This toolkit supplies the documents that substitute for the regulator private well and septic owners do not have, and the ones that decide contamination claims. It provides an annual and periodic testing protocol keyed to what actually matters, a sampling and chain-of-custody instruction for use where litigation is contemplated, and a records request to the county health department and state agency that assembles the well log, septic permit, setback data, and complaint history in one filing. It includes transaction contingency language for water, septic, and raw-land soil evaluation, a septic inspection scope that specifies the hydraulic load test buyers rarely get, and a recorded shared well agreement term sheet. On the operator side it supplies a small system compliance calendar and a tiered public notification template. It closes with a contamination claim intake screen and authority tables.

The Water Quality, Well Permit, and Contamination Claim Toolkit

How to use these tools

⚠️ Well construction, septic permitting, transfer inspection requirements, and disclosure obligations are entirely state and local. The federal drinking water framework is uniform but is implemented by States with primacy, and state standards frequently exceed the federal floor. Conform every tool here to the governing jurisdiction.

Tools 1 through 3 are for well and septic owners. Tools 4 through 6 are for transactions. Tools 7 and 8 are for small system operators. Tools 9 and 10 are for claims.

Tool 1 — Private well testing protocol

[PROPERTY] — WELL TESTING RECORD Well permit no.: ______ Depth: ______ Casing depth: ______ Drilled: ______ Driller: ______

ANNUAL — every year, no exceptions

Date Total coliform E. coli Nitrate (mg/L) Lab Result kept?
☐

⚠️ Nitrate above the limit: do not give the water to infants under six months. This is an acute risk, not a chronic one.

EVERY 3–5 YEARS — local contaminants of concern (Ask the county health department or state geological survey what is common in your area.) ☐ Arsenic ☐ Uranium / gross alpha ☐ Radon ☐ Fluoride ☐ Manganese / iron ☐ Lead ☐ Sulfate ☐ pH / hardness ☐ PFAS ☐ Volatile organics (if fuel storage, dry cleaning, or industry is nearby) ☐ Pesticides (if agricultural)

AFTER ANY EVENT — test immediately ☐ Flooding of the wellhead or the yard ☐ Nearby drilling, blasting, or excavation ☐ A neighbor's septic failure ☐ A spill or fuel release ☐ Any change in taste, odor, color, or clarity ☐ Illness in the household ☐ New nearby land use

MAINTENANCE ☐ Wellhead cap sealed and vermin-proof ☐ Casing extends above grade ☐ Ground slopes away ☐ No cross-connections ☐ Abandoned wells on the property sealed by a licensed driller

SETBACK VERIFICATION (do this once, and after any neighboring construction) Distance to own septic tank ______ / drainfield ______ · Required: ______ Distance to each neighboring drainfield ______ · Required: ______ Distance to animal facilities ______ · fuel/chemical storage ______ · property line ______

Drafting notes. ⚠️ The annual test is the entire detection system for a private well — there is no standard, no regulator, and no notification, so an untested well produces no information of any kind. Bacteria and nitrate cost very little and catch the two most common and most acute problems.

The setback block deserves the emphasis it gets. A well can meet every setback on its own parcel and sit forty feet from a neighbor's drainfield, which is the fact pattern behind a large share of coliform contamination in older rural development — and it is discoverable in an afternoon at the county health department.

Keep every result. A dated series is the only baseline that will ever exist, and if a contamination claim later arises it is the difference between proving a change and asserting one.

Tool 2 — Health department and agency records request

PUBLIC RECORDS REQUEST To: [COUNTY HEALTH DEPARTMENT] · [STATE ENVIRONMENTAL / WATER RESOURCES AGENCY] Re: [PROPERTY ADDRESS / PARCEL ID] and surrounding area

As to the subject property: ☐ Well permit, well log, and driller's report ☐ Septic (onsite wastewater) permit, application, soil evaluation, and as-built drawing ☐ All inspection records, repair permits, and operating permits ☐ All complaints and enforcement records ☐ Any variance granted from setback or design requirements

As to surrounding properties within [1,000] feet: ☐ ⚠️ Septic permits and as-built drawings (to verify setbacks to the subject well) ☐ Well permits and logs ☐ Complaints, failures, and enforcement records

As to the area generally: ☐ Known contaminated sites, site assessments, and remediation files ☐ Discharge permits and monitoring reports for facilities within [1 mile] ☐ Underground storage tank records ☐ Any groundwater management area, wellhead protection area, or source water assessment covering this property ☐ Any sanitary survey or source water assessment for the serving public water system

If served by a public water system: ☐ Consumer confidence reports, last 5 years ☐ Violation and enforcement history ☐ Sampling results submitted to the agency, last 5 years

Format: electronic. Statutory response deadline: [__] days.

Drafting notes. ⚠️ The surrounding-properties block is the part people omit and the part that matters most. A well's setback compliance depends on neighboring septic systems, and those permits are public records at the same office. Requesting them costs nothing extra and answers a question the seller cannot.

In a contamination matter this request should precede discovery. The agency file is cheaper, faster, and establishes what was known and when — and it frequently identifies the source before a single deposition. See the public records checklist.

Tool 3 — Sampling and chain of custody

WHERE LITIGATION IS CONTEMPLATED, THE SAMPLING PROTOCOL WILL BE ATTACKED. DOCUMENT IT.

☐ Sampler: ☐ independent third party ☐ certified lab technician ☐ NOT a party ☐ Laboratory: certified for these analytes by ______ Certification no.: ______ ☐ Containers and preservatives supplied by the lab; used as instructed ☐ Sampling point: ______ (specify: wellhead / pressure tank / kitchen tap / after treatment / before treatment) ⚠️ Sample before and after any treatment device; results differ and the difference matters ☐ Purge protocol followed as the lab directs; purge volume and time recorded ☐ Field conditions recorded: date, time, weather, recent precipitation, pump run time, temperature ☐ Photographs of the sampling point and wellhead ☐ Duplicate and blank samples where the matter is contested ☐ Chain of custody form completed and signed at every transfer ☐ Hold times observed; delivery to the lab within the required period ☐ Original lab report retained with the chain of custody attached

Sample ID Location Date/time Collected by Analytes Relinquished to Date/time Received by

Drafting notes. The "not a party" line matters. A homeowner who samples their own well and sends it to a lab has produced a result the other side will attack on collection, handling, and hold time — and often successfully. ⚠️ The before-and-after-treatment point is the one most often missed: a whole-house filter can mask a source problem entirely, and a sample taken at the kitchen tap after treatment tells you about the filter rather than the aquifer.

Tool 4 — Transaction contingency language

WATER QUALITY CONTINGENCY

"This Agreement is contingent upon Buyer obtaining, at Buyer's expense within ___ days, a water sample collected by an independent party and analyzed by a laboratory certified for the analytes tested, showing results acceptable to Buyer in Buyer's sole discretion, for: total coliform bacteria, E. coli, nitrate, and [LOCAL CONTAMINANTS]. If results are unacceptable, Buyer may terminate and receive return of all deposits, or require Seller to remediate to Buyer's satisfaction before closing."

ONSITE WASTEWATER CONTINGENCY

"This Agreement is contingent upon Buyer obtaining, within ___ days, an inspection of the onsite wastewater system by a licensed inspector, which shall include: opening and evaluating the tank; measuring sludge and scum levels; evaluating baffles and the outlet filter; locating the drainfield and the reserve area; and performing a hydraulic load test of the drainfield. Seller shall provide access, the septic permit, the as-built drawing, and the pumping history. If the system is found to be failing or inadequate for the intended occupancy, Buyer may terminate or require repair or replacement before closing."

⚠️ RAW LAND — SOIL AND PERMIT CONTINGENCY

"This Agreement is contingent upon Buyer obtaining, within ___ days and at Buyer's expense, (a) a soil evaluation demonstrating soils suitable for an onsite wastewater system serving a ___-bedroom dwelling, including an adequate reserve area, and (b) an issued permit from [AUTHORITY] for such a system. If either is not obtained, Buyer may terminate and receive return of all deposits. Seller shall grant access for test pits and borings and shall restore no portion of the Property."

SETBACK AND DOCUMENTATION

"Seller shall deliver, within ___ days: the well permit and log; the onsite wastewater permit, soil evaluation, and as-built drawing; all inspection and repair records; the pumping history; and any recorded shared well agreement. Buyer's obligation to close is contingent upon Buyer's verification that the well meets all required setbacks from the subject property's and adjoining properties' onsite wastewater systems."

Drafting notes. ⚠️ The raw-land contingency requires an ISSUED PERMIT, not a favorable soil report. A soil evaluation that looks acceptable does not guarantee a permit — setbacks, reserve area, and design constraints can still defeat it. A buyer who terminates on soil results alone has taken a risk they did not need to take.

The hydraulic load test language is specified in detail because "septic inspection" without that specification routinely means someone looked at the tank lid. The distinction is between a system that appears intact and a system that can actually accept the flow a family will generate.

Tool 5 — Septic inspection scope

REQUIRED SCOPE — ONSITE WASTEWATER INSPECTION

Documentation review ☐ Permit, soil evaluation, and as-built drawing obtained from the health department ☐ Design flow / bedroom count vs. intended occupancy ☐ Repair, inspection, and pumping history

Tank ☐ Located and opened ☐ Material and condition ☐ Baffles/tees present and intact ☐ Outlet filter present and clean ☐ Sludge depth ______ Scum depth ______ ☐ Liquid level normal / high (high level indicates field problems) ☐ Signs of backflow from the field ☐ Lid safe and secure

Distribution ☐ Distribution box located and level ☐ Even flow to laterals ☐ Any standing effluent

Drainfield ☐ Located and mapped ☐ Surface condition — wet spots, odor, unusually vigorous growth ☐ Encroachments: vehicles, structures, paving, deep-rooted vegetation ☐ ⚠️ HYDRAULIC LOAD TEST performed — volume applied ______ gallons over ______ hours; result: ______ ☐ Reserve area located, confirmed available, and unencumbered

Mechanical components (advanced systems) ☐ Pump, floats, alarms functional ☐ Aerator / blower ☐ Maintenance contract in force ☐ Operating permit current ☐ Monitoring reports reviewed

Setbacks ☐ To subject well ______ ☐ To neighboring wells ______ ☐ To surface water ______ ☐ To property lines ______ ☐ To structures ______

Conclusion: ☐ Functioning ☐ Functioning with deficiencies ☐ Failing ☐ Inadequate for intended occupancy Estimated remaining life: ______ Recommended repairs: ______ Estimated cost: $______

Drafting notes. Two lines carry the value. ⚠️ The hydraulic load test distinguishes a system that looks fine from one that works under load — and it is omitted from most inspections unless the buyer specifies it. The reserve area confirmation determines what happens when the field eventually fails: a property with a clear reserve has a manageable future expense; one without has a problem that may have no affordable solution.

The "design flow vs. intended occupancy" line catches the common case of a three-bedroom system sold to a family of six.

Tool 6 — Shared well agreement term sheet

RECORDED SHARED WELL AGREEMENT — ESSENTIAL TERMS

☐ Parties and parcels — legal descriptions of every benefited and burdened parcel ☐ Ownership of the well, pump, pressure tank, and lines — tenancy in common, or ownership by one parcel with an easement to others ☐ Easement — recorded, for the wellhead, equipment, and lines, with access rights for maintenance ☐ Water rights — who holds them; whether a state permit is required and in whose name ☐ Allocation of costs — routine maintenance, electricity, testing, treatment, repair, and replacement of the well itself, with the formula stated ☐ Reserve fund for replacement, and how it is funded ☐ ⚠️ Testing — who tests, how often, which analytes, and an obligation to share results with all users ☐ Treatment — who decides, who pays, who maintains ☐ Usage limits — gallons per day, irrigation restrictions, and what happens if one parcel's use impairs another's supply ☐ Decision-making — unanimous, majority, or by shares; and what happens at deadlock ☐ Emergency repairs — authority to act unilaterally and to recover contribution ☐ Default — remedies where a party will not pay, including a lien against the defaulting parcel ☐ Dispute resolution — mediation, then arbitration ☐ Regulatory status — ⚠️ acknowledgment that if the system reaches fifteen connections or regularly serves twenty-five people it becomes a public water system under 42 U.S.C. § 300f, and who bears compliance costs ☐ Transfer — the agreement runs with the land and binds successors ☐ Termination — on connection to a public supply, or by unanimous consent

Drafting notes. ⚠️ Shared wells without a recorded agreement are among the most reliable sources of neighbor litigation in rural property, and the disputes are rarely about water quality — they are about who pays when the pump fails at eleven at night. The cost allocation formula and the emergency repair authority are the two clauses that prevent that.

The regulatory status line exists because a shared well that grows — a parcel subdivides, a second dwelling is added — can cross the public water system threshold without anyone noticing, at which point the compliance obligations in Tool 7 attach to a group of neighbors with no organization. See the neighbor disputes guide.

Tool 7 — Small system compliance calendar

[SYSTEM NAME] — PWS ID: ______ Category: ☐ Community ☐ NTNC ☐ Transient NC Connections: ______ Population served: ______ ⚠️ Fifteen connections OR twenty-five people regularly served = a public water system under 42 U.S.C. § 300f

Capital compliance planning: ⚠️ New treatment obligations — PFAS in particular — can exceed a small system's entire annual revenue. Evaluate state revolving fund financing and consolidation with a neighboring system.

Drafting notes. ⚠️ Assign each row to a position, not a person. These obligations persist across every change of association board, park manager, or school facilities director — and the single most common compliance failure is a system where the one person who understood the schedule left.

Tool 8 — Public notification templates

⚠️ TIER 1 — ACUTE — DELIVER WITHIN 24 HOURS

DRINKING WATER WARNING — [SYSTEM NAME] — [DATE] [BOIL YOUR WATER BEFORE USING / DO NOT DRINK]

What happened: On [DATE], [DESCRIBE: E. coli was detected / nitrate exceeded the standard / treatment failed]. What it means: [Plain-language health effects.] ⚠️ For nitrate: Do not give the water to infants under six months of age or use it to prepare infant formula. Consult a doctor if an infant shows blue skin or shortness of breath. What you should do: [Boil vigorously for one minute before drinking, cooking, or brushing teeth / use bottled water.] ☐ Do not rely on boiling for nitrate — boiling concentrates it. What we are doing: ______ Expected resolution: ______ Questions: [NAME, PHONE] · Please share this with anyone who drinks this water and may not receive it directly. Distributed by: ☐ radio/TV ☐ hand delivery ☐ posting ☐ telephone ☐ other: ______ Time distributed: ______

TIER 2 — 30 DAYS — repeat quarterly until resolved IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER "[SYSTEM] [exceeded the standard for ___ / failed to treat as required]. This is not an emergency. If it had been, you would have been notified within 24 hours." [Health effects language] [What is being done] [Contact]

TIER 3 — WITHIN 1 YEAR — may be included in the consumer confidence report "We are required to monitor your drinking water for ___ . During [PERIOD] we did not [complete monitoring / report results] and cannot assure the quality during that time. This is not an emergency."

Drafting notes. ⚠️ The nitrate boiling warning is the most important line in this tool. Boiling reduces microbial risk and concentrates nitrate, so the standard boil-water instruction is actively harmful for a nitrate exceedance — and the two notices must not be confused.

The "this is not an emergency" sentence is required in the lower tiers and does real work: a Tier 3 monitoring violation reads like an alarm to recipients, and the explanatory sentence is what prevents a paperwork failure from being received as a contamination event.

Tool 9 — Contamination claim intake screen

CLIENT: ______ PROPERTY: ______ CONTAMINANT: ______ DATE OF INTAKE: ______

1. EXPOSURE Sampling results: date ______ concentration ______ standard/limit ______ lab ______ Sampled by an independent party? ☐ Chain of custody? ☐ Before and after treatment? ☐ Duration of exposure: ______ Route: ☐ ingestion ☐ dermal ☐ inhalation Prior results establishing a baseline? ☐

2. SOURCE CANDIDATES ☐ Upgradient facility ______ ☐ Historic land use ______ ☐ Agricultural ______ ☐ Failing septic ______ ☐ Landfill ______ ☐ Fuel/UST ______ ☐ Firefighting foam site ______ ☐ Land-applied biosolids ______ Hydrogeologist retained? ☐ Groundwater flow direction established? ☐

3. AGENCY FILE (obtain before discovery — see Tool 2) ☐ Discharge permits and monitoring reports ☐ Site assessment / remediation files ☐ Health department complaints ☐ Consumer confidence reports ☐ UST records What was known, and when: ______

4. LIMITATIONS ⚠️ Earliest date claimant knew or should have known: ______ Applicable period: ______ Deadline: ______ (Accrual under the discovery rule is contested in nearly every contamination case.)

5. ⚠️ MEDICAL MONITORING — ANSWER BEFORE WORKING UP THE CASE Does this State recognize medical monitoring without present physical injury? ☐ Yes, standalone claim ☐ Only as a remedy attached to another tort ☐ No — present physical injury required If no and there is no present illness, the personal injury case may not exist.

6. FEDERAL CLAIMS — cleanup and injunctive relief, NOT damages ☐ 42 U.S.C. § 9607 response costs (definitions § 9601; framework 40 C.F.R. Part 300) — apportionment available on a reasonable basis, Burlington Northern & Santa Fe Railway Co. v. United States ☐ 42 U.S.C. § 6972 imminent and substantial endangerment (definitions § 6903; reach illustrated by City of Chicago v. Environmental Defense Fund) — 90-day notice ☐ 33 U.S.C. § 1365 — ⚠️ ongoing violations only, Gwaltney of Smithfield, Ltd. v. Chesapeake Bay Foundation, Inc. — 60-day notice ☐ 42 U.S.C. § 300j-8 against a system in violation — 60-day notice ⚠️ Do NOT plead implied federal damages — City of Milwaukee v. Illinois; Middlesex County Sewerage Authority v. National Sea Clammers Association

7. STATE CLAIMS — damages ☐ Nuisance ☐ Negligence ☐ Trespass ☐ Strict liability ☐ Products liability (manufacturer) ☐ State environmental statute with fee-shifting

8. DISCHARGE THEORY (if a source discharges to groundwater reaching surface water) ☐ Functional equivalent analysis under County of Maui v. Hawaii Wildlife Fund — transit time, distance, material traversed, dilution, manner of entry ☐ Prohibition 33 U.S.C. § 1311 · permit 33 U.S.C. § 1342 · 40 C.F.R. Part 122 · definitions 33 U.S.C. § 1362 ☐ ⚠️ Jurisdiction narrowed by Sackett v. Environmental Protection Agency — CHECK STATE LAW, which reaches further in many States ☐ Cross-program term interpretation: Environmental Defense v. Duke Energy Corp.

9. CAUSATION EXPERTS General causation expert identified? ☐ Specific causation? ☐ Hydrogeologist? ☐ ⚠️ Exclusion of a causation expert ends the case.

10. DAMAGES THEORY ☐ Property — diminution, connection cost, treatment systems, loss of use (easier to prove, easier to certify — consider leading with this) ☐ Personal injury ☐ Medical monitoring ☐ Response costs

Drafting notes. ⚠️ Items 4 and 5 come before items 6 through 10 for a reason — a limitations bar or a present-injury requirement can end the matter before any expert is retained, and both are answerable in an afternoon. Item 10's parenthetical is the most useful practical advice in the tool: property damage claims are frequently the sounder theory even where personal injury claims also exist, and they support class treatment far more readily. See the class action guide.

Sequencing the tools

Well owner, every year: Tool 1. Once, and after any neighboring construction: Tool 2's surrounding-properties block. Buying: Tools 2, 4, and 5. Shared well: Tool 6, recorded. Small system: Tools 7 and 8. Claim: Tools 3, 2, then 9 — in that order, because the sampling protocol and the agency file precede the legal analysis.

⚠️ Two items produce most of the value. Tool 1's annual bacteria and nitrate test is the only detection system a private well has. Tool 4's raw-land contingency — an issued permit, not a favorable soil report — prevents the single most consequential mistake in unsewered land purchase. Neither requires a lawyer; both are routinely skipped.
