During 2013-2017, the U.S. Geological Survey, National Water-Quality Assessment (NAWQA) Project, collected water samples year-round from the National Water Quality Network – Rivers and Streams (NWQN) and reported on 221 pesticides at 72 sites across the US in agricultural, developed, and mixed land use watersheds. Pesticide Toxicity Index (PTI) scores, a screening-level tool that uses an additive, toxic-unit model, were calculated to estimate the potential chronic and acute toxicity to 3 taxonomic groups – fish, cladocerans, and benthic invertebrates. The pesticide that makes the single largest (maximum) contribution to the PTI is called TUmax. This dataset consists of the PTI and TUmax scores, as well as, the TUmax pesticide names, types, and parent/degradate designations for fish, cladocerans, and benthic invertebrates in each sample.
Data were calculated to estimate the potential chronic and acute toxicity to 3 taxonomic groups – fish, cladocerans, and benthic invertebrates at the National Water Quality Network sites during 2013-2017.

For this analysis, concentrations were considered detections if the result was above the reporting level or between the method detection level and reporting level. Results were considered non-detections if the result was below the method detection level. This ensures that the rates for both false positive and negative detections in the results were both <1%.

Basic data preparation included an investigation of potential coding errors, incomplete samples, and samples potentially affected by contamination.
The final data used to calculate the Pesticide Toxicity Index (PTI) did not include results with the REMARK_CD of “V” or the combination of REMARK_CD of “E” and VAL_QUAL_CD_TX of “v”. These indicate that potential lab contamination may be an issue with the result. Only results of DQI codes of “S” = "provisional" and “R” = "reviewed and approved" were retained for subsequent data analysis.
Specific instances of samples not being used:
-RESULT_VA samples with "NULL" value.
-Known and potential composite samples (samples with different start and end dates).
-Duplicate samples.
-Potential quality-control (QC) samples that were incorrectly coded as regular water samples. (i.e. samples with time ending in 1,3, or 8 may be replicate, spike, or blank samples, respectively.
-Samples with lab errors.
-Samples rejected through local water science center QC reviews, marked as internal-only, and not reviewed.

Pesticide Toxicity Index (PTI) scores were calculated by dividing each pesticide concentration by its relative acute toxicity to cladocerans (based on standardized bioassays and found at Nowell and others [2014]) to derive a toxicity quotient called toxic units (TU). The PTI is the sum of the TUs for each sample.
