Brief Summary:
Approximately 40 million people in the US are served by private wells, many of which are untreated. The investigators estimate that 1.29 million cases of gastrointestinal illness (GI) per year are attributed to consuming water from untreated private wells in the US. These cases of GI can cause a significant burden in terms of health care costs and lost work/school days, as well as increased risk to developing longer term health complications. This impact is magnified when accounting for vulnerable populations such as children under the age of 5, the elderly and the immunocompromised. The investigators are preparing to conduct the first household randomized controlled trial (RCT) to investigate whether consuming well water treated by ultraviolet light (UV) compared to consuming untreated private well water decreases the incidence of self-reported gastrointestinal illness and respiratory infections in children under 5. The investigators will collect illness symptom data using a combination of weekly text messages and online illness questionnaires.

Arm Intervention/treatment
Active Comparator: Active UV Device
A household water treatment device with a lamp emitting germicidal UV. The device will be operated at 50 millijoule per square centimeter to treat >99.9% of all bacteria, protozoa, and most viruses in water supplies.
Device: Active household UV water treatment device
This point-of-entry treatment device will use germicidal UV to treat all of the well water used in the home.

Sham Comparator: Inactive UV Device
A device that appears identical to the active comparator device except the lamp will not emit germicidal UV.
Device: Inactive household UV water treatment device
This sham device will use a lamp not emitting germicidal UV.

Primary Outcome Measures :
  1. Incident gastrointestinal illness [ Time Frame: 12 months ]
    The investigators will collect data on the presence of gastrointestinal illness symptoms through weekly text messages. Households that report symptoms through text messages will be directed to an online illness questionnaire to characterize the symptoms (incidence, severity, duration, diarrhea, vomiting, coughing, etc.), febrile episodes, as well as relevant exposure information such as recent travel, exposure to ill persons, etc. Incident gastrointestinal illness (GI) is defined by the reporting of a minimum of three episodes of diarrhea or vomiting in a 24 hour period. Each illness will be considered distinct when separated by ≥ 6 symptom-free days.
