For a U.S. water utility, my first choice would be LabWare, particularly its water/environmental offering. I’d put Thermo Fisher SampleManager and STARLIMS immediately behind it.
The important caveat is that “best” depends heavily on your utility’s size, number of samples, in-house vs. contract testing, drinking-water vs. wastewater scope, and how much automation you need.
My shortlist
| Rank | LIMS | Best fit | My take |
|---|
| 1 | LabWare | Medium/large water & wastewater utilities | Best overall for a dedicated utility laboratory |
| 2 | Thermo Fisher SampleManager | Large, highly automated labs | Excellent enterprise/instrument-integration choice |
| 3 | STARLIMS | Complex, highly regulated labs | Very capable and configurable |
| 4 | LabVantage | Utilities wanting broader lab informatics | Strong modern alternative |
| 5 | CloudLIMS / other SaaS LIMS | Smaller labs | Worth considering when speed and lower implementation burden matter |
1. LabWare — my first choice
LabWare stands out because it has a dedicated Water & Environmental LIMS, rather than simply adapting a generic LIMS to water testing. Its water workflow covers sampling schedules, sampling locations, chain of custody, testing, QC, regulatory-limit checking, review/approval, audit trails and reporting. It also supports field instruments, laboratory instruments, SCADA/historians and contract-lab data.
That is particularly relevant to a utility because you want the system to follow a sample from field collection → accessioning → analysis → QC → review → regulatory reporting, rather than having those activities scattered across spreadsheets, instrument software and separate databases.
LabWare also specifically cites water organizations including Orange County Sanitation District, Oklahoma City Water Utilities, Massachusetts Water Authority, Scottish Water and Sydney Water among its users.
2. Thermo Fisher Scientific SampleManager
I'd seriously evaluate SampleManager if you have a large laboratory, substantial instrument fleet, or significant enterprise-integration requirements.
Thermo specifically offers preconfigured capabilities for water and environmental testing, including sample scheduling and regulatory reporting, with consideration for ISO 17025 and NELAC requirements.
3. STARLIMS
STARLIMS is another strong enterprise option. Its environmental offering emphasizes full sample-lifecycle traceability, EPA methodologies, SOP-driven workflows, certifications and compliance.
I'd put it particularly high on the list if your laboratory does multiple types of environmental testing beyond routine drinking-water analysis.
What I would require in your RFP
For a water utility, I would make these must-have requirements, rather than evaluating LIMS primarily on generic features:
- Sampling-program management — locations, frequencies, analytes, containers, preservatives and schedules.
- Chain of custody — including field collection and custody transfers.
- Holding-time management — with automatic alerts/escalation.
- Drinking-water compliance — MCLs, action levels, method-specific requirements and state reporting.
- Wastewater/NPDES support, if applicable — including permit limits, calculations and DMR-related workflows.
- EPA/state electronic reporting and configurable electronic data deliverables.
- Instrument interfaces — especially ICP-MS, GC/MS, IC, TOC, microbiology and other instruments you actually operate.
- Field sampling/mobile capability — barcodes, GPS/location, field measurements and offline operation.
- QC management — blanks, spikes, duplicates, LCS/LCSD, calibrations, control charts and batch acceptance.
- Audit trail/e-signatures — particularly important for defensible regulatory records.
- Contract-lab management — electronic import and reconciliation of outside laboratory results.
- SCADA/historian integration where laboratory data needs to be correlated with treatment/process data.
- GIS integration — extremely useful for water-quality sampling locations.
- Flexible reporting/dashboarding without requiring developers for every new report.
- Data retention and retrieval sufficient for regulatory audits and historical investigations.
EPA's own water-quality guidance treats the LIMS as one component of a larger ecosystem alongside GIS, water-quality databases, SCADA and other systems, so I would evaluate integration architecture very heavily rather than buying a LIMS in isolation.
And for drinking water specifically, your LIMS should make it straightforward to produce the data needed by your state primacy agency/EPA workflows. EPA's Compliance Monitoring Data Portal is designed for electronic reporting by drinking-water utilities and laboratories.
My recommendation by utility size
Small municipal utility / relatively simple lab:
I'd look at a SaaS LIMS first. You probably don't want to spend millions implementing a highly customized enterprise platform.
Medium utility with an established in-house laboratory:
LabWare would be my starting point. Compare it directly with SampleManager and STARLIMS.
Large metropolitan utility / multiple laboratories / complex drinking + wastewater programs:
I'd run a formal RFP with LabWare, SampleManager and STARLIMS as the core shortlist. At this level, implementation architecture and integration capability can matter more than feature differences.
Very large or highly automated laboratory:
SampleManager becomes particularly compelling if instrument integration and broader enterprise systems are dominant requirements.
Bottom line
If you told me, “We are a municipal water utility and need one LIMS to manage drinking-water sampling, wastewater testing, compliance, field collection, instruments, QC and regulatory reporting,” I'd start with LabWare.
Its dedicated water/environmental configuration, water-utility references and coverage from sampling through reporting make it the strongest overall fit in my view.
If you give me (1) approximate population served, (2) number of samples/year, (3) drinking water vs. wastewater, (4) number of lab staff, (5) major instruments, and (6) whether you want cloud or on-prem, I can narrow this to a 2–3 vendor shortlist and give you a weighted LIMS evaluation/RFP scorecard tailored to your utility.
STARLIMS is another strong enterprise option. Its environmental offering emphasizes full sample-lifecycle traceability, EPA methodologies, SOP-driven workflows, certifications and compliance.
I'd put it particularly high on the list if your laboratory does multiple types of environmental testing beyond routine drinking-water analysis.
