Kasson Rd,,Tracy, CA <br /> PA-1100066 <br /> :Dear Mr. Quaresma: <br /> We have received the analytical results(attached) for the water sample collected on your property as part <br /> of the above Soil Suitability Study. Details of the sample collection were included on page 4 of the report. <br /> Dibromochloropropane (DBCP)was not detected in the sample. <br /> Nitrate was detected at a concentrationf:70.4Ag -NO3. This salt exceeds the aximum <br /> Contaminant Level (MCL) of 45 mg/L-N by the US EPA. In o , his high level is not <br /> unusual for the area. You may wish to discuss methods of reducing the nitrate levels in your drinking <br /> water with the Environmental Health Department and/or a well contractor. For health reasons, we <br /> .recommend that the well water not be consumed until nitrate levels can be reduced to below the MCL. <br /> Utilizing bottled water for drinking water may be a good alternative to consider. <br /> Although nitrate is a naturally-occurring compound necessary for plant growth, it can cause health <br /> problems when present at high levels in drinking water. The most common health effect of nitrates in <br /> water is methemoglobinemia or blue baby syndrome, which results in reduced oxygen supply to vital <br /> tissues. Pregnant women and certain others can also develop methemoglobinemia. Symptoms include a <br /> bluish color of the skin, as well as headache, dizziness,weakness,and difficulty breathing. Ingestion of <br /> I� <br /> high levels of nitrates ales over time can also lead to gastric problems. <br /> We appreciate the opportunity to work on this project. If we can be of any further assistance, please do <br /> not hesitate to call. <br /> Sincerely, <br /> Live Oak GeoEnvlroamental, Inc. <br /> Delo <br /> David J.
