ALERT: NID's Poison in Our Water


One of 62 sites where NID drips aquatic herbicides

Many months ago I had a conversation with longtime Penn Valley farmer, Mike Pasner. He was understandably irate over the irresponsible behavior of our local water supplier, the Nevada Irrigation District, and had been collecting data so as to alert the public to NID's deleterious activity: they have been putting herbicides, including Round Up, into our ditches used for irrigation.

How many residents know this? How many people know this when they are walking the canals with their dogs and their best friend laps up the "fresh" ditch water? How about the wild life? Or residents who water their "organic" gardens with water quietly laden with toxins? Or when their children turn on the sprinkler to play in the water during the hot summer afternoons?

This is beyond irresponsible and not only must NID stop this dangerous practice, the majority of the NID board needs to be replaced (except for Nancy Weber who is the only one actually representing her constituents). Here's Mike Pasner's letter: None of these toxins makes it into my organic farm’s irrigation system! I’ve farmed in Penn Valley for 31 years. This treatment to kill algae occurs once a month for the six month irrigation season, April 15th - October 15th. For the first 28 years Nevada Irrigation District (NID) ditch tenders turned off my ditch box without fail on poison day. The last 3 years the liability to shut it off has been shifted wholly onto me.

The terrestrial herbicide used to kill weeds is sprayed on the banks, berms, and water. This treatment is done before and after irrigation season.

Nevada Irrigation District maintains 450 miles of raw water conveyance systems. 350 miles of this system is treated with aquatic and terrestrial herbicides.

I’m still in the process of assembling maps obtained by the public records act. It appears that approximately 50 miles of this 450 mile conveyance system are what NID calls “Randoms”. A Random is a natural creek.

Question: Is it legal to dump liquid herbicide into a natural creek?

Question: Are there enough weed blockages in a free flowing stream to mandate herbicides?

NID is registered with Nevada County agricultural department for use of 23 chemicals. That is 216.18 pounds and 4,665.01 gallons of materials in 2016. Since there are 62 delivery points, I am worried that the concentration at these delivery points is toxic to livestock, fish and wild animals.

There’s no way a mountain lion should be drinking aquatic algaecides once a month. No one wants to eat beef that drank aquatic algaecides once a month.

Cutrine and Nautique are the aquatic herbicides applied above my farm. Many of these algaecides are high in elemental copper. This mix can be hazardous to humans, domestic and wild animals and fish. I used to see fish and newts in our ditch, yet I haven’t for many years.

Roundup Custom is sprayed on the banks, berms, and water. This substance is labeled a probable carcinogen by the World Health Organization and now by the EPA.

Nine of NID’s domestic water treatment plants are supplied by these conveyances.

NID’s Mission Statement:“The District will provide a dependable, quality water supply; continue to be good stewards of the watersheds, while conserving the available resources in our care.”

At a recent Maintenance and Resources meeting, I asked, “Wouldn’t a reduction in herbicide use be part of achieving this mission?” The answer was yes. In the 31 years I have farmed here I have not seen a reduction.

After attending these meetings for years I have come up with a workable fix. Resume cleaning the ditches with small excavators as needed. This was done annually for many years and only stopped 3 years ago. If the banks and berms need vegetation removal, goats are a good way to do it. I have presented this theory to NID management and employees for many years. The only response I have received is, “It isn’t financially viable.” I believe it is! When you eliminate, application equipment, human applicators, training, licensing, registrations, legal testing requirements, herbicides and liability, it becomes a viable option. The liability aspect of this plan has not been analyzed. This represents a huge tab never itemized by NID. The use of these highly toxic substances in water and on land has to have a large liability.

The BOD meeting is Wednesday, June 28th, at 9:00 AM at NID’s main office. Live streaming video will finally be allowed on the agenda after a 4 month, very well publicized battle. Thank you Nevada Irrigation District, for hearing your constituency! Later, in this same BOD meeting, NID will adopt their new Vegetation Management Plan. Now is a good time to tell them your concerns.

To wean NID off their herbicide use may take years. Like live streaming, it will only happen when a sufficient number of concerned rate and taxpayers make themselves heard.

Please lend support and stay in touch with this effort at safeditches@gmail.com.

People are 96% water. Shouldn’t we find alternatives to putting poison in water that is used by people, animals, and crops?

I am a local organic farmer, having lived here for 31 years. I’m not a chemist, a journalist, or a cartographer. When something is wrong it’s wrong to not fix it!
