Surface Water Pollutant Testing
In the realm of environmental pollutant testing, surface water plays a pivotal role in maintaining ecological balance and human health. Surface water bodies such as lakes, rivers, and streams are critical natural resources that supply drinking water, support aquatic life, and provide recreational opportunities. However, these waters can be susceptible to various pollutants from anthropogenic activities, leading to degradation of water quality.
Our laboratory specializes in the analysis of surface water samples to identify and quantify pollutants such as heavy metals, organic compounds, nutrients, pathogens, and other contaminants that may pose risks to human health and aquatic ecosystems. This service is essential for compliance with regulatory standards, water quality monitoring, and research purposes.
Surface water pollution can arise from point sources like industrial discharges or non-point sources such as agricultural runoff and urban stormwater. The pollutants include physical parameters (temperature, turbidity), chemical constituents (pH, salinity), organic compounds (volatile organic compounds, polycyclic aromatic hydrocarbons), and biological indicators.
Our testing process involves the collection of water samples from specified locations, ensuring that they are representative of the entire body of water. Sample preparation includes filtration, digestion, and concentration steps to enhance detection sensitivity. The analysis employs a range of sophisticated instruments and techniques, including inductively coupled plasma mass spectrometry (ICP-MS), gas chromatography-mass spectrometry (GC-MS), high-performance liquid chromatography (HPLC), and microbiological culturing methods.
Compliance with regulatory standards is paramount. We adhere to international norms such as ISO 17025 for method validation, EPA Method 3050B for total petroleum hydrocarbons in water, and the USEPA's National Primary Drinking Water Regulations (NPDWR). Our laboratory also follows local legislation, ensuring that our clients meet all necessary requirements.
The results of our tests provide actionable insights into water quality issues. These findings are crucial for stakeholders involved in environmental management, public health, and industrial processes. By identifying pollutants early, corrective actions can be implemented to prevent further contamination and protect the environment.
Scope and Methodology
| Parameter | Test Method | Instrumentation |
|---|---|---|
| Total Suspended Solids (TSS) | ASTM D4260-18 | Beta Attenuation Monitor (BAM) |
| Lead and Arsenic | ISO 7259:2007 | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) |
| Biochemical Oxygen Demand (BOD) | EPA Method 521.2 | Aerobic Incubation System |
The scope of our surface water pollutant testing encompasses a wide array of parameters, including but not limited to heavy metals, pesticides, pharmaceuticals, and pathogenic microorganisms. Each test follows rigorous methodologies tailored to the specific parameter being analyzed.
For heavy metal analysis, we utilize ICP-MS which provides high sensitivity and precision. Pesticide detection employs GC-MS for accurate identification and quantification of residues. Nutrient testing involves colorimetric assays that measure nitrate and phosphate levels. Pathogen detection is conducted through membrane filtration followed by microbiological culturing.
