Check the reported water sample against its stated parameter and comparison bounds.
Validation required
Fictional default example · 2025.
What the selected record shows. The supplied Ambient water pH for selected use result is 7.4 pH. Its stated comparison range is 6.5 to 8.5 pH. Within example comparison bounds.
Next step. Obtain the missing evidence listed below. Prepare evidence request in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
Method, use and sampling evidence are needed before a legal or health interpretation.
Compare the measured value only with matching parameter, unit, use and averaging period. Retain limit source/version and censored-result status.
Example bounds establish no compliance or diagnosis. Ambient, drinking-water, effluent, crop, food, air and noise standards are not interchangeable. A censored result is not an exact zero.
Other required records: Sample; parameter; concentration; unit; method; receiving-water use; effective limit.
Calculation appendix
Find gaps in confirmed environmental sampling coverage.
What the selected record shows. 30 river reaches are known to be uncovered; 5 have unknown coverage. 65% are confirmed covered.
Next step. Check the records behind the uncovered and unknown groups. Prepare coverage follow-up in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
Sample coverage does not establish environmental compliance.
100 × distinct covered eligible units / eligible frame. Known uncovered = frame − covered − unknown.
Count each eligible unit once for the selected service and period. Received messages, attendance, adoption and outcomes are separate measures. A single sample does not automatically cover a whole reach. Use the stated sampling schedule and matching assessment period.
Other required records: Monitoring network; required samples; accepted samples; dates; river segments.
Find missing evidence for recorded mitigation obligations.
What the selected record shows. The required evidence is incomplete for this mitigation compliance case. The items below identify what must be obtained or reconciled.
A filled checklist does not establish implementation or permit compliance.
Check each required item and retain its reference. A documented item is not a scientific, legal or institutional approval.
Evidence completeness alone cannot establish suitability, eligibility, safety, permission or method validity.
Other required records: Permit or approval; condition; due date; inspection; compliance evidence; owner.
Identify an unusual water observation for source and sampling checks.
What the selected record shows. Difference: -10 mg/L.
Next step. Check the unusual observation and its comparison basis. Prepare investigation brief in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
A deviation alone does not diagnose pollution or identify its source.
Later/comparison value minus Comparable reference value. Relative change = 100 × difference / Comparable reference value when the earlier value is positive.
Other required records: Comparable parameters; station; date; baseline; detection limits; laboratory method.
Check the records needed for a licence-application review.
What the selected record shows. The required evidence is incomplete for this environmental licensing case. The items below identify what must be obtained or reconciled.
The prototype does not issue an environmental licence.
Other required records: Activity classification; application; inspection; current rules; required documents; conditions.
Identify recorded licence expiry dates and unresolved review conditions.
What the selected record shows. Days until licence expiry: 14 days. Review expiry date and unresolved conditions.
Next step. Review expiry date and unresolved conditions; confirm the missing condition evidence. Prepare evidence request in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
Days until expiry do not grant renewal, extension or permission to operate.
Days until expiry = recorded expiry date − assessment date. Negative values mean the recorded expiry date has passed. Review unresolved conditions separately; no renewal or extension is granted.
Example due dates are not legal service standards. Do not alter statutory deadlines by silently subtracting pauses, or infer severity from age alone.
Other required records: License ID; expiry; application date; outstanding conditions; inspection status.
Check the evidence needed to refer a project through the applicable assessment pathway.
What the selected record shows. The required evidence is incomplete for this environmental assessment case. The items below identify what must be obtained or reconciled.
The responsible authority must determine the required assessment and permission.
Other required records: Project type; location; scale; sensitive areas; current criteria; authority.
Check the reported air observation against its stated averaging period and bounds.
What the selected record shows. The supplied PM2.5 concentration over stated averaging period result is 38 µg/m³. Its stated comparison range is 0 to 35 µg/m³. Outside example comparison bounds.
A sample comparison does not establish legal air-quality compliance.
Example bounds establish no compliance or diagnosis. Ambient, drinking-water, effluent, crop, food, air and noise standards are not interchangeable. A censored result is not an exact zero. Physical concentrations and magnitude measurements are non-negative. Signed raw instrument signals need laboratory interpretation; do not silently replace them with zero.
Other required records: Pollutant; averaging period; station; concentration; approved standard; quality flags.
Check the reported noise observation against its stated time and use conditions.
What the selected record shows. The supplied LAeq over stated interval and zone result is 62 dB(A). Its stated comparison range is 0 to 60 dB(A). Outside example comparison bounds.
A comparison does not establish a legal breach without the applicable standard and method.
Other required records: Complaint; time; location; land-use zone; measurement; applicable limit.
Check the source and evidence behind a reported effluent concern.
What the selected record shows. The required evidence is incomplete for this industrial effluent case. The items below identify what must be obtained or reconciled.
No pollution source, liability or safe discharge is determined.
Show the hazard, exposure and verified controls separately. No generic score, probability, diagnosis, site clearance or official warning is derived from a count.
Other required records: Facility; discharge; permit conditions; sample results; treatment controls; inspection.
Compare waste-management choices using permissions, capacity and adverse effects.
What the selected record shows. There is not enough information to choose this option. Obtain the records and evidence about conditions listed below. The supplied budget less cost is 300,000 LKR.
Next step. Obtain the missing records before choosing. Prepare evidence request in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
Cost does not establish lawful or environmentally suitable disposal.
Compare each alternative's stated benefit, adverse effects, domain evidence and mandatory constraints. Where cost and budget are supplied, budget balance = budget − option cost. A budget balance alone does not determine domain feasibility or select an option.
Other required records: Waste type; quantity; hazards; facilities; costs; environmental constraints.
Trace hazardous-waste records between the stated source and receiving records.
What the selected record shows. Broken or affected lineage: 1 items. Investigate linked downstream lot.
Next step. Investigate linked downstream lot. Prepare source comparison in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
A complete reference chain does not prove physical receipt or lawful handling.
Follow recorded upstream→downstream links within the same scope and period. Flag missing links; a confirmed defect identifies downstream linked candidates for authorized investigation.
Recorded lineage is not proof of product identity or recall authority. Preserve multi-source batches, transfers and versions; do not clear unlinked lots as safe.
Other required records: Waste manifest; generator; carrier authorization; quantity; receiving facility; acceptance.
Check reported activity overlap with the cited wetland record.
What the selected record shows. The supplied overlap is 18 ha within the 75 ha assessed footprint, or 24%. Check the cited boundary and source records before interpreting the overlap.
Next step. Check the matching footprint, source boundary and applicable conditions. Prepare overlap review in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
The figure does not establish an authoritative wetland boundary or permission.
100 × union of constraint overlap / proposal footprint. Count intersecting constraint areas once. The areas/counts are supplied records; this decision view does not calculate intersections, distances or locations.
Geometry preparation must use matching coordinate systems, dated boundary editions and valid spatial predicates. Overlap supports referral; it does not determine ownership, permission or site safety. A static reference image does not verify these supplied measurements or boundaries.
Other required records: Wetland extent; protection status; project footprints; edition; field evidence.
Identify pollution complaints past their recorded response date.
What the selected record shows. Open days past due: 29 days. Follow up overdue case.
Next step. Follow up overdue case; confirm the missing condition evidence. Prepare evidence request in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
Age alone does not establish severity or justify enforcement.
Open age = assessment date − received date. Days past due = max(0, assessment date − recorded due date) for open cases. Show documented critical conditions separately.
Other required records: Case ID; received date; impact evidence; due date; investigation; response.
Check inspection dates, resources and prerequisites.
What the selected record shows. Planned duration: 3 days. Resolve overlapping resource bookings.
Next step. Resolve overlapping resource bookings. Prepare schedule review in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
The example does not appoint inspectors or issue access authority.
Check start/end order, operating window, effort, predecessor completion and overlapping bookings for the same resource. A conflict is flagged; no optimal schedule is invented.
Other required records: Facility risks; permit conditions; previous findings; inspector capacity; due dates.
Check the evidence needed for an environmental-incident referral.
What the selected record shows. The required evidence is incomplete for this incident response case. The items below identify what must be obtained or reconciled.
A reported condition is not a final finding of harm or liability.
Other required records: Incident; pollutant; location; exposed receptors; current controls; response authority.
Identify groups without confirmed access to environmental guidance.
What the selected record shows. 30 facilities are known to be uncovered; 5 have unknown coverage. 65% are confirmed covered.
Distribution does not establish understanding or behaviour change.
Count each eligible unit once for the selected service and period. Received messages, attendance, adoption and outcomes are separate measures. Awareness coverage is not a finding of environmental compliance or behaviour change.
Other required records: Target institutions; findings; training participation; follow-up compliance; location.
Compare environmental observations before and after the stated intervention.
Verified published formula · Difference-in-differences arithmetic
What the selected record shows. Treatment change: 17; comparison change: 7; difference in changes: 10 mg/L. This comparison alone does not establish causation or benefit.
A difference in changes does not establish recovery caused by the intervention.
(Treatment after−before) − (comparison after−before), using the same outcome definition and periods.
The arithmetic alone does not establish causation. Design, parallel trends, confounding, attrition, uncertainty and adverse effects need appropriate evidence.
Other required records: Baseline quality; follow-up; reference sites; intervention dates; external pressures.

What the selected record shows. The required evidence is incomplete for this laboratory evidence case. The items below identify what must be obtained or reconciled.
Complete references do not replace laboratory quality assurance.
Other required records: Sample ID; custody; holding time; method; calibration; blanks; accreditation.
Compare environmental classification meanings across sources.
What the selected record shows. The required evidence is incomplete for this environmental records case. The items below identify what must be obtained or reconciled.
A matching label does not establish equivalent legal or scientific definitions.
