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.

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 scale

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:

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.

Back to FAQ –>

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.

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

Love’s Point draws it’s water from a 660 ft well.

• irrigation water is drawn directly from the well
• domestic water must be processed
