Organophosphate insecticides, including chlor- pyrifos, diazinon, and methidathion, are applied to dormant orchards in the San Joaquin Valley, California, during late December through January.

This time frame coincides with the period of heaviest rainfall in the valley, and rainfall mobilizes a portion of these pesticides from the orchards. The pesticides enter the San Joaquin River and have. NONPOINT SOURCES OF PESTICIDES IN THE SAN JOAQUIN RIVER, CALIFORNIA: INPUT FROM WINTER STORMS, By Joseph L Domogolski Abstract Organophosphate insecticides, including chlorpyrifos, diazinon, and methidathion, are applied to dormant orchards in the San Joaquin Valley, California, during late December through by: 8.

The higher pesticide loads in the Sacramento River compared with those in the San Joaquin River can be attributed to the greater amount of rainfall in the Sacramento Valley.

The use patterns and water solubility of the pesticides can account for the observed temporal and spatial distributions in. The guidance is organized around the six NPS categories identified in the Plan for California’s Nonpoint Source Pollution Control Program of agriculture, forestry, urban areas, marinas and recreational boating, hydromodification, and wetlands/riparian areas/vegetated treatment systems.

The term "nonpoint source" is defined to mean any source of water pollution that does not meet the legal definition of "point source" in section (14) of the Clean Water Act. The Clean Water Act (CWA) defines a point.

In San Joaquin River samples, 26 pesticides and (or) degradates were detected, and the average number detected per sample was 9. Dissolved pesticide concentrations entering the Sacramento–San Joaquin Delta from the Sacramento and San Joaquin Rivers, California, – U.S.

The total number of pesticide detections varied little between river systems and between sites, but the maximum concentrations of most pesticides occurred in San Joaquin River samples.

divided into three sections: Sacramento River Basin, San Joaquin River Basin, and Tulare Basin. A common element in all three watersheds is that monitoring programs are designed primarily to address potential nonpoint source impacts, since the most significant water quality problems in the Region result from nonpoint sources (see Regional assessment of nonpoint-source pesticide residues in ground water, San Joaquin Valley, California (SuDoc I /) [Domagalski, Joseph L.] on *FREE* shipping on qualifying offers.
