Walden’s scientists are highly experienced in lab consulting. We develop Sampling Plans, help identify qualified laboratories, and manage data collection activities. Once field sampling is completed, Walden evaluates test results and prepares reports of findings with recommendations for site closure, additional investigation or remediation as appropriate.

Air Quality Studies

Walden can assist with air quality studies by developing plans to determine appropriate testing parameters and protocols to address areas of concern. In addition, we are able to interpret results and assist with the development of remediation protocols if required.

Wastewater Sampling

Prior to mandated wastewater sampling, a sampling plan that meets current sample collection regulations is required. Walden’s experienced technical personnel can provide a written wastewater sampling plan to meet your needs.

Soil and Solid Waste Sampling

Soil and solid waste sampling requires specific knowledge, experience and specialized equipment for proper sample collection and preservation that complies with current regulations. Walden’s technical staff has extensive experience in the use of all required equipment and sampling techniques specific to soil and solid waste sampling.

Correlation Studies

Walden’s experienced scientists can design and perform correlation studies in order to determine the relationship between analytical sample results and environmental issues and assist with implementing any required remediation protocols.

Stormwater Sampling

Regulations require monitoring and control measures to confirm compliance with industrial and construction site stormwater permits. Walden can assist with interpretation of stormwater sampling results and development of control measures to achieve and maintain regulatory compliance.

Quality Assurance Project Plans

A Quality Assurance Project Plan defines the objectives and procedures required to assure the reliability and quality of environmental data studies. The quality of the plan is critical to ensure that the results are scientifically sound and legally defensible. Walden’s experienced scientists can provide detailed QAPPs and technical guidance specific to suit your project needs.

Waste Characteristic Sampling

Regulations require wastes generated by industrial processes to be properly handled and disposed. In addition, waste materials must be characterized for acceptance at appropriate disposal facilities. Waste characterization is required to classify the materials. Walden can provide guidance with waste characteristic sampling planning and interpretation of results.

Laboratory and Facility Audits

Walden offers a comprehensive range of auditing services and can perform a detailed assessment of your facility and your contract laboratories. Assessments include the identification of potential environmental regulatory compliance deficiencies, recommendations and guidance for improvements and development of remediation procedures and processes if required.

Evaluation and Validation of Laboratory Results

Walden’s experienced technical professionals can review analytical test reports and evaluate results. We provide recommendations to assist you with respect to your current needs and requirements. Walden also performs data validation in accordance with standard practices and USEPA guidance to ensure that the analytical laboratory data is usable and that all laboratory protocols have been followed.

On-Site Sampling

Walden can assist your company by providing experienced technical personnel to conduct on-site sampling which complies with all current approved sample collection and preservation requirements. Sampling can include the use of real time data collected using calibrated instruments or qualified laboratory results depending on the project needs.

Temporary Lab Director Services

Walden’s staff includes a former laboratory director who understands laboratory standards, equipment, calibration, quality controls and recordkeeping. We can assist clients in setting up and improving their laboratory operations.
