1. Executive Summary:

1.1. Assessed Chemicals and Commodities:

This drinking water assessment was conducted for a petition submitted by the Interregional 

Research Project Number 4 (IR-4) to establish s-metolachlor tolerances for sesame, melon 

subgroup 9A, bushberry subgroup 13-07B, lowbush blueberry, caneberry subgroup 13-07A, 

sweet sorghum, leafy brassica greens subgroup 5B, turnip greens, carrot, cucumber, okra, bulb 

onion subgroup 3-07A and green onion subgroup 3-07B. S-Metolachlor is a broad spectrum 

herbicide that acts to inhibit seedling development. It can be applied to crops as a pre-emergent 

or post-emergent broadcast ground application as well as a surface band application. This 

assessment was based on information contained in the Dual Magnum



(EPA Reg. No. 100-816) 

label.

This drinking water assessment was conducted on the parent s-metolachlor and its major 

degradates ethanesulfonic acid (ESA) and oxanilic acid (OA). It is important to note that the 

environmental fate data has been bridged from the racemic mixture (50:50) of metolachlor to the 

newer isomer (88:12) s-metolachlor, based on similarities in environmental fate behavior. 

1.2. Application Rates:

The Estimated Drinking Water Concentrations (EDWCs) for use in the human dietary health risk 

assessment are based on the maximum new proposed application rate specified in the Dual 

Magnumlabel, which is a single yearly application of 3.81 lbs a.i./acre for use on caneberry. 

The application rate for the degradate ESA was calculated by multiplying the application rate of 

the parent active ingredient by the fraction of the maximum detected degradate from the 

submitted fate studies (0.12; MRID 43928936) and then multiplying by the ratio of the molecular 

weights of the degradate to parent (329.1 g/mol /283.8 g/mol). Following this equation, the 

maximum single application rate for the ESA degradate is 0.53 lbs a.i./acre for caneberry use. 

The application rate for the OA degradate was calculated by multiplying the application rate of 

the parent active ingredient by the fraction of the maximum detected degradate from the 

submitted fate studies (0.28; MRID 41309801) and then multiplying by the ratio of the molecular 

weights of the degradate to parent (279.1 g/mol /283.8 g/mol). Following this equation, the 

maximum single application rate for the OA degradate is 1.05 lbs a.i./acre for caneberry use. 

S-Metolachlor and its degradates ESA and OA have been detected extensively in surface water 

and groundwater as reported in the Tolerance Reassessment Document (US EPA, 2002). Based 

on the proposed application rates and the environmental fate properties of s-metolachlor, surface

water and groundwater contamination may occur from s-metolachlor as well as its degradates 

ESA and OA.

1.3. Modeling Approach:

Tier I and Tier II screening models were employed for this assessment. For surface water, 

PRZM/EXAMS (PE5) and FIRST (FQPA Index Reservoir Screening Tool) Version1.1.1 models

were used to estimate drinking water concentrations for the parent s-metolachlor and the ESA 

and OA degradates, respectively. The SCI-GROW model (Screening Concentration in Ground 

Water Program Version 2.3) was used to predict the maximum acute and chronic concentrations 

present in shallow groundwater. 

1.4. Monitoring Data:

Since the previous EDWCs for surface water for the parent s-metolachlor were based on 

NAWQA monitoring data, a search of the available monitoring data was performed on March 30, 

2010 to ensure that the most current monitoring data were considered in this assessment. The 
3

data set captured the timeframe of October 1991 to October 2009 and included the parent smetolachlor and its degradates ESA and OA. Based on a review of the current monitoring data, 

concentrations of parent s-metolachlor and its degradates were less than values reported from the 

previous monitoring data (US EPA, 2002). Therefore, EDWCs based on previous monitoring are 

still valid.

1.5. Results and EDWC Recommendations:

A summary of recommended surface and groundwater EDWCs for the human dietary risk 

assessment for the parent s-metolachlor and its degradates ESA and OA are presented in Table 1. 

 Table 1 contains EDWCs based on this current assessment as well as values reported in the 

previous drinking water assessment (D324967) dated 20 March 2006. Values derived from the 

current modeling exercise are bolded in Table 1.

2. Environmental Fate and Transport Summary:

The information from all acceptable and upgradable environmental fate data indicate that parent 

metolachlor/s-metolachlor appears to be moderately persistent to persistent. It is mobile to highly

mobile in different soils and has been detected extensively in surface water and groundwater. 

Metolachlor/s-metolachlor degradation appears to be dependent on microbially mediated (aerobic 

soil metabolism t1/2 = 66 days, 37.8 days, 37.8 days, 14.9 days, 13.9 days, and 50.3 days, anaerobic 

soil metabolism t1/2 =81 days) and abiotic processes (photodegradation in water t1/2 = 70 days under 

natural sunlight and photodegradation on soil t1/2 = 8 days under natural sunlight).

The major degradates were identified as CGA-51202 (metolachlor OA), CGA-50720, CGA-41638, 

CGA-37735, and CGA-13656. Subsequent studies identified CGA-354743 (metolachlor ESA) as a 

major degradate (of these major degradates, metolachlor ESA and metolachlor OA have been 

identified in both groundwater and surface water). Depending on the soil (i.e. organic matter 

content), metolachlor/s-metolachlor has the potential to range from a moderately mobile to a highly

mobile material with Kd values ranging from 0.11 to 44.8 mL g/oc, and Koc values ranging from 

21.6 to 367 L/kg oc. 

EFED concluded there is no difference in soil sorption affinity between metolachlor and smetolachlor. There was no statistical difference between Koc values in non-paired batch equilibrium 

studies; similar Koc coefficients for metolachlor (mean Koc=249.250) and s-metolachlor (mean 

Koc=265.875) were observed in paired batch equilibrium studies. These data suggest that 

metolachlor and s-metolachlor are expected to be highly mobile to mobile in soil and water 

environments. A more detailed summary of the fate data are presented in Appendix A.

Field dissipation studies indicate that metolachlor/s-metolachlor is persistent in surface soil with half 

lives ranging from 7 to 292 days in the upper six inch soil layer depending on geographic location. 

Metolachlor/s-metolachlor was reportedly detected as deep as the 36 to 48 inch soil layer in some of 

the studies. Metolachlor OA (CGA-51202), was detected (0.11 ppm) as deep as the 30-36 inch soil 

depth (MRID No. 41335701); CGA-40172 was detected as deep as the 36-48 inch depth (MRID No. 

41309802); CGA-40919 was detected in the 36-48 inch depth (0.21 ppm in MRID No. 41309802); 

and CGA-50720 was not detected (LOD = 0.07 ppm) in any soil segment at any interval.

3. Water Resources Summary:

3.1. Monitoring: 

S-Metolachlor and its degradates ESA and OA have been detected extensively in surface water 

and groundwater. A more detailed summary of the monitoring data can be found in the 

Tolerance Reassessment Document (US EPA, 2002). Since the previous EDWCs for surface 

water for the parent s-metolachlor were based on NAWQA monitoring data, a search of the 

available monitoring data was performed on March 30, 2010 to ensure that the most current 

monitoring data were considered in this assessment. The data set captured the timeframe of 
5

October 1991 to October 2009 and included the parent s-metolachlor and its degradates ESA and 

OA. Based on a review of the current monitoring data, concentrations of parent s-metolachlor 

and its degradates were less than values reported from the previous monitoring data (US EPA, 

2002). Therefore, EDWCs based on previous monitoring are still valid. However, some of the

previously reported EDWCs, which were based on monitoring data, were exceeded based on 

modeled concentrations derived from the proposed uses in this assessment.

3.2. Drinking Water Exposure Modeling:

EDWCs were generated using EFED’s standard suite of models. The proposed uses from the 

provided label were assessed. Two specialty scenarios, OR Berry OP and CA Cole Crop RLF 

were used to characterize caneberry and leafy Brassica and turnip greens, respectively. 

The Pesticide Root Zone Model (PRZM v3.12.2, May 12, 2005) and Exposure Analysis 

Modeling System (EXAMS v2.98.04.06, April 25, 2005) are simulation models coupled with the

input PE5.pl shell (PE5, PE Version 5.0, November 15, 2006) was used to generate EDWCs of 

the parent s-metolachlor that may occur in surface water used as drinking water. The PRZM 

model simulates pesticide movement and transformation on and across the agricultural field 

resulting from crop applications. The EXAMS model simulates pesticide loading via runoff, 

erosion, and spray drift assuming a standard watershed of 172.8 ha that drains into an adjacent 

standard drinking water index reservoir of 5.26 ha, an average depth of 2.74 m. A more detailed 

description of the index reservoir watershed can be found in Jones et al., 1998. The coupled 

PRZM/EXAMS model and users manuals may be downloaded from the U.S. Environmental 

Protection Agency (EPA) Water Models web-page (USEPA, 2006). Percent Crop Areas (PCA) 

that account for the maximum area within a watershed that may be planted with the modeled 

crop are applied to concentrations predicted by PRZM/EXAMS.

In addition, the standard FL carrot scenario is based on a sandy soil, although carrots in FL are 

oftentimes grown in muck soils. In order to characterize the potential impact on EDWCs based 

on FL carrots grown in muck soils, the organic carbon and bulk density parameters from the first 

soil horizon were modified from the standard carrot scenario. The percent organic carbon 

content of 1.16% was changed to 12.00% (Brady, 1990) and the bulk density was changed from 

1.65 g/m3to 1.50 g/m3to reflect muck characteristics of the soil. The acute, chronic and cancer 

chronic EDWCs were 52.57 μg/L, 7.75 μg/L, and 4.99 μg/L, respectively. In general, EDWCs 

values generated using the muck soil scenario are lower than those derived based on the standard 

sandy soil FL carrot scenario. These values are used to characterize EDWCs associated with 

carrots grown in muck soils and are further discussed as uncertainty in this assessment.

The FIRST (FQPA Index Reservoir Screening Tool) model is a Tier I model used to estimate 

both acute and chronic pesticide concentrations in untreated drinking water. The FIRST model 

was employed to derive EDWCs for the ESA and OA degradates only. 

The SCI-GROW model (v2.3, Jul. 29, 2003) is a regression-based screening tool used to estimate 
6

pesticide concentrations found in ground water used as drinking water. SCI-GROW was 

developed by fitting a linear model to ground water concentrations with the Relative Index of 

Leaching Potential (RILP) as the independent variable. Groundwater concentrations were taken 

from 90-day average high concentrations from Prospective Ground Water studies. The RILP is a 

function of aerobic soil metabolism and the soil-water partition coefficient. The output of SCIGROW represents the concentrations of residues that might be expected in shallow unconfined 

aquifers under sandy soils, which are representative of the ground water most vulnerable to 

pesticide contamination and likely to serve as a drinking water source. The SCI-GROW model 

and User’s Manual may also be downloaded from the EPA Water Models web-page 

http://epa.gov/oppefed1/models/water/ (USEPA, 2006). 

3.3. Surface Water Model Inputs:

Due to the stability and mobility of the parent s-metolachlor, the compound may move from the 

treated field to surface water through run-off which occurs shortly after application (i.e. rainfall 

events). Because limited data are available on the fate characteristics of the degradates ESA and 

OA, the aerobic soil metabolism rate constant was conservatively estimated using the 

Comparative Aerobic Soil Metabolism Study (MRID 43928936) submitted to support bridging 

of fate data from the racemic to the s-isomer of metolachlor. Aerobic soil metabolism half-lives 

were estimated using only the decline portion of the data for each degradate. Half-lives for other 

parameters (i.e. aerobic aquatic metabolism, hydrolysis, photolysis) where no data were available 

were conservatively assumed to be stable as per EFED guidance. An adsorption/desorption study

(MRID 40494605) was previously submitted for metolachlor OA. The lowest non-sand Kd 

value (0.079 mL g/oc for Maryland clay) was selected for surface water degradate modeling, and 

the lowest Koc measured for all available soil types (2.82 L/kg oc for the Maryland clay) was 

used for groundwater modeling. An adsorption/desorption study (MRID 44931722) was 

previously submitted for metolachlor ESA and is currently under review. The lowest non-sand 

Kd value (0.041 mL g/oc for Maryland clay) was selected for surface water degradate modeling,

and the lowest Koc (2.01 L/kg oc for the Maryland sandy loam) was used for groundwater 

modeling.

The drinking water concentrations derived from surface water for the parent s-metolachlor and its 

degradates (ESA and OA) were estimated using PRZM/EXAMS and FIRST models, 

respectivley. Input paremeters for s-metalachlor, ESA, and OA are reported in Tables 2, 3, and 

4, respectively. Model outputs are included in Appendix B.

3.4. Groundwater Modeling Inputs:

Due to the stability and mobility of the parent s-metolachlor, the compound may move from the 

treated field to groundwater through leaching. 

The drinking water concentrations derived from groundwater for the parent s-metolachlor and its 

degradates ESA and OA were estimated using the SCI-GROW model. Input paremeters for smetalachlor, ESA, and OA are reported in Tables 5, 6, and 7, respectively. Model outputs are 

included in Appendix B.

3.5. Modeling Results:

For this assessment, the surface and groundwater EDWCs for the parent s-metolachlor and its 

degradates ESA and OA are presented in Tables 8, 9, and 10, respectively. For drinking water 

derived from surface water for the parent s-metolachlor, the maximum reported acute 

concentration of 71.33 μg/L for the Florida carrot (mineral soil) scenario does not exceed the 

previous EDWC of 77.6 μg/L from the monitoring data reported in the previous drinking water 

assessment (D324967) dated 20 March 2006. However, the maximum annual mean (chronic) 

concentration of 18.15 μg/L from the California Cole Crop scenario and the maximum 30 year 

annual average concentration of 9.15 μg/L from the Kansas Sorghum scenario exceed the 

previous reported EDWC of 4.3 μg/L from the monitoring data reported in the previous drinking 

water assessment. For the degradate ESA, the FIRST model’s acute and chronic (annual 

average) concentrations of 47.61 μg/L and 34.04 μg/L, respectively, exceed the previously

reported EDWCs of 31.9 μg/L and 22.8 μg/L from the modeling data reported in the previous 

drinking water assessment. For the degradate OA, the FIRST model’s acute and chronic (annual 

average) concentrations of 93.57 μg/L and 66.62 μg/L, respectively, exceed the previously

reported EDWCs of 91.4 μg/L and 65.1 μg/L from the modeling data reported in the previous 

drinking water assessment. 

For drinking water derived from groundwater for the parent s-metolachlor, the SCI-GROW

model’s acute and chronic concentration of 5.26 μg/L does not exceed the previously reported 

EDWC of 32.8μg/L from the monitoring data reported in the previous drinking water 

assessment. For the degradate ESA, the SCI-GROW model’s acute and chronic concentration of 
14

45.9 μg/L does not exceed the previously reported EDWC of 63.7μg/L from the monitoring data 

reported in the previous drinking water assessment. However, for the degradate OA, the SCIGROW model’s acute and chronic concentration of 29.7 μg/L does exceed the previously

reported EDWC of 13.4μg/L from the monitoring data reported in the previous drinking water 

assessment.

4. Uncertainties:

In order to characterize EDWCs for carrots grown in muck soils, the organic carbon and bulk 

density parameters from the first soil horizon were modified from the standard carrot scenario. 

Based on these modifications, the predicted acute, chronic, and cancer chronic EDWCs for FL

carrots grown in muck soils are 52.57 μg/L, 7.75 μg/L, and 4.99 μg/L, respectively. Predicted 

EDWCs for FL carrots grown in muck soils are generally lower that EDWCs based on the 

standard sandy soil scenario. EDWCs are presented for comparative purposes only and are not 

included in Table 8 of the risk assessment. Therefore, it is possible that FL carrot EDWCs 

presented in Table 8 may overestimate exposure for carrots grown in muck scenarios.

Appendix A: Environmental Fate Assessment (from the 1994 RED)

Metolachlor appears to be stable to hydrolysis at pH’s of 5, 7, and 9 without significant 

degradation of parent material after 30 days.

The aqueous photolysis half-life was 70 days when exposed to natural sunlight and 0.17 day

when exposed to artificial sunlight (450 watt mercury arc lamp with light intensity of 4500-4800 

uW/cm2). After 30 days exposure to natural sunlight the degradation products were CGA-41638 

(3.63% of applied radiocarbon), CGA-51202 (3.54%), CGA-46129 (3.42%), CGA-50720 

(3.20%), and parent metolachlor remaining was 62.92%.

The soil photolysis half-life of metolachlor when exposed to natural sunlight was 8 days, and 

when exposed to artificial light conditions (mercury arc lamp with intensity of 1600-2400 

uW/cm2) the half-life was 37 days. The major degradates reported after 21 days exposure to 

natural sunlight were CGA-51202 (maximum of 3.4% of applied radiocarbon), CGA-37735 

(9.0%), CGA-41638 (5.7%), and CGA-37913 (7.3%).

Under aerobic soil conditions metolachlor degraded with a half-life of 67 days in a sandy loam 

soil. The major metabolite was CGA-51202 (maximum of 28.09% of applied radioactivity at 90 

days posttreatment). Other identified metabolites were CGA-37735 (maximum of 14.85% at 272 

days), CGA-41638 (maximum of 2.06% at 90 days), and CGA-13656 (maximum of 1.02% 

immediately posttreatment). Other metabolites were detected but not quantified were CGA40172, CGA-41507, CGA-40919, and CGA-37913.

The aerobic aquatic metabolism half-life of metolachlor was 47 days. The major metabolites in 

the sediment were CGA-41507 (3.34% of applied radiocarbon at 29 days), CGA-50720 (1.17%), 

CGA-40172 (1.13%), CGA-46127 (1.54%), and parent metolachlor was 34.56%. In the water 

fraction after 29 days incubation parent metolachlor was 30.90% and the metabolite CGA-41507 

was 1.21% and CGA-51202 was 1.9(%.

Under anaerobic soil conditions metolachlor degraded with a half-life of 81 days in a sandy loam 

soil that was incubated under anaerobic conditions for 60 days at 25oC following 30 days of 

aerobic incubation. The major degradate in both the soil and flood water was CGA-51202 

(maximum of 23.33% of applied radiocarbon at 29 days after anaerobic conditions were 

established); and other reported degradates were CGA-37735 (1.25% at 29 days), CGA-41638 

(8.3% at 60 days), CGA-13656 (1.46% at 29 days), and CGA-50720 (maximum of 7.34% at 60 

days).

The anaerobic aquatic metabolism half-life for metolachlor was 78 days. In the anaerobic waters 

the major degradates were CGA-40172 (maximum of 5.64% at 12 months), CGA-37913 

(maximum of 4.28% at 6 months), CGA-46127 (maximum of 4.69% at 12 months) and CGA41507 (maximum of 4.85% at 6 months). The major degradates in sediment were CGA-41507 

(maximum of 15.88% of applied radiocarbon at 12 months), CGA-40172 (maximum of 3.18% at 
19

12 months), CGA-46127 (maximum of 13.02% at 12 months), CGA-50720 (maximum of 1.67% 

at 29 days), and CGA-37913 (maximum of 2.33% at 6 months), and after 12 months the 

sediment contained 1.47% parent metolachlor.

In the unaged portion of the leaching and adsorption and desorption study metolachlor was 

shown to range from being highly mobile in a sand soil (kd value of 0.08) to being moderately

mobile (Kd value of 4.81 in a sandy loam) from column leaching studies using four soils. The 

leachate contained from 15.03% to 82.91% (comprised of 75.5% parent metolachlor, 1.14% of 

CGA-51202, 3.69% of CGA-37735, and 2.26% CGA-41638) of the applied radioactivity. In 

batch equilibrium studies employing the same four soils, the Freundlich adsorption (Kad) values 

ranged from 0.108 to 2.157. These data indicate that metolachlor has the potential to range from 

being moderately mobile material (clay soil and sandy loam soil) to being a highly mobile 

material (loam soil and sand soil).

In the aged leaching portion of the leaching and adsorption and desorption study the reported 

cumulated Kd for aged metolachlor and its degradates in columns of an Iowa sandy loam soil 

was 2.01. This indicates that metolachlor and its identified degradates (CGA-51202, CGA37735, and CGA-41638) have the potential to be mobile since in other studies it was shown that 

metolachlor and its CGA-51202 degradate leached the slowest in the Iowa sandy loam soil 

compared to their leaching rate in the other three soils tested. Batch equilibrium studies showed 

that CGA-51202 has the potential to be extremely mobile with reported Freundlich adsorption 

(Kad) values ranging from 0.04 in the Maryland sand to 0.171 in the Iowa sandy loam soil.

Laboratory volatility studies indicated that volatility is not a significant mode of dissipation for 

metolachlor from soil. The maximum dissipation was 0.05% of the metolachlor dose volatilizing 

per day.

In numerous terrestrial field dissipation studies using metolachlor (Dual 8E and Dual 25G) both 

applied at 4 and 6 lb ai/A the half life of metolachlor in the 6-12 inch soil layer ranged from 7 

days (Iowa) to 292 days (California) with a range of the total water applied ranging from 16.97 

inches to > 40 inches during the study period. Detections of metolachlor were made as far as the 

36-48 inch soil layer in some of the tests. The degradate CGA-40172 (0.07 ppm) and CGA40919 (0.21 ppm) were detected in the 36-48 inch soil layers in one Iowa site. CGA-50720 was 

not detected (0.07 ppm) in any soil sampled at any interval.

Metolachlor appears to have a low potential to bioaccumulate in fish with a reported whole body

bioconcentration factor of 69X and a whole body elimination of 93% after 14 days depuration.
