stratified, random statistical survey 

design. Sampling within these 

watersheds began in 2004 and is 

ongoing in selected watersheds. There 

are an additional 25 sites where 

monitoring began in 2010 to refine the 

approach for identifying vulnerable 

watersheds. EPA is evaluating the 

results of the atrazine monitoring 

program, also in part, to identify the 

characteristics of those watersheds that 

resulted in atrazine exposures exceeding 

the Agency’s LOC and to extrapolate 

those results to other non-monitored 

locations to determine where atrazine 

concentrations may exceed the LOC. 

In December 2007, EPA presented to 

the SAP the use of the Comprehensive 

Aquatic Systems Model (CASM) as a 

tool to determine an LOC that relates 

time variable monitoring data to effects 

identified in a series of microcosm and 

mesocosm studies. The SAP 

recommended that EPA: 

1. Work with the CASM–Atrazine 

model to make the population time 

series more realistic; 

2. Provide a better validation of this 

model, and 

3. Conduct a more comprehensive 

sensitivity analysis. 

In May 2009, EPA presented a simpler 

alternative to the CASM-based approach 

to relate surface water monitoring data 

to the microcosm and mesocosm data, 

called the PATI. Other issues presented 

at this meeting included a revised 

assessment of the microcosm and 

mesocosm exposure profiles, an update 

on the ecological monitoring program 

results, interpretation of the monitoring 

results with PATI, identification of the 

watershed factors driving atrazine 

runoff, and extrapolation of those 

results to the entire atrazine use area to 

identify other areas where atrazine 

exposures may exceed the LOC. The 

2009 Panel suggested that both the 

CASM–Atrazine model (presented by 

Syngenta) and PATI were suitable 

assessment tools for atrazine. The PATI 

model was recommended by the SAP as 

a generic assessment tool for developing 

an LOC, while CASM was 

recommended by the SAP as a sitespecific assessment tool because of the 

need for extensive site-specific data. 

The Panel noted that a limitation in the 

CASM model is the lack of 

understanding of the sensitivity of 

model predictions with correlations 

among model parameters. The SAP 

recommended that EPA re-evaluate the 

meso/microcosm data set for study 

quality and concentration-specific 

effects, and provided additional 

citations for meso/microcosm studies to 

consider including in the assessment. 

They also recommended using a 

probabilistic approach to determine the 

LOC. The SAP concurred with EPA’s 

incorporation of depth to impervious 

layer and slope to identify vulnerable 

watersheds for atrazine runoff as part of 

the atrazine vulnerability index. They 

also cautioned EPA that several 

watershed factors such as atrazine use 

intensity and rainfall are temporally 

dependent and, therefore, should not be 

considered minimum criteria in the 

vulnerability index.
