Look up your water system to see what it owes for initial monitoring and when the first sample has to be taken. Then ask us for lab options. It's free.
Community water systems and non-transient systems, such as schools and workplaces that run their own water. That's 66,415 active systems. Samples go to a certified lab using EPA Method 533 or 537.1.
Ask your state what it will accept. Results collected since January 1, 2019 with an approved method can count, and if you have some but not enough, you only sample to fill the missing periods. Your budget matters too: EPA's emerging contaminants grant for small and disadvantaged communities won't pay for these samples. The full guide to initial monitoring.
We aren't a lab. You tell us about your system, and we reply by email within 3 business days with certified labs that may fit. We won't give your details to a lab until you say so. You can also browse the lab directory yourself.
