Abstract

There is a paucity of published data comparing methods of recovery for indigenous E. coli from sewage derived
sludges. The trials showed that E. coli recovery methods developed for drinking water analysis gave good and
consistent recovery of E. coli for a range of conventionally treated sewage matrices. These methods can therefore be
used reliably to assess the reduction of indigenous E. coli in treated sludges as required by current working
documents for the introduction of new sludge regulations
