State approvals for onsite residential systems
Studies and submittals for state approval of onsite residential wastewater treatment systems: the field data, the performance analysis, and the submission package.
Coming soonAnnual NPDES sampling for your ATU
Water data that gets your system approved.
Data storytelling, studies, and submittals for onsite residential wastewater systems, aquaponics, rain harvesting, and water reuse. Twenty five years focusing on the ecological function of “X” has taught me what regulators need to see.
What are you working on?
Pick one and the drops that matter light up. Or tap any drop to set x.

The problems I solve.
Six kinds of water project, one way of working: collect the data, find the answer, and put it in front of the people who decide.
Aquaponics
Water chemistry, data, and design support for closed-loop fish and plant systems, from classrooms to greenhouses.
Rain harvesting
Water quality studies for collecting, storing, and reusing rain, so you know what is in the tank before it goes to use.
Water resource and recycling management
Track what you draw, what you reuse, and what leaves the site, with data you can hand to a regulator.
Water quality analyses
Field and lab analyses of surface water, groundwater, wells, and treatment systems, interpreted in plain language.
NPDES, renewals, and other applications
Sample plans, field data, and the application package for NPDES permits, renewals, and other water science filings.
Raw data in. A clear answer out.
CEAV™
Say it like “sieve.” It sounds like one because it acts like one.
What you get.
Data storytelling
Infographics, white papers, and presentations that turn test results into a story a regulator, an owner, and an operator all follow.
Studies
Experimental design, test site setup, sampling protocols, and performance analysis, written up so the results stand on their own.
Submittals
Organized, version-controlled submission packages for state or third-party review, checked for format, content, and procedure.
Government relations liaison
One point of contact with local and state agencies: meetings, technical advisory sessions, hearings, and rule changes.
Coming soon
Annual NPDES sampling for your ATU.
Once a year, we collect your NPDES sample set, then run the results through Data CEAV™ so you can see how your aerobic treatment unit is really performing.
Annual NPDES sampling
One planned visit a year. Clean sample collection, lab testing, and a record that holds up for your permit.
Data CEAV™ of your ATU performance
Your results collected, entered, analyzed, and visualized, so a year of data becomes a clear picture of how your unit is doing.
The work, by the numbers.
Scopes from recent proposals. Client names stay private; the scale does not.

Onsite systems sampled across the seasons
Twelve in northeast Ohio and twelve in southwest Ohio, with summer and winter sample sets, to support a state recertification.
State approval20
Systems, six sample sets each
Effluent tested for CBOD5, TSS, ammonia, DO, and E. coli over ten months, then submitted for an NPDES renewal.

From fieldwork to report
A homeowner’s underperforming treatment unit: short site visits, data collection, and a visual report on what was wrong.

An aquaponics loop run by high schoolers
Donated design and training for a Northeast Ohio education center: nutrients and water cycle between growing beds and a fish farm.
