Satsuma Water & Sewer
Quality & Service at the highest level
The Water and Sewer Board of the City of Satsuma
PWS ID: AL0001022
About Your Water System
This report summarizes the quality of drinking water delivered during 2025 and the Board's efforts to provide a safe, dependable supply. Water was supplied by two groundwater wells drawing from the Alluvial Sand of the Quaternary Age Aquifer.
Well No. 1 is on Plateau Avenue, Well No. 3 is on Woodland Avenue and Seventh Street. Chlorine is used for disinfection, lime raises pH and reduces corrosivity, and zinc orthosphate may be used for corrosion control.
The system serves approximately 2,579 customers, has two storage tanks with a combined capacity of 950,000 gallons, and can receive emergency water from Saraland.
Source-Water Assessment and Public Participation
ADEM approved a Source Water Assessment identifying potential contamination sources and evaluating source susceptibility. More than 75% of the potential sources identified in the assessment areas were reported in the non-susceptible or medium-risk categories.
The assessment is available for review at the Water and Sewer office. Protect source water by following pesticide and herbicide labels and properly disposing of household chemicals, paints, and used oil.

Monitoring note: Unless otherwise indicated, the tables use results from January 1 through December 31, 2025. Some contaminants are monitored less often than annually because concentrations are not expected to change significantly. Statewide waivers applied to asbestos and dioxin.
All drinking water, including bottled water, may reasonably be expected to contain small amounts of contaminants.
General Information
Drinking-water sources include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water moves over or through the ground, it can dissolve minerals and radioactive material and pick up substances from animals or human activity. EPA regulates public tap water; FDA regulates bottled water.
Contaminant Categories
Microbial contaminants include viruses and bacteria; inorganic contaminants include salts and metals; pesticides and herbicides may result from agricultural and residential uses; organic chemicals may result from industrial processes, petroleum, runoff, and septic systems; radioactive contaminants may occur naturally or resultfrom mining and oil and gas activities.
People at Increased Risk
People receiving chemotherapy, organ-transplant recipients, people with HIV/AIDS or other immune-system disorders, some older adults, and infants may be more vulnerable to infection. They should seek advice from health-care providers. Call EPA's Safe Drinking Water Hotline at 800-426-4791.
Revised Total Coliform Rule
Total coliform is an indicator of distribution-system integrity and is addressed through a treatment technique. Positive samples may require repeats and Level 1 or Level 2 assessments; E. coli is evaluated under a separate MCL. The original 2024 raw-water result is retained on Page 3 as source-water information, not 2025 distribution compliance data.
Lead, Copper, and Corrosion Control
Exposure to lead can cause serious health effects in all age groups. Infants and children may have decreases in IQ and attention span and new or worsened learning and behavior problems. Exposure before or during pregnancy can increase these risks. Adults may have increased risks of heart disease, high blood pressure, kidney problems, or nervous-system problems.
Use cold water and flush stagnant taps before drinking or cooking; boiling does not remove lead. Lime is used to adjust pH, and zinc orthophosphate may be used for corrosion control.
Service-Line Inventory and Schools
A service-line inventory has been prepared. Contact the Water and Sewer office at (251) 675-1257 to review it or obtain access instructions. The system samples for lead in schools and licensed child-care facilities as required or requested; contact the facility for its results.
2025 PFAS Monitoring Results - Plant No. 1 & No. 2
PFAS are manufactured chemicals that persist in the environment. The table retains all original PFAS analytes and corrects the federal reference values. The 2025 results are informational; official compliance calculations may use running annual averages and specified treatment-point data.

| Hazard Index mixture | Components ND | Unitless | 1.0 | 1.0 | PFHxS, PFNA, HFPO-DA, and PFBS mixture |
* PFBS has no individual MCL; it is a component of the PFAS Hazard Index.
† Three PFOS samples were reported as 0.0000019 mg/L, non-detect, and 0.0000021 mg/L. Treating the non-detect as zero for the stated arithmetic summary gives 0.00000133 mg/L (1.33 ppt); a non-detect is not a measured zero.
Table of Detected Contaminants and Water-Quality Constituents
All original detected-table data are retained below. Regulated contaminants now show the applicable goal/standard and compliance metric; individual trihalomethane compounds are identified as supplemental components rather than being assigned the 80-ppb TTHM standard.

† The 5-pCi/L standard applies to combined radium-226/228; the laboratory data provided identify Radium-228 only.
Lead and copper were sampled at two taps; lead was not detected at the 1-ppb reporting limit.
UR = unregulated; PDWS = primary drinking-water standard; SDWS/SMCL = secondary drinking-water standard/level; N/A = no individual standard assigned. pCi/L = picocuries per liter; mL = milliliter.

* The 2025 laboratory reports provided for review identify Radium-228 results of 0.322 and 0.477 pCi/L. The official combined radium-226/228 compliance result should be confirmed with ADEM.
† The 1.65-1.78 ppm chlorine values are July 2025 field measurements from the DBP sampling report; substitute the official 2025 annual average and full distribution-system range when available.
Waived = statewide waiver. ND = not detected at or above the reporting limit. Some values may be from a prior approved sampling cycle when annual monitoring was not required.
