Re: Residentia l Well Sampling Program

Dear

Please find enclose d th e laborator y analysi s repor t from th e independen t laborator y tha t analyzed the w ater sample collected in October 2008 from your home. Als o enclosed is a review by the consultant that has been retained to review all data that is related to human health that might be associated with the Olin facilities located at 51 Eames Street .

As you can see from the report, the only analytical results outside of the regulatory standards or guidelines are those for dissolved sodium. Th e guideline for sodium was established so that people on a salt restricted diet would be aware of the sodium content of their water. Whil e concentrations of other parameters including N-Nitrosodimethylamine (NDMA) were detected, they were all below regulatory standards or guidelines.

Should there be any questions afte r you review this informeition, you can call the facilit y at (978)658-6121. Inform them tha t you would like for me to cal l you , an d I will retum your call.

Sincerely,

Pt Steve Morrow Principal Environmental Specialis t

Dear Mr. Morrow:

Per your request, MACTEC Engineering and Consulting has evaluated the chemical dat a for th e wate r sampl e collecte d i n Octobe r 200 8 from th e residenc e i n Wilmington unde r Olin' s residentia l wel l samplin g program . Thi s evaluatio n wa s performed t o confir m th e suitabilit y o f drinkin g wate r a t th e residentia l property . Chemical concentration s i n the wel l water were compare d t o Massachusetts an d federa l drinking water standards and guidelines.

Attached i s a table summarizin g wel l monitorin g dat a fo r th e residence . Th e table list s al l detecte d analyte s an d thei r associate d concentrations . Th e appropriat e standard and/or guideline for each parameter is provided for comparison .

The reporte d concentratio n fo r sodiu m (2 2 mg/liter ) i s above th e concentratio n o f 2 0 mg/liter recommended i n the Massachusetts Drinking Water Guidelines (ORSG) . Ther e is no federal drinkin g water standard for sodium. Th e ORSG guideline was published so that public wate r supplie s coul d notif y peopl e on sal t restiicted diet s that the water i s a source o f sodiizm . Resident s o n sal t restricte d diet s shoul d b e awar e o f th e sodiiun content of the water. Elevated sodium concentration s are common i n grotmdwater i n the Wilmington area due to road salting practices.

The wate r testin g result s show n her e indicat e tha t th e overal l wel l wate r qtialit y i s consistent wit h availabl e Massachusett s an d federa l diinkin g wate r standard s an d guidelines.

If you have an y questions abou t the evaluation o r i f you require additiona l information , please feel free to contact Michael Murphy at (781) 245-6606.

Report Number : 360-19248- 1

Ttiis case narrative i s in the form of an exception repor t wtier e onl y ttie anomalies related to this report, method specific performance and/o r QA/QC issues are discussed. If there are no issues to report, thi s narrativ e wil l includ e a statemen t tha t document s tha t ther e ar e n o relevan t dat a issues as stipulated in the MCP reporting requirements.

In order to facilitate repor t review, a separate MCP Analytical Metho d Repor t Certification For m is included for each method requested.

It should be noted that samples with elevated Reporting Limit s (RLs ) as a result of a dilution may not be able to satisfy "MCP program" reporting limits in some cases i f the "adjusted" RL is greater than th e applicabl e MC P standard s o r criterio n t o whic h th e concentratio n i s bein g compared . Such increase s i n th e RL s ar e a n unavoidabl e bu t acceptabl e consequenc e o f sampl e dilutio n that enables quantification of target analytes which exceed the calibration range .

Calculations are performed before rounding to avoid round-off errors in calculated results.

All holdin g times wer e me t an d prope r preservatio n note d for th e method s performe d o n thes e samples, unless otherwise detailed in the individual sections below.

The sample s wer e receive d o n 10/08/2008 ; th e sample s arrive d i n goo d condition , properl y preserved and on ice. Th e temperatures o f the coolers at receipt were 2.8, 1.4 an d 0.8''C.

Note: Al l sample s whic h requir e therma l preservatio n ar e considere d acceptabl e i f th e arriva l temperature is within 2C of the required temperature o r method specified range. For samples wit h a specifie d temperatur e o f 4C , sample s wit h a temperatur e rangin g fro m jus t abov e freezin g temperature o f wate r t o 6 C shal l b e acceptable .

Case Narrative

TestAmerica West Sacramento Projec t Number G8J100200

WATER, 1625M , NDMA Sample(s): 1 , 2, 3, 4, 5, 6 As discussed, the associated laboratory contro l sample had a low recovery (70%) . The samples were re-extracted outside recommended holdin g times fo r confirmation. Bot h sets of results for these samples hav e been reported.

Sample(s): 1 , 2, 3, 4, 5, 6 The laboratory contro l samples (associated with the re-extraction) ha d low interna l standard recoveries (23% & 20%). Generally , data quality i s not considered affecte d if the intemal standard signal-to-noise rati o is greater than 10:1 , which is achieved for al l internal standards i n the laboratory contro l samples. Ther e should be no impact on the data.

There were no other anomalies associated with this project .
