We offer laboratory and in-field testing of sediments, sludges, and industrial residuals to inform remediation strategies. Our studies support proper material handling, water treatment methodologies, and permit compliance. Using the data our experienced chemists acquire, we implement the most cost effective, full-scale solution for your remediation project.

Comprehensive Lab Studies We Perform

  • Chemical flocculant, coagulant, and polymer optimization
  • Soil amendment trials
  • Geotextile tube dewatering tests (GTDT)
  • Paint filter and compressive strength analysis
  • Turbidity and total suspended solids (TSS)
  • Mechanical dewatering and processing trials
  • Rapid dewatering tests (RDT)
  • Wastewater treatability study

Before committing to full-scale dredging, water treatment, or sediment disposal, you need to know what you’re dealing with. Our treatability testing services generate the site-specific data that drives smarter design, efficient permitting, and smoother implementation. From small lab trials to scaled pilot tests, we help you reduce uncertainty, manage costs, and ensure regulatory compliance.

Our in-house laboratory supports a full range of testing to inform your environmental project:

Jar Testing
To determine which chemical flocculants, coagulants, or polymers work best in your site’s water or sediment conditions.

Sediment Amendment Trials
Testing additives or stabilizers to assess if contaminated sediments can be treated in situ, or whether they meet criteria for beneficial reuse.

Rapid Dewatering Tests (RDT) & Geotextile Tube Dewatering Tests (GTDT)
These evaluate how quickly water can be removed from dredged material and what system (geotextile tubes, belt press, etc.) performs best. The GTDT (“pillow test”) also helps assess how the dewatering fabric handles water flow, suspended solids, and filtration.

Mechanical Dewatering & Processing Trials
Evaluating equipment and methods like plate & frame presses, belt filter presses, etc., to see which will work best in your project, considering material type, costs, footprint, and performance.

Water Treatment Bench-Scale Testing
Bench-scale (lab-scale) filters, clarification, settling, and tests for filtration, activated carbon or ion exchange, to determine the best treatment approach for water or wash-off streams.

Chemical Conditioning & Polymer Screening
Identify effective conditioning protocols (including polymer types and doses) to improve dewatering performance and ensure filtrate quality.

Disposal & Beneficial Use Criteria Analysis
Includes paint filter tests, compressive strength tests, and other analyses to verify whether treated materials can meet regulatory or reuse thresholds.

Turbidity / Total Suspended Solids (TSS) Monitoring
Assessment of how much solid matter remains in water after treatment or during dewatering operations—a key criteria for regulatory compliance.
