The following are my general comments:

1. Aeration device on sink was not removed- it would have been better for the sampler to select an alternative sampling site.  The high dissolved oxygen value suggests re-aeration was occurring.

2. It would have been better for the laboratory to conduct an analysis for total dissolved solids rather than estimating a value based on the conductivity reading.   The value is only a good estimate.

3. It is very good that the sampler noted the lack of odor and color.

4. Because of the estimated total dissolved solids, it would have been advisable to test the water for total hardness, iron, and manganese.   This is further supported by the fact that the water had a turbidity of 1.1 ntu.  This suggests there could be some reduced iron and manganese in the water.

5. In the field log – the sampler does not provide the units for the field measurements, but they appear to correct for this in the report.  It would have been best to have this on the field data sheet.

6. It is very good that you had the water tested for arsenic.

7. Overall, the screening test was very good.  There does seem to be a few parameters lacking, but this could be corrected by conducting some additional testing or making sure to allow a natural gas company to sample your water.

The primary issues with natural gas development have been associated with methane gas migration (Your OK), discolored water (your are lacking testing for iron and manganese),  and the potential for saltwater migration (Your OK).  In addition, it has been suggested that bromide may be a good secondary indicator for saline water and drilling mud migration.

I would like to take this opportunity to thank your fellow private well owner for releasing this data to help other well owners in the area.  Thanks for supporting the Citizens Groundwater Database a free program in Pennsylvania.
