Are there differences between facilities listed in EnviroFacts versus those in ECHO?
Generally, the data within the two systems will be very similar, though some slight differences may be apparent if similar queries are run. These differences are normally attributed to: situations in which EnviroFacts has posted an update that has not yet been captured by ECHO s monthly refresh process, or differences attributed to a different set of data systems that are queried in ECHO versus EnviroFacts (for example, a query to EnviroFacts may include Safe Drinking Water Act sources, which are not included in the ECHO site).
