This seems like it should be fairly simple, but I'm stumped. Using Rails I'm generating a hash with JSON HTTP Request. I'm using JSON.parse then looping through the response using an "each" (response.each do |river| do ... end) loop. My question is how can I get the siteName element only once? I'm returning duplicate data with incomplete results. The siteName element is listed twice in the JSON (see sample below). The other approach, not sure its the best, is to remove the entire hash in the array with a conditional looking for flow => 'n/a'. Does this make sense? What's the best practice \ solution in this situation? Any assistance is appreciated.

Here's the JSON I'm parsing: https://waterservices.usgs.gov/nwis/iv/?format=json&indent=on&sites=09358000,09359020,09359500,09361500,09362520,09363500&parameterCd=00060,00010&siteStatus=active
