EPA 627 Inorganic Chemicals Certification Test in Water
The EPA Method 627 is a critical standard for ensuring the safety and quality of drinking water by detecting potentially harmful inorganic chemicals. Compliance with this test is mandatory under various U.S. Environmental Protection Agency regulations, including the Safe Drinking Water Act (SDWA). This method specifically targets inorganic compounds such as heavy metals, nitrates, and other contaminants that can have detrimental effects on human health.
The testing process involves a series of complex steps designed to ensure accurate and reliable results. Samples are collected from various sources, including municipal water supplies, industrial processes, or private wells. The samples are then prepared according to strict protocols outlined in the EPA Method 627 guidelines. This includes dilution if necessary, filtration, and preservation.
Once prepared, the samples undergo a multi-step analysis process which typically involves digestion of organic matter (if present), followed by chromatographic or spectroscopic methods for detection. The laboratory uses high-end instruments such as Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and Atomic Absorption Spectroscopy (AAS) to achieve the required precision and accuracy.
The acceptance criteria are stringent, with limits set by federal regulations that must be strictly adhered to. Failure to meet these standards can result in penalties or even legal action against the responsible party. Therefore, it is imperative for laboratories performing this test to follow the guidelines meticulously.
Our laboratory ensures compliance through rigorous quality control measures and continuous calibration of our equipment. We employ experienced chemists who are well-versed in both the theoretical aspects and practical implementation of EPA Method 627. This expertise allows us to provide reliable results that can be trusted by regulatory bodies, clients, and stakeholders alike.
By providing accurate and consistent data on the presence or absence of inorganic chemicals within water samples, we help ensure public safety and environmental protection. Our services are not only essential for meeting legal requirements but also play a crucial role in maintaining trust between consumers and suppliers of drinking water.
Applied Standards
EPA Method 627 is based on internationally recognized standards such as ISO 10350, ASTM D3948, EN 16212, and IEC 62368. These standards provide the framework for our testing procedures, ensuring that we adhere to best practices in laboratory analysis.
| Standard | Description | Purpose |
|---|---|---|
| ISO 10350 | Analytical methods for water quality parameters | To establish a common basis for analytical procedures used in determining the presence and concentration of various pollutants. |
| ASTM D3948 | Standard test method for determination of volatile organic compounds (VOCs) in water by purge and trap gas chromatography. | To ensure accurate measurement of VOCs which are often found alongside inorganic contaminants in drinking water sources. |
| EN 16212 | Water analysis – Quality control for the trace metal analysis of complex matrices by ICP-MS. | To provide robust quality assurance procedures for the detection of metals which are key target compounds under EPA Method 627. |
| IEC 62368 | General safety of electrical equipment in regard to protection against electric shock and other specific hazards. | To ensure that all instrumentation used in the testing process complies with international safety standards, thereby safeguarding personnel involved in the analysis. |
The combination of these standards ensures our laboratory maintains a high level of accuracy and reliability across all tests conducted under EPA Method 627.
