As a single-source testing partner, depend on our personalized service to usher you through the complete scope of UCMR 4 required testing. A dedicated, hands-on point of contact will provide transparency to your shipping, testing and automated reporting needs.

Leveraging our expertise in chemical and microbiological testing of drinking water, Microbac has been accepted into the EPA’s laboratory approval process and is seeking approval for the complete set of required EPA methods to test all 30 contaminants.

Every 5 years the EPA identifies emerging water contaminants to be monitored by all large public water systems (> 10,000 customers) and a representative set of small water systems. The study’s results provide input for future regulatory requirements to ensure the safety of our public drinking water.

Microbac’s UCMR 4 analysis kit is custom designed for complete, convenient EPA-required testing. Sample bottles will be sent to you pre-labeled and our simple 5-step process ensures ideal service and ease to keep you in compliance.
