Deficient Monitoring |
Quarterly sampling for total dissolved solids (TDS) was conducted on 1/3/24 for RSW-002b and sample analysis commenced on 1/4/24, which was within the Standard Method 2540C allowable holding time of seven days. However, the sample for RSW-002b was inadvertently discarded prior to completion of analysis. Due to a laboratory error, RSW-002b was not resampled, rather the original sample collected on 1/3/24 was mistakenly reanalyzed after the 7-day holding time had expired (1/17/24). Although the TDS sample for RSW-002b was analyzed past the allowable holding time, the data result was comparable to historical data at this location. |

Deficient Monitoring |
Due to a laboratory oversight, the commercial laboratory (Weck Laboratories) analyzed the ortho-phosphate-P sample for EFF-001b (which was sampled on 2/6/24) beyond the EPA Method 365.3 allowable holding time of 48 hours (on 3/4/24). However, the ortho-phosphate-P result (0.083 mg/L) was comparable to historical data for EFF-001b. |

Deficient Monitoring |
Due to a sampling error, weekly temperature monitoring was not conducted at EFF-001b, RSW-001b, and RSW-002b during the week of August 15, 2022.The impact on the compliance calculation of the running annual average temperature delta between the discharge brine and the receiving waters was insignificant (as three weekly temperature monitoring events were conducted in August 2022), however, this will be reported as a monitoring violation. |
