Maybe look on the report for an item called "total turbidity" as it will have some effect on the TDS. Total dissolved solids can also include weird little things like MUD! I was asked at a neighborhood meeting to explain what turbidity meant and I (being the blind fool) mentioned that it was the amount of dirt or mud in the water. Since we used wells and wells are in the ground, I kind of thought having some dirt in the water was normal. That lady sure set me straight and let everybody know I didn't have any idea what I was doing since their water came out of pipes, not the ground!
I was wondering about total turbidity. Once you mentioned it, I decided to try and figure out what it is. It seems to be a pretty elusive subject with an odd way of measuring it. It is measured in Units (NDU and formerly JDU) which is a measurement of refraction of light by the undissolved particles in water. The benchmark is 1 ppm of silica = 1 unit which seems to be deceptive since silica is highly reflective. No way to really know how that equates to actual ppm because different substances refract light differently. Still it is very interesting. The range for my area is NDľ0.69 with an average of 0.18. Seems kinda low since my water is sourced from wells.

The CCR does give high, low, and average measures. I used the averages in my quoted values. I feel that many of the readings are probably currently higher than average due to drought in California.

One of the things we are going to see come to a head is that we are polluting water faster than we are cleaning it. I might guess that you would be found in the Central Valley area but that isn't to blame the local farmers as we all live downstream from somebody and if you are on a well, the surface water is kept from entering the well directly, so that means the nitrate in your water may be from hundreds of miles away and any the local farmers add, may come out in Arizona!
You hit the nail on the head. I do live in the Central Valley. Marysville is surrounded by a levee and has both forks of the Yuba river on two sides and Rice fields surrounding the rest. I am sure that the water table is a combination of river water and runoff from the farms. I believe that the Yuba river was not used for city water because of Mercury in the water from the Gold and Silver mining upstream. Interesting note, the rice grown here is highly sought after in China and Japan because of the very low Mercury levels.

I agree that water is our future and we need to do all we can to protect it.

My regulator arrived and it is a beast. Much larger than I anticipated. Will post a photo of my parts in next post.
