A NACA-sponsored regulatory conference in April 1984 focused on During the summer of 1984, Holden visited representatives of four agr icultural chemical companies: Monsanto, FMC, Ciba-Geigy, and Union Carbide. Be also interviewed staff members of the National Agricultural Chemicals Association (NACA)

NACA appears to be responding to this challenge; the groundwater protection committee is actively involved in the development of a sampling protocol that could be used to monitor groundwater and soils for pesticide residues. NACA believes this protocol is a critical step in ensuring that future sampling yields reliable and useful water quality data.

at maximum concentrations of approximately 100 ppb. m e sampling undertaken by Monsanto to quantify groundwater problems associated with the production and application of alachlor has been limited largely to monitoring at manufacturing plants and to supporting work at the Water Quality Laboratory, Heidelberg College, Tiffin, Ohio.

FMC has taken partial responsibility for the degradation of groundwater quality on Long Island, and, where contamination has occurred from the use of carbofuran, FMC has joined with union Carbide in installing and recharging granular activated carbon systems for domestic water supply wells. In response to the groundwater contamination on Long Island, FMC established a research area near Salisbury, Maryland, where conditions were considered worst case (that is, homogenous sandy soils, low organic matter content, shallow water table, and so on)

; and metolachlor has been detected only in Wisconsin's groundwater at a maximum concentration of S5 ppb at a point source. Virtually all the groundwater detections of these herbicides have been at concentrations below health standards established in the various states.

The Ciba-Geigy representatives believed the lead time provided by PALs could prevent the occurrence of unnecessarily harsh regulatory responses. Union Carbide The purpose of Boldents visit to Union Carbide Agricultural Products was to discuss the company's perspective on the problems caused by the leaching of its product aldicarb (Temik)

From page 111... ...
The label restrictions established in Wisconsin after the detection of aldicarb in the groundwater of the Central Sands region were cited as a sensible and reasonable reaction to a problem that can most likely be managed by moderate changes in agricultural practices. In this regard, Union Carbide said pesticide manufacturers should be directly consulted by the EPA or state regulatory agencies if pesticide residues are detected in groundwater.
