutdown if indicated), preserve sampling evidence, notify public health partners, and engage an experienced industrial hygiene team. HC3 provides outbreak response, forensic sampling, chain-of-custody documentation, and remediation planning aligned with CDC and ASHRAE guidance.
A WMP is a documented plan to identify, monitor, and control Legionella in building water systems. ASHRAE Standard 188 and CDC guidance recommend WMPs for healthcare, hospitality, and complex facilities. HC3 helps develop, audit, and implement defensible programs grounded in exposure science.
Frequency depends on building type, water system complexity, prior results, and regulatory context. Many healthcare facilities sample quarterly or after remediation events. HC3 designs sampling strategies tailored to your system — including pre- and post-remediation validation — rather than one-size-fits-all schedules.
Culture methods (ISO 11731) remain the regulatory gold standard but take 7–10 days. PCR detects DNA rapidly but may not distinguish live from dead organisms. MICA Advance offers culture-based results in approximately 48 hours — preserving scientific rigor with faster turnaround for operational decisions.
Yes. HC3 provides forensic corrective action when Legionella is identified — including root-cause analysis, disinfection validation, recurrence prevention, and documentation for regulators, insurers, and legal counsel. Remediation is evidence-based, not surface disinfection alone.
