Water quality compliance testing

End-to-end testing solutions for water quality compliance

Whether you're managing a single discharge permit or a multi-site monitoring program, ALS provides full-scope testing and expert regulatory support for wastewater, stormwater, groundwater and surface water.

We have decades of technical expertise operating accredited labs offering nationwide coverage and responsive service. This focus on expertise and service is how our company has been built to meet client needs.

Industries we serve

Strong integrated teams offer accurate, timely results and expert guidance throughout every step of a project or multi-year contract — from permitting and sampling to fast analysis and reporting for a range of industries, including:

  • Industrial and manufacturing facilities
  • Utilities and municipalities
  • Engineering and environmental consultants
  • Construction and infrastructure developers
  • Department of Defense (DOD) and government agencies
  • Energy, mining and land development projects

Our approach to client service simplifies project coordination through proactive communication and status updates, responsive testing specialists and mobile tech field teams.

Our expert chemists can assist in tailoring analyte packages and provide sampling media for requested target compounds, backed by rigorous QA/QC, and data reporting tailored for permitting, compliance or litigation.

Our compliance focus

  • RCRA (Resource Conservation and Recovery Act)
  • CERCLA/Superfund (Comprehensive Environmental Response, Compensation and Liability Act)
  • UST/LUST (underground storage tank programs)
  • Construction and dewatering permits
  • Surface water quality standards (state and EPA guidance)
  • Clean Water Act (CWA)
  • National Pollutant Discharge Elimination System (NPDES)

Wastewater: NPDES and industrial discharge monitoring

Our labs provide full analytical services and support for testing wastewater and trade effluents to help facilities meet permit conditions under the CWA and NPDES.

Scope of services

  • Process wastewater and treatment plant effluents
  • Discharge monitoring reports (DMRs)
  • Industrial pretreatment program (IPP) compliance
  • Permit sampling, flow surveys and reporting

 

Typical Analyses

  • BOD, COD, pH, TSS, ammonia, nutrients
  • VOCs (8260), SVOCs (8270), PFAS (1633, 537.1, 533)
  • Heavy metals (ICP-MS, CVAA, hexavalent chromium)
  • Oil and grease, petroleum hydrocarbons (TPH, EPH, VPH)
  • Microbiology (E. coli, total coliforms)
  • Site-specific contaminants (cyanide, sulfide, TOC)

Stormwater: industrial, construction and MS4 monitoring

Stormwater discharges regulated under CWA Section 402 require specialized testing tied to SWPPP plans and general permit requirements. With field-ready sampling kits and courier coordination, we can deliver on fast TAT to meet storm event sampling windows.

Permit Types

  • Industrial General Permit (IGP)
  • Construction General Permit (CGP)
  • MS4 (Municipal Separate Storm Sewer System) programs

 

Typical Analyses

  • TSS, pH, oil and grease, turbidity
  • BOD/COD, nutrients (nitrate, ammonia, TKN)
  • Metals and indicator pollutants
  • Bacteria (E. coli, Enterococci)

Groundwater: site characterization and long-term monitoring

We provide analytical services for site investigation, monitoring and remediation governed by:

  • RCRA (Resource Conservation and Recovery Act)
  • CERCLA/Superfund
  • UST/LUST Programs
  • State-mandated groundwater cleanup criteria

Common applications

  • Environmental site assessments (phase II, III)
  • Remediation system performance monitoring
  • Construction dewatering and land development
  • Landfill, mining and industrial groundwater compliance

 

Typical analyses

  • VOCs (8260), SVOCs (8270), 1,4-dioxane
  • PFAS (EPA 533, 537.1, 1633)
  • Metals (including mercury, arsenic and hexavalent chromium)
  • Nutrients, fluoride, TOC, TDS, alkalinity
  • Microbiology and indicator parameters

Surface water: monitoring for environmental impact and permitting

Our experienced teams help clients assess and maintain surface water quality in accordance with:

  • State water quality standards
  • Clean Water Act (303d listings, TMDLs)
  • Watershed impact studies and development permits

Clients and applications

  • Land development and infrastructure projects
  • Industrial site runoff impact assessments
  • Public utility monitoring programs
  • Environmental and ecological studies

 

Typical parameters

  • Field and lab analysis of pH, turbidity, temperature, DO
  • Nutrients, chloride, sulfate, TSS, TOC
  • Bacteria (E. coli, Enterococci)
  • Metals, organics, pesticides, and PCBs
  • PFAS and emerging contaminants
