4. Might a new, perhaps deeper Love’s Point well access better quality water?

Not likely, or at least not cost effectively.

The Love’s Point Parcels A & B sit at the end of a ridge called Leubow Point. The wells on these parcels were purposely dug to approximately Clear Lake level.

A neighbor on Leubow Point recently dug a well. His first attempt failed because the shaft kept collapsing. His second attempt tapped the same colloidal clay contaminated water as the Love’s Point wells.

All three wells are deeper than 600 feet.

While is it is possible that better water might be found below the aquifer that the three existing wells tap, the risk and cost would be daunting.

It would be possible to dig a well on one or more of the lower Love’s Point Parcels D, E or F. But, nearby existing well have their own issues, namely boron content.

6. How much would it cost to create an automated system for treating LP Parcel B well water ?

Dunken pump provides us with an “preliminary” estimate for a treatment system to produce 5-7 gallons per minute by using a settling tank to drop out sediment before sand filtering.

Dunken’s recommended system might look something like this:

Not at all to scaledunken_config

See Dunken Pumps “itemized” estimate

With sales tax Dunken “preliminarily” estimating $31,000

The Dunken estimate  includes or does not include:

  • Slab only – no covering building/shed
  • Does not include electrical panels, outlets, wiring, installation.
  • Only one solution tank and dosing pump (The Halden system uses two solution tanks and two dosing pumps. A truely effective system might need three sets)
  • No mixing apparatus (mixing solution in the settling tank is recommended)
  • No accounting from calibration time (this can be significant as effective flocculation is a mixture of science and art).
  • Does not include well pump and motor, well piping or installation.
  • Does not include Ozone system for purification and final clarification polish.

A more comprehensive system might look like this:

7. Are there professional consultants available for developing and/or improving the Love’s Point water systems?

Yes

Water Systems Engineer
Tom Sawyer
707 546 7262

Tom is a freelance water system engineer
who comes highly recommended by Brock Dolman
of The Occidental Arts & Ecology Center Water Institute

Tom’s offers expertise in designing and implementing
development of integrated water & power systems.

When I spoke with Tom in September 2007 he expressed
disinterested in residential projects. But, real money and
commitment would likely pique his interest

Dunken Pump
Lakeport, CA
(707) 263-4486

Dunken Pump maintains the only equipment in Lake County
capable of serving a 600-700 foot well. They offer comprehensive
pump and water treatment systems services.

Dungeness Development Associates, Inc.
John Macpherson
206-730-5370

Specializing in construction run-off water treatment.
Dungeness offers expertise probably more suited to the Love’s
Point special water clarification needs than conventional water
purification companies (for example, Culligan could not help us).

Dungeness supplies a chitosan flocculant product.

Vanson supplies chitosan flocculant and offers
system design assistance. They recently provided
a dose analysis from a sample of the Love’s Point water.

8. Are there other ways to clarify the Love’s Point well water?

No, not cost effectively.

• Simple filtration does not work because the colloidal clay is too finely grained. It either passed through the filter or clogs it too quickly.

• Sand filtration works because such filters allow for automated back flushing and work effectively with flocculation agents.

• Vanson has experimented with centrifugal filters, but found that the process breaks down the floc rendering it ineffective.

• There is a process called D.A.F. (dissolved air floatation) that would almost certainly replace the need for a settling tank and might reduce the demand for floc use. However, the D.A.F process would still require sand filtration for final clarification, and even a small D.A.F. unit would cost in excess of $50K alone.

9. Are there alternatives sources of water for the Love’s Point Parcels other than well or lake water?

Yes

http://www.harvestingrainwater.com/

Rain harvesting

Advantages

  • minimizes water processing
  • minimize need for floc agents
  • minimize maintenance
  • eliminate (or minimize) need for flocculation agents minimize electrical power demand
  • could provide gravity feed to users
  • provide a fundamental, tangible focus for cooperation between Love’s Point “owners

Require

  • fundamental attitude and life style change of users
  • collection and storage infrastructure

Water: Source – Well

The Love’s Point well draws from an aquifer
apparently connected to nearby Thurston Lake.

This photo provides an accurate depiction of the water color

This photo shows the Love’s Point House pool filled with un-treated well water.

The pool is not normally filled
due to leaks and the expense of processing water.

Though registering on the alkaline side of the pH scale,
and is highly turbid with a colloidal clay,
the well water has proven suitable for agriculture and landscaping use.

However, for domestic use,
the well water must be clarified.

Water: Processing for Domestic Use

Love’s Point domestic water is processed in two phases:

1. Clarification
2. Purification

Clarification

Sediment suspended in the Love’s Point
well water is too finely grained to be
effectively filtered.

It must be clarified by mixing the water
with a flocculant, i.e. an polymer additive
that attracts small particles into larger “clumps”
that can be then effectively filtered or gravity settled.

The Love’s Point well water is primitively processed by:
1. manually activating transfer pumping from
well to treatment tank
2. manually dosing with a non-toxic flocculant
derived from crustacean shells.
3. manually activating several mixing processes
4. manually activating transfer of clarified water
to the purification/storage tank.

• Required frequency of the process
depends entirely on water usage
which can vary widely
from user to user and from season to season.
Storage tank levels must be monitored regularly
(even daily) until a pattern is noticed.
Historically, with four light users,
processing was required every 4-6 days.
With two light users, every 8-12 days.

Sample Log of Clarifying Process

Purification

  • Clarified water is pumped into a 2,500 gallon storage tank where it is Ozone treated using a O3 bubbler.
  • This Ozone treatement also “polishes” the clarifiction process.
