White Papers

Recently, ddms was proud to be a sponsor for the 2021 International Conference of Environmental Data Management (ICEDM). Many of our own attended, and even were panelists and presented our thoughts on the latest trends on Environmental Data Management.

In order to implement a system that meets our clients’ needs, we perform a comprehensive assessment of business needs and user expectations.

The California State Water Resources Control Board has adopted new regulations that update the State’s Environmental Laboratory Accreditation Program (ELAP) requirements.

Data users might think that the number of qualifiers applied to results is inversely proportional to the quality of the results. In most instances, this is not the case.

Putting together a good quality assurance project plan (QAPP) just may be the most important thing you do to ensure that your project achieves the desired goals.

Whenever the reliability of the laboratory data can be called into question, an independent, third party assessment of the data (i.e. data validation) will play an important role.

The National Pollutant Discharge Elimination System (NPDES) permit program, created in 1972 by the Clean Water Act (CWA), was designed to help manage pollutants that reach water sources in the United States.

Emerging contaminants like per- and polyfluoroalkyl substances (PFAS) are relatively new to the laboratories, and methods have not been long-established, like those for the more familiar analyses such as volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs).

Until the early 2000’s, 1,4-dioxane has received little attention from regulatory agencies. This compound is a frequent contaminant of concern at sites contaminated with chlorinated compounds, due to its widespread use as a stabilizer for chlorinated solvents.

As regulatory agencies push action limits lower and lower, laboratories have had to move to increasingly more sensitive methodologies for analyses in order to meet their clients’ needs.
