The Mann-Kendall (MK) trend test is a trusted way to evaluate groundwater contaminant concentration trends. EnSafe’s proprietary platform, LTMPro™, takes MK from a manual, spreadsheet-heavy exercise to a streamlined workflow that delivers defensible insights—fast.

Why LTMPro™?

For organizations managing remediation and long-term monitoring programs, time and clarity matter. LTMPro™ automates MK analyses, confidence testing, and first-order projections to estimate time-to-goal for wells with decreasing trends—helping teams move from raw data to actionable decisions with greater speed and consistency.

What’s new in LTMPro™ V2?

• Productivity gains via automated output generation, dramatically reducing project cycle time.
• Bulk data import from standardized Excel preprocessors—no more well-by-well data entry.
• Automated charts & tables—axes, formats, and decimals handled for clean, consistent deliverables.

Currently, we’re building out Version 3, which will feature full integration with EQuIS—the industry-standard platform EnSafe uses to store and manage environmental data. This integration will enable direct data access and seamless updates within LTMPro™, eliminating the need for manual transfers or preprocessors.

What does that mean for our clients?

• Accelerated reporting and reviews without sacrificing rigor.
• Consistent, auditor-ready outputs that support regulatory confidence.
• More time interpreting results and optimizing remedies, instead of formatting charts or wrangling spreadsheets.

How is LTMPro™ Different from Widely Available Tools?

LTMPro™ goes further than many Mann-Kendall programs, so you can make decisions, not just reports. For example:

• Actionable projections, not just trends. In addition to MK results, LTMPro™ generates first-order, time-to-goal projections calibrated to site data, helping estimate when concentrations are likely to meet cleanup targets.
• Publication-ready visual plots for every dataset. The platform automatically produces clean, consistent time-series plots (with remedial goal lines and projections) and formatted tables—client- and regulator-ready without manual tweaking.
• Richer statistics on each dataset. LTMPro goes beyond significance testing with a full set of metrics to support defensible decisions.
• End-to-end workflow automation. Bulk import, auto-formatted outputs, and site-wide batch processing reduce effort and variability across large portfolios—no coding or custom scripting required.
• Regulatory confidence, at speed. Consistent outputs paired with EnSafe’s review process help accelerate approvals while maintaining rigor.

The MK test is a non-parametric method that detects monotonic trends in time-series data—ideal for environmental datasets that can be skewed, irregular, or include non-detects. The test outputs (S statistic and p-value) indicate the direction of change and whether the trend is statistically significant. In practice, MK helps determine whether conditions are improving, worsening, or stable—informing remedy optimization and long-term monitoring strategy.
