**SUBJECT:** Drinking water assessment for mandipropamid and its two

vegetables, cucurbits, fruiting vegetables, grapes, leafy vegetables,
potatoes, tomatoes, tuberous and corm vegetables.

**[INTRODUCTION]{.underline}**

This memorandum transmits the Tier I Estimated Environmental
Concentrations (EECs) resulting from 4 applications of 0.13 lb ai/acre
of mandipropamid and its two degradates (SYN500003 and SYN504851). HED
requested to include these two degradates in this water assessment due
to their high amounts formed in laboratory studies (9.4 and 38% of the
applied radioactivity under aerobic aquatic conditions), and
toxicological concerns.

**[CONCLUSIONS]{.underline}**

A screening assessment of estimated environmental concentrations (EECs)
for mandipropamid and its major aquatic degradates (SYN500003 and
SYN504851) in drinking water was conducted. Screening models were used
to determine estimated concentrations in ground water and surface water.
A national PCA of 0.87 (default) was used in order to better reflect the
expected exposures from the proposed uses.

Based on surface (FIRST 1.1.0) and ground water (SCI-GROW 2.3) modeling
, the surface and groundwater Expected Environmental Concentrations
(EEC) of mandipropamid and its major degradates (SYN500003 and
SYN504851) are shown in table 1.

**[BACKGROUND]{.underline}**

Mandipropamid is a new pesticide (also known as Revus) is the active
ingredient in the fungicide

Revus^TM^, which is proposed for control of a certain diseases in
brassica vegetables, bulb vegetables,

cucurbits, fruiting vegetables, grapes, leafy vegetables, potatoes,
tomatoes, tuberous and corm

vegetables.

Groundwater and surface water monitoring data are not available to the
Environmental Fate and Effects Division (EFED) for mandipropamid or its
degradates (new chemical). Screening models were used to determine
drinking water EECs.

**[GROUND WATER]{.underline}**

The SCI-GROW model is based on scaled ground water concentration from
ground water monitoring studies, environmental fate properties (aerobic
soil half-lives and organic carbon partitioning coefficients-K~oc~ \'s)
and application rates. The model is based on permeable soils that are
vulnerable to leaching and on shallow ground water (10-30 feet).
SCI-GROW version 2.3 (executable file dated 08/05/2003) was used to
estimate concentrations of mandipropamid and its major degradate
(SYN500003, SYN504851) that could be found in drinking water derived
from ground water, using the input values listed in the table 3.

\*: Application rate was calculated by multiplying the parent appl.
rates X maximum percent of degradate formed X (degradate M.Wt/parent
M.Wt).

Results from the SCI-GROW screening model predict that the maximum
chronic and acute concentration of parent mandipropamid and its major
degradate (SYN500003, SYN504851) in shallow ground water is not expected
to exceed 4.19E+01 µg/L for the current maximum seasonal use rate.
