Reliable Sampling for Critical Applications

From stormwater runoff to PFAS investigations, we deliver field-proven ISCO equipment and rental solutions across California, Nevada, and Hawaii. Our mission is simple: provide the tools you need to collect accurate, defensible data for compliance, research, and public health.

Stormwater Autosampler

Stormwater Monitoring

Storm events can carry heavy pollutant loads into local waterways. Our portable samplers and flow monitoring systems are designed to capture representative samples during rain events, ensuring compliance with NPDES permits and stormwater management plans.

flow-based autosampler

Industrial Pre-Treatment Compliance

Industrial facilities face strict discharge requirements to protect downstream treatment plants. Our refrigerated samplers preserve sample integrity for regulatory reporting, while flow meters provide the accuracy needed to document compliance with local pre-treatment ordinances.

PFAS autosampler

PFAS and Emerging Contaminants

PFAS (“forever chemicals”) present unique sampling challenges due to trace-level detection requirements. ISCO samplers—combined with proper tubing and preservation methods—are a trusted choice for reliable sample collection in environmental investigations.

Wastewater-Based Surveillance

Wastewater-Based Surveillance & Epidemiology

From COVID-19 monitoring to broader public health studies, wastewater-based surveillance has become a powerful tool for tracking community-level trends. Our automatic samplers and refrigerated units are ideal for continuous collection, supporting labs and agencies with representative samples for analysis.
