Olin Perchlorate Site
| Olin Corporation and Standard Fusee Site |
 |
| Morgan Hill, CA |
The former Olin Corporation (Olin) site is a 13-acre parcel located in southern Morgan Hill. Olin manufactured signal flares at the facility for about 32 years from 1956 to 1988. Standard Fusee leased the site and manufactured signal flares for seven years from 1988 to 1995. Potassium perchlorate was used in the manufacturing of flares by both Olin and Standard Fusee from 1956 to 1996. Perchlorate contamination at the site occurred primarily from an unlined evaporation pond that received wastes from the cleaning of the ignition material mixing bowls, on-site incineration of cardboard flare coatings with residues on them, and accidental spills. The perchlorate leached through the soil into the groundwater over the 40 years of operation and created a ten-mile long plume of perchlorate. Below are links that give an up-to-date account of the Central Coast Water Board's efforts to oversee the cleanup of perchlorate in the groundwater below Morgan Hill, San Martin, and Gilroy.
