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.
