Water Risk Management
EHS can reduce health risks due to pathogens in water systems. We bring customers years of experience. Starting over a decade ago, Nalco’s groundbreaking work in risk reduction has provided guidance in establishing a global approved code of practice for Legionella control. Our approach is to provide an assessment of a customer's facility to identify and reduce risks before they affect employees and guests.

We offer a portfolio of services to address concerns about waterborne pathogens, and we have developed a model that first identifies and quantifies risks, develops an action plan, and employs turn-key remediation services when needed. It then holds the gains through control and legionella analysis, followed by periodic reviews, including re-assessment of risks, with people in your organization.

Backing our specialists is a team of researchers and technicians who have studied the issues related to legionella. Using their global expertise, we have developed a risk assessment and turn-key remediation service program that can be customized to reduce risk and potential liability from water systems. No two problems or solutions are identical.

HVAC Air Management
Our mission is to restore and to boost the cooling and heating capacity of HVAC systems, while providing Indoor Environmental Quality (IEQ) solutions that reduce the risk of airborne pathogens, contaminants or other environmental hazards.

Our specialized consulting team customizes the solutions to your specific HVAC operation needs and performance goals such as cooling capacity, air quality, reduction in energy cost and environmental footprint.
