Water quality has a critical and direct effect on the health and welfare of not only humans, but also all other forms of animal and plant life. Rapidly expanding global populations and increasingly scarce clean water resources make proper water and wastewater treatment absolutely essential to protecting life as we know it in the long-term. 

Water and wastewater sampling is the first step in measuring and documenting compliance with local, state and federal rules and regulations which safeguard water quality, e.g., the Environmental Protection Agency (EPA) and standards stipulated in the Clean Water Act and the Safe Drinking Water Act. Without this technology, the well-established procedures for gathering valuable field data to drive the science and assure compliance begins to fall apart.

Mar​​kets

Both the influent and effluent quality must be maintained in a variety of manufacturing and production processes. Water sample purity is vital to conducting virtually any experiment in the lab and to creating pharmaceuticals that improve the quality of life. Whether drinking water, stormwater, sewage and wastewater, lakes and streams, even the chlorine levels and pH balances in a swimming pool, sample collection and laboratory testing are crucial.

 

Locatio​ns where water and wastewater surveillance and treatment play a major role:
  • Municipal Drinking Water Treatment Plant
  • Wastewater Treatment Plant/Publicly Owned Treatment Works
  • Urban Stormwater Systems, e.g., runoff from city streets containing oil, road salt, metals, as well as a wide range of organics
  • Surface Water Quality/Total Maximum Daily Load (TMDL) & Watersheds
  • Industrial Process Control/Compliance
  • Source Control/Pretreatment
  • Agricultural runoff, e.g., nitrogen from fertilizer, pathogens from animal waste, chemical pollutants derived from herbicides & insecticides
  • New construction runoff in industrial and residential locations
  • Landfill leachate, e.g., methane, sulfides, and VOCs (volatile organic compounds)
  • Surveillance for Pathogens & Other Targeted Substances
    • Bacteria
    • Diseases, e.g., Covid, measles, mumps
    • Metals
    • Forever Chemicals, e.g., PFAS
    • Other Chemicals
    • Manufacturing and Production Byproducts
    • Illicit Drugs
  • Industrial Pre-Treatment Monitoring
    • Allows the treatment plant to plan for treatment options
    • Used to identify a source of non-compliant discharge water
    • Enforcement
  • Academia

 

Some types of water and ​wastewater testing
  • Biochemical Oxygen Demand (BOD)
  • Chemical Oxygen Demand (COD)
  • Suspended Solids
  • Nutrient Levels
  • Pharmaceutical​

Water and Wastewater Samplin​​g Techniques

The most important rule of collecting water samples is . . . the sample must represent the source. Water sampler needs and operation parameters vary by location, application and desired results. Maintaining confidence in those outcomes is imperative.​

Questions​ &​​ Answers

What is meant by water ​treatment?

Water treatment removes contaminants to improve the quality of water to create an appropriate level of purity for drinking; industrial water supply; laboratory water supply; wastewater treatment of sewage or industrial waste prior to returning water to the environment; maintaining safe and healthy lakes, streams and rivers. 

What is BOD and COD in water treat​ment?

Biochemical Oxygen Demand (BOD) is a measure of the amount of oxygen consumed by microorganisms to break down organic matter in a water sample over a set period. Chemical Oxygen Demand (COD) is a measure of the total amount of organic matter that can be oxidized by chemical agents. 

Why is water and wastewater treatment es​​sential?

Human, animal and plant health and welfare depend on water supplies that are safe and free from harmful contaminants that can communicate diseases and otherwise impact the quality of life and the environment. Contaminant levels in water and wastewater are closely measured and treated to comply with expansive local, state and federal rules and regulations. ​​
