Keywords: Laboratory, Coordination, Data Validation

ddms' staff posses over 25 years of experience in providing quality environmental chemistry services on CERCLA and RCRA projects across the country. The staff at ddms has a thorough understanding of all phases of project coordination. Our personnel can assist to determine appropriate analytical methods to achieve the project goals, coordinate the analytical efforts with the laboratory, provide oversight or audits of field activities, track delivery of samples to the analytical laboratory, and follow the samples through the laboratory to help ensure on-time results. This benefits the project financially by placing personnel conversant in the process in a position to address routine issues.

ddms is proud to offer the following environmental chemistry consulting services.

Third-Party Data Validation and Verification Services

Whether the data receive a validation or an evaluation, professional judgment is applied as necessary and appropriate. Emphasis is placed on technical usability of the data as opposed to method compliance. Data that are method compliant may not be usable and, conversely, data that are usable may not be method compliant. ddms personnel offer years of laboratory experience and have performed data validation services for clients and sites ranging from small single-party sites to very large multi-party sites.

EPA guidance states that data validation is to be performed by a third party with respect to the entity that performed the sampling and that which performed the analysis. For this reason, ddms is ideally suited for performing focused data validation services.

Laboratory Coordination and Oversight

Laboratory coordination and oversight is a necessary part of any environmental sampling effort. Often times, significant time and resources are required to manage the day-to-day needs of keeping up with bottle-orders, associated analyses, methods and ensuring that detection limits are meeting or exceeding the level required the prevailing environmental standards. ddms posses a solid understanding in the complexities associated with laboratory analysis oversight and excels at bringing this experience to bare on environmentally impacted sites from large to small scale.

Laboratory Audits

Laboratory chemical analysis are expensive and potentially responsible party (PRP) groups want assurances that the laboratories that will be performing forthcoming analysis are operating within their stated parameters. ddms regularly provides on-site laboratory audits on behalf of single and multi-party potentially responsible party (PRP) groups.

Field Sampling Audits and Sample Collection Oversight

Environmental projects require detailed planning and monitoring in order to attain quality data for the basis of future project phases. Sampling and analysis programs need to be well planned so that the data are representative of the site as well as completed in a cost effective and timely manner. ddms offers experience in contributing towards SAP (Sampling and Analysis Plans) and QAPP (Quality Assurance Project Plan) and Intricate environmental projects can entail complex sampling and analysis events, which may require day-to-day supervision or management of the sampling and analysis program. Comprehensive coordination of the project is essential to its success. ddms has experience in providing on-site oversight of sampling efforts including on large scale sediment sampling projects.

Electronic Data Deliverable (EDD)
Preparation and Testing

EDDs are now an essential data management tool. ddms has worked with dozens of major national laboratories to set up and vet a myriad of different EDD formats including the EPA Region formats.

Litigation Support Services

Data defensibility is paramount in an environmental litigation environment. ddms would argue that the threat of litigation is reason enough to always collect and maintain defensible data in the first place. ddms staff offer experience in providing environmental litigation services from many aspects including serving as fact witnesses and professionally qualifying the reliability of large databases on a record-by-record basis.

Other products and services from Ddms


ddms: Environmental Data Services

This unique combination of expertise enables ddms to provide its clients with a true depth and understanding of not only environmental database systems, but also the myriad of analytical, field measurement, lithological and quality assurance data within. These projects generate reams of data in a myriad of formats from hard copy documents to spreadsheets to complicated proprietary databases.


ddms: Environmental Litigation Support

One of the most cost intensive aspects of any litigation is the simple day-to-day management and organization associated with tracking schedules, finding key documents and working through the mechanics of communicating and distributing data in a secure and appropriate fashion within the team.


ddms: Environmental Visualization

Earth and environmental visualization and analysis differs from environmental data management in that the latter is the process of organizing existing data and the former is the process of translating that data into knowledge through the utilization of sophisticated software.


ddms: EMIS

Ddms does not utilize a one tool fits all scenario approach, but instead listens to what the specific needs and challanges associated with any one effort are before recommending whether a third party system or custom implementation be utilized.


ddms: Database Services

A properly configured relational database can not only increase the speed and efficiency which data are accessed, but by connecting disparate pieces of data, can also yield new information that is not otherwise obvious. To make a database more accessible to more users, ddms's database administrators create user interfaces or forms which are commonly used to access and possibly enter data into a database.


ddms: GIS

ArcObjects is a programming language created by Environmental Systems Research Institute for its industry leading GIS applications including ArcGIS ArcMap®, ArcCatalog®, ArcToolBox®, ArcSDE®, ArcGIS ArcEngine®, ArcGIS ArcServer® and many other applications and extensions.
