[ARCHIVED] Latest Manganese Update

We would like to update our customers on our latest monthly manganese results to keep everyone fully informed. The June 9th finished water manganese level was 0.27 mg/l or 270 ppb. The subsequent July 12th finished water manganese level was 0.34 mg/l or 340 ppb which is above the 0.3 level. The primary reason for this increase and really the crux of all our continuing dirty water complaints, is that one of our primary wells Home Farm 6-1 continues to increase in manganese levels. With the dry weather conditions, the ground water level drops deeper and more manganese is being drawn into this well source. The manganese level at this one well is 1.2 mg/l or 1200 ppb. This water is obviously blended in with all other well sources but with this high level it inhibits our ability to adequately sequester the manganese with our liquid linear phosphate. So any disturbance small or large causes dirty water complaints from our valued customers. This source basically represents 1,000,000 gpd (gallons per day) and we cannot fully replace that volume at this time of year. We have worked to minimize its use as much as possible.
We will be cleaning and resurging this well along with another chemical process to inhibit manganese this fall but the process takes up to two weeks and cannot be undertaken during the summer. Thank you for your continuing patience and understanding.
