This is a sample published CCR showing what 1water.ai actually ships. The numbers below are illustrative and tagged Demo — they do not represent real 2025 water quality data for any specific utility.
The water we delivered to our community in 2025 met every federal Maximum Contaminant Level under 40 CFR 141. This report summarizes the detected contaminants, our sources, and the steps we take to keep your water safe.
Our system is supplied primarily from groundwater sources in the Silurian aquifer. Peak summer demand is supplemented by purchased water from a regional authority.
Water supplied by three groundwater wells in the Silurian aquifer plus purchased water from the St. Joseph River regional authority during peak summer demand.
A source water assessment is available on request. Contact the utility at .
The table below lists every regulated contaminant detected in our system during 2025 with the federal MCL (Maximum Contaminant Level) and MCLG (Maximum Contaminant Level Goal) as defined in 40 CFR 141 Appendix A.
| Contaminant | MCL / AL | MCLG | Level detected | Range | Sampled | Likely source |
|---|---|---|---|---|---|---|
| Arsenic | 10 ppb | 0 ppb | 3.2 | 1.8 – 4.5 | 2025-06-10 | Erosion of natural deposits; runoff from orchards |
| Barium | 2 ppm | 2 ppm | 0.08 | 0.05 – 0.11 | 2025-06-10 | Discharge of drilling wastes; erosion of natural deposits |
| Chromium | 100 ppb | 100 ppb | 4.1 | 2.0 – 6.8 | 2025-06-10 | Erosion of natural deposits; steel and pulp mills discharge |
| Copper | 1.3 ppm AL | 1.3 ppm | 0.31 | 0.08 – 0.62 | 2025-05-01 | Corrosion of household plumbing; natural deposits |
| Fluoride | 4.0 ppm | 4.0 ppm | 0.8 | 0.6 – 1.0 | 2025-04-15 | Erosion of natural deposits; water additive for dental health |
| Lead | 15 ppb AL | 0 ppb | 12.5 | 0.8 – 14.1 | 2025-05-01 | Corrosion of household plumbing; erosion of natural deposits |
| Nitrate (as N) | 10 ppm | 10 ppm | 2.1 | 1.0 – 3.4 | 2025-06-10 | Runoff from fertilizer use; erosion of natural deposits |
| TTHM | 80 ppb | — | 28.4 | 16.1 – 42.7 | 2025-09-20 | By-product of drinking water chlorination |
| HAA5 |
Our 90th-percentile lead value for the 2025 compliance period was 12.5 ppb, below the federal Action Level of 15 ppb.
If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. Orange City Water is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking.
Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline or at www.epa.gov/safewater/lead.
No Maximum Contaminant Level violations, treatment technique violations, or monitoring violations occurred during the 2025 reporting period.
Some people may be more vulnerable to contaminants in drinking water than the general population. Immunocompromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (800-426-4791).

This Consumer Confidence Report is required under 40 CFR 141 Subpart O (the federal Safe Drinking Water Act rule) and is published annually by every Community Water System in the United States. It covers the 2025 calendar year. The complete federal rule and the full definitions of MCL, MCLG, AL, Treatment Technique, ppm, and ppb are available from the U.S. EPA at ecfr.gov (40 CFR 141 Subpart O).
This report was drafted and published through 1water.ai. The federal rule text it validates against was fetched verbatim from the eCFR JSON API and is retained with this report per 40 CFR § 141.155 for a minimum of five years.
