SUNDAY, MARCH 13, 5 P.M. UPDATE: The boil water advisory for our Coatesville water system remains in place. Our water treatment plant has returned to normal operations, and we have collected water samples in our distribution system to confirm the water quality was not impacted and meets drinking w9ater standards. The results for those samples are pending but will be read early Monday morning. If the results are acceptable, the boil water advisory could be lifted shortly thereafter. We will notify affected customers through our alert system again when the advisory is lifted.

DO NOT DRINK THE WATER WITHOUT BOILING IT FIRST. Bring all water to a rolling boil, let it boil for one minute, and cool before using; or use bottled water. You should use boil or bottled water for drinking, making ice, washing dishes, brushing teeth and food preparation until further notice.
Inadequately treated water may contain disease-causing organisms. These organisms include bacteria, viruses and parasites, which can cause symptoms such as nausea, cramps, diarrhea and associated headaches.
These symptoms, however, are not caused only by organisms in drinking water, but also by other factors. If you experience any of these symptoms and they persist, you may want to seek medical advice.
Guardians of infants and young children and people at increased risk, such as pregnant women, some of the elderly, and people with severely compromised immune systems, should seek advice from their health care advisors about drinking this water. General guidelines on ways to lessen the risk of infection by microbes are available from EPA’s Safe Drinking Water Hotline at 1 (800) 426 4791.
