| 01 | | THE FAILURE MODE |
| |
| The difference from a regulated system is procedural, not chemical. A community water system samples on a schedule, reports results and must notify customers when a standard is exceeded. A private well owner is the operator, the laboratory client and the regulator, and no third party is required to tell them anything [1]. |
| What is in the water is mostly not detectable without a test. Contaminants from geologic sources, primarily manganese, arsenic and radon, accounted for about 80 percent of the concentrations that exceeded a human-health benchmark [3]. Nitrate, which exceeded its benchmark in about 4 percent of wells sampled, was the only constituent from manmade sources above 1 percent [3]. None of these announce themselves by taste, odour or appearance. |
| The supply itself has a second dependency. Water from a domestic well arrives through an electrically driven pump, so the same outage that takes the lights takes the water, and a household on a private well has no utility to call about either. |

| 02 | | YOUR END / THEIR END |
| |
YOUR END HOUSEHOLD The response is measurement, and it is cheap relative to what it resolves. Vernon County, Wisconsin, publishes its public health department's fee schedule: nitrate $30, arsenic $37, lead $37, prices updated in January 2026 [5]. The department notes that 40 percent of Wisconsin residents draw drinking water from private wells [5]. An annual bacteria and nitrate check with a one-time metals panel sits in the low hundreds of dollars, against a supply the household already owns outright. What testing does not do is fix anything. It converts an unknown into a number on a specific date, and the number applies to that date: seasonal and aquifer conditions change, so the test has to repeat to stay useful. A result above a benchmark then opens a separate and larger capital decision about treatment, which the test does not pay for. USGS is also explicit that concentrations above a benchmark do not necessarily mean adverse effects are occurring [4]. COST / FUNCTION / LIMITS |

THEIR END COMPANY-REPORTED Franklin Electric (NASDAQ: FELE) makes the submersible motors and pumps that lift water out of those wells. Its Water Systems segment reported net sales of $358.5 million in the second quarter of 2026, up 5 percent, with segment operating income of $65.2 million, up 6 percent [6]. Within the United States, sales of groundwater pumping equipment rose 12 percent in the quarter and water treatment products 14 percent [7]. The counterweight is where the growth came from. The segment increase was attributed to price realisation, currency and the incremental impact of recent acquisitions [7], and management described consolidated growth of 6 percent as balanced between organic and inorganic contributions [6]. A pump is replaced when it fails or when a house is built, which is a mechanical cycle rather than a response to any water-quality statistic. POSITION / CAPACITY / RISK |

| 03 | | THE ALERT |
| |
| The U.S. Geological Survey reports that about 37 percent of U.S. domestic supply wells, and about 45 percent of public-supply wells, have lithium concentrations that could present a potential human-health risk [1]. Lithium sits outside the set of contaminants most well owners test for, which is the general shape of the problem: the list of things worth measuring is set by whoever last read the research. |
| |
| 04 | | THE TWO DECISIONS |
| |
| The household decision is a few hundred dollars of laboratory work on an asset that supplies everything the house drinks, where the alternative is continuing to assume a result rather than hold one. The exposure decision is a pump manufacturer whose volumes are set by construction and replacement cycles rather than by what the sampling finds. The premise weakens materially if state programmes expand subsidised testing to the point where the household cost falls toward zero, as some already have, or if a later USGS assessment finds exceedance rates materially below the one-in-five figure that has held across two separate studies. |

More than 43 million people, about 15 percent of the U.S. population, rely on domestic (private) wells as their source of drinking water; the quality and safety of water from domestic wells is not regulated by the Federal Safe Drinking Water Act or, in most cases, by state laws; a USGS study reports that about 45 percent of public-supply wells and about 37 percent of U.S. domestic supply wells have lithium concentrations that could present a potential human-health risk.

Around 15 percent of the U.S. population, over 43 million people, rely on private wells as their source of drinking water; a USGS study of 2,100 private wells found that water pumped from about one in five wells contained one or more contaminants at a concentration greater than a human-health benchmark for drinking water; EPA estimates that more than 23 million households rely on private wells for drinking water.

| [3] | U.S. Geological Survey. "The Quality of the Nation's Groundwater," featured story. Water quality assessed in untreated water from 6,600 wells in regional aquifers supplying most of the groundwater pumped for drinking water; more than one in five (22 percent) groundwater samples contained at least one contaminant at a concentration of potential concern for human health; contaminants from geologic sources, primarily manganese, arsenic and radon, accounted for about 80 percent of concentrations exceeding a human-health benchmark; nitrate exceeded its benchmark in about 4 percent of wells sampled and was the only constituent from manmade sources exceeding its benchmark in more than 1 percent of samples.

| [4] | U.S. Geological Survey. "Water-Quality Benchmarks for Contaminants," Water Resources Mission Area. Concentrations that exceed a benchmark do not necessarily indicate that adverse effects are occurring; more than 43 million people, about 15 percent of the U.S. population, rely on domestic wells whose quality and safety are not regulated by the Federal Safe Drinking Water Act or, in most cases, by state laws.

| [5] | Vernon County, Wisconsin, Public Health Department. "Water Testing for Private Wells." Published fees of $30 for nitrate, $37 for arsenic and $37 for lead, with prices noted as updated 1/01/2026; states that 40 percent of Wisconsin residents get their drinking water from private wells; recommends testing for arsenic at least once and more frequently if arsenic is found.
