Discerning Systems Inc.βs software portfolio is not a general-purpose developer toolkit, but a set of specialized desktop tools for environmental statistics, groundwater monitoring, and industrial/landfill data analysis. Its core products include DUMPStat, DUMPStat Explorer, CARStat, and the MIXOR/MIXREG/MIXNO/MIXPREG tools for mixed-effects regression modeling.
DUMPStat focuses on the analysis and management of detection monitoring data for landfills and industrial facilities. Explorer provides exploratory hydrogeochemical graphics such as Stiff Patterns, trilinear plots, multi-line time series, and XY scatter plots, with an emphasis on configurable output, live editing, and interactive results. CARStat extends these capabilities into compliance, assessment, and remediation scenarios, making it suitable for users who need to investigate data from industrial sites, disposal facilities, and brownfields. The MIX series covers mixed-effects regression for continuous, binary, ordinal, nominal, count, and survival-time data.
Its business model follows a traditional licensing approach. DUMPStat is licensed by facility site at USD 2500 per site, including 1 year of updates and technical support for 1 user; the consultant version costs USD 500. Explorer is USD 995 for a single-computer license and USD 1495 for a floating network license. CARStat costs USD 4000 per computer and can handle databases for unlimited sites. Annual technical support is USD 200 per person. The MIX series is described as being available for free download.
The main strengths are its clearly defined vertical use cases and its specialized charts and algorithms for groundwater, compliance monitoring, and environmental statistics. The site also clearly lists licensing, update, and support terms. The drawbacks are just as apparent: the website was last updated in 2017, and some download pages note that the current version cannot run natively on 64-bit Windows systems, although a separate 64-bit-compatible version is available by contacting the company. The main content does not mention APIs, SDKs, plugins, cloud deployment, or automation integrations, so support for modern developer workflows appears limited.
It is better suited to environmental consulting firms, municipal or regulatory agencies, environmental teams at industrial facilities, and professionals who need site-based groundwater statistical analysis. It is not a good fit as a general data science platform or developer integration component. Access from China, payment methods, and network availability are not disclosed in the main content, so they should be considered unknown. If programmability and low cost are priorities, alternatives such as the R and Python statistical ecosystems may be worth considering.
