Water and Environmental Testing

Introduction to Water & Environmental Testing Services

Infinita Lab’s ASTM Water and Environmental Testing Services facilitate the rigorous evaluation of water quality and environmental media. These services ensure that client products and operational processes adhere to established industry benchmarks for performance, safety, and regulatory alignment. Utilising advanced analytical methodologies, we characterise the chemical, physical, and biological attributes of water, soil, sediment, and air samples. These evaluations support diverse applications, including potable water treatment, industrial process water management, wastewater oversight, environmental remediation, and geotechnical investigations.

By leveraging a broad network of accredited laboratories across the United States, we offer an extensive portfolio of ASTM-compliant testing solutions. These services are structured to facilitate environmental quality assurance, verify regulatory compliance, investigate potential contamination, and support industrial water treatment initiatives.

Our Water & Environmental Testing Services

Water Quality Testing

Water quality testing analyses various water sources – including drinking water, groundwater, surface water, boiler feedwater, cooling water, and wastewater – to detect contaminants, monitor treatment effectiveness, and ensure compliance with health and environmental regulations. Our water quality testing services cover physical, chemical, and ionic parameters essential for complete water characterisation.

• ASTM D516 – Sulfate ion determination in water, evaluating the sulfate concentration that contributes to scaling, corrosion, and biological activity in water distribution and industrial systems.

Dissolved Solids, Residue & Suspended Solids Testing

Dissolved and suspended solids in water affect turbidity, treatment efficiency, equipment fouling, and regulatory compliance. Accurate measurement of filterable and non-filterable residue is essential for wastewater characterisation and industrial water management.

Relevant ASTM Standards:

• ASTM D5907 – Filterable and non-filterable matter in water, measuring both dissolved (filterable) and suspended (non-filterable) residue fractions – essential parameters for wastewater characterisation, effluent discharge compliance, and treatment process monitoring.
• ASTM D6502 – On-line integrated measurement of low-level suspended solids and ionic solids in process water by X-ray fluorescence (XRF), providing continuous monitoring of corrosion products and particulate metals in power plant steam and water circuits – supporting heat transfer efficiency and plant reliability.

Carbon & Oxygen Demand Testing

Carbon and oxygen demand parameters are critical indicators of water quality, organic contamination, and biological oxygen demand in water treatment systems, supporting process control in wastewater treatment plants, industrial effluent monitoring, and drinking water compliance.

Relevant ASTM Standards:

• ASTM D5997 – Online monitoring of total organic carbon (TOC) and total inorganic carbon (TIC) in water from industrial, drinking water, and wastewater sources – the standard method for identifying and quantifying organic and inorganic carbon impurities in power, pharmaceutical, semiconductor, and waste treatment applications.
• ASTM D6238 – Total oxygen demand testing in water, providing a measure of the total oxidizable material in water samples – used as a screening test for assessing the oxidizable organic load in industrial wastewater and environmental water samples.

Soil & Sediment Testing

Soil and sediment testing assesses the physical and chemical properties of soil, including composition, contamination levels, and suitability for construction, agricultural, or environmental use. These tests are fundamental for environmental impact assessments, remediation planning, and geotechnical site investigations.

Relevant ASTM Standards:

• ASTM D2487 – Soil classification using the Unified Soil Classification System (USCS), categorising soils by grain size, plasticity, and other physical properties to characterise their suitability for construction and environmental applications.

• ASTM D2435 – One-dimensional soil consolidation properties testing, measuring how soils compress under incremental loading – essential for predicting settlement of structures and embankments founded on compressible soils.

Air Quality Testing

Air quality testing measures the concentration of pollutants in air – including particulate matter, volatile organic compounds (VOCs), and other hazardous substances – ensuring that air quality meets environmental standards, worker safety regulations, and product emissions requirements.

• ASTM D1356 – Standard terminology for sampling and analysis of atmospheres, providing the definitional framework for air quality monitoring, pollutant characterisation, and atmospheric sampling procedures used in environmental and industrial air quality programs.

Process Water & Industrial Water Testing

Industrial process water – including boiler feedwater, cooling water, steam condensate, and power plant water circuits – must be rigorously monitored for ionic contaminants, corrosion products, dissolved gases, and organic impurities to ensure equipment reliability, heat transfer efficiency, and process integrity.
