Current State of Tap Water in New Hampshire
New Hampshire’s tap water is subject to strong safety regulations, but it still faces challenges related to contaminants like PFAS, lead, and copper. The state’s ranking at #41 for drinking water quality highlights ongoing issues, particularly in rural areas where aging infrastructure and pollution from agriculture and industry contribute to water quality concerns. Although many public water systems meet safety standards, some private wells and municipal systems continue to struggle with contamination levels that exceed federal guidelines. Recent studies indicate that over 75% of New Hampshire’s private wells are at risk of contamination, particularly from bacteria, heavy metals, and chemicals like PFAS. The state is also grappling with the effects of agricultural runoff and industrial pollutants, which are compromising water quality across many communities.
Overview of NH Water Sources
New Hampshire sources its tap water from a variety of places, including surface water like rivers and lakes, as well as groundwater from aquifers. The state is known for its abundant natural water sources, with more than 83,000 miles of rivers and streams. However, these sources are under constant pressure from industrial waste, urban development, and agriculture. For instance, nearly 30% of rivers in the state do not meet the EPA’s standards for water quality, and agriculture-related pollution, including runoff from fertilizers and pesticides, continues to be a significant problem.
More than 33% of rivers and streams in New Hampshire fail to meet water quality standards, with 28,000 miles of waterway affected by pollution.
Recent Water Quality Reports
New Hampshire’s water quality is periodically monitored, with annual reports provided by the New Hampshire Department of Environmental Services (NHDES) for public water systems. These reports provide valuable information on contaminants like lead, PFAS, and bacterial levels, which can pose health risks to residents.
Recent beach inspections have raised alarms over high levels of fecal bacteria in popular swimming areas such as Chase Beach and Northwood Beach. Infected water can lead to gastrointestinal diseases and skin rashes, prompting increased monitoring by state agencies.
Chase Beach and French’s Park Beach were flagged in 2022 for fecal bacteria levels above the acceptable limit, leading to temporary closures during summer months.
PFAS Concerns in NH Communities
PFAS (per- and polyfluoroalkyl substances) remain a major concern for water safety in New Hampshire, particularly in areas near industrial sites and military installations. PFAS, often referred to as "forever chemicals," can linger in the environment and accumulate in the human body over time, potentially leading to cancer, liver damage, and developmental issues in children.
Testing in communities like Merrimack and Litchfield has revealed PFAS levels exceeding the federal advisory limits, which has led to increased efforts from state and federal agencies to provide clean water alternatives and filter systems.
Over 19% of public water systems in New Hampshire have reported PFAS contamination above the federal limit of 4 ppt.
Lead and Copper Levels
Lead and copper contamination continues to be a concern, particularly in older homes with lead pipes or copper plumbing. While municipal systems generally adhere to EPA guidelines for these metals, homes built before 1986 are at greater risk, and more frequent testing is required.
Recent reports indicate that about 15% of homes built before 1986 still have lead pipes, which can release harmful levels of lead into drinking water, especially when the water is corrosive.
About 15% of homes built before 1986 in New Hampshire still have lead pipes or fixtures, contributing to potential contamination risks.
Municipal Water Treatment Processes
The municipal water treatment process in New Hampshire involves several stages: coagulation, sedimentation, filtration, and disinfection. These processes are designed to remove harmful bacteria, viruses, and chemicals from water sources. However, concerns remain about the effectiveness of these treatments in eliminating PFAS and other persistent contaminants.
The New Hampshire Department of Environmental Services (NHDES) works in tandem with local utilities to ensure that water treatment plants meet the required standards. In areas affected by PFAS contamination, additional filtration systems have been installed, including activated carbon filters and reverse osmosis systems.
In 2022, the NHDES allocated $12 million in grants to local municipalities to help install advanced PFAS filtration systems in heavily affected areas.
Understanding New Hampshire's Water Quality Standards
We know how vital New Hampshire’s water quality standards are. They keep our tap water safe. The federal Safe Drinking Water Act sets a base for water quality. New Hampshire goes beyond that with its own rules.
The EPA and the New Hampshire Department of Environmental Services enforce these standards. They make sure we have clean drinking water.
New Hampshire has strict rules to protect its water. The Water Quality Shoreland Protection Act requires a 50-foot "Waterfront Buffer." This area limits tree removal near water bodies.
Also, the "Alteration of Terrain" rules stop stormwater pollution within 100 feet of water sources. These rules help keep our water clean.
Here are some ways to protect New Hampshire’s water quality:
- Vegetative buffers to prevent pollutants from entering water bodies
- Minimum land use setbacks from certain surface water sources and tributaries
- Restrictions on stormwater discharges in sensitive areas
These steps are key to keeping our water clean. By following these rules, we help keep our tap water safe. And we protect New Hampshire’s natural beauty.
Common Contaminants and Health Considerations
In New Hampshire, we find many water contaminants. These include PFAS, lead and copper, and natural minerals. These can harm health, mainly for kids and those with weak immune systems.
PFAS Concerns in NH Communities
PFAS, or per- and polyfluoroalkyl substances, are linked to health issues. This includes cancer and problems with reproduction. It’s key to test for PFAS in drinking water to keep it safe.
Lead and Copper Levels
Lead and copper can get into water from old pipes and fixtures. This is risky for health. Homeowners with old plumbing should test their water for these metals.
Natural Mineral Content
Natural minerals like iron and manganese can change water’s taste and smell. While not usually harmful, high levels can make water look or taste bad.
The table below shows common water contaminants and their health risks:
| Contaminant | Potential Health Effects |
|---|---|
| PFAS | Cancer, reproductive issues |
| Lead | Neurological damage, developmental issues |
| Copper | Gastrointestinal problems, liver damage |
| Natural minerals (e.g., iron, manganese) | Aesthetic issues (taste, odor, color) |
Testing and monitoring drinking water regularly can spot contaminants. This helps avoid health risks. Homeowners and communities should act to keep their water safe and clean.
