From monitoring stations located below RIO GRANDE BELOW ANZALDUAS and still within HUC 13090002, select one representative station for Hidalgo County and one for Cameron County. First, screen candidate stations for each county within the specified area. Retain only stations whose detail page lists the type as River/Stream and that have records covering 2001–2010 for all four characteristic groups: Microbiological, Nutrient, Organics, Other, and Physical. If multiple stations in the same county qualify, select the station with the earliest year in which all four groups are simultaneously present. Then record the MonitoringLocationIdentifier of the selected station, the earliest year all four groups are simultaneously present, and the start year for each of Microbiological, Nutrient, Organics, Other, and Physical. Finally, output a single-line string in the order Hidalgo then Cameron: <County>:<MonitoringLocationIdentifier>|<common_start_year>|<Microbiological_start_year>|<Nutrient_start_year>|<Organics_Other_start_year>|<Physical_start_year>, with the two segments separated by a comma.", |
