What Is Total Organic Carbon (TOC) Testing?
Total Organic Carbon (TOC) testing is an analytical technique used to determine the concentration of carbon present in organic compounds within a sample.
TOC is an important water quality parameter because it provides a measurement of the total amount of organic carbon present without requiring the identification of each individual organic compound.
Organic carbon can originate from natural and human-made sources, including:
-
Decomposing plant and animal material
-
Industrial wastewater and manufacturing processes
-
Agricultural runoff
-
Municipal wastewater
-
Natural organic matter in surface water and groundwater
-
Organic chemicals and industrial residues
-
Biological activity and organic contamination
Total Organic Carbon analysis helps organizations evaluate organic loading, investigate changes in water quality, and monitor treatment processes.

Why Is Total Organic Carbon Testing Important?
Total Organic Carbon testing provides valuable information about the organic content of water and other applicable liquid samples.
1. Water Quality Monitoring
TOC measurements help assess organic carbon concentrations in groundwater, surface water, and water treatment systems.
2. Industrial Wastewater Testing
Manufacturing and industrial facilities use TOC data to characterize organic loading and evaluate changes in wastewater composition.
3. Environmental Investigations
Environmental consultants use TOC analysis to support site assessments, water quality studies, and investigations involving organic material.
4. Water Treatment Efficiency
Comparing TOC concentrations before and after treatment can help evaluate the removal of organic carbon during treatment processes.
5. Process Water Quality
Industries may use TOC monitoring to identify changes in process water quality and investigate potential organic contamination.
6. Drinking Water Treatment
TOC is an important parameter in evaluating natural organic matter that may contribute to disinfection byproduct formation during drinking water treatment.
Total Organic Carbon Testing Methods
Laboratory TOC analysis typically involves converting organic carbon in a sample into carbon dioxide, which is subsequently measured using analytical instrumentation.
Common analytical methods include:
EPA SW-846 Method 9060 – Total Organic Carbon
EPA Method 9060 is used for determining organic carbon concentrations in groundwater, surface water, saline water, and domestic or industrial wastes.
EMSL identifies Method 9060 in its published TOC testing service information.
EPA Method 415.3 – Total Organic Carbon in Drinking Water
EPA Method 415.3 addresses TOC analysis in source water and drinking water. It is particularly relevant to drinking water treatment and organic carbon monitoring.
Standard Methods 5310 – Total Organic Carbon
Standard Methods 5310 includes analytical procedures used for measuring organic carbon in water.
The appropriate analytical method depends on the sample matrix, required reporting limits, regulatory requirements, and laboratory capabilities. Contact EMSL to confirm method availability for your project.
Industries That Need TOC Testing
Total Organic Carbon testing supports numerous industries and applications.
Environmental Consulting
Environmental consultants use TOC measurements to support groundwater investigations, surface water monitoring, environmental site assessments, and water quality studies.
Water and Wastewater Treatment
Municipal and industrial treatment facilities use organic carbon measurements to understand water characteristics and assess treatment performance.
Manufacturing and Industrial Facilities
Industrial operations may use TOC analysis to monitor process water, wastewater, and changes in organic loading.
Pharmaceutical and Biotechnology Manufacturing
TOC monitoring is widely used in pharmaceutical water quality programs. Projects involving pharmaceutical-grade purified water or water for injection may require specialized low-level TOC testing under applicable standards. Contact EMSL to confirm whether the required testing and reporting limits are available.
Food and Beverage Manufacturing
Food and beverage facilities may use TOC monitoring in water quality programs, cleaning assessments, and wastewater management.
Environmental Engineering
Engineering firms use TOC data to support treatment system evaluations, environmental investigations, and industrial water management projects.
TOC Testing vs. COD and BOD Testing
Total Organic Carbon (TOC), Chemical Oxygen Demand (COD), and Biochemical Oxygen Demand (BOD) are different analytical measurements used to evaluate water and wastewater characteristics.
Total Organic Carbon (TOC): Measures the concentration of organic carbon in a sample.
Chemical Oxygen Demand (COD): Measures the oxygen equivalent of chemically oxidizable substances in a sample.
Biochemical Oxygen Demand (BOD): Measures oxygen consumed by microorganisms during the biological degradation of material under specified test conditions.
Each parameter provides different information. Depending on the project, multiple tests may be appropriate for a comprehensive water quality assessment.

Frequently Asked Questions About TOC Testing
What does TOC testing measure?
TOC testing measures the concentration of organic carbon in a sample. Results are commonly expressed in milligrams of carbon per liter (mg/L) for water samples.
What is the purpose of Total Organic Carbon testing?
TOC testing helps determine organic carbon concentrations for water quality monitoring, wastewater characterization, treatment process evaluation, and environmental investigations.
Can TOC testing detect organic contamination in water?
TOC testing can indicate the presence and concentration of organic carbon, but it does not identify specific organic contaminants. Additional chemical testing may be necessary to identify individual substances.
What is the difference between TOC and DOC?
Total Organic Carbon (TOC) measures organic carbon in the sample, including dissolved and particulate fractions as applicable to the method. Dissolved Organic Carbon (DOC) measures the fraction passing through a specified filter, commonly 0.45 micrometers.
How long does TOC laboratory testing take?
Turnaround time depends on sample type, laboratory scheduling, and analytical requirements. Contact EMSL Analytical for current TOC testing turnaround times and pricing.
Where can I get Total Organic Carbon testing?
EMSL Analytical offers Total Organic Carbon testing services for applicable water samples. Customers can contact EMSL to discuss sample submission, analytical methods, and laboratory availability.
Does TOC testing identify bacteria or specific organic chemicals?
No. TOC testing measures organic carbon rather than identifying individual microorganisms or chemicals. Microbiological or compound-specific chemical analysis may be needed for those purposes.
