LWP takes water quality very seriously and continuously strives to ensure safe, clean drinking water for our customers. The following, Water Quality Report provides important information regarding water quality, water service and contaminant levels to Loveland customers.
LWP is proud to report that the water provided to the community meets or exceeds established state and federal water quality standards. For a previous version of the report or to request a hard copy call us at 970-962-3000.
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 five SolarBee SB10000s mixers in Green Ridge Glade Reservoir.
- Water Quality staff completed a powdered-activated carbon optimization study to improve taste and odor removal.
- Water Quality staff increased taste and odor monitoring at the intake structure to the Loveland Water Treatment Plant.
- LWP has contracted with a lake management company to apply algaecide to Green Ridge Glade Reservoir in the event of an unforeseen bloom.

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.
Loveland Water and Power (LWP) participates in all aspects of the Lead and Copper Rule from the moment the source water enters the plant until it comes through the taps of Loveland residents. Staff tests lead and copper, at the Water Treatment Plant and in designated homes. In 1991, LWP set up 60 sample sites in homes throughout the distribution system to test annually. Because of low lead and copper results, over the first three sampling events, LWP was given a reduced sampling plan that now consists of 30 samples from those 60 homes. These sites were chosen to reflect a variety of homes, new and older houses with copper piping and lead soldering and some with lead service lines. The sampling protocol is performed to reflect “worst case scenario”, and is done after water sits in piping for 6-8 hours with no water use.
The EPA has set action levels (AL) of 0.015 mg/L (milligrams per liter) for lead and 1.3 mg/L for copper, based on the 90th percentile. An exceedance of an AL is not a violation, but can trigger other requirements such as community education programs. A community water system may exceed ALs in 10% of samples taken. Since the Lead and Copper Rule was established, Loveland has never, exceeded ALs in 10% of our samples.
To monitor the corrosiveness of the treated drinking water, the staff of the Water Treatment Plant and Water Quality Lab, checks both alkalinity and pH, analyzing pH continuously at the plant and throughout the system numerous times daily. Lead and copper analysis, along with pH and alkalinity are performed over and above what is required by the state and the EPA at the Water Treatment Plant.
Water Distribution crews check lines for lead piping and lead soldering whenever they repair mains or fix leaks. If they find any sign of the potential of lead while inspecting water meters and city service lines, they replace the meters and piping immediately. This practice has added an additional layer of protection to the city’s Lead and Copper Program.
How To Reduce Lead in Drinking Water
- Flush your pipes before drinking
- Only use cold water for eating and drinking
- Know that boiling water will NOT get rid of lead contamination
- Learn more about measures you can take to reduce lead in your drinking water from the EPA
