Steps

  1. Build a bounding-box or site-based query against the WQP Result search service with characteristicName set to Nitrate, E. coli, or Fecal Coliform and a lat/long bounding box around the property.
  2. Request mimeType=csv for direct tabular output suitable for spreadsheet review.
  3. Use the Station search endpoint first to confirm which nearby monitoring stations exist before pulling results.
  4. Filter by startDateLo/startDateHi to compare readings before and after a suspected septic failure event.
  5. Note the provider field (NWIS vs WQX) returned per result since query syntax nuances differ slightly by contributing source system.
