Water Supply Situation

Well #3 In Service; Problems with #5 Video Inspection

To reduce the load on well #6, well #3 was put in service a little before noon on 12/2/2016. So the arsenic levels in your water will probably exceed limits while well #5 is out of service.

The video inspection of well #5 was started and cut short when the camera quit working at about 200′. (The well is 771′ deep.)

Plan to Run Well #3 Starting Noon Friday, 12/2/2016

To avoid water shortages while our primary water source, well #5, is being repaired, at noon on Friday, December 2, we will begin supplementing water from our only active well (#6) with water from well #3. Because water from well #3 exceeds the current limits for arsenic, the arsenic levels in your water will probably exceed limits while well #5 is out of service. See the November 2016 WaterGram, distributed with water bills, and reproduced below.

Because each well feeds directly into the distribution system, there is little opportunity to mix water between wells. So all residents should expect that they will be receiving water (up to about 27 parts per billion, ppb, of arsenic) that exceeds the arsenic limit (10 ppb), for the next several weeks.

Although water from well #3 exceeds current federal and state standards, it is well within the older 50 ppb standard and was considered safe for many years. Some issues to consider:

  • Arsenic levels between 10 and 50 ppb are a potential health concern only with many years of continuous exposure.
  • Arsenic in drinking water is of no concern if you use water from a reverse osmosis (RO) system for cooking and drinking. These systems remove arsenic and most other materials.
  • You can also avoid any concerns with arsenic by using bottled water for cooking and drinking.
  • Arsenic cannot be removed by boiling.

A video inspection of well #5 is planned for Friday, 12/2/2016. From that, we will have a much better idea of the time and effort needed to put #5 back into service.

Well 5 Out of Service

On Tuesday, 11/29/2016, our main well, #5, was taken out of service and the pump pulled up. We ran all day on just well#6, and will do that again Wednesday. Demand appears to be more than it can provide alone.

Well 3 May Be Put In Service

Sometime the week of November 28, 2016, we may have to put well #3 into service on an emergency basis. This well produces arsenic above the current limits (see November 2016 WaterGram, below), so has not been used for years.

The plan is to begin inspection and rehab work on our main well, #5, starting Tuesday, November 29, 2016. The down well equipment (pump, motor, cables, pipes, etc) will be removed, and then the well service company will do a video inspection of the entire well.

Current water demand is just about what our remaining well, #6, may be able to supply. So we will try using just #6, watching it very carefully, and turn well #3 on only if necessary.

Well 3 Testing

To get ready to put well #3 into service later in November, we will be running it periodically, dumping the produced water onto the ground. So do not be surprised if you see water there (64 Camino Manzano).

We have a significant problem

The Coop has two working wells (#5 and #6). Roughly two thirds of our water comes from #5. As we have reported for several years, if something happens to well #5, we will be unable to provide adequate water to our members. This is because well #6 cannot supply sufficient water and our storage tanks only last for a few days.

Recently, we identified a problem in well #5. The source of the problem must be identified and corrected before there is damage to the well. Identifying the problem will require the removal of 500 feet of pipe, the pump, the pump motor, and the electrical cables. When this is done, a careful video inspection of the well will be necessary. Depending on the nature of the problem, it will require two weeks to as long as two months to fix the problem and put the well back in service.

Well #3

Well #3 (located in Sundance Mesa) was drilled in 1998. It can easily provide all of the Coop water needs. Unfortunately, it has about 27 parts per billion (ppb) of arsenic and it had to be taken out of service when the Federal standard for arsenic was lowered from 50 ppb to 10 ppb in 2006. Although we haven’t used this well for the last 10 years, the Coop has carefully maintained it so it can be used in case of emergency. The need to shut down and repair well #5 is such an emergency.

To ensure uninterrupted service during the repair of well #5, we will need to supplement the water from well #6 with water from well #3.

Concerns with using well #3

Although water from #3 exceeds current Federal standards, it is well within the older 50 ppb standard and was considered safe for many years. Some issues to consider:

  • Arsenic levels between 10 and 50 ppb are a potential health concern only with many years of continuous exposure.
  • Water from our wells is fed directly into the distribution system. This means that water from well #3 will be diluted by water from well #6. The amount of this dilution will vary with the total demand for water, your location in the system, and when our wells are running.
  • To the extent possible, we will minimize the use of water from well #3.
  • Arsenic in drinking water is of no concern if you use water from a reverse osmosis (RO) system for cooking and drinking. These systems remove arsenic and most other materials.
  • You can also avoid any concerns with arsenic by using bottled water for cooking and drinking.
  • Arsenic cannot be removed by boiling.

You will be notified when we turn on well #3

  • Notices will be posted on the bulletin boards by the mailboxes.
  • You will receive an e-mail if you have requested to be on the Coop e-mail list.
  • We will also send occasional e-mails and post progress information here on lamesawatercoop.org.
  • We expect to begin work on #5 in the last half of November. When work begins we will turn on #3 and use it as needed until #5 is repaired and returned to service.

New water rates are effective January 1, 2016; see Rate Schedule (2016).

Prior rates: Rate Schedule (2015) and for 2012 through December 31, 2014, see the Rate Schedule (2012).


Leak Policy

If you have a large water bill because of a leak or some other failure, you may be eligible to have your bill re-computed with a flat rate, spelled out in the Policy on Extraordinary Water Use, which applies to all water bills dated on or after January 31, 2016,


Septic Systems

The US Environmental Protection Agency has some very useful information about septic systems on a web page called SepticSmart. You may want to print the one page flyer, “The Dos and Don’ts of Your Septic System“.

You may also want to see the New Mexico Environment Department web page on Liquid Waste Program (Septic Tank Program).


Emergency Contact List

Occasionally we have disruptions in service or other situations where we need to urgently communicate with our members. We are establishing an email list to notify members of water emergencies and other issues in their immediate neighborhood. The list will not be used for any other purpose. The list is voluntary, but we urge you to take advantage of this opportunity. If you wish to be on the list, send your e-mail and street address to alerts@lamesawatercoop.org.

We can also send you an alert as a text message to your cell phone. If you would like that, please send your cell phone number and your carrier (Verizon, AT&T, etc.) to alerts@lamesawatercoop.org.
