Hello,
I have reviewed the final Drinking Water Source Protection (DWSP) plan for the Hyde Park City Hall Well; however,
before the Division can concur, the following items must be addressed:
Section 2.0 - Delineation Report
A statement is made that the pumping tests are included in Appendix C. Are raw data available? If so, please provide a
copy of the raw data from the constant-rate pumping test. I would like to check the value for transmissivity derived
from specific capacity information with one calculated using the Cooper Jacob method, which is typically more accurate.
The equation is as follows: T = 2.303Q / 4π∆s where T is transmissivity in ft2/day, Q is the constant discharge rate in
ft3/day, and ∆s is the change in drawdown given by the straight line over one log-cycle. The use of specific capacity will
result in an over approximation of the transmissivity, which will result in longer/skinnier zones when modeled.
Something needs to be done about the upgradient extents of zone 4, and possibly zone 3 (if it crosses the fault
boundary). I apologize I didn't catch this in the PER phase, but zones 3 and 4 extend well beyond the alluvial aquifer and
cross the fault zone in the up-gradient direction. Once the zones cross the fault zone, the formation is bedrock and the
groundwater flow direction, hydraulic gradient, and aquifer parameters are likely much different than those determined for
the alluvial aquifer. As such, you must take this change in aquifer type into consideration when delineating the zones. For
the other two Hyde Park Wells, the up-gradient boundary for zones 3 and 4 were delineated using hydrogeologic mapping
and it was assumed that the two zones shared the same upgradient boundary. This is a very common approach to
modeling zones for wells that are near the base of a mountain front. I have attached the final DWSP plans for the other
two Hyde Park Wells for your review. I would expect the delineation for the City Hall Well to also follow this logic. Please
update the delineation reflecting the change in aquifer conditions that occurs at the mountain front/fault
boundary.
If the modified delineation for the City Hall Well results in changes to the potential contamination source inventory, be sure
to update subsequent sections of the plan to address any changes.
Also, before the Division can concur, the Division will need proof that a map of the final zones has been provided to
Hyde Park City to be covered under their ordinance. Even though the well is Hyde Park City's source, we do need
documentation that the city has received the final zones and will be enforcing their ordinance in those areas.
As an aside, I understand from Melissa that there may be some questions about the maximum pumping rate used in the
delineation and how it relates to the equipped pumping rate. Source protection staff do not make determinations on safe
yield nor do we have any say in what a well is equipped at. That decision is typically handled through the well equipping
plan approval process. If you have more questions about the well's equipping pumping rate, please reach out to Hunter
Payne (cc'd on this email).

Afternoon Deidre,

Thanks for your review and comments, they’re very reasonable and helpful. I appreciate this chance to gain
hydrogeologic knowledge from you. Just need a couple of clarifications before we move forward on this
report revisions:
Transmissivity Verification
I spent some time on playing around the Cooper-Jacob Straight Line Method, the fitted slope is
about 7.9065, and the calculated transmissivity is 7853 ft2/day per this method. Meanwhile, the
transmissivity calculated from Specific Capacity Method is approximately 6122 ft2/day. Attached
1/27/25, 7:59 AM State of Utah Mail - Submission of Hyde Park Drinking Water Source Protection Plan - Hyde Park City Hall Well
https://mail.google.com/mail/u/0/?ik=c26a5d4cc7&view=pt&search=all&permthid=thread-f:1811117967808446822&dsqt=1&simpl=msg-f:181111796…12/51
includes the constant-rate pumping data with my calculations and the step test graph for your
refences. Please let me know if the calculated transmissivity works for you. Once the transmissivity
parameter was finalized and concurred by DEQ, we will move on the report revision.

Upgradient Boundaries Revision
Thank you for pointing this out. The long and narrow boundaries are indeed something we can refine. I
believe the hydrogeologic mapping will provide a more accurate representation for Zone 3 and Zone 4. We
will update the zones accordingly in the revised DWSP plan.

City Awareness & Enforcement
An official letter from HP City confirming their receipt of the final zoning map and commitment to
enforcing their source protection ordinance within the identified zones will be included in the revised
DWSP plan.

Regards,
Haiming

Thanks. I reviewed the data provided and calculated a transmissivity of 8,105 ft2/day. It is very close to what you
calculated. I think the only difference may be in how we calculated the delta s over one log cycle. I took the difference
between the drawdown at 100 minutes and the drawdown at 1,000 minutes (change of s over one semi-log cycle). My
value for delta s was a bit different from yours, but I'm okay with what you have calculated for T.

Hello,
I have reviewed the final Drinking Water Source Protection (DWSP) plan for the Hyde Park City Hall Well; however,
before the Division can concur, the following items must be addressed:
Section 2.0 - Delineation Report
A statement is made that the pumping tests are included in Appendix C. Are raw data available? If so, please provide a
copy of the raw data from the constant-rate pumping test. I would like to check the value for transmissivity derived
from specific capacity information with one calculated using the Cooper Jacob method, which is typically more accurate.
The equation is as follows: T = 2.303Q / 4π∆s where T is transmissivity in ft2/day, Q is the constant discharge rate in
ft3/day, and ∆s is the change in drawdown given by the straight line over one log-cycle. The use of specific capacity will
result in an over approximation of the transmissivity, which will result in longer/skinnier zones when modeled.
Something needs to be done about the upgradient extents of zone 4, and possibly zone 3 (if it crosses the fault
boundary). I apologize I didn't catch this in the PER phase, but zones 3 and 4 extend well beyond the alluvial aquifer
and cross the fault zone in the up-gradient direction. Once the zones cross the fault zone, the formation is bedrock and
the groundwater flow direction, hydraulic gradient, and aquifer parameters are likely much different than those
determined for the alluvial aquifer. As such, you must take this change in aquifer type into consideration when
delineating the zones. For the other two Hyde Park Wells, the up-gradient boundary for zones 3 and 4 were delineated
using hydrogeologic mapping and it was assumed that the two zones shared the same upgradient boundary. This is a
very common approach to modeling zones for wells that are near the base of a mountain front. I have attached the final
DWSP plans for the other two Hyde Park Wells for your review. I would expect the delineation for the City Hall Well to
also follow this logic. Please update the delineation reflecting the change in aquifer conditions that occurs at the
mountain front/fault boundary.
If the modified delineation for the City Hall Well results in changes to the potential contamination source inventory, be
sure to update subsequent sections of the plan to address any changes.
Also, before the Division can concur, the Division will need proof that a map of the final zones has been provided
to Hyde Park City to be covered under their ordinance. Even though the well is Hyde Park City's source, we do
need documentation that the city has received the final zones and will be enforcing their ordinance in those areas.
As an aside, I understand from Melissa that there may be some questions about the maximum pumping rate used in
the delineation and how it relates to the equipped pumping rate. Source protection staff do not make determinations on
safe yield nor do we have any say in what a well is equipped at. That decision is typically handled through the well
equipping plan approval process. If you have more questions about the well's equipping pumping rate, please reach out
to Hunter Payne (cc'd on this email).

Morning Deidre,

Considering the specific capacity method T is 6,122 ft2/day, as listed in the current DWSP plan, while the
calculated Cooper-Jacob Method T is 7,853 ft2/day (or 8,105 ft2/day by your calcs), are you okay that we’re
keeping the SC Method T, or we have to update to the Cooper-Jacob T and WhAEM model based on the
new T?

I believe the larger new T will cause a longer and skinnier boundaries, see the attached snapshot for my
quick 250-day model with new T (7,853 ft2/day). Please let me know your thoughts.

Thanks,
Haiming

I would say the Cooper-Jacob method is more accurate for determining T. Also, a higher T is typically considered more
conservative, so I would remodel using the higher T.

Considering the specific capacity method T is 6,122 ft2/day, as listed in the current DWSP plan, while the
calculated Cooper-Jacob Method T is 7,853 ft2/day (or 8,105 ft2/day by your calcs), are you okay that
we’re keeping the SC Method T, or we have to update to the Cooper-Jacob T and WhAEM model based
on the new T?

I believe the larger new T will cause a longer and skinnier boundaries, see the attached snapshot for my
quick 250-day model with new T (7,853 ft2/day). Please let me know your thoughts.

Thanks,
Haiming

Thanks. I reviewed the data provided and calculated a transmissivity of 8,105 ft2/day. It is very close to what you
calculated. I think the only difference may be in how we calculated the delta s over one log cycle. I took the difference
between the drawdown at 100 minutes and the drawdown at 1,000 minutes (change of s over one semi-log cycle). My
value for delta s was a bit different from yours, but I'm okay with what you have calculated for T.

Let me know if you have any other questions before finalizing the plan.

Hello,

I have reviewed the final Drinking Water Source Protection (DWSP) plan for the Hyde Park City Hall Well; however,
before the Division can concur, the following items must be addressed:

Section 2.0 - Delineation Report

A statement is made that the pumping tests are included in Appendix C. Are raw data available? If so, please
provide a copy of the raw data from the constant-rate pumping test. I would like to check the value for
transmissivity derived from specific capacity information with one calculated using the Cooper Jacob method, which
is typically more accurate. The equation is as follows: T = 2.303Q / 4π∆s where T is transmissivity in ft2/day, Q is the
constant discharge rate in ft3/day, and ∆s is the change in drawdown given by the straight line over one log-cycle.
The use of specific capacity will result in an over approximation of the transmissivity, which will result in
longer/skinnier zones when modeled.

Something needs to be done about the upgradient extents of zone 4, and possibly zone 3 (if it crosses the fault
boundary). I apologize I didn't catch this in the PER phase, but zones 3 and 4 extend well beyond the alluvial aquifer
and cross the fault zone in the up-gradient direction. Once the zones cross the fault zone, the formation is bedrock
and the groundwater flow direction, hydraulic gradient, and aquifer parameters are likely much different than those
determined for the alluvial aquifer. As such, you must take this change in aquifer type into consideration when
delineating the zones. For the other two Hyde Park Wells, the up-gradient boundary for zones 3 and 4 were
delineated using hydrogeologic mapping and it was assumed that the two zones shared the same upgradient
boundary. This is a very common approach to modeling zones for wells that are near the base of a mountain front. I
have attached the final DWSP plans for the other two Hyde Park Wells for your review. I would expect the delineation
for the City Hall Well to also follow this logic. Please update the delineation reflecting the change in aquifer
conditions that occurs at the mountain front/fault boundary.

If the modified delineation for the City Hall Well results in changes to the potential contamination source inventory, be
sure to update subsequent sections of the plan to address any changes.

Also, before the Division can concur, the Division will need proof that a map of the final zones has been
provided to Hyde Park City to be covered under their ordinance. Even though the well is Hyde Park City's
source, we do need documentation that the city has received the final zones and will be enforcing their ordinance in
those areas.

As an aside, I understand from Melissa that there may be some questions about the maximum pumping rate used in
the delineation and how it relates to the equipped pumping rate. Source protection staff do not make determinations
on safe yield nor do we have any say in what a well is equipped at. That decision is typically handled through the
well equipping plan approval process. If you have more questions about the well's equipping pumping rate, please
reach out to Hunter Payne (cc'd on this email).

Also, before the Division can concur, the Division will need proof that a map of the final zones has been
provided to Hyde Park City to be covered under their ordinance. Even though the well is Hyde Park City's
source, we do need documentation that the city has received the final zones and will be enforcing their ordinance
in those areas.

As an aside, I understand from Melissa that there may be some questions about the maximum pumping rate used
in the delineation and how it relates to the equipped pumping rate. Source protection staff do not make
determinations on safe yield nor do we have any say in what a well is equipped at. That decision is typically
handled through the well equipping plan approval process. If you have more questions about the well's equipping
pumping rate, please reach out to Hunter Payne (cc'd on this email).

Thanks,

I still haven't had a chance to look at it. It's in our queue and we have 120 days to provide comment. I should be
reviewing it sometime in the next few weeks.

Afternoon Deidre,

We have completed the Drinking Water Source Protection Plan for the new well that was drilled for Hyde
Park City. Presently we are referring to the well as the City Hall Well. The copy attached is not signed yet,
but I will sign and date with your approval. Please let me know if you have any concerns on this plan.
Thank you for all your guidance and expertise!

Regards,

Steven
