Higher than normal levels of fecal matter in the Pottstown water supply forced water officials to dump reserves, after the tank was discovered to be contaminated.
The Mercury reports the tank reserves were contaminated with fecal coliform, which led to the decision to dump the reserves.
Water in the area is safe to drink, however, officials had to send out an alert to residents to conserve water this morning until the borough can replenish some of its reserves.
The order was lifted, however, just before 9 a.m.
According to The Mercury, heavy rains led to the contamination being higher than normal as they entered the plant.
Officials stress drinking water in the area is safe to consume.
