The Compliance and Health Risks of Skipping E. coli and Total Coliform Testing in Industrial and Commercial Facilities

Total Coliform and E. coli testing is not just a regulatory checkbox—it’s a frontline defense against public health hazards. For industries and commercial facilities that supply, manage, or discharge water, the presence of microbial contaminants poses serious compliance liabilities and reputational risks. These tests are required by federal and state agencies—including the EPA, NYSDOH, and…

BOD₅ / COD / TSS – Essential Tests for Municipal and Industrial Discharge Compliance 

Wastewater from industrial and municipal sources must be carefully monitored to protect receiving waters like rivers, lakes, and coastal zones. Regulatory bodies such as the EPA, New York State Department of Environmental Conservation (NYSDEC), and New Jersey Department of Environmental Protection (NJDEP) require systematic testing for BOD₅ (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand), and…

Understanding Total Coliform and E. coli Testing – Why It’s Essential for Safe Drinking Water

Safe drinking water is a fundamental public health priority, and ensuring it is free from harmful bacteria is non-negotiable. Whether you’re a homeowner relying on a private well, a school administrator ensuring student safety, or a property owner dealing with the aftermath of a flood—testing for Total Coliforms and E. coli is one of the…

The Role of Electrical Conductivity and Sulfates in Corrosion Control

Among the many water quality parameters that affect HVAC system performance, electrical conductivity and sulfate concentration are two of the most overlooked yet impactful. These values offer insight into the chemical makeup of the water and are direct indicators of potential scaling and corrosion. When not monitored and controlled, elevated conductivity or sulfates can compromise…

Understanding pH, Alkalinity, and Hardness in HVAC Water Systems

In HVAC systems, water chemistry plays a critical role in system efficiency, component lifespan, and maintenance needs. Among the most fundamental parameters that influence system stability are pH, alkalinity, and hardness. These three interrelated factors determine whether your HVAC water is balanced, aggressive, or prone to scale formation. Understanding how they interact allows engineers to…

Why Water Quality Testing is Critical for HVAC System Longevity

Water is the lifeblood of HVAC systems, particularly in chilled water and boiler systems. These systems rely heavily on water as a heat transfer medium, making its quality a cornerstone of system performance. Poor water quality can trigger a cascade of operational problems—scaling, corrosion, microbiological fouling, flow restrictions, reduced heat exchange efficiency, and even equipment…
