USGS · Texas groundwater chloride, arsenic and nitrate/nitrite chemistry

U.S. Geological Survey, NWIS records retrieved through the USGS/EPA Water Quality Portal; indicate normalization changes.

Historical WQX 2.2 NWIS response for Texas groundwater chemistry. This profile excludes USGS additions after March 11, 2024; requested date bounds do not establish actual coverage. Concentration fractions, analytical methods, detection conditions, quantitation limits, qualifiers and QC samples must be reviewed before training. Non-detects are null, not zero or the quantitation limit. Source agency/site/activity identifiers do not reconcile physical wells. Acquisition is not historical availability. Source clock time and timezone code are retained without inventing a UTC instant.
