LWP takes water quality very seriously and continuously strives to ensure safe, clean drinking water for our customers. The following provides important information regarding water quality, water service and contaminant levels to Loveland customers.

Water Quality Report

LWP is proud to report that the water provided to the community meets or exceeds established state and federal water quality standards.

Water providers are required by the 1996 Safe Drinking Water Act to prepare annual reports about the quality of water delivered to the public. To obtain a hard copy please call (970) 962-3000.

Frequently Asked Questions:

Monthly Drinking Water Analysis:

Algae:

Green Ridge Glade Reservoir, LWP's source water storage, does experience naturally-occurring, seasonal algae blooms. Typically algae blooms occur in the late spring, but due to a number of environmental factors such as sunlight and temperature, algae blooms may occur at unexpected times of the year. For similar reasons, some algae blooms are more intense than others.

Algae releases taste and odor compounds that are normally absorbed by carbon during the water treatment process. During an algae bloom, or increase in algae, taste and odor compounds can make it through the treatment process. While it may not be aesthetically pleasing, it is not harmful. 

In 2015 and 2016, LWP experienced the largest algae bloom and taste and odor events in Loveland's history. Those events lead to a comprehensive study for algae mitigation and taste and odor reduction.  

As a result of the study, LWP implemented several strategies to help reduce algae-related taste and odor.

  • LWP installed four SolarBee SB10000s mixers in Green Ridge Glade Reservoir.
  • Water Quality staff will begin a powdered-activated carbon optimization study to improve taste and odor removal with an anticipated project completion of Aug 2017.
  • Water Quality staff will increase taste and odor monitoring at the intake structure to the Loveland Water Treatment Plant.
  • LWP will contract with a lake management company to apply algaecide to Green Ridge Glade Reservoir in the event of an unforeseen bloom. 

The Algal Mitigation Assessment was presented at the May 23, 2017 City Council Study Session.

Chlorine:

Chlorine is the primary disinfectant used by LWP to prevent bacteria such as Legionnaires’ disease and E. coli from entering the water system. LWP adheres to regulations and requirements published by the Colorado Department of Public Health and Environment (CDPHE) and the Environmental Protection Agency (EPA) to ensure the removal of pathogens while maintaining the minimum level of chlorine allowed in the distribution system. 

In April 2016, the CDPHE and the EPA revised the rule that oversees the minimum chlorine level, increasing it over the prior regulations. In response, LWP increased the minimum chlorine residual, in our system to comply with these new standards. The CDPHE and EPA also regulate maximum levels for chlorine in drinking water. The chlorine level in our system, is significantly below the maximum allowed. At no time has LWP exceeded the maximum safe level for chlorine in drinking water. 

Loveland’s treated drinking water starts at the  Water Treatment Plant (WTP), on the west side of town, and travels to the east. As water travels through the city chlorine levels decrease. In order to maintain the required minimum level, throughout the system, chlorine levels must be higher leaving the WTP, on the west side of town.

Lead and Copper:

LWP is proud to report that the water provided to the community meets or exceeds established state and federal water quality standards including the Lead and Copper Rule.

The Lead and Copper Rule was established in 1991 to protect public health by minimizing lead and copper levels in drinking water by reducing water corrosivity. Learn more.
