Environmental Laboratory

ETLCO offers comprehensive pickup and sampling services, providing field support tailored to the needs of our clients. We understand the importance of efficient schedule coordination and the timely completion of projects, which is achieved through close collaboration between Project Management and Sample Coordinators.

Our highly trained and equipped staff ensures the success of each sampling event.

Our sampling services include Groundwater Well Sampling, Dewatering Well Sampling, Surface Water Sampling, Industrial and Sanitary Wastewater Sampling, Soil, Sludge, and Sediment Sampling, Solids and Non-Aqueous Waste Sampling, Hazardous Industrial Waste Sampling, Drinking Water Network Sampling, Seawater Inlet, Desalination, and Outfall Sampling, and other specific services as required.

Water quality testing services are essential for evaluating the chemical, physical, and biological characteristics of water, wastewater, groundwater, seawater, and other water matrices. These services help ensure compliance with environmental regulations, safeguard public health, and support industrial and agricultural applications.

ETLCO provides a comprehensive water quality assessment service to evaluate the chemical, physical, and biological characteristics of water to determine its suitability for various uses, such as drinking, industrial, groundwater, and agricultural applications.

Key Parameters Tested:

• pH
• Turbidity
• Dissolved Oxygen (DO)
• Biochemical Oxygen Demand (BOD)
• Chemical Oxygen Demand (COD)
• Total Dissolved Solids (TDS)
• Nitrates
• Phosphates
• Chlorides
• Heavy Metals
• Volatile Organic Compounds (VOCs)
• Semi-Volatile Organic Compounds (SVOCs)
• Total Petroleum Hydrocarbons (TPH)
• Total Chlorinated Hydrocarbons (TCH)
• Trihalomethanes (THMs)
• Pesticides
• Microbial Contaminants

Our services involve sampling, laboratory analysis, and interpretation of results to identify contaminants and determine the water's suitability for specific uses. This thorough process ensures that your water sources are safe, compliant, and fit for their intended purposes.

ETLCO’s soil sampling and analysis services provide comprehensive solutions for assessing soil quality, contamination levels, and suitability for various uses. These services are critical in environmental management, regulatory compliance, land development, and agricultural productivity.

Our soil analysis process involves the collection of soil samples, laboratory analysis, and interpretation of results to inform decision-making. Key parameters include:

• pH
• Organic Matter
• Total Organic Carbon (TOC)
• Nitrogen (N)
• Phosphorus (P)
• Potassium (K)
• Heavy Metals
• Salinity
• Moisture Content
• Cation Exchange Capacity (CEC)

These analyses support informed decision-making for soil management, crop production, and environmental protection, ensuring that your projects comply with regulatory requirements and promote sustainable land use practices.

The testing focuses on identifying harmful organic compounds that pose risks to health and ecosystems due to their persistence in the environment.

The laboratory performs advanced analyses, including Tentatively Identified Compounds (TIC) through VOC and SVOC library searches on a GC-MS system, addressing client-specific needs with expanding capabilities. Skilled analysts and chemists deliver high-quality results with swift turnaround times.

Methodologies include EPA SW-846 Methods 8260, 8270, and 8015 for VOC, SVOC, and non-halogenated organic compounds, as well as TPH analysis by US EPA Method for water, soil, and solids.

Instrumentation includes GC-MS/P&T and GC-FID/HS with auto samplers from top manufacturers. Key tests cover TOC, TCH, THMs, BTEX, phenols, pesticides, PCBs, herbicides, VOCs, SVOCs, organic solvents, and TPH (aggregate and fractionated).

Hazardous waste testing is essential for determining the chemical composition and toxicity of waste materials to ensure proper classification, handling, and disposal, minimizing environmental impact and maintaining regulatory compliance.

ETLCO provides waste characterization analyses compliant with RCER2015 and EPA standards, employing USEPA SW-846 methods and EPA water matrix protocols. Key tests include TCLP (Toxicity Characteristic Leaching Procedure), assessments of corrosivity, reactivity, ignitability, and analyses for VOCs, heavy metals, pesticides, etc.

Metals analysis is routinely conducted by our experienced and highly qualified staff, using samples from various sources such as municipal, commercial, and petrochemical/industrial sectors. These samples are analyzed across water, wastewater, sludge, and solid matrices.

Our state-of-the-art instrumentation includes ICP-MS, ICP-OES, and ICP-OES with a Hydrogen Generation Kit. We utilize recognized methodologies from US EPA, APHA, and ASTM to carry out these analyses.

ETLCO understands the importance of timely analysis and reporting to meet the needs of our clients. We offer flexible reporting formats tailored to specific requirements, which can be discussed in consultation with the client before the project begins.

Microbiological testing is crucial for detecting and quantifying microbial contaminants that may present health risks in water, soil, or air samples. This testing encompasses a range of parameters, including total coliforms, E. coli, fecal coliforms, total plate count, Legionella, and pathogenic bacteria.

By identifying these potential hazards, we help ensure the safety and quality of the environment and safeguard public health. Our microbiological testing services are essential in various industries, including environmental monitoring, water treatment, public health, and food safety.
