What's in the report
1 · Property identity & summary
Address, APN, county, parcel reference. Water source type — private well, shared well, municipal, or unknown. A one-line plain-language status with its confidence. Key flags. The report date, version, and the source-coverage window. This is the page you forward.
2 · Well profile
Completion record if found: depth, casing, screened interval, construction date, driller. Proximity context — nearby wells and monitoring sites, basin and subbasin. Missing-data flags are printed, not omitted, so nobody mistakes silence for a clean record. Every field carries its source.
3 · Water quality
Recent test history where found: date, lab, analytes, result status. Recommended tests for the property type and region — nitrate, arsenic, coliform, salinity, and PFAS where relevant. An interpretation note that separates what is known from what is unknown and what needs retesting. Links to California testing resources and program eligibility.
4 · Groundwater context
Basin and subbasin. Local trend. Monitoring-site comparisons near the parcel with dates. Sustainability-plan threshold references where the plan publishes them. A plain statement of whether the local aquifer context is stable, declining, or mixed. This is the section that makes it due diligence rather than a records lookup.
5 · Transaction risk
Deal-impact summary for purchase, sale, refinance or rental. The questions a lender or buyer is likely to ask. Inspection and test urgency. An escrow checklist. Disclose-and-verify-before-closing reminders.
6 · Compliance triggers
Rental well-testing flag where AB 2454 or a local rule may apply. County-specific disclosure items. Documentation requirements for shared systems and storage. Notice that local rules add to state requirements — and a consult-counsel note on edge cases. Jurisdiction-aware, and modular by design.
7 · Recommended actions
A checklist, not a white paper. Order the right tests. Request the missing records. Add the disclosure language. Recheck if the timeline extends. Keep the packet for resale.
8 · Evidence appendix
A citation for every factual claim. A timestamped retrieval log. Data-freshness notes. The methodology summary and version. The trust layer that lets the report survive scrutiny.
How we label a fact
The report separates facts from interpretation, and it separates what a record says from how strongly it says it. Every material statement carries both a source status and a strength of support.
| Source status | Meaning |
|---|---|
| VERIFIED | Supported by records or documents |
| PARTIALLY VERIFIED | Some support exists, not enough to fully confirm |
| SELLER-REPORTED | Stated by the seller, not independently confirmed |
| CONTRADICTED | The statement conflicts with available records |
Paired with a confidence level — High · Moderate · Low · Very low. Where the record cannot support a finding at all, the report is flagged and not scored. False comfort and false alarm are equal defects.
"Confidence: High — the reported condition is supported by recent documentation and does not materially conflict with other records."
"Confidence: Moderate — the statement is plausible and partially supported, but independent verification is limited."
