Our Services

We aim to cover all Monitoring and Reporting Program responsibilities imposed by the State Water Board so wineries can focus solely on producing wine. Depending on winery process water volume and methods of discharging, this can save winery staff hundreds of hours per year monitoring between 400 and 850 parameters.

 

A number of parameters can be measured on-site, while others must be analyzed by a state approved laboratory, and some are simply an observation recorded. Some samples must be taken weekly, while others only require annual collection, and various monitoring requirements vary by the season. At Northern Water Services we make it our business to know when, where, and what to sample so that winery activities may flow smoothly and uninterrupted. 

Report Submission

Wineries are required to submit monthly compliance letters, annual reports, as well as semi-annual reports for Tier 4 facilities. Reporting monitoring data requires the date, sample location, constituents, concentrations, and observations to be readily discernible, and the data should be summarized to clearly illustrate whether the winery complies with the Winery Order and facility Notice of Applicability. We take this very seriously at Northern Water Services, as "failure to submit technical or monitoring program reports, including but not limited to, Compliance Letters as described herein or falsifying information is guilty of a misdemeanor and may be subject to enforcement action."

On-site pH, EC, and DO analysis

pH, EC, and DO require the most frequent sampling, ranging from 124 to 260 recordings throughout the year, and must be done in the field as values can change rapidly in a sample container. We have more than a decade of combined experience using probe-based meters, with conservative calibration procedures in place to increase accuracy.

Laboratory Sample Collection

Wineries can expect between 83 and 218 parameters to be monitored by a state approved laboratory each year, depending on wastewater volume, winery and wastewater infrastructure, and discharging practices. This includes Fixed Dissolved Solids, Total Dissolved Solids, General Minerals, Biochemical Oxygen Demand (BOD), TKN, Ammonia, Nitrate, Nitrite, Nitrate + Nitrate as N, and Total Nitrogen. We follow sample collection, handling, and preservation methods in accordance with approved U.S. EPA analytical methods to ensure sample integrity.

 

Sample Delivery

Timely delivery of samples is essential for accurate results, especially for BOD. BOD represents the amount of oxygen consumed by microorganisms while they decompose organic matter, and they don't wait for sample delivery to continue doing their processes. We ensure same day collection and delivery to state laboratories for maximum accuracy.
