Project Spotlight: North Dakota Lead Service Line Inventory

03/18/2024

Project Importance

Lead, once common in pipes delivering drinking water into homes, was banned for this purpose by Congress in 1986. Despite the prohibition, the legacy of lead service lines remains a significant public health concern, particularly for children. Recognizing the urgency, the federal government took substantial steps in 2021, introducing the Lead and Copper Rule Revisions (LCRR) to the Safe Water Drinking Act. A key element of The Biden-Harris Lead Pipe and Paint Action Plan, the LCRR mandates that all public water systems create, submit, and maintain an inventory of lead service lines, playing a crucial role in replacement plans and securing potential funding for initiatives.

B&A’s Role

Burian & Associates is leading North Dakota communities in this crucial initiative to remove lead from drinking water. We provide guidance on the associated issues and are actively involved in developing compliant lead service line inventories for 34 public water systems across the state. Our LCRR compliance approach aims to assist communities in conducting precise inventories using methods that are not only cost-effective and minimally intrusive, but also community centric.

Our approach commences with city staff meetings and a thorough examination of accessible historical records. Following this, we actively involve the public, encouraging their participation in identifying their respective service lines. Our dedicated team employs a user-friendly approach by disseminating educational “do-it-yourself” customized notices, aiding individuals in determining whether lead is a concern in their homes or businesses. This step-by-step method facilitates the collection of critical information and establishes an efficient process for sharing it, which enables our team to confidently assess the accuracy of self-performed analyses and ensure the creation of a comprehensive and precise inventory.

Beyond saving utility operators and managers time, our strategy builds trust between the public and the water utility, raising awareness of a complex and nationwide public health concern. Ultimately, this lays the foundation for ongoing and effective lead service line removal initiatives.

100-Year Flood or Drought: Why Do We Care?

9/20/23

About a month ago, Southern California was hit by Tropical Storm Hilary, the first tropical storm to land in California in 84 years. On August 20, 2023, San Diego had its wettest day on record and Palm Springs set a new record for most rain in a single day. The rain from the storm resulted in flooding, mudflows, sinkholes, and power outages across southern California.

Flooding is a natural disaster that can result in loss of life or property, damage infrastructure, facilities, and agriculture, and affect water and wastewater supply and treatment.  When California was hit back in 1939 by a tropical storm, North Dakota was still experiencing a very different type of extreme weather: drought.  All through the 1930s, North Dakota (and the rest of the Midwest) experienced drought with 1934 and 1936 both setting records for the driest year on record.

One of the ways extreme weather can be categorized is through frequency analysis. The term 100-year flood or 500-year flood might come to mind. This does not mean that an event like the one that just happened in California will only occur once every 10 or 500 years, but rather that the recurrence interval, or chance of it happening in a given year, is 1 in 100 (1%) or 1 in 500 (0.2%). This same idea can also be used to define droughts (chances of it occurring in a certain time frame); however, droughts tend to happen over longer periods when compared to floods. The amount (or lack) of water making up a 100-year flood (or drought) are what engineers use in their planning considerations and design calculations.

Engineers use these extreme weather events, such as the flood in California and the 1930’s drought in North Dakota, when they design flood mitigation or drought resiliency projects. Currently, the Burian and Associates team is part of the consulting team for the Red River Valley Water Supply Project (RRVWSP). When fully constructed, this project will deliver water from the Missouri River in the McClusky Canal via pipeline to the Sheyenne River for communities and rural water districts in central and eastern North Dakota to combat drought and support economic development. Through modeling efforts for the project, our team is using historical information across several climate indicators (including drought and flood years) to analyze water availability leading up to, during, and following drought years.

The RRVWSP is currently under construction and received generous funding support from the North Dakota Legislature in 2023. When completed, the RRVWSP will provide drought resiliency and support economic development for nearly half of the residents in North Dakota. The Burian and Associates Team is excited to be part of and lend their expertise to this very impactful project.
