Data center water stress

Richmond County has 2 facilities in the DCWSI dataset.

ByCounty's DCWSI ranks this county #N/A nationally by combining its water score with mapped data center density.

DCWSIThe Data Center Water Stress Index: 60% the county's water-system stress plus 40% how concentrated data centers already are, scored 0-100. Higher means data-center density and water pressure overlap more here.

Editorial analysis

Understanding Richmond County’s Water

Drinking Water Quality Overview

EPA SDWIS

Richmond County has limited drinking water data on file. Violation data are unavailable for this county.

Monitoring Network

EPA WQP

EPA's Water Quality Portal (WQP) aggregates monitoring data from federal, state, and tribal agencies. Richmond County has moderate coverage with 18 active monitoring sites with 5,812 recent measurements on record. Predominant monitoring categories include physical and microbiological. More monitoring sites generally indicate greater scientific attention to local water conditions — and provide the baseline data that regulators use to set future impairment listings.

Editorial advisory

What the data suggests for Richmond County

Water Verdict

Richmond County does not have sufficient EPA SDWIS water quality data to determine an overall assessment. Residents should contact their local water utility for the most recent Consumer Confidence Report.

Violation Context

Health-based violation data is not available for Richmond County. EPA health violations occur when water systems exceed allowable contaminant levels or fail to meet treatment requirements. Residents should request the latest Consumer Confidence Report from their water provider.

Consumer Guidance

Drinking-water compliance data is not yet available for Richmond County in the EPA SDWIS system, which is common for rural areas and census areas served by private wells or small tribal systems. Residents should contact their local utility or state drinking-water agency for the most current Consumer Confidence Report. Using an NSF-certified filter (look for certifications against ANSI/NSF 53 or 58) can provide additional safety margin for any unconfirmed contaminants. A pipeline streamflow snapshot from the RICHMOND CREEK gauge is also available on this page.

Regional Context

State-level water quality comparison data is not available for Richmond County. When data is available, this section will show how the county's water quality compares to other counties in New York.

Advisory text summarizes county-level public records and is not a replacement for your utility's current Consumer Confidence Report or direct local notices.

Frequently Asked Questions

What is the water quality in Richmond County, New York?
Richmond County, New York has a drinking-water quality grade of N/A with a score of N/A/100, based on EPA SDWIS compliance data. Compliance data is currently unavailable. Watershed health, monitoring records, and streamflow snapshots are reported separately on this page.
Are there any water violations in Richmond County?
Violation data for Richmond County is not currently available. Health-based violations indicate instances where contaminant levels exceeded EPA Maximum Contaminant Levels (MCLs).
How much water-quality monitoring happens in Richmond County?
EPA's Water Quality Portal records 5,812 measurements from 18 monitoring sites in Richmond County over the past five years. The most frequently measured characteristic groups are Physical, Microbiological, Nutrient. Each measurement is a single sample analyzed for one characteristic (E. coli, pH, dissolved oxygen, etc.). High monitoring density means more scientific evidence behind any reported signal — it does not by itself indicate water quality.
How does Richmond County water compare to the New York average?
Richmond County's SDWIS water quality score of N/A/100 is not available for comparison. The average water quality grade across New York is D, based on data from 57 counties with available SDWIS data.
Is tap water safe to drink in Richmond County?
Based on EPA SDWIS data, Richmond County has a water quality grade of N/A (N/A/100). Insufficient data is available to fully assess compliance. The grade speaks to the public water system, not the watershed — for watershed-level concerns, see the Watershed Health zone. For the most up-to-date information, contact your local water utility or review your Consumer Confidence Report (CCR).
Does Richmond County have clean drinking water?
Richmond County has no reported health-based drinking water violations according to EPA records. With a water quality score of N/A/100 and grade N/A, the county's drinking water has had some compliance issues but continues to be monitored. Note: drinking-water compliance speaks to the public water system, not necessarily to the watershed itself — check the Watershed Health zone for ATTAINS §303(d) data.
How is water quality measured?
WaterByCounty layers four federal datasets per county. The A–F drinking-water grade comes from EPA SDWIS (Safe Drinking Water Act compliance, 5-year violation lookback). The Watershed Health zone surfaces EPA ATTAINS §303(d) impairment data. The Monitoring zone summarizes EPA Water Quality Portal records. The Streamflow zone reports the latest USGS NWIS reading from the county's primary streamgage. Each is reported separately so you can see where the water is actually weakest.

Data Sources

Drinking-water compliance data from the EPA Safe Drinking Water Information System (SDWIS) via the ECHO enforcement database. Scores reflect compliance history and health-based violation counts.

Water-quality monitoring counts from the EPA Water Quality Portal (WQP), federated USGS, EPA, and state agency sampling records over a rolling 5-year window.
