City, State, Zip Code: 4&kApD, rt . 952z� RE: DBCP in your Water Well Site Approval Pa-0000000 At 2_13ef/ /0. .11-,gA1A.' 12;j> (site address) As part of the Site Approval water test results (per our condition B) were submitted by in which a sample taken /,Y.Y , � , 200f, was tested for the chemical Dibromochloropropane (DBCP) and showed results of I. ,o ug/L (parts per billion) in your domestic well well at at the above referenced address. The State Department of Health Services adopted a standard of 0.2 parts per billion (ppb) for DBCP in public drinking water systems in 1989, however, private well owners are not legally required to meet this standard. As a precaution for yourself and family, we would suggest that you have your domestic well tested annually to verify if the above-described chemical rises above state drinking standards. If your private and/or agricultural well analysis for Dibromochloropropane exceeded the State standard of 0.2 ppb, the following alternatives are being provided for your guidance: 1. As a temporary measure, it is recommended that bottled drinkiniz water be used if this well is supplying drinking water. 2. In cases where exposure may continue indefinitely, such as with contaminated private wells, installation of a water treatment device, such as a filter, may be advisable. However, using bottled water or installing a water treatment device at the kitchen water tap, will not stop exposure to DBCP if it is in your private water supply. Most treatment units sold for home installation only treat water at the point of use, such as the kitchen faucet, and do not prevent exposure through skin contact, bathing or inhalation. As a result, point of entry filters, which treat water for the entire house, are recommended because they remove all potential sources of exposure. The "granular activated carbon" filter is the recommended water treatment device in this case. It operates by passing the well water through a charcoal bed, thereby absorbing the DBCP contaminant.
