Following the initial survey in 1991, a follow-up Phase 2 was conducted that focused on the Newark 

 Bay area. Sediment samples were collected at 57 randomly chosen stations. The study area was di- 

 vided into strata that were approximately equal in size such that the data from each sample would have 

 approximately equal spatial weight. Station location coordinates were chosen randomly within each 

 stratum with the aid of EPA's EMAP software and hardware. Locations of the stations within the 

 Passaic River, Hackensack River, Newark Bay, Kill van Kull, and Arthur Kill are listed in Table 5. 

 Unlike Phase 1, the samples collected during Phase 2 were not replicated in the field; that is, only one 

 sample was collected at each station. However, unlike Phase 1 , the station locations were selected with 

 a totally random approach.
