TL;DR: On August 28, 2026, WAPA issued a Tier 1 Boil Water Advisory for St. Croix after E. coli was found twice at Frederiksted Dock Sample Point 327 — boil tap water for one minute or use bottled water for drinking, ice, teeth, food and dishes until officials lift the order.
Advisory Issued For Frederiksted Dock Sampling Point
The Virgin Islands Water and Power Authority announced a Tier 1 Public Notification and Boil Water Advisory on August 28, 2026, in St. Croix, U.S. Virgin Islands, according to the official notice titled WAPA ISSUES BOIL WATER ADVISORY FOLLOWING DETECTION OF E. COLI.
The trigger was bacteriological sampling in the potable distribution network. Drinking-water specimens taken from Sample Point 327 at Frederiksted Dock contained E. coli, prompting precautionary action to safeguard health.
WAPA instructed customers not to consume tap water without prior boiling. Water meant for human ingestion or close-contact household tasks should reach a full boil for one minute, then cool before use. Bottled water was identified as an acceptable substitute while the notice remains active.
The utility emphasized that the order stays in force until further notice. Residents should keep boiling or switch to bottled supplies until WAPA publicly announces that testing supports lifting the advisory.

What Testing Found On August 24, 26 And 28
A routine specimen gathered on August 24, 2026, at Sample Point 327 tested positive for both Total Coliform and E. coli.
Repeat sampling on August 26 again returned positive findings for Total Coliform and E. coli at that same Frederiksted Dock location.
On that same August 26 round, two companion sites returned different outcomes. The designated upstream point, Sample Point 052 at Hannah's Rest, showed no Total Coliform and no E. coli. The downstream point, Sample Point 077 at Frederiksted Ballpark, also showed no Total Coliform and no E. coli.
WAPA crews collected another set of specimens from all three points on August 28. At the time of the announcement, laboratory outcomes for that third round were still pending.
Because the organism appeared in both the initial routine specimen and the repeat specimen at Sample Point 327, the Authority said it moved to Tier 1 notification as a protective step.
How To Use Water Safely Until The Order Lifts
The advisory directs households to use boiled or bottled water for five categories of use:
- drinking
- ice production
- tooth brushing
- meal and drink preparation
- dish washing
Tap water should not be swallowed unless it has first boiled for one minute or has been replaced entirely by bottled product.
For emergency planners, the instruction is straightforward: treat every cup, pot, pitcher and tray in the affected zone as requiring either a one-minute boil plus cooling time or a bottled source. That includes water used to rinse produce, mix beverages, make infant preparations where applicable in household meal routines, and clean eating utensils.
Store a cooled supply in clean, covered containers after boiling to avoid recontamination during storage. Keep bottled reserves separate from untreated tap supplies and label them clearly if multiple household members draw water.
The utility also clarified what this event is not. According to the August 28 notice, the advisory is not connected with the separate wastewater matter handled by the Virgin Islands Waste Management Authority in Christiansted.
Why Low Pressure Raises Contamination Risk
WAPA linked the Frederiksted finding to hydraulic conditions in that part of the island network.
Low pressure in the Frederiksted zone can allow outside material to move into pipes where openings exist, the Authority explained. Leaks, breaks and other vulnerable spots become more significant when internal pressure drops.
Investigators were examining distribution conditions, including chlorine residuals described as low or absent in the affected vicinity. Additional sampling was underway to identify the origin of the bacteriological signal.
That examination dovetails with broader system strain described one day earlier in a second WAPA update titled WAPA Provides Update on Intermittent Water Service on St. Croix. That August 27, 2026, statement said portions of the St. Croix potable network had delivered inconsistent service for the prior week, while other customers had faced intermittency since early summer.
The interconnected layout means trouble upstream travels downstream. Water generated at Richmond moves through pipes, pumps, tanks and related assets to communities island-wide. A disruption or surge in demand near the start of that chain can reduce availability much farther along, including in Frederiksted.
Drought, Demand And An Aging Pipe Network
St. Croix was confronting Level 3, or Extreme Drought, based on information from the Virgin Islands Territorial Emergency Management Agency and NOAA cited in the August 27 system update. A period normally wetter during hurricane season had instead behaved like a prolonged dry season.
As rooftop cisterns emptied, more households shifted to the public potable network. That shift lifted demand while the distribution grid was already stressed.
Seven Seas Water Group, operator of the reverse-osmosis production plant, had raised output through the extended dry spell. WAPA said the constraint was not only manufacturing water but conveying it through older lines fast enough to satisfy need without triggering further failures.
Crews in recent days had addressed major leaks at Kingshill near Alfredo Andrews School, at Estate Mountain and Mt. Pleasant, and in the Harbor View and Princesse vicinity. Repairs at Kingshill finished Friday afternoon, an initial Mt. Pleasant fix finished Friday morning, a second Mt. Pleasant leak found later was fixed Saturday, and Harbor View work also finished Saturday. Improvement spread to nearby neighborhoods within hours, with more customers regaining service Sunday and Monday, though higher-elevation streets waited until Tuesday in some cases.
Progress then reversed when another leak emerged at Catherine's Rest. That loss drew down Kingshill storage-tank reserves and erased much of the regained ground. As tank levels declined again, gravity-fed service zones experienced weak flow or no flow.
Older infrastructure compounds the cycle. Forcing larger volumes through fragile segments under unusually heavy demand can elevate pressure and encourage new breaks, the utility said. Operators were therefore regulating the network day by day, including changes to water-hauler hours intended to keep pressure steadier leaving the pump station that discharges directly into distribution piping.
Health Effects Linked To E. Coli In Drinking Water
The presence of E. coli in treated drinking water signals possible contact with human or animal waste, according to the August 28 health section. That type of intrusion can carry organisms capable of causing illness.
Reported symptoms after drinking contaminated water can include loose stools, stomach cramps, nausea, headache and other gut-related sickness.
Risk is not uniform. Babies, small children, seniors and individuals with severely weakened defenses face higher likelihood of serious disease.
WAPA advised anyone with lingering symptoms to pursue medical guidance. People already facing elevated health risks were urged to ask their own clinicians about water use while the advisory continues.
No lift date was given. The Boil Water Advisory will persist until repeat laboratory work shows the bacteriological issue is gone and WAPA, together with the Virgin Islands Department of Planning and Natural Resources, agrees the order can end. Monitoring and corrective work will proceed until that threshold is met.
Utility Corrective Steps And Coordination
WAPA said it had started corrective measures and expanded surveillance after the positive results.
Listed actions included further bacteriological collection, assessment of chlorine residuals in the impacted area, targeted flushing where suitable, review of pipe-network conditions, and coordination with the Department of Planning and Natural Resources, identified by the acronym DPNR.
The Authority pledged continued observation and remediation until resolution.
For households building readiness plans, the operational lesson is to maintain independent reserves before advisories arrive. Keep bottled inventory, a heat source and fuel for a one-minute boil, clean storage vessels, and contact numbers for utility updates. During pressure-loss episodes, reduce high-volume draws. WAPA specifically asked customers to avoid filling a cistern by hose or using large quantities at once, noting that such draws can depress pressure farther along the system and delay Kingshill tank recovery.
Residents can help locate hidden losses by watching for pooled water on roads, unexplained flowing water, or unusually lush or soaked grass, then reporting outages or suspected breaks to www.viwapa.vi or 340-773-2250 ext. 3065 Monday through Friday from 8 AM to 4 PM, as described in the August 27 service update.
